Safety Meaning The meaning of the safety decals is explained below. Read the operating manual and follow the instructions The plough must only be used for the first time once the operating manual has been read and understood. Do not stand between the tractor and the plough Standing between the tractor and plough increases the risk of being crushed. This is particularly relevant when coupling the plough to the tractor. Parking stand Do not stand under or near the plough unless it is properly secured. When uncoupling, use the parking stand. If the plough tips over, it can damage the plough, or cause personal injury or material damage. Risk of crushing Using the machine can reduce the surrounding space. Be aware there is a risk of crushing. Keep clear of the danger area. Retighten bolts and nuts Regularly retighten all bolts and nuts on the plough. This is especially important after the first few hours of use. Unnoticed loosening of bolts and nuts may lead to damage or injury. 6
Safety General safety information General Please read and ensure you understand the following general safety information. Specific safety information is pointed out in the relevant chapters. Read and ensure you understand the instructions Before starting to operate the plough, read the operating manual and follow the instructions. Failure to follow the instructions may damage the plough or lead to injury. Qualified personnel only The plough must not be put into use until the user has been properly trained and is familiar with the operation and safe use of the plough. Incorrect use of the plough may damage the plough or lead to injury. Check for technical defects Before starting to use the plough, check that the machine is in perfect working condition. If there are any defective components, contact your dealer to have them replaced. Defective components may cause malfunctions, and damage the plough or lead to injury. Keep your distance Do not stand on, under or near the plough when it is operating or being coupled to the tractor. This may result in damage or injury. Support the plough Do not stand under or near the plough unless it is properly supported. If the plough tips, it may damage the plough or lead to injury. Lower the plough Always lower the plough when parking the tractor. Otherwise, the plough may lower itself and damage the plough or lead to injury. Use the front weights Fit the tractor with enough front weights to ensure stability and secure steering. Check the vicinity Always check the immediate vicinity before starting to move or operate the plough. No persons must stand close to the plough when it is being operated. Use the parking stand Use the parking stand when parking the plough. If the plough is not correctly supported, it may tip over. This may damage the plough or lead to injury. No riding on the plough Do not allow anyone to ride on the plough when in use. This may result in damage or injury. 7
Safety Coupling Risk of injury when coupling There is an increased risk of injury when the plough is coupled to the tractor. Therefore: Secure the tractor to prevent it from rolling. Do not stand between the tractor and plough when coupling Lift and lower the plough slowly Relieving the oil pressure - Unintended movements Relieve the oil pressure in both the tractor's hydraulic system and the plough's hydraulic system before connecting and disconnecting the hydraulic hoses. Otherwise, pressurised oil may cause the plough to move unexpectedly. This may damage the plough or lead to injury. Check the length of the hose Check the length of the hose on the plough and between the plough and tractor for sufficient slack. If the hoses are taut or stretched, the hoses may be damaged or destroyed. Ensure the hydraulic connections are correctly connected. Make sure you do not cross hydraulic connections when coupling them to the tractor. If the connections are crossed, it will cause the plough to move unexpectedly. This may damage the plough or lead to injury. Adjusting and maintaining Avoid skin contact with oils and lubricants When handling oils or lubricants, prevent them coming into contact with the skin by using oil resistant gloves. Oils and lubricants can damage the skin. Relieve the oil pressure - jet streams Before replacing or otherwise working with parts of the hydraulic system, relieve the oil pressure in the system. The oil pressure can be very high. Jet streams caused by high oil pressure may lead to injury. In case of injury, seek medical attention immediately. Carry out maintenance at regular intervals Carry out maintenance on the plough at regular intervals and as prescribed in»maintenance and care«. Also replace worn parts as prescribed. Ploughs that are not well maintained can malfunction. This may damage the plough or lead to injury. Do not weld Never carry out welding work on any part of the plough. The plough is made of hardened steel, and any welding will adversely affect the plough s strength. Welding may irreparably damage the plough. Retighten bolts and nuts Regularly retighten all bolts and nuts on the plough. This is especially important after the first few hours of use. Unnoticed loosening of bolts and nuts may lead to damage or injury.»tighten bolts and nuts«maintenance intervals, page 44 8
