3 Dear customer! We would like to thank you for the confidence you brought to us when buying this implement. The advantages of the implement will be shown, only, operated and used with due case. When handing over this implement your dealer has already instructed you with regard to operation, adjustment and maintenance. But this short introduction requires an additional detailed studying of the instruction book. Therefore read this instruction book carefully before the first use. Please pay attention to the safety instructions mentioned in this instruction book. We hope you will understand that conversion work, not being mentioned expressly in this instruction book, may only be carried out with a written agreement of the manufacturer. Ordering spare-parts When ordering spare-parts please state type and serial No. of the implement. These information will be found on the identification plate. Put down these data on the following table so that they are always available. Type of implement: No.: Please think of using genuine Lemken spare-parts, only. Spirious parts influence the function of the implement negatively, show a shorter lifetime and increase in nearly all cases the effort in maintenance. We hope you will understand that LEMKEN can not take on the guarantee for operational disadvantages and damage being caused by using spirious parts! 1

9 1 SAFETY INSTRUCTIONS Before using the machine, always check both it and the tractor for roadworthiness and operational safety! As well as the notes in these instructions the operator is advised to comply with the generally applicable safety at work regulations and those relating to use of the public highway! Do not wear loose clothing! Before starting work, familiarise yourself with all equipment and working parts as well as their functions. It is too late for this when you are working! Keep the machine clean! Couple the implement as instructed only using the stipulated fixings! Special care is required when coupling and uncoupling implements to or from the tractor! Release cables for quick-action three point linkage couplings must hang loosely and must not release themselves at the lowest point! Before starting the engine and engaging the PTO check the area around the machine (e.g. children)! Riding on the implement both during work and during transport is not allowed! Never leave the drivers seat whilst the tractor is in motion! Driving conditions, steerage and braking are affected by mounted or towed implements and ballast weighs. Therefore, ensure sufficient front end weight for steering and braking! When cornering, take into account the wide overhang and/or the centrifugal effect of the implement! Do no stand in the working area! Do not stand in the turning and swinging area of the implement! Hydraulic devices must be operated only if nobody is standing in the swinging area! Before leaving the tractor, lower the implement onto the ground, switch off the engine and remove the ignition key! Nobody must stand between the tractor and power harrow unless the tractor is secured to prevent it rolling away by the parking brake and/or by wheel chocks. Lock the track markers in transport position! Mounted implements Before mounting and dismounting implements on/from the three-point linkage, move the raise / lower control to the position at which unintentional raising or lowering cannot take place! In the case of three-point linkage mounting, ensure that the tractor balls and the mounting pins of the implement are of the same category. There is the risk of injury from pinch and shear points in the three-point linkage area! 7

10 When operating the external lift controls for the three-point linkage, do not stand between the tractor and implement! Always ensure sufficient lateral limitation for the three-point linkage of the tractor in the transport position of the implement! When driving on roads with the implement raised, the raise/lower control must be locked to prevent lowering! Attached implements Before mounting or dismounting implements on/from the three-point linkage, move the raise / lower control to the position at which accidental raising or lowering cannot take place! In the case of three-point linkage mounting, ensure that the tractor balls and the mounting pins of the implement are of the same category! There is the risk of injury from pinch and shear points in the three-point linkage area! When operating the external lift controls for the three-point linkage, do not stand between the tractor and implement! Always ensure sufficient lateral limitation for the three-point linkage of the tractor in the transport position of the implement! When driving on roads with the implement raised, the raise/lower control must be locked to prevent lowering! Trailed implements Secure implement and tractor against unintended rolling! Never exceed the maximum permissible load of the drawbar or hitch! When fitting the implement to a drawbar or hitch, ensure sufficient movement at the hitch-point. Hydraulic equipment The hydraulic pipes are under pressure! When connecting hydraulic rams, the pipes must be connected as directed! When connecting hydraulic pipes to the tractor ensure that incorrect use is a- voided. If the connections are reversed, the opposite function is carried out (e.g. raising/lowering) and there is a risk of accidents! Regularly check the hydraulic pipes and replace them in the event of damage or signs of ageing. The replacement pipes must comply with the technical specification as laid down by Lemken! Hydraulic oil escaping at high pressure can penetrate the skin and cause serious injury! Before working on any hydraulic equipment - lower all implements/attachments, release hydraulic pressure where possible and switch off the tractor engine! 8

