HORSCH will not assume liability for any damage or malfunctions resulting from failure to comply with the operating instructions. These operating instructions will assist you in getting to know your machine and in using it correctly for its intended purposes. First you are given general instructions in handling the machine. This is followed by chapters on care, description, adjustment and maintenance. The operating instructions must be read and observed by everyone authorised to work on or with the machine, e.g. ¾ operation (including preparation, fault rectification during work and servicing). ¾ maintenance (maintenance and inspection) ¾ transportation. Warranty claims Warranty claim forms must be submitted through your local HORSCH dealer to the HORSCH Service Department in Schwandorf. Only claims, which have been correctly completed and submitted no later than four weeks after the defect occurred, can be processed. Exchange parts, which require the old part to be returned, are marked with the letter "R". Please return these components cleaned and emptied to HORSCH within 4 weeks together with a warranty claim form and precise fault description. Parts deliveries without used parts request: Please keep such parts for 12 weeks, until a decision has been made on the action to be taken. Warranty repairs, which are to be carried out by a third-party company, or which are expected to take longer than 10 working hours, must be agreed upon in advance with the Customer Service Department. Together with the operating instructions, you also receive a spare parts list and a machine registration form. Field service technicians will instruct you in the operation and care of your machine. After this you should return the machine registration form to HORSCH. This confirms your formal acceptance receipt of the machine. The warranty period starts with the date of delivery. We reserve the right for alter illustrations as well as technical data and weights contained in these operating instructions for the purpose of improving the machine. 4

11 Intended use The machine is state-of-the-art and designed in accordance with relevant, recognised safety regulations. However, risks of injury to the operator or third parties and impairment of the machine or other tangible assets can occur during use. The machine must only be operated for its intended use if in a technically perfect condition, whilst being aware of safety and risks and in strict compliance with the operating instructions! Faults, particularly those which impair safety, must be remedied immediately. The machine must only be operated, serviced and repaired by persons who are familiar with it and have been made aware of the dangers involved. Genuine spare parts and accessories from HORSCH have been specially designed for this machine. Spare parts and accessories which are not delivered by us, have not been tested or approved by us. Installation or use of non-original HORSCH products may have a detrimental effect on specific design features of the machine and impair the safety of machine operators and the machine itself. HORSCH will not assume liability whatsoever for damage resulting from the use of non-original parts and accessories. Intended use also includes the strict compliance with the operating instructions and adherence to the operating, maintenance and repair instructions specified by the manufacturer. Consequential damage The machine has been manufactured by HORSCH with great care. However, damage can also occur when used for the purpose it is intended for. ¾ Damage caused by external influences. ¾ Inappropriate or incorrectly adapted rotary, working and travel speeds. ¾ Inappropriate or incorrect attachment or setting of the implement. ¾ Failure to comply with the operating instructions. ¾ No or inadequate care and maintenance. ¾ Missing, worn or broken cultivation tools. You should therefore check the correct function and setting of the machine before each use. Compensation claims for damages which have not been caused by the machine, are excluded. This also includes that any liability for consequential damages caused by travel and operating faults, is excluded. The machine is intended for normal use in soil cultivation in agricultural applications. Any other use or use beyond these limits is considered unintended. HORSCH will not assume liability whatsoever fro damage resulting from unintended use. The risk will be borne solely by the user. The respective accident prevention regulations and other generally recognised safety-related, occupational medical and road traffic regulations are to be adhered to. 5

12 In these operating instructions The operating instructions distinguish between three different types of warning and safety instructions. The following graphic symbols are used: important instructions. if there is a risk of injury! if there is a risk to life and limb! It is important that all the safety instructions contained in these operating instructions and all the warning signs on the machine are read thoroughly Ensure that the warning signs are in a legible and replace and signs that are missing or damaged. These instructions must be followed in order to prevent accidents. Inform other users of the warnings and safety instructions. Authorised operators Only those persons who have been authorised and instructed by the operator may operate the machine. Operators must be at least 16 years of age. The operator must hold a valid driving licence. He is responsible for third parties in the operating area. The person in charge must ¾ make the operating instructions available to the operator. ¾ ensure that the operator has read and understood the operating instructions. The operating instructions are a component part of the machine. Protective clothing For operation and maintenance you need: ¾ snug fitting clothing. ¾ safety gloves and goggles to protect against dirt and sharp edged machine parts. Do not carry out any operations which may affect the safe use of the machine. 6

13 Information regarding safety The following warnings and safety instructions apply to all sections in these operating instructions. No passengers are allowed to ride on the machine! Safety symbols On the machine Read and adhere to the operating instructions before starting up the machine! Stay clear of swinging area of retractable and extendible machine parts! Switch the engine off and pull out the key before starting maintenance and repair work. It is only permitted to remain in the danger zone when the lifting cylinder safety device is applied. Watch out for fluids spraying out under high pressure, follow the operating instructions It is only permitted to remain in the danger zone if the safety support is in place 7

14 Never reach into areas where there is a risk of crushing, as long as parts could still be moving! The accumulator is charged with gas or oil pressure. Dismantle and repair only in strict compliance with the instructions in the technical manual. In order to prevent eye injuries, do not look directly at the beam area when the radar sensor is switched on! Do not climb on rotating parts. Use mounting steps provided for this purpose. Lifting hook; attach lifting tackle (chains, ropes, etc.) here when performing loading work! Retighten the wheel nuts / wheel bolts after 50 hours! 50 h / Nm

15 Grease the bearings of the intermediate axle packer and retighten the end nuts. Tiger with DuoDrill equipment: Insert the aluminium clips on the piston rods before folding. 9