Safety Replace the drag axle after 1000 km On large mounted ploughs we recommend that you replace the drag axle after 1000 km of road transport. Road transport causes imperceptible damage to the drag axle. Use protective clothing Use protective clothing, e.g. gloves, when working with sharp parts of the plough. Parts that come into contact with the soil can be very sharp. Failure to handle these carefully may lead to injury. Use original spare parts Use only genuine Kverneland spare parts. Other products may adversely affect the correct operation of the plough and safety. The warranty will no longer be valid if parts not produced by Kverneland are used. Check the tyre pressure Regularly check to ensure the tyre pressure meets the requirements. Pressures which are too high or low may cause damage and excessive wear of the tyre.»tyre pressure«, page 14. Driving on the road Hydraulics During road transport, the taps for the hydraulic control system must be locked. Be aware of the plough s length The plough is long, and swings out when turning. In tight turns, avoid swinging the rear of the plough into obstacles. Stabilise the drawbars During all non-ploughing operations, e.g. transport, the tractor's drawbars must be secured. This will prevent the plough from accidentally moving sideways. Obey local rules Obey the local rules when driving with the plough on public roads. For example have all necessary lights installed and warning signs displayed. do not exceed the maximum permitted weights, loads and dimensions. The user is responsible for ensuring that the plough complies with the law when driving on public roads. Adapt your speed: max 25 km/h Your driving speed must be adapted to the road conditions under all circumstances, but must never exceed 25 km/h. Excessively high speeds cause excessive forces on the tractor, plough and transport wheel. This may lead to breakage or other damage. 9
Getting to know the plough Getting to know the plough This chapter provides information on the plough. You can learn about correct use of the plough and its features as well as technical information. Proper use Features This plough is intended to be used for ploughing. Any other use of the plough, e.g. as for lifting or pulling operations, is deemed improper use. The manufacturer and dealer are not liable for damage caused by improper use. Auto-reset beam The AB plough is equipped with Kverneland s automatic stone release system. The single spring leaf system releases the plough bodies over stones and other solid objects in the ground smoothly and efficiently. This means that sudden jolts and possible damage are avoided. Once the plough has passed the obstacle, the body automatically reverts to the correct plough depth. Variable working width The parallel construction on this plough allows you to continuously vary the working width using the hydraulics. This ensures an optimum combination of tractor, plough and soil consistency. Complete range of bodies A complete range of plough bodies is available for all requirements. Kverneland plough bodies offer excellent ploughing quality, are wear resistant and have a low draft requirement. Complete range of optional equipment Optional equipment on the plough consists of a wide range of depth wheels, skimming equipment, disc coulters and knives. These will meet your requirements in terms of soil type and field conditions. Wearing parts All soil engaging parts have undergone a process of heat treatment. This makes them extremely wear resistant, yet flexible enough to withstand shocks. 10

Optional equipment Optional equipment This section gives an overview of the optional equipment for the AB/ AD plough. Limitations apply. Please contact your Kverneland dealer for more information Skimmer Recommended for effective ploughing down of grass and stubble. Two types of skimmer are available: manure skimmers and maize skimmers. Both can be equipped with either a long share for more effective burial of plant waste or a short share for working deeper with the skimmer. Available with skimmer extensions. Trashboard Particularly useful when large quantities of plant waste (manure, straw, etc.) are present. Using a trashboard gives more free space between the bodies, compared to using a skimmer. Disc coulter Disc coulters are available in sizes of 45 and 50 cm (18 and 20 inches) in diameter, plain or notched. They are mounted on single arms and are easy to adjust to suit all conditions. Share knife An alternative to disc coulters, when a reduction in weight may be necessary or when blockage from trash or stones is likely. Can only be used on ploughs fitted with reversible points. 16
Optional equipment Landside knife Can be used together with all types of shares. An alternative to disc coulters, when a reduction in weight may be necessary or when blockage from trash or stones is likely. Good in combination with skimmers, and suitable for use with all types of shares. Eco-share A share for working 10cm deeper than the plough's normal share and breaking up the topsoil. This cannot be fitted to all bodies. Also an alternative for ploughing up to 10 cm shallower. Share with reversible point An effective share system for ploughing hard and abrasive soil and for use under generally difficult conditions. Share with flush fit point For ploughing in sticky soil conditions. The point is fixed by means of a single bolt and is therefore easy to replace. 17