11 Brakes Check function of brakes before each drive! The braking systems must be checked regularly! Repairwork on brakes may only be conducted by trained staff and with suitable tools! Tyres When working on the tyres make sure that the implement has been placed on the ground safely and that it is secured by chocks against unintentional rolling! Fitting tyres requires knowledge and special tools! Repairwork on tyres may only be conducted by trained staff and with suitable tools! Check air pressure regularly and adhere to the advised air pressure! Maintenance Whenever possible, only carry out work on the implement when it is lowered onto the ground and the tractor engine at rest with the ignition key removed! Always ensure safety when working on a raised machine by the use of suitable, secure supports! Regularly check all nuts and bolts, and tighten these if necessary! Dispose of oil and grease properly! In the event of welding being required on the implement ensure that, if a tractor has to be attached, its battery/alternator is disconnected! Only use genuine or approved replacement parts when repairing the implement! 9

12 2 USE OF SPRING LOADED BRAKE RAM In order to make unloading and manoeuvring possible without air pressure supply, the spring loaded brake rams (FS) and therewith the complete braking assembly have been locked out of use by means of a key bolt (KS). Before the first use, the braking assembly must be set under pressure, the nut of the key bolt (KS) loosened, the key bolt turned by 90 and finally removed. (If it is not possible to set the braking system under pressure, the nut of the spring loaded key bolt must be loosened until it is free and can be removed.) After that close the opening of the spring loaded brake ram by means of a protection cap (SC). Finally fit the key bolt into the top bore (AB) of the braking ram and secure it by means of nut and peg. Never loosen the outer tightening straps (SP) of the spring loaded brake rams (FS), as the ram is under pressure. 10

The maximum allowed air pressure is 2,9 bar. This pressure must not be exceeded. 15

18 6 ATTACHING AND DETACHING THE TERRADISC DISC CULTIVATOR 6.1 Attaching the disc cultivator - For attaching the Terradisc 9 KA-B the hydraulics of the tractor must be set to position control! - Connect the tractor lower link to the drawbar (1) and secure! - Swing stand (AS) upwards and secure! - Connect hydraulic hoses! - Connect electric cables. If available place control box with cable in the tractor cab and connect control box to the socket! - Connect braking hoses and put wheel chocks (UK) into the holders (HL) and secure. - Release the parking brake by operating the red button of the parking valve (PA). - Fold-in the lateral sections unitl the hooks (43R) and (43L) of the folding locking device (43) are engaged! Lock tractor spool valve, in order to prevent an unintentional folding-out of the lateral sections! - For transport the lock valve (AV) must be closed! ATTENTION: Never fold-in or out the lateral sections when the hollow discs are swung to the front! 16

19 6.2 Detaching the disc cultivator The disc cultivator must always be parked on level and firm ground! Set tractor hydraulics to position control before detaching the implement! Fold-out the lateral sections completely! Remove the wheel chocks out of the holders and secure! Disconnect braking hoses! Activate the parking brake by means of pressing the red button (PA) of the parking valve! Disconnect electric cables! Open lock valve (AV)! Lower the implement and disconnect the lower links from the drawbar (1)! Stop engine and move the operation lever of the spool valve several times to and fro, in order to release the hydraulic hoses! Disconnect hydraulic hoses and fit protection cap! 17