16 Operational safety The machine must only be put into operation after receiving instructions by employees of the authorized dealer or a HORSCH employee. The machine registration form has to be completed and returned to HORSCH. All protective features and safety equipment, such as detachable protective devices, must be correctly in place and reliably functioning before the machine is put into operation. ¾ Check and tighten nuts and screws at regular intervals. ¾ Check tyre pressure regularly. ¾ In case of malfunctions stop and secure the machine immediately! Accident prevention In addition to the operating instructions, it is important to observe the accident prevention regulations specified by agricultural trade associations! Hitching up / unhitching There is risk of injury to persons when hitching up / unhitching the machine to the drawbar of the tractor. ¾ Secure the machine against rolling away. ¾ Take special care when reversing the tractor. Never stand between tractor and machine. ¾ Only park the machine on a firm and level surface. Before unhitching the machine, lower it to the ground. Road traffic safety The valid road traffic regulations are to be observed when travelling on public roads, paths and areas. Do not exceed the max. permissible widths and attach light system, warning and protective devices. Also observe transport height depending on the coupled machine! Do not exceed the permissible axle loads, tyre carrying capacities and total weights, in order to ensure sufficient steering and braking capabilities. Handling is affected by the implement connected. It is important to take into account the large overhang and the centrifugal mass of the implement, particularly when cornering. The whole machine is to be cleaned of soil that has been collected before travel on public roads Passengers are strictly forbidden to ride on the machine. With the Tiger 8 with double disc system pay attention: Due to the transport height the outer adjustable edge disc unit must be disassembled before transport on public roads. Travel at a maximum speed of 25 km/h for travel on public roads. 10

17 Hydraulic connections ¾ Do not connect hydraulic lines to the tractor, before both hydraulic systems (machine and tractor) are de-pressurised. ¾ The hydraulic system is under high pressure. Check all lines, hoses and screwed connections regularly for leaks and any visible external damage! ¾ Only use appropriate aids when checking for leaks. Repair any damage immediately! Oil sprays can cause injuries and fire! ¾ In the case of injury, contact a doctor immediately! Power sockets and connectors on the hydraulic connections between the tractor and machine should be colour-coded in order to exclude operating errors. The control units on the tractor must be secured or locked when not in use or when the machine is in transport position, in order to prevent accidents caused by unintended hydraulic movements or movements caused by persons other than the operator (children, passengers). Pressure accumulator Depending on the equipment of the machine, the hydraulic system may have a pressure accumulator installed. Do not open or work (welding, drilling) on the pressure accumulator. Even after being emptied, the accumulator is still preloaded by gas pressure. Changing implements ¾ Secure the machine against unintended rolling! ¾ Secure lifted frame parts, under which you will be working, with suitable supports! ¾ Caution! Danger of injury caused by protruding parts (harrow, tines, share)! ¾ Do not use packer tyres or other rotating parts when climbing onto the machine. These could start to rotate and you could fall and be seriously injured. Prior to use Prior to use check all important screwed and plugged connections, e.g. ¾ fastening of wheels and tyres; ¾ fastening of hydraulic cylinders; check the bolts, forks and clamping or locking screws for tight fit. In operation ¾ Check the area around the machine (for children!) before setting off and starting operation of the machine. Ensure sufficient visibility. ¾ Do not remove any of the mandatory and supplied protective devices. ¾ Stay clear of the operating range of hydraulically operated parts. ¾ Only use ascending aids and steps when machine is at standstill. Passengers are not allowed to ride on the machine during operation! Always depressurise the pressure accumulator before starting work on the hydraulic system. The pressure gauge should not indicate any pressure. The pressure gauge reading should drop to 0 bar. Only then may work be carried out on the hydraulic system. 11

18 Service and maintenance ¾ Ensure that regular tests and inspections are always carried out to schedule, as specified in the operating instructions. ¾ Prior to performing maintenance and servicing work, ensure that the machine is positioned on firm, level ground and that it is properly secured against rolling away. ¾ De-pressurise the hydraulic system and lower or support the implement. ¾ After cleaning, check all hydraulic lines for leaks and loose connections. ¾ Check hoses for chafing and signs of other damage. Remedy any faults immediately! ¾ Prior to working on the electrical system, disconnect it from the electric power supply. ¾ Depending on machine and Duo-Drill version: When performing welding work on the machine, disconnect the cables from computers and other electronic components. The ground connection must be as close as possible to the welding point. ¾ Retighten screwed connections which had been loosened during servicing and maintenance work. Do not wash new machines with a steam-jet or high-pressure cleaner. The paint takes approx. 3 months to cure and could thus be damaged if this time has not yet expired. 12

19 Transport / installation Higher danger of accident during initial installation. Please pay attention to the notes in the corresponding chapters. Delivery The machine with implements is normally delivered completely assembled on a low loader. If parts or modules had to be disassembled for transportation purposes, these will be assembled by our distributor or field engineer in situ. Depending on the design of the low loader the machine can be unloaded with a tractor, or needs to lifted off with suitable lifting gear (forklift truck or crane). Sufficient load bearing capacity of lifting gear and lifting tackle must therefore be assured. Lifting and lashing points are identified by labels. When using other lifting points pay careful attention to the centre of gravity and the weight distribution. These points must, in any case, only be on the frame of the machine. Installation Instruction of the operator and initial installation of the machine will be carried out by our service engineers or distributors. Any anticipating use of the machine is prohibited! The machine can only be released for operation after the instruction session conducted by our service engineer / distributor and after the operating instructions have been read. Higher danger of accident during installation and maintenance. Before performing any installation and maintenance work make yourself familiar with the machine and read the operating instructions. Depending on scope of equipment ¾ Take loosely delivered parts off the machine. ¾ Check all important screw connections! ¾ Lubricate all grease nipples! ¾ Check air pressure in tyres! ¾ Check all hydraulic connections and hoses for correct fastening and function. ¾ Immediately rectify any occurring damage or have it corrected! 13

20 Transport Depending on country specific regulations and working width the equipment can be transported on public roads, either attached to a tractor or on a trailer or low loader. ¾ The permissible dimensions and weights for transport must be complied with. ¾ The tractor must be big enough, so that sufficient steering and braking abilities are assured. ¾ If the machine is hitched up in two-point mode, the tractor link arms must be blocked against swinging sideways. ¾ For road transport the piston rods must be filled up with spacers and the machine must be lowered on these spacers. ¾ On a trailer or low loader the machine must be secured with tensioning straps or other means. ¾ Attach lifting tackle only at the specially marked points. 14