Optional equipment Quick-fit share Reduces the downtime when replacing the points. Can be fitted to all plough bodies. Very good ground penetration. Furrow splitter Designed for mounting to any part of the mouldboard, to cut through firm soil, making subsequent operations easier. The splitter is secured with a screw in the existing hole in the mouldboard. Mouldboard extension Mouldboard extensions can be fitted for better packing of the heaps in firm soil and uphill. Furrow opener For use on the rear body to increase the width of the furrow bottom, in order to accept tractors with wider tyres. 18
Optional equipment Wear plate Can be fitted on the landsides, to reduce wearing of the landsides. Fitted to the rear end of the landside as a usable wearing part. Depth wheel It is highly recommended that a depth wheel is used on all ploughs. A wide range of depth wheels is available for the plough. Steel or rubber depth wheel A robust steel or rubber depth wheel. 19
Preparing for operation Preparing for operation This chapter will guide you through the preparations that must be made on the plough and tractor before you start operating the plough. Tractor Hydraulic connections The following chart shows the connections required on the tractor. Hydraulic functions Single-acting Double-acting Hydraulic furrow width 1 Hydraulic first furrow width [+] 1 Depth control We recommend that the tractor's depth control be initially set according to the following table. The exact settings are determined by the soil and field conditions. Plough size Depth control of the plough Initial settings Draft power regulated depth control Position control <------------> Draft control 2-5 furrows ---------X------------------------------------- Wheel distance 0-10 cm wider than the rear The tractor's inner wheel distance with which the plough can be used is from 110-160 cm. The distance between the front wheels must be 0 to 10 cm wider. 110-160 cm Tip! Take the wheel distance into account when ordering the plough so that the slide can be fitted correctly. 20
Preparing for operation Front weights Remove paint > Add sufficient front end weights to ensure safe driving. > Remove paint from all surfaces in contact with the ground. Use a scraper and paint remover. Tower A The tower (A, fig.1) must always be fitted vertically, as viewed from the front. Use the turnbuckle (B) to ensure the correct setting. It is best to use the turnbuckle (B) when extending the tractor's centre line. This ensures the least possible fluctuation of the ploughing depth of the rear body when the furrow width is being regulated B During ploughing, it is best to use the top linkage for extending the tractor's centre line correctly behind the tower on the plough. This means that distance D (1) is always a little smaller than D (2) because the tractor is aslant with the right wheel in the furrow. This can be adjusted in 3 different ways: 90º Swap over the top linkage ball and spacer (C, fig. 2). NB! Bolt F in triangle G must always be directly above the ball in the top linkage to ensure there is no unnecessary tension in the tower. This is particularly important on large ploughs. This means it is important to rotate triangle fitting G. Fit stop clips on the other side of the tower (D, fig. 2) Fit the locking piece for the tower in the other hole (E, fig. 2) D (1) G D (2) This must be adjusted when the plough is ploughing at the widest working width C F D E 21
Preparing for operation Automatic beam with stone release system. F 1 1 2 3 4 5 5 The illustration shows the composition of the HD spring. In heavy soil, two of spring leaf no. 5 can be added. Our standard spring does not contain spring leaf no. 5 In light soil, it is recommended to remove one spring leaf no. 1 from the standard spring. 4 E=70 cm B D Bolt (D) must be undone before the spring is adjusted with screw (B). The spring must be adjusted (B) so that distance E=70 cm. This measurement is marked on the long key If the depth of the plough bodies is not in a straight line when one passes underneath, this can be adjusted slightly using the eccentric between the beam and the bolt (F). Before adjustment, the spring pressure must be released and bolt (F) undone so that the eccentric casing can be turned with the key to a new position. F 22
Coupling Coupling This chapter explains how to couple the plough to the tractor. Safety Risk of injury when coupling There is an increased risk of injury when the plough is coupled to the tractor. Therefore: Secure the tractor to prevent it from rolling. Apply the handbrake. Do not stand between the tractor and plough when coupling Lift and lower the plough slowly Check the length of the hose Check the length of the hose between the plough and tractor for sufficient slack. If the hoses are taut or stretched, the hoses may be damaged or pulled out. Coupling To couple the plough to the tractor Connect the draw arms of the tractor to the drag axle on the plough Connect the hydraulic hoses to the tractor. Carefully lift the plough. Fold up the parking stand Check the linkage geometry (see below) TIP! Top linkage coupling Use the slotted holes on 4-share ploughs or larger. This allows the plough to follow the field contours Use the fixed holes on 2 and 3-share ploughs. This prevents the plough from tilting up in heavy or stony soils. Make sure the top linkage inclines slightly towards the tractor from the plough. 23