20 6.3 Transport, Centre of gravity As the centre of gravity of the folded-in Terratine 9 KA-B is very high, there is an increased danger of tipping over! Pay attention to an appropriate road behaviour. - Before folding-in for transport, the outer discs of the Terradisc 9/600 KA-B must be swung-in, so that the allowed transport height of 4 m will not be exceeded. - After that lift the disc cultivator at the rear via the hydraulic ram (24) of the trailer device. - When the Terradisc 9/600 KA-B is equipped with track markers, clamping stops (Y) must be fitted on the pisten rod. After that the Terradisc 9 KA-B will be lowered until the clamping stops prevent a further lowering. - The maximum allowed transport height of 4 m will not be exceeded. After that the lock valve (AV) must be closed. Working position, the clamp stops (Y) are fitted on the front carrier of the lighting equipment. Transport position, the clamping stops (Y) are fitted on the piston rod. - The disc cultivator will be lifted in the front via the tractor hydraulic lift, until the frame is parallel to the ground. Before each transport, it must be ensured that the hooks (43R) and (43L) are engaged and the hydraulic ram (41H) is opened completely. - The spool valve for folding and lift must be locked finally. Read and adhere to the General Safety Instructions as well as to the Instructions Mounted Implements! The Terradisc 9/600 KA-B with fitted track markers may only be transported with clamping stops fitted on the piston rod! There is a risk of tipping over in folded-in position! 18

21 7 FOLDING-IN AND OUT THE LATERAL SECTIONS 7.1 Folding-in the lateral sections ATTENTION: Never fold-in or-out the Terradisc 9 KA-B, when the hollow discs are swung to the front! For transport the lateral sections (40) must be folded-in. They may only be folded-in or-out, when the implement is mounted to the tractor. Before folding-in the outer discs (with Terradisc 9/600 KA-B) must be swungin and the disc cultivator lifted completely in front and rear. Move the spool valve into the folding-in position = 1st pressure position, in order to fold-in the lateral sections completely. The two hooks (43R) an (43L) of the folding-out locking device lock automatically. Ckeck, whether the hocks have locked completely. Lock tractor spool valve to prevent an unintentional folding-out of the lateral sections. Close lock valve (AV) of the hydraulic ram (24)! When driving on public roads the lighting equipment must be provided and connected! 19

22 7.2 Foldind-out the lateral sections Unlock the tractor spool valve and set it into the 1 st pressure position = folding-in position for a short time and then into the 2 nd pressure position = folding-out position. The folding-out locking device (43) will be unlocked automatically and the lateral sections fold-out. When the disc cultivator is equipped with outer discs, they must be swung-out again before the first use. The Terradisc 9 KA-B may only be equipped with an hydraulic folding-out locking device, when the tractor is equipped with lockable spool valves. If the tractor has no lockable spool valves, a mechanical folding-out locking device releaseable by a rope must be used. Read and adhere to the General Safety Instructions as well as to the Instructions Hydraulics! 20

23 8 ADJUSTMENTS 8.1 Height adjustment of the drawbar The drawbar (1) can be swung into two different height positions. The lower position should be chosen when a better penetration of the cultivator is required or the cultivator is fitted to a crawler. The upper position has to be chosen when there is too much tractor wheel slip. When the height position of the drawbar is changed, the strut (S) must be connected in front to the neighboured bore of the pole. Connect the support (S) to the top bore (OB) of the pole reduced front axle unloading Connect the support (S) to the lower bore (UB) of the pole inreased front axle unloading, reduced slip, increased rear axle load. 8.2 Wing shares The wing shares (6) must be fitted underneath the frog (SF) as shown in the right handed picture. The chamfered side of the wing share must point upwards. An incorrect mounting leads to share breakage. 21

24 8.3 Share position The share position of TERRADISC and TERRADISC Ü can be altered. A flat share position ensures an even seedbed depth (point (5) and wings (6) work nearly at the same depth) and reduces the traction requirement; a steep share position ensures a good penetration, even in hard and dry soils. With the TERRADISC having a shearbolt device and with the TERRADISC 9 Ü having a bolted tine carrier (DS) with double cutting shearbolt device, the tine position and thus the share position will be altered by repositioning the shearbolt (7). Hole A = flat position (especially for heavy sticky soils = easier to pull) Hole B = steep position (especially for dry and hard conditions = improved penetration) With the TERRADISC 9 K Ü with cranked tine carrier (VZ), however, the share position will be altered by slackening and by turning (180 ) the eccentric bolt (8) having first slackened shearbolt (7). Two tine positions are possible. Read and adhere to the General Safety Instructions! See section 1! Change the share angle position only with the implement lifted 2-3 cm only. Use only suitable spanners and tools. 22