21 Design and working principle Tiger AS Tiger 6 AS with Pronto TD The HORSCH Tiger AS are characterised by their robust design and the TerraGrip tool carrier for deep cultivation down to 35 cm. The four-beam arrangement and the regular distribution of tines with a groove spacing of only 20 cm ensures blockage free passage and uniform cultivation of the complete working area. The coulters used are mainly MulchMix points without wings or wide reversible points. The narrow shape enables deep loosening and excellent mixing in of harvest residues. A trip-release system with an approx. 500 kg tripping force prevents damage to points and tines and reduces the wear on components. 15

22 Tiger MT Tiger MT The HORSCH Tiger MT are characterised by their robust design and the TerraGrip tool carrier for deep soil cultivation. With their combination of tines with large cultivation discs the Tiger MT is ideally suited for applications in fields with large amounts of even long-fibre harvest residues. The two-beam arrangement of tines and cultivation discs ensures blockage free passage and uniform cultivation of the entire working area. A trip-release system with an approx. 500 kg tripping force prevents damage to coulters and tines and reduces the wear on components. 16

23 Tiger LT Tiger LT The HORSCH Tiger LT is most suitable for deep soil cultivation on light to medium soils. With the three-beam arrangement of tines and the tine spacing of 30 cm the Tiger LT is very compact and easy to pull. The points used are mainly MulchMix without wings or wide reversible points. The narrow shape enables deep loosening and excellent mixing in of harvest residues. A trip-release system with an approx. 500 kg tripping force prevents damage to coulters and tines and reduces the wear on components. 17

24 Tiger XL Tiger XL The HORSCH Tiger XL is most suitable for stubble processing on all types of soil. The six-beam arrangement with a tine spacing of 16 cm ensures uniform cultivation and mixing of soil with harvest residues. 18

Hydraulic oil escaping under pressure can penetrate the skin and cause serious injuries. In the case of injury, consult a doctor immediately. Operation of the hydraulic system requires utmost attention. Operating errors can cause damage to man and machine. The hydraulic system is equipped with a pressure accumulator. This requires highest caution when handling, in order to avoid accidents. Do not open or work (welding, drilling) on the pressure accumulator. Even after being emptied, the accumulator is still preloaded by gas pressure. Always depressurise the pressure accumulator before starting work on the hydraulic system. The pressure gauge should not indicate any pressure. The pressure gauge reading should drop to 0 bar. Only then may work be carried out on the hydraulic system. Check the road lighting equipment at regular intervals, to prevent any other road users from being endangered by negligence! 21

31 TerraGrip Tines The TerraGrip tine is installed in Tigers AS, MT and LT. They are very robust and of simple design and most suitable for deep soil cultivation. The tines are equipped with a spring loaded trip-release system. With a trip release pressure of approx. 500 kg on each tine, this trip-release system protects tines, tine holders and points against being damaged. The tripping characteristics of the trip-release system starts with a progressive phase and thus keeps the tine in the soil over a long time. When the tripping force is reached, the degressive phase will start, allowing the tine to escape quickly and easily up to 30 cm in an upward direction. Coulter By standard the TerraGrip tines are fitted with narrow coulter points and narrow guide plates. These are suitable for deep cultivation. They break up the soil with the coulter tips and mix in harvest residues down to the cultivation depth. The coulter parts are available in a narrow and a wide design and can be combined as desired. Always support the machine with suitable means before starting any assembly or maintenance work on tines and coulters TerraGrip Tines The tines can be equipped with different point design and widths to suit various operating conditions. Maintenance: The tine is maintenance free. Only the screws on the tool carrier must be checked for tightness after the initial operating hours and before the start of the season. MulchMix Coulter 1. Narrow or wide coulter tip 2. Narrow or wide guide plate 3. Narrow or wide coulter 25

32 Goliath Tines The "Goliath" tine is installed in the Tiger XL. The tines are equipped with 5.5 cm wide coulters. Packer The continuous packer levels and compacts the soil after the tines. During work it carries the machine and in transport the centre packer serves as undercarriage. Due to the weight distribution to the packer a high consolidation and a fine crumbly, level surface is achieved. "Goliath" tine Maintenance: The tine is maintenance free. Only the screws must be checked for tightness after the initial operating hours and before the start of the season. Tyre packer with scrapers Scrapers are mounted between the tyres of the packer roller. These scrapers prevent blockage of the packer wheels and keep the spaces inbetween free of stones. Maintenance: ¾ Lubricate the bearings of the packer axles every day when in use. ¾ Check the air pressure in the packer tyres before use. ¾ Check packer and bearings for condition and tight fit. 26

33 Disc levelling In order to prevent ridge formation under all operating conditions, working depths and travel speeds, disc levellers are installed behind the tines. The discs distribute the thrown up soil and level the ground in front of the packer. Setting the depth The cultivation depth must be adjusted to the operating conditions (working depth of tines, working speed, amount and type of harvest residues) in the field. The depth of the coulter discs is set after the depth of the cultivator has been set. ¾ Open both shut-off valves and slightly raise the coulter discs. ¾ Insert the pin in the next possible position. ¾ Lower the coulter discs against the stop and check the levelling at working speed. ¾ If necessary repeat the adjustment, until the best result is achieved. With the shut-off valves the coulter discs can be fixed in position. If the valves stay open the coulter discs will always be raised on the headland. Disc leveller (standard disc) Conversion from transport to working position Depending on the working width a certain amount of conversion work is required to change from transport to working position Tiger 3 and 4 m rigid For transportation of public roads the outer discs must be pushed in to a transport width of 3 or 4 m and secured with the bolt. Tiger 5; 6 and 8 Due to the transport height on public roads the outer discs must be fully pushed in and secured with the clamping screws. Tiger 8 with double disc system Due to the transport height the outer discs must be disassembled before transportation of public roads. The discs must be returned to working position before starting work in the field. 27