Coupling Connection geometry For a stable first furrow width, the imaginary intersection of the draw arms should be 1/3 of the axle distance behind the front axle. If this is not the case, replace the drag axle with another length.»«page 13 Ensure the correct length is used for the drag axle to obtain the correct coupling geometry. Irrespective of the wheel distance on the tractor, the first furrow regulation can be adjusted without affecting the drag direction between the tractor and the plough. The first furrow is regulated manually using a turnbuckle. The turnbuckle is adjusted so that the first furrow is like the remaining furrows. Incorrect Correct 24
Transport Transport This chapter explains how to drive safely on roads. Safety Stabilise the drawbars During transport, stabilise the tractor's drawbars. This will prevent the plough from accidentally moving sideways. Adapt your speed: max 25 km/h Your driving speed must be adapted to the road and field conditions under all circumstances, but must never exceed 25 km/h. Excessively high speeds cause excessive stresses on both tractor and plough, and may cause irreparable damage. Be aware of the plough s length The plough is long, and can swing out when turning. In tight turns, avoid swinging the rear of the plough into obstacles. 25
Transport Prior to transport Prior to transport Remove soil and dirt from the plough Stabilise the lower drawbars Adjust the plough to its narrowest working width (see photo) Parking stand This illustration shows the spring-loaded parking stand when the plough is parked This illustration shows the parking stand's position during ploughing and transport. NB! Remember to push the parking stand up before ploughing, and set it down again when parking the plough. Never transport the plough with the parking stand lowered. 26
Adjusting the plough Adjusting the plough This chapter describes the plough adjustments required to obtain the desired ploughing result. Adjustments can be carried out before and during ploughing. Recommended working order We recommend you to use the following working order when adjusting the plough in the field Working depth with depth wheel and depth control Disc coulter, skimmer and trashboard Levelling of the tractor's drawbars Working width First furrow width If one function is adjusted, this will affect the others. Therefore, this adjustment must be carried out several times. Safety Use protective clothing Use protective clothing, e.g. gloves, when working with sharp parts of the plough. Parts that come into contact with the soil can be very sharp. Failure to handle these carefully may lead to injury. Working width Adjust the working-width cylinder using the tractor s hydraulic outlet TIP! The scale indicates the working width per body, in inches and centimetres 27
Adjusting the plough First furrow width Do not adjust in the raised position Do not adjust the first furrow width when the plough is raised above the ground. This may result in damage or injury. In general, the first furrow should be the same width as the other furrows. Please be aware of the following: When using wide tyres on the tractor, decrease the first furrow width to ensure a good connection with the previous furrows. On slopes, compensate for the plough s downwards drift. When using a furrow opener on the last body, make the first furrow width 13 cm smaller than the width of the other furrows. Incorrect adjustment Correct adjustment Mechanical Adjust the first furrow width using the turnbuckle, as shown. Hydraulic Adjust the first furrow cylinder using the tractor s hydraulic outlet. 28
Adjusting the plough Working depth The plough frame should always be parallel to the ground. The top linkage should be in the centre of the slot. After changing the working depth, check the levelling of the drawbars (see next paragraph) Incorrect adjustment Correct adjustment To change the ploughing depth Lift the plough carefully Adjust using the adjustment nuts Adjust the lower draw arms with the tractors three-point control Adjust the length of the tractor's drawbars to level the plough Seen from the rear, the plough beams should be at 90º to the ground. Incorrect adjustment Correct adjustment 29
Adjusting the plough Set-up A B C The figures above show a simplified set-up (simple crown) which requires minimal adjustment. With the plough set for normal ploughing, the crown is driven without any setting other than the variation of the depth (hydraulic pack and depth wheel). First pass (A): Only the three plough bodies are ploughing. The rear body ploughs at approx. 1/2 depth. Second pass (B): Driven in the opposite direction, with the tractor's left-hand wheel in the empty furrow. The front plough body is at approx. half depth and the rear is at full depth. Third pass (C): The tractor's right-hand wheel is driven in the first furrow from the second pass. The front plough body is at approx. half depth so that the crown is sufficiently high. 30