25 8.4 Depth adjustment of the tines The tines should be set at a working depth of 8-10 cm; with greater soil unevenness or deep wheel marks a deeper cultivation depth may be required. After raising the implement some cm the working depth of the tines will be adjusted as follows by means of the pin adjuster (10): Placing the lower pin (11) in a deeper hole => increased working depth. Placing the lower pin (11) in an upper hole => reduced working depth. The upper pins (12) are for obtaining enough clearance between the ground and the roller, with the cultivator raised. If with raised cultivator the roller is still touching the ground or is too close to the ground, then with fully lowered cultivator the pins (12) must be placed in a lower hole above the carrier (13). When changing the working depth, the position of the depth wheels must be altered. See section

26 8.5 Working depth adjustment of the hollow discs The discs should be set at approximate half the working depth of the tines. The discs (18) are for mixing and for levelling the ridges and grooves left by the rear tines. When working too deep, new ridges and grooves will be built, and when working too shallow, the grooves and ridges left by the tines will be levelled insufficiently. An optimum depth adjustment is achieved when the following roller (14) is "filled" with soil throughout the total working width. If the roller area behind the discs is filled with more soil than in the area between the discs, the discs are working too shallow. Conversely the discs are working too deep if the roller area between the discs is filled with more soil than the area behind the discs. The working depth of the hollow discs will be adjusted by means of the pin (21). After depth adjustment of the hollow discs, an adjustment correction is not required after altering the depth of the tines, as the depth adjustment of the hollow discs is idependantly from the depth adjustment of the tines! 24

27 8.6 Rollers The Terradisc can be equipped with D400 and D540 tube bar rollers as well as with double rollers. The re-consolidation effect of the roller (14) can be influenced by setting the top link steeper or more horizontal; in doing so the tractor hydraulics must be set to "Floating position" or Mixed control (with too much slippage). Following results can be achieved: Steeply set top link => small re-consolidating effect, less steeply set top link => medium re-consolidating effect, approximately horizontal set top link => good re-consolidating effect. If the roller is sinking too deep into the soil (in light and sandy soils) and/or will not roll and the top link cannot be set still more steeply (i.e. higher at the implement or lower at the tractor), then the pressure of the roller can be reduced by setting the tractor hydraulics to "Draft control" or "Mixed control". For such soils also a roller of 540 mm diameter or double rollers instead of the standard one of 400 mm diameter is recommended. In extremely sticky soils the packer roller ZPW 500 equipped with scrapers is recommended. This roller ensures an exact depth guiding and a good reconsolidation. Read and adhere to the General Safety Instructions! See section 1! Change top link position with fully lowered cultivator, only! 25

28 8.7 Packer roller scrapers The scrapers (Z1) must be adjusted regularly. They should be positioned to the surface of the roller by the adjuster nuts (Z2) of the scraper carrier (Z3) as shown in the sketch above. If soils sticks to the roller the scrapers must be adjusted. Dried soil on the roller creates high wear and also damages the scrapers (Z1). Therefore always remove soil before continuing work. The scrapers must be adjusted as follows: The synthetic scrapers (K) must contact the roller with a little pressure. The scrapers (A) must be adjusted as close as possible to the roller, but must not touch it. The standard scrapers (S) must always be in contact with the roller. 26