34 Maintenance: The bearings are oil filled and therefore maintenance free. Border discs The outside discs prevent the formation of a ridge at both sides of the machine. Disc leveller bearing Check the discs regularly for clearance, leaks and unrestricted rotation. Notes on servicing The mechanical seals are very sensitive if water has entered and the machine is then parked over a longer period of time. This can cause corrosion and both mechanical seal rings may stick together. The mechanical seal rings will then rotate around the O-ring and damage it. Oil would run out and the bearing would be damaged after a short while. ¾ Bearings must therefore not be cleaned with high pressure cleaning equipment. ¾Before longer periods of rest the bearing locations should be sprayed with a rust dissolver or similar. ¾ Before resuming operation the discs should be turned by hand and checked for unrestricted rotation. Border disc Setting The border discs must be matched to the working conditions. For this purpose they can be infinitely adjusted in depth and rotation angle. With respect to the working depth the discs should only run lightly on the surface. However, they should not stop, since this would cause uneven wear. The rotation angle of the discs must be adapted according to the working speed and the piled up amount of soil and residue. Tiger 3 MT The border discs must be folded down from transport to working position before work is started. Before transportation on public roads they must be folded up again to maintain the transport width. Maintenance The border disc bearings are maintenance free. The service notes for disc levelling must be observed. 28

35 Cultivation discs Tiger MT The cultivation discs in the Tiger MT are installed in two rows in front of the cultivator tines. The large serrated discs cut large quantities of harvest residues and are even able to cope with long-fibre residues, such as maize straw. The preparing work by the coulter discs ensures blockage free working of the tines and uniform mixing in of residues. Support wheels The Tigers are equipped with support wheels as required for the working width. The support wheels keep the machine steady and maintain the working depth in the ground. The wheels only have a sensing and supporting function. They are not designed as load bearing transport wheels. The wheels should not lift up the side wings. Cultivation discs Tiger MT Maintenance The coulter disc bearings are maintenance free. The bearing clearance must be checked regularly and can be adjusted, if necessary. Support wheel The setting is made after the depth setting has been completed. When starting work the support wheel is raised or only the lower bolt is removed. Lower the disc harrow into the soil and adjust the support wheels when the working depth is reached. The depth stop is set by the lower bolt. The upper bolt serves as stop, so that the wheel is lifted at the headland. Setting: ¾ Raise the support wheel and pull out the adjustment bolt. ¾ Lower the support wheel to the ground. ¾ Insert the bolt into the next higher bore and lock it. ¾ Check the setting again after travelling for a few meters. 29

36 Setting/Operation Hitching up / unhitching the machine Nobody is to remain between the tractor and the machine when hitching up. Hitching-up: ¾ Depending on the design of the machine hitch it to the two-point swivel joint, the drawbar or the ball-joint coupling on the tractor. ¾ Connect hydraulic lines. ¾ Connect the road lighting equipment plug and check the function. ¾Lift the machine. ¾ Remove the support and insert it into the transport safeguard. ¾ Fold the side sections in. ¾ With Tiger 4: Fold the road lighting equipment to transport position. ¾ Insert aluminium clips on the undercarriage cylinders and, in case of drawbar hitching, on the front lift cylinder and lower the machine on these clips. ¾ Lock or secure the control units. In case of hitching by drawbar the hydraulic lines may need to be connected first to correct the height of the drawbar. Parking: ¾ Only park the machine on a firm and level surface. ¾ With Tiger 4: Plug the road lighting equipment over to working position. ¾Unfold the machine. ¾ Rest the machine on the support. ¾Remove aluminium clips from the undercarriage cylinders and, in case of swinging drawbar hitching, from the front lift cylinder and lower the machine to the ground. ¾ Relieve the hydraulic system and disconnect the hydraulic couplings. ¾Pull of the road lighting equipment plug. ¾Disconnect the towing connection. In unfolded position the weight is distributed to all packer wheels and the machine rests more safely on uneven or soft ground. This also saves the tyres and prevents damage caused by standing over longer periods of rest. In folded position the machine must only be parked on a firm and level surface. For this purpose it must be lowered as low as possible and onto the aluminium clips. If the machine is lowered onto the coulters on hard ground, the tips could break off. Do not transport the machine in a position higher than necessary. With the Tiger 6 and 8 pay special attention to the transportation height when passing under bridges and low suspended power lines. In transport position the control unit must not be switched to floating position. The packers could otherwise swing out beyond the transport width and cause damage or accidents. 30

37 Connecting the hydraulic system Connect the hydraulic system only after it has been depressurized on machine and implement side. When operating hydraulic components, slow down the control unit before the machine components reach the limit stop. Folding The folding hydraulics must be connected to a double-acting control unit. Perform folding movements only with a fully raised machine and on level and firm ground! Remove any picked up soil from all folding points. Soil can disturb the function and cause damage to the mechanics. Danger of tipping over: Keep an eye on the side wings when performing folding movements. These must move evenly. Fold and unfold only on level ground or transverse to a slope with the control unit fully opened Folding: Tiger 4 ¾Lift the machine; ¾ Tiger with DuoDrill equipment: Secure the packer roller in lowest position with aluminium clips (see "Folding Tiger 4 with DuoDrill"). ¾ Operate the control unit "Wings" and fold the wings. ¾ Insert aluminium clips into the undercarriage lift cylinders to transport support. ¾ Turn the road lighting equipment to road travel position. ¾ With optional equipment TopRing Packer: shut the valve on the valve block. ¾Lower the machine to the aluminium clips. ¾Block or interlock the control unit. Folding Tiger with DuoDrill: If the Tiger 4 is equipped with a DuoDrill drill unit the packers must be fixed in lowest position before folding, to protect the drill unit against being damaged. ¾Lift the machine; ¾ Fill up the piston rods on all packers with 100 aluminium clips each. If both wings do not reach their end stop at the same time when folding, operate the control unit again and fold the wing up to end position. 31