Adjusting the plough Finishing A B Time must be taken when ploughing the final furrow to ensure that the strip of field which remains is of an equal width. Figure A and B show finishing with a 5-share plough. Finishing starts when the remaining furrow width is twice the number of shares minus 1 (9 furrows for 5 shares - 11 furrows for 6 shares, etc.). The front section is ploughed at half-depth. This half furrow is ploughed with the last body on the last pass. 31
Adjusting the plough Disc coulter [+] Setting the disc coulter: 1/3 D D > 5 cm The disc coulter must cut almost 1/3 of the disc coulter's diameter. The distance between the disc coulter and the body must be at least 5 cm. In stony soils, increase this distance. All disc coulters must have the same settings The distance between the disc coulter and the landside must be between 1 and 4 cm. TIP! Use a greater distance when there is more plant waste 1-4 cm Parallel side adjustment Stem Bolt S To adjust the depth Support the disc coulter to prevent it from dropping down Loosen bolt (R) Turn the arm Retighten bolt (R) Bolt R Arm To adjust the sideways position Loosen bolt (S) Twist the stem Retighten bolt (S) 32
Adjusting the plough Skimmer [+] The skimmers are correctly adjusted when The skimmers have a working depth of approximately 3 to 5 cm. All skimmers are adjusted equally. To adjust the depth Loosen the nuts on bolt A Loosen bolt A. Adjust the skimmer to the desired position and count the markings Retighten bolt A Tighten the nuts on bolt A A Adjusting the forward position Loosen bolt (B) Adjust the skimmers to the desired position Retighten bolt B B 33
Adjusting the plough Trashboard [+] B The trashboard should be placed with the front edge close to the mouldboard, the rear edge should be adjusted according to the ploughing depth. A There are two adjusting holes in the bracket for the trashboard, one for deep ploughing and one for shallower ploughing (A). In addition, there are two grooves in the bracket for fine adjustment (B). TIP! When commissioning the new plough, it is a good idea to adjust the trashboard in the upper position to strip the paint from the plough bodies when ploughing. TIP! It may be a good idea to adjust the height of the trashboard when changing the working width. The trashboard is set from the front. It is important that the trashboard is fitted with the front edge completely lowered against the mouldboard to prevent plant waste or similar from becoming caught up. 34
Adjusting the plough To make a further adjustment when out in the field, on level ground, drive the tractor's left front and rear wheels onto a block corresponding to the depth you wish to plough and then lower the plough to the ground. Ensure that the plough and the tractor's drawbars are the same distance from the rear wheels. Seen from the rear, the angle of the plough against the ground must be 90º, which is achieved by adjusting the length of the right lift arm. Seen from the side, the plough beams and the frame must be parallel to the ground, which is achieved by adjusting the length of the top linkage. The lower rear edge of the last landside must be clear of the ground by approx.10 mm. The height of the top linkage on the plough's tower must be selected so that the top linkage is slightly forward against the tractor's attachment point. A The hole in the tower (A) is often used when ploughing with 4 or 5- share ploughs to ensure an equal depth on the plough forward and back when ploughing on hilly ground. To prevent the rear end of the plough from tipping up on stony ground, the hole in the tower must be used; this is more important the smaller the plough is. A narrow top linkage angle gives unstable depth for uneven ground resistance. A wide angle = stable depth. The distance from the inside right rear wheel to the disc coulter or share knife on the first plough body is adjusted using the turnbuckle ( B), which is parallel to the drag axle, until the same ploughing width is set for the rest of the plough. B 35
Adjusting the plough A The tractor's top linkage must now be fitted sideways in the tower on the plough. Read page 21, section on Tower and moving the top linkage to ensure it is parallel with the edge of the furrow, i.e. via the tractor's extended centre line correctly behind the tower. (If the tractor's top linkage is not symmetrical, the side increase can be adjusted by regulating with the turnbuckle (A) until this is achieved. AD model) If the tractor has resistance regulated hydraulics with the impulse generator in the top linkage fitting, the hole in the tower must be used for the plough to have automatic depth control. Most new tractors have an impulse generator in the top linkage fitting on the tractor and the hole in the tower can be used for the plough to have automatic depth control. If you drive out into the field and start ploughing, these adjustments must be carried out one by one anyway until the plough and tractor drive as required. 36