29 8.8 Pressure load on the following roller By means of the discharge valve (ÜS) weight can be transmitted from the chassis to the following implement. Turning adjuster (SR) clockwise => higher pressure load Turning the adjuster (SR) anti-clockwise => lower pressure load Each pressure load ajustment can be read at the marking lines of the adjuster. The hydro accumulator (HS) ensures that the disc cultivator can adapt to the ground independently from the chassis. When the disc cultivator is lowered again after turning on headland, the spool valve must be held in this pressure position for approximately 5 seconds, so that the pre-adjusted pressure can be reached again. 8.9 Depth wheels The disc cultivators Terradisc SMARAGD 9 KA-B are equipped with depth wheels as standard. The depth wheels prevent the outer tines working too deeply. They should not be loaded with too much weight of the disc cultivator. The depth will be adjusted by means of the pin (32). After each depth adjustment the pin (32) must be secured again. 27

30 8.10 Outer discs The outer discs (25) will be bolted to the ends of the hollow disc carriers. They should not work so deep as the inner discs; their purpose is only to move the soil which has been thrown beyond the working width, into the grooves left by the outer tines. Working depth adjustment can be made by means of pins (21). Secure pin (21) after each adjustment. For transport on public roads the outer discs (25) must be swung inwards, before folding-in the lateral sections. For folding-in remove pin (27), swing outer disc (25) inwards and fit pin (27) in hole (26) and secure pin. Read and adhere to the General Safety Instructions! For the depth adjustment the disc cultivator may only be lifted a few centimeters! In the area of the parallel linkage of the hollow discs and rollers are pinch points. Adjustments may only be done with completely lowered disc cultivator! In the area of pivot points are pinch points! Ensure sufficient distance to the pivot points! 28

31 9 SHEARBOLTS Each tine (19) and disc carrier is fitted with a shearbolt (7) which will save cultivator, tines and discs against overload. Replace sheared bolt as follows: a) Raise cultivator a few cm. b) Remove all remains of the shearbolt (7). c) Swing tine and/or disc carrier back into position. d) Fit new shearbolt into hole concerned and tighten carefully. Only shearbolts according to the schedule below should be used. Otherwise there is a serious risk of damage to frame, tine or disc carrier or a premature failure may be experienced. Tine Disc carrier TERRADISC M 12x65 B=15/8.8 M 10x45 B=10/8.8 TERRADISC 9 Ü M 20x70 B=28/8.8 M 10x45 B=10/8.8 TERRADISC 9 Ü (with double cutting shear bolt device) M12x60 B=15/10.9 M 10x45 B=10/8.8 Read and adhere to the General Safety Instructions! See section 1! When changing shearbolts, use suitable tools, only! 29

32 10 TERRADISC 9 Ü WITH AUTOMATIC OVERLOAD SAFETY DEVICE The TERRADISC 9 KÜA-B cultivator is especially designed for stony soils, and the tines (19) are equipped with an automatic overload safety device with springs (35), protecting the implement from damage when an obstacle is encountered. The tines trip back upon impact and automatically return to the working position once the obstacle has been passed. The cultivator is additionally protected by means of shearbolts (7). As special equipment also hollow discs (25) with automatic overload safety device are available. Read and adhere to the General Safety Instructions! See section 1! Coil springs are under load! If a tripped tine will not swing back into its working position, the bolts may be tightened too much. Slacken the bolts concerned but note that the tine will swing back into its working position with its full power. Keep a distance from the swinging and tripping area of the tines! 30

33 11 STRAW HARROW STR 80 The straw harrow (H) will be fitted between the following roller and the hollow discs (18) and to the lower carrier (T). By means of the pin (ST) the straw harrow can be adjusted either in working depth as well as in the distance to the hollow discs (18). By means of the pins (S2) the angle of the harrow to the soil will be adjusted. The pin (S1) prevents a swinging back of the straw harrow in lifted position. For work the straw harrow must be adjusted, so that the straw will be distributed very well, but not pile up. It must be ensured, that the tines (Z) of the straw harrow do not touch the following roller. The steeper the harrow tines (Z) are positioned, the better is the crumbling. The less steep the harrow tines (Z) are positioned, the less is the danger of clogging. Straw, which will be taken along by the harrow tines, can be taken out by the rollers again. Therewith the danger of clogging will be minimised. 31