38 Unfolding: Tiger 4 ¾Lift the machine; ¾Turn both road lighting equipment carriers. ¾ With intermediate ring packer: open the valve on the valve block. ¾ Remove the aluminium clips for transport safeguard from the lift cylinder. ¾ Remove the safety catch bolt and insert it into the transport safeguard. ¾ Operate the "Wing" control unit and unfold the side wings speedily to the end stop. Folding: Tiger 5, 6 and 8 ¾Lift the machine; ¾Close both valves for the disc levellers. ¾ Slide in the outer disc levellers. ¾ Equipment Tiger 5, 6 and 8 with DuoDrill: insert one 50 mm aluminium clip each at the lift cylinders for the side parts on both sides (see "Folding with DuoDrill"). ¾ Operate the control unit "Wings" and fold the wings. ¾ Insert aluminium clips into the undercarriage lift cylinders for transport support. ¾ Version with hydraulic drawbar: insert aluminium clips at the front lift cylinder. ¾ Version with TopRing packer: switch the valve on the valve block over. ¾ Switch the front valve to transport position - CAUTION! The machine may lower. ¾ Lower the machine to transport height and operate the control unit "Lower", until the side packers have been fully retracted. ¾Block or interlock the control unit. Road lighting equipment carrier with shut-off valve 32

39 Folding Tiger 5, 6 and 8 with DuoDrill: With the cultivator is equipped with a DuoDrill drill unit, an aluminium clip with a thickness of 50 mm must be added to the hydraulic cylinders before folding. Unfolding: Tiger 5, 6 and 8 ¾Lift the machine; ¾ With TopRing Packer: open the valve of the packer hydraulics. ¾ Remove the aluminium clips for transport safeguard from the lift cylinders. ¾ Switch the front valve to working position. - CAUTION! The machine may lower. ¾If necessary raise the machine once again. ¾ Operate the "Wing" control unit and unfold the side wings to the end stop. ¾Switch the control unit to float position. ¾ Open the valves for the disc levellers. Sticker "Attention: Insert clip before folding" The aluminium clip prevents collision between packer and DuoDrill facility. Tiger with DuoDrill 33

40 Depth setting The working depth at the rear is determined by the aluminium clips on the hydraulic cylinders of the packer. The machine is then levelled at the front by the tractor link arms or the drawbar. Setting the working depth Basic setting ¾ Park the Tiger on level ground. ¾ Fill the rear piston rods with aluminium clips of identical quantity and colour combination. Depth setting table: Depth setting Working depth cm Distance height mm Colour combination blue 7 mm red 10 mm yellow 19 mm black 30 mm silver 50 mm Aluminium clips on packer cylinder Depth setting: From the basic settings the aluminium clips must be removed to achieve the working depth. The ratio for this is approx. 1:4, i.e.: If a clip of 1 cm thickness is removed/added, the working depth will change by 4 cm deeper or higher). For a working depth of 20 cm you must take out clips of approx. 5 cm thickness. 34

41 Front depth setting: The front depth setting via tractor link arms or drawbar is made in the field. Lifting out at the headland With smaller working depths the Tiger is only lifted out at the rear. With deeper depth settings the machine must also be lifted out at the front. If the Tiger is operated with regulating hydraulics on the tractor link arm, the lowest regulating height must be limited just below the normal working depth, as otherwise the regulating hydraulics would lower the front when lifting out. Heavy soils: In case of heavy soils and when the cultivator tends to tumble, the working depth may be adjusted up to 10 cm deeper at the rear than at the front. Drawbar For this purpose lower the cultivator to working height while driving, until the working depth is reached and the cultivator is in level position. On versions with two-point swivel joint set the tractor link arms to control hydraulics. On versions with swinging drawbar fill the piston rods of the front hydraulic cylinders with aluminium clips. If the regulating height cannot be limited, the regulating hydraulics must be switched off at the headland, or the lower link arms must be raised. During use lower the Tiger so that the cultivation discs are fully extended, then switch to float position. The working depth must be checked before starting work and, when culivating large areas, also in-between. 35

42 Additional equipment TopRing Packer The heavy cast-iron stars of the TopRing Packer crush the clods between the packer wheels. The intermediate axle packer is hydraulically pressed down for efficient performance. If the intermediate ring packer is not required, it can be blocked in transport position with the shut-off valve. The packer pressure control valve is set to 40 bar and must not be de-adjusted. In case of a broken seal the warranty will become invalid. Maintenance: ¾ Check the condition and tight fit of the v castiron stars. ¾ Check the shaft nuts for tight fit. ¾ Loose packer wheels will damage the shaft and the seals on the bearing. Dirt can enter and damage the bearings. ¾ Remove any dirt from between the parts before retightening the nut. ¾ Retighten the shaft nut with 1000 Nm. ¾Lubricate the packer bearing. TopRing Packer Operation: When lowering the machine hold the control unit under pressure for a short while, then switch to floating position after. This fills the pressure accumulator up to the shut-off pressure of 40 bar (see hydraulic diagram). In case of stones or unevenness of the ground the cast-iron packer is able to back away upwards against the accumulator pressure. Hydraulics TopRing Packer 36

43 Bout marker The Tigers 4 to 6 can be equipped with a bout marker. No persons are to remain within the operating range of the bout markers There are pinching or shearing points on all moving parts. When installing for the first time, the bout markers must be set to working width. The marking takes place in relation to the centre of the tractor. 4,0 m Operation When unfolding the bout markers the control unit needs to be operated, until the bout markers are fully unfolded. Then return the control unit to neutral position. Setting the bout marker disc: The effect of the bout markers can be adjusted and they must be adapted to the soil conditions. Loosen the clamping screws on the bout marker arm and rotate the shaft, until you attain the required marker depth. Maintenance: ¾Lubricate the bout marker disc. ¾ Lubricate the pivot points on the frame. 2,12 m Tiger 4 AS = 4 m Adjusting teh bout marker, e.g. Tiger 4 The setting length of the bout markers is half the machine width plus half the tine spacing, measured from the centre of the outermost tine. e.g. Tiger 4 AS 400 cm : 2 = 200 cm 200 cm + 12 cm = 212 cm Adjust the bout markers to 212 cm from the middle of the outermost tine. Tiger 4 AS / MT Tiger 5 AS / MT Tiger 6 AS / MT Tiger 6 LT Tiger 6 XL 212 cm 252 cm 312 cm 316 cm 308 cm 37