Setting the plough Ploughing Ploughing Prior to ploughing Before you start ploughing Remove oil and grease from parts which come in contact with the ground. Checks during ploughing During ploughing, check the following regularly. Soil penetration In hard and dry soil, the plough may not penetrate the soil well. To improve the penetration Replace worn parts. Worn points do not penetrate the soil well. Slip on tractor wheels (on two wheel driven tractors) To reduce slip on the tractor wheels. Set the tractor's depth control more towards the resistance regulator or do not plough so deep Use low air pressure on the rear tyres 37
Maintenance and care Maintenance and care This chapter explains how to maintain and care for the plough. Safety Use original spare parts Use only genuine Kverneland spare parts. Other products may adversely affect the correct operation of the plough and safety. The warranty will no longer be valid if parts not produced by Kverneland are used. Use protective clothing Use protective clothing, e.g. gloves, when working with sharp parts of the plough. Parts that come into contact with the soil can be very sharp. Failure to handle these carefully may lead to injury. Avoid skin contact with oils and lubricants When handling oils or lubricants, prevent them coming into contact with the skin by using oil resistant gloves. Oils and lubricants can damage the skin. Prior to maintenance Prior to maintenance of the plough Ensure that the plough is correctly secured to prevent overturning. Use additional safety devices when required. Relieve the pressure in the hydraulic system Clean the plough around the maintenance area 38
Maintenance and care Maintenance chart The following maintenance chart displays the interval of the different maintenance operations. after the first few hours of use daily before the ploughing season after the ploughing season after power cleaning yearly/after 200 ha when worn / damaged After 1000 km of transport every 6 years Check the condition of the plough X X Lubrication X X X X Replace the hydraulic hoses X X Replace wearing parts X Retighten bolts and nuts X X Check the release-system springs X Check the tyre pressure X X Corrosion protection of parts in direct contact with the soil X True the bodies X Replace the drag axle X Cleaning Thorough cleaning will give the plough a longer service life. The plough can be cleaned using pressure equipment, but attention must be paid when spraying bearings and hydraulic components. Lubricate all nipples after power cleaning. 39
Maintenance and care Lubrication Use appropriate grease Only use EP (Extreme Pressure) grease. The use of unsuitable grease will reduce the bearings' service life. Lubricate the plough Daily when ploughing. This prevents the ingress of water and dirt into the bearings and moving parts. After power cleaning Before and after the ploughing season. Lubricate all lubrication points until grease comes out of the bearing. Remove all excess grease. Excess grease attracts dust and earth. 40
Maintenance and care The illustrations below show the lubrication points (S) Lubrication points (S) S S S S S S S S 41
Maintenance and care Replace hoses Check the length of the hose Check the length of the hose on the plough for sufficient slack. Overly taut or stretched hoses can become damaged or broken. Replace the hydraulic hoses Immediately when they have become worn or defective. Every 6 years Relieve the pressure in the hydraulic system Disconnect the hoses from the tractor Remove the old hose. Fit the new hose Tighten all couplings fully Replace wearing parts Replace parts in contact with the soil and other parts when they are worn or damaged. Use only genuine Kverneland spare parts. Remove the old part. Fit the new part Remove paint from any surfaces in contact with the soil TIP Reversible point When reversible points are worn at the end, they can be reversed. 42
Maintenance and care Replacing Quickfit points Wear eye protection Wear eye protection when replacing Quick-fit points. Otherwise, there is a risk that splinters from the Quick-Fit points can cause eye damage. Removing a worn point > Place the gore tool > Knock the point out Fitting a new point > Place the new point the right way around > Use the gore tool as a buffer between the point and the hammer > Knock the point into place There must be no paint on the angled surfaces TIP! Rotating the Quick-fit points. When the Quick-fit points are approximately 50% worn, they can be moved from the body on the right-hand side to the left. This gives better penetration. Replacing Knockon points Wear eye protection Wear eye protection when replacing Knock-on points. Otherwise, there is a risk that splinters from the Knock-on points can cause eye damage. Removing a worn point > Place the gore tool > Knock the point out Fitting a new point > Place the new point the right way around > Use the gore tool as a buffer between the point and the hammer > Knock the point into place There must be no paint on the angled surfaces 43