34 12 6/2 VALVE By means of the 6/2 valve one tractor spool valve can be saved. With this valve the disc cultivator can be folded-in or-out and the coulter bar lifting device (lift linkage) can be operated. 13 ELECTRICAL CONTROL VALVE The electrical control valve L8S (SB) will be operated via the control box (BX) from the tractor seat. With this valve the disc cultivator can be lifted, the coulter bar lifted, the disc cultivator and the coulter bar folded-in or out and the track markers operated. A = Disc cultivator lifting device B = Coulter bar lifting device C = Folding device D = Track marker operation E = ON, OFF F = Control light Two operation positions are possible, which can be pre-adjusted by means of the adjuster screw (S1) at the control valve. a) Operation with constant oil supply The adjuster screw (S1) must be screwed out to the stop, in order to get into the constant oil supply setting. In this position the oil is flowing back freely from the pump via the control valve from P to T into the tank. The simultaneous operation of the other uses at the tractor like fan, rear hydraulic and front hydraulic is not possible. b) Operation with constant pressure The adjuster screw (S1) must be screwed in to the stop, in order to get into the constant pressure setting. The control valve is steadily under pressure. Now each use of the Terradisc 9 KA-B and the Solitair 9 KA can be operated. The simultaneous fan drive via an additional spool valve is possible. If the LS-connection of the control valve is used, a load sensing operation with load remote is possible. 32

35 14 ATTACHING OR DETACHING THE SOLITAIR 14.1 General Instructions The Terradisc 9 KA-B disc cultivator is available with coupling parts for mounting the Lemken Solitair seed drill. The coupling parts include an upper catch hook (FO) and two supporting plates (SP) fitted to the trailer frame as shown in the sketch. With these parts it is simple to mount the Lemken Solitair to the trailer frame (11) Mounting the Solitair seed drill - Unsecure and remove the front pin (VB). - Drive carefully with the disc cultivator to the parked Solitair seed drill until the catch hook (FO) is positioned below the top link (OB) and the supporting plates (SP) are below the lower pins (AB). - Connect hydraulic hoses of the Solitair 9 KA according to section 4.2 to the connection bracket (25) of the Terradisc 9 KA-B disc cultivator. - Unlock coulter bar (12) - Lower the Solitair a little by means of the hydraulic rams of the coulter bar lifting device until the top link pin hooks into the catch hook (FO) and the pins (AB) support on the supporting plates. - Fit front pin (V) and secure by means of the spring pin. - Connect cable according to the section Lift coulter bar, remove outer stands (9) and unsecure, lift and secure again the middle stand. See instruction book of the Solitair 9 KA. 33

36 14.3 Detaching the Solitair seed drill - The Solitair seed drill must always be parked on level and firm ground. - Before detaching, the hopper must be emptied completely and the lock valve of the coulter bar lifting device opened. - Fold-out and secure coulter bar. - Lift coulter bar by means of the hydraulic rams and move the stands (9) laterally into the frame of the coulter bar up to the stop and lower and secure the middle stand. - Unlock front pin (VB) and dismount. - After that lower coulter bar and lift the Solitair 9 KA until the top link pin (OB) is a few centimeters above the catch hooks (FO). - Close lock valve. - Disconnect hydraulic hoses. - Disconnect electric cables. - Check, whether all hydraulic hoses and electric cables are disconnected. After that drive away carefully from the parked Solitair. See instruction book of the Solitair 9 KA. Read and adhere to the General Safety Instructions as well as to the Instructions Mounted Implements! The discharge valve (ÜS) is similar to an adjustable relief control valve. Before mounting or detaching the seed drill, the adjuster (SR) of the Solitair must be turned clockwise, as with a too low adjusted central coulter bar pressure, the Solitair cannot be lifted and sinks down without control. 34

37 15 HYDRAULIC LIFT LINKAGE 15.1 Attaching a seed drill The trailed Terradisc 9 KA-B disc cultivators are available with an hydraulic lift linkage (30) (category II) for attaching a seed drill with trailer.