44 Rear drawbar A rear drawbar can be attached in order to pull implements, such as HORSCH Optipack AS or DD, behind the Tiger. The hook is designed for HORSCH implements. Other machines with a trailer nose weight of up to 500 kg can also be hitched up. DoubleDisc Packer (Option Tiger 3) The plate-shaped discs are bolted together with spacer discs under preload. This preload prevents soil from entering between the discs. Scrapers keep the space between the discs free of harvest residues. These are fastened in slots and can be adjusted towards the roller drum to compensate wear. Drawbar The drawbar is flanged to the rear of the main frame. Hydraulic lines are additionally routed to the rear to operate hydraulic implements. (see hydraulic diagram for the corresponding machine). Maintenance: Check the rear drawbar regularly for wear and tight fit. The wear should not exceed 3,2 mm. DoubleDisc Packer Maintenance: ¾Check packer bearings for tight fit. ¾Check packer shafts for free rotation ¾ Lubricate the packer bearings at regular intervals ¾Adjust the scrapers as necessary There is a risk of tipping over when hitching up an Optipack. When hitching up and unhitching lower the Tiger as far down as possible and do not raise the drawbar on the Optipack any higher than necessary. No machines must be hitched to the Tiger when driving on public roads. 38

45 Brake system The drill can be equipped with a hydraulic brake. This brake can be controlled hydraulically or with compressed air. Pneumatic brake This dual-line pneumatic brake controls the brake power to the master brake cylinder. The master brake cylinder directs the pressure hydraulically on to the brake cylinders on the packer roller. 1 2 Hitching-up When hitching up connect the pneumatic brake hose coupling "Brake" (yellow) first and then the pneumatic brake hose coupling "Provision" red. Release the parking brake. Unhitching When unhitching disconnect the red pneumatic brake hose coupling first and the yellow one after. The brake-air pressure is thereby applied to the brake cylinders and the machine is permanently braked. Apply the parking brake Pneumatic brake schematic End of the season If the machine is to be parked over a longer period of time, e.g. after the end of the season, the brake should be released to prevent the brake pads from sticking to the brake drum, making restarting more difficult. Secure the machine against rolling away. For functional safety of the valves, anti-freeze agent should be mixed to the compressed air (follow the operating instructions of the tractor manufacturer). This agent maintains the elasticity of the seals and reduces rust deposits in lines and reservoirs. 1. Pneumatic brake hose coupling "Brake" yellow 2. Pneumatic brake hose coupling "Provision" red 3. Pipe filter 4. Trailer brake valve 5. Air reservoir 6. Drain valve 7. Master brake cylinder 8. Disc brake cylinder As a preventive measure against damage caused by moisture, the pneumatic brake hose couplings can be covered with plastic lids or a plastic bag. Maintenance: ¾ Drain the air reservoir every day during operation. ¾ Clean the line filter as required, but at least once every year. ¾ Check brake lines and hoses for signs of damage. ¾ Check the brake pads for wear. 39

46 Hydraulic brake The hydraulic brake applies the brake force from the tractor through a hydraulic cylinder to the master brake cylinder. The master brake cylinder directs the pressure hydraulically on to the brake cylinders on the packer roller The function and state of the brake system must be checked before any road transportation. The brake system must be checked and serviced at regular intervals. Repairs must only be carried out by trained expert personnel. Maintenance: ¾ Check the brake fluid level in the container at regular intervals. ¾ Renew the brake fluid (DOT 4) every two years. ¾ Check brake lines and hoses for signs of damage. ¾ Check the brake pads for wear.

47 DuoDrill Seeder Tiger 4-8 machines can be fitted out with a DuoDrill seeder for the sowing of fine seeds like rapeseed, grass or mustard seed. Pneumatics: The hoses and components of the pneumatic system have to be securely and tightly closed. Air losses have a negative influence on the distribution. The distributor has to be regularly tested and cleaned for dust and deposits. Slide valves for a tram line control system can be added, if necessary. Fan: The hydraulic fan is powered directly by the tractor hydraulics. DuoDrill seeder The drill comprises a 300 l seed hopper, a pneumatic system with a hydraulic fan, injector feeder and a distributor tower. This auxiliary equipment is operated via DrillManager ME electronic seeder controls (see instructions for the DrillManager ME). Seed hopper: The seed hopper should always remain closed due to dust deposits. Dust results in malfunctions and unnecessary wear of the metering unit and can also result in a reduction in the amount of seed. Venturi: The seed is introduced into the air flow by the fan into the Venturi. The seed is removed from the lower cover during the calibration test. The cover must remain closed tightly for the machine to run in a technically perfect condition. The air flow created transports the seed from the Venturi to the seeding pipes. The necessary amount of air depends on the seed (type and weight) and amount of seed, working width and sowing speed. Requirements for the correct fan speed are therefore not possible and have to be determined in a field test. The air flow should not be higher than necessary. The seed should not be blown off the metering roller on the metering unit (see metering unit). It should not be too weak either so that the seed remains in the tubes and block them. There can also be a negative effect on seed distribution if the air flow is too weak. The fan speed has to be adapted to the specific application. Approx to 3000 r/min are recommended for even distribution depending on operating width and seed. The fan setting, seed transport and seed placement area also have to be regularly checked at the beginning of sowing. 41

48 The fan blade and the protective grid have to be regularly checked for deposits and cleaned. Deposits on the protective grid result in blockages in the seed tubes due to air losses. Deposits on the fan impeller result in unbalances. The bearing can become overloaded and damaged. Fan motor The return line has to be depressurised when connected to the tractor! Return pressure max. 5 bar! Rotation speed max r/min. The tractor has to be equipped with a flow control valve for speed control. The spool speed is adjusted by the amount of oil on the flow control valve in the tractor. The hydraulic pump has to deliver sufficient oil so that the fan speed does not drop even in case of a drop in the revolution speed of the tractor or if other hydraulic functions are being operated. Checks and Maintenance ¾ Observe return pressure of max. 5 bar. ¾ Regularly clean the suction air grid so as not to lower the air flow and thus prevent blockages. ¾ Clean the fan impeller of deposits so as to prevent unbalances and damages to the impeller and bearing. ¾ Tighten the tapper lock on the fan shaft (see tighten fan impeller).