Maintenance and care Tighten bolts and nuts General Retighten all bolts and nuts on the plough. After the first few hours of use When necessary Yearly/after 200 ha For most bolts and nuts the following table applies. Bolt diam. Tightening torque 10.9 Bolts 12.9 Bolts kpm Nm kpm Nm M12 11.5-12.5 113-122.5 14-15 137-147 M14 18.5-20 181.5-196 22-24 216-235.5 M16 28.5-31 279.5-304 34-37.5 333.5-368 M20 55.5-61 544.5-598.5 65.5-73 652-716 M24 95-105 932-1030 115.5-127 1133-1246 Check springs for correct length 70 cm The length of the springs from locking bolt to locking bolt must be 70 cm. This results in maximum spring tension. Over time, the spring adjustment can change gradually and needs to be corrected. Check the spring length every year. Adjust the length if it is shorter or longer than 70 cm. page 46 TIP! Use the long spanner to measure the length of the spring. The notches on the spanner indicate 70 cm. F TIP! Check the spring bolts (F) for wear. Replace if required. 44
Maintenance and care Align bodies New ploughs are delivered with correctly adjusted bodies. Use of the plough can gradually alter the alignment. Therefore the alignment of the bodies must be checked after every ploughing season The bodies are correctly aligned when A2 = A1 B2 = B1 A2 = B2 The maximum permitted deviation between A1 and A2 is 5 mm. When there is greater deviation, adjust the bodies with the nuts on the supports. Start with the middle bodies. Loosen the counter nut Adjust the nut until the body is in the desired position Tighten all nuts, including the counter nut Continue with the other subsequent bodies. Also make sure that left and right hand bodies are parallel. From above, take a quick look at the left and right hand supports, to check that they are parallel Adjust when necessary. 45
Possible modifications Possible modifications Spring release system Safety This paragraph explains how to Fit or remove an automatic beam Change the automatic beams spring tension Adjust the spring tension of automatic beams Support the beam Support the beam securely when removing it, by using appropriate equipment. If the beams should fall, this can result in damage to the plough or personal injury. Use a level and horizontal floor Only remove beams when the plough is parked on a level, horizontal floor. The beam may otherwise drop down. This may damage the plough or lead to injury. Fitting and removing Fit or remove an automatic beam When the beam has been dislocated after hitting an object in the ground To change the beam s release force To remove the last body for lighter pulling In other unforeseen cases A F B C To remove the beams Park the plough on a firm, level floor. Release the spring tension by undoing bolt A Undo nuts B Undo bolt C and pull out the bolt Pull out the spring bolt F, if necessary To fit the beam Fit bolt C Fit bolt F Tighten bolt A until the spring length is 70 cm. Use the long spanner. The notches on the spanner indicate 70 cm Tighten nuts B and C 46
Possible modifications Change the release force setting The release setting s release force is correct when the beams do not become loose during ploughing unless they strike an object. You can change the release force of the automatic beam by Adding or removing spring leaf no. 5 With a double set of springs Carry out the following Release the spring tension (see page 46) Change the configurations of the auto-reset beam's spring. Reapply the spring pressure (see page 46) Type of springs Release force* kn Standard 7.0 Standard + 1 leaf no. 5 8.0 Standard + 2 leaf no. 5 (for HD spring) 9.0 Standard + 3 leaf no. 5 10.0 Standard + 5 leaf no. 5 12.0 Double ( 2 x standard) 14.0 These values apply for low beams (clearance of 70 cm) Standard Heavy Duty Leaf F Leaf F No. 1 No. 1 No. 2 No. 3 No. 4 No. 2 No. 3 No. 4 No. 5 No. 4 47
Possible modifications Lifting up the plough body The rear plough body can be lifted up if you wish to plough with one less plough body. This is carried out as follows: Release the spring tension Remove the front securing bolt for the spring Lift up the beam and lock it by placing the bolt in the hole 48
Parking and storage Parking and storage Safety Parking stand Use the parking stand when parking the plough. If the plough is not correctly supported, it may overturn. This may damage the plough or lead to injury. Park on a firm, level floor Park the plough on a firm, level floor. Parking and storage Parking Use the parking stand Park the plough Disconnect the plough from the tractor Lubricate all parts that come into direct contact with the soil. Use only biodegradable oil and grease. Perform all required maintenance when storing the plough. Parking stand Ploughs with Eco-shares [+] When the plough is equipped with an eco share on the last body only Remove the share before parking Park in the normal way or alternatively Extend the parking stand by 10 cm Place a 10 cm high wooden block under the first body Park the plough When the plough is equipped with eco shares on all bodies Extend the parking stand by 10 cm Park the plough Storage The plough is equipped with plastic and rubber components, and should therefore be stored out of direct sunlight during long-term storage. This applies especially to the mouldboards on the bodies and the skimmers and wheels. 49