49 Tightening fan impeller The tapper lock on the hydraulic motor fan drive can loosen due to fluctuations in temperature and material wear on the fan impeller. The fan impeller can move towards the drive shaft and destroy the fans. ¾ The imperial screws, type no should only be tightened to max. 6.8 Nm. ¾ The fan has to be tested for even rotation after tightening. The tapper lock should therefore be tightened after approx. 50 hours and checked once a year. The protective grid for the fan has to be removed in order to carry out this procedure. The tapper lock locates the fan and at the same time clamps itself on the drive shaft. Tapper lock Pay attention to the following when tightening the clamping screws. ¾ The fan impeller moves towards the housing in the direction of the protective grid when the screws are tightened, especially in case of initial assembly. ¾ A loose impeller therefore has to be aligned closer to the hydraulic motor. ¾ The clamping surfaces have to be free of oil and grease. ¾ The clamping screws have to be tightened absolutely evenly and in several steps. Tightening the flange on the cone should in the meantime be facilitated by applying light strokes to the flange (plastic hammer or shaft of a hammer). 43

50 Metering unit The HORSCH metering unit is composed of only few individual components and can be dismantled without tools. 8 1 Various metering rollers are available for the sowing of various seed sizes and amounts. The selection of the rollers is described in the instructions for the DrillManager. The metering rollers are divided up according to output per rotation Rollers for all types of grains and dry fertiliser Metering unit 1. Clearing plate with sealing lip 2. Housing 3. Drive motor 4.

Leakages result in incorrect seed rate. The metering housing surfaces have to be sealed when assembling the metering unit and the housing should not become tight during the screwing procedure. 44

51 The bottom section of the metering unit is closed by the Venturi. In the Venturi the seed is transported by the air flow. While calibrating, the seed is removed from the metering unit through the opening in the Venturi. The cover then has to be closed securely and tightly again. Roller change After selecting the roller from the table, this then has to be fitted into the metering unit. The seed hopper should be empty to carry out the roller change. ¾Unscrew the bearing housing cover. ¾Remove roller with drive shaft. Change roller The setting of the sealing lip and the rotation of the roller have to be checked after every roller change. Roller change with full hopper Roller change ¾Remove retaining clip and washer. ¾Remove drive shaft and insert new roller. Axial tolerance of the drive shaft in the rotor is necessary for the self-cleaning of the rotor in the metering housing. Roller change with full hopper ¾ Remove screws on the bearing housing cover and drive motor, remove bearing housing cover and motor. ¾ Remove retaining clip and washer from the drive shaft. ¾ Push the new Metering roller on to the drive shaft and by doing this the old rotor will be pushed to the side of the motor. ¾ Refit retianing washer on drive shaft, mount side cover and motor and refit. 45

52 Check sealing lip A defective sealing lip or an incorrectly mounted supporting plate results in incorrect seed rate during sowing. ¾ The sealing lip should not be ripped or damaged; replace if necessary. ¾ Insert side cover with sealing lip into metering housing. The sealing has to fit perfectly on the rotor. Roller for fine seeding The rotors for fine seeding are made up of cell wheels, spacers and the drive shaft. The metering roller is completely pre-assembled at the factory in order to prevent malfunctions during the sowing of fine seeds. Roller for fine seeding Sealing lip The holding plate for the sealing lip is asymmetrically divided. The broad side has to face the rotor for all normal and fine seeds. A new sealing lip should be installed with approx. 1 mm pretension. ¾ For this purpose remove the roller and the motor with cover. ¾ Assemble the side cover with new sealing lip, tighten the sealing lip only so far, that it is still moveable. ¾ Move the lip so that it projects approx. 1 mm into the roller recess. ¾ Take off the side cover, do not move the lip while doing this and tighten the bracket. ¾ Assemble the side cover, check the adjustment once again and reassemble the roller with the motor. Roller for fine seeding The rotors can be mounted with either one or two cell wheels. The delivery volume doubles with two cell wheels on the roller. The cell wheels are available for a delivery volume of 3.5 cm³, 5 cm³ and 10 cm³. Size cm³ Cell shape / cell size Amount Cells 3.5 semicircular, radius 4 mm cell discs, 3.5 cm³ 20 5 milled edge approx. 19 x 3 mm cell discs, 5 cm³ milled edge approx. 23 x 5 mm cell discs, 10 cm³ 24 During sowing, only the cell wheels turn in the roller, the spacers are stopped from turning stop positions on the housing 46

53 Locks that prevent against rotation have to be rotated for clearance in the housing when assembling and disassembling the rotors. The retaining clip should then be slid on. In case of correct assembly of the roller, the cell wheel between the spacers can still just about be rotated freely. The components should not rub; play should be kept to a complete minimum. The gap should be just visible when checking against the light. Function test After assembling the new roller, the roller has to be checked for rotation and function. Switch on the roller as described in the "Calibration test" section. Assembly of roller for fine seeding Assembly instructions: The cell wheels and spacers are mounted with shim washers to ensure that the seed cannot enter between the cell wheels and the spacers. Bearings are installed in the spacers. Shim washers are inserted depending on the manufacturing tolerance so that the cell wheels cannot rub against the spacers. ¾ The drive motor has to run on smoothly. No mechanical friction should be able to be heard. Seed rates become incorrect if rotations are not evenly balanced and the motor can become overloaded. ¾If possible, determine mechanical friction. ¾ Revise or renew damaged parts (grind, dress to size...). ¾ Release screws for drive motor and roller bearing on side covers and realign side covers in order to release tensions. ¾ Realign or renew drive shaft, if bent. ¾ If foreign bodies are stuck between the rotor and housing - remove the foreign bodies ¾ If dust has got in between the cell discs and spacers - disassemble the roller and clean. Roller for fine seeding After all components have been assembled, the space remaining up to the retaining clip is filled with shim washers. 47

54 Rapeseed brushes The rapeseed brushes clean the cell wheels in the roller for fine seeding. The rapeseed brushes have to be installed in the side cover and checked for function prior to the sowing of fine seeds. Metering unit with injector feeder The metering unit in machines with a normal hopper and injector feeder are equipped with a V2A cover with milled edges. Negative pressure is created on the injector nozzle during operation. Additional air is fed into the air flow through this V2A cover. Installed rapeseed brushes ¾Check rotation and mounting. ¾ Check condition and cleaning impact of brushes. ¾ Insert side cover with brushes into metering housing. ¾ The brushes have to fit perfectly on the cell wheels and rotate with the roller. Function and cleaning impact of the rapeseed brushes have to be regularly checked before the beginning of sowing and if there are large surface areas. Sticky cell wheels result in incorrect seed rates during sowing. Less seed is actually metered. Metering unit with cover for injector nozzle The setting of the injector nozzle with the cover works up to a potential maximum amount of seed. If this amount is exceeded, dynamic pressure appears on the injector nozzle. This means that seed can be blown out through the perforated plate, which results in an excess of seed of seed in the middle of the machine. These grains are visible on the surface of the field before they are covered by the packer or harrow. The side cover with the rapeseed brushes can be removed if the seed hopper is full. Sticky cell wheels can therefore be cleaned while still installed in the machine. The rapeseed brushes should be disassembled when using normal seeds. The housing bolt holes have to be filled. 48

55 In extreme cases the excess pressure can block the seed flow in the hopper and result in a seed stoppage. The function of the pneumatic system and seed placement should therefore always be checked especially if there are large amounts of seed and high working speeds. No grains should lie on the surface of the field. If grains are blown out, the working speed has to be reduced until the injector system works correctly again. Servicing of the metering unit The metering unit requires no specific servicing. The metering unit and the drive motor should be cleaned after the season and checked for function in order to prevent repair-related down times. Particularly the bearings in the side cover and on the drive motor can be damaged and create mechanical friction due to dust. If necessary, the bearings can be replaced in due time or should be in supply. 1 2 Drive motor 1. Screws 2.

56 Service and maintenance Follow the safety instructions regarding service and maintenance. Your machine has been designed and assembled for maximum performance, economy and operator friendliness, under a wide range of operating conditions. Your machine has been tested in the factory and by your authorised dealer prior to delivery to ensure that you receive it in optimum condition. In order to maintain trouble-free operation, it is important that the service and maintenance work is always carried out at the recommended intervals. Cleaning In order to maintain readiness for use and to achieve optimum performance, always carry out cleaning and servicing work at regular intervals. Do not clean electrical components, fan or hydraulic cylinders with a highpressure cleaner or direct jet of water. The housing, screwed connections and bearings are not watertight. ¾ Clean the outside of the machine with water. Open the Venturi pipe under the metering unit so that water which has flowed in can drain away. ¾ Clean the metering roller in the metering unit with a brush. ¾ Purge the coulters, seed pipes, seed hopper, metering unit and fan with compressed air. ¾ If the machine has been operated with dry or liquid fertiliser, clean and flush the components thoroughly. Fertilisers are extremely aggressive and can cause corrosion. Maintenance intervals The maintenance intervals are determined by many different factors. For instance, not only do the different operating conditions, climatic conditions, driving and operating speeds, dust and type of soil, the seed, fertiliser and dressing used, etc., have an effect on the maintenance intervals, but the quality of the lubricating agents and care products also determines when the next service is due. The maintenance intervals stated can therefore only serve as a guide. In case of deviations from the normal operating conditions, the intervals for the relevant maintenance work must be adapted to the conditions. Preparation for storage If the machine is to be out of operation for a longer period: ¾ Park the machine under a roof, if possible. ¾ Empty the seed hopper and fertiliser tank completely. ¾ Open the emptying outlet. ¾ Disconnect the electrical control devices and store them in a dry place. ¾ Protect the machine against rust. Use only easily biodegradable oils, e.g., rape seed oil, to spray the machine. ¾ Relieve the weight on the wheels. ¾ Protect the piston rods of the hydraulic cylinders against corrosion. Do not spray plastic and rubber parts with oil or corrosion protection agent. These parts could become brittle and break. 50

57 Lubricating the machine The machine should be lubricated regularly and each time it is washed with high pressure. This ensures readiness for use and reduces repair costs and downtimes. Hygiene Lubricants and mineral oil products are not harmful to health when used in accordance with the instructions. However, longer contact with the skin, or the inhalation of vapours should be avoided. Handling of lubricants CAUTION: Protect yourself against direct contact with oils by wearing gloves or applying barrier cream. Wash any traces of oil off the skin thoroughly with warm water and soap. Do not clean your skin with benzine, diesel fuel, or other solvents. Oil is toxic. If you have swallowed oil, consult a doctor immediately. ¾ Keep lubricants away from children. ¾ Never store lubricants in open or unlabelled containers. ¾ Avoid skin contact with oil-impregnated clothing. Change soiled clothing. ¾ Do not keep oil-impregnated cleaning cloths in pockets. ¾ Dispose of oil-impregnated footwear as special waste. ¾ Flush out any oil which has splashed into the eyes with clear water and consult a doctor if necessary. ¾ Soak up spilt oil with suitable material agents and dispose of it. ¾ Never extinguish oil fires with water, use only approved and suitable extinguishing agents and wear respiratory equipment. ¾ Oil-contaminated wastes and waste oil must be disposed of in accordance with the applicable regulations.
