Indicates some injury or property damage may result if proper precautions are not taken.

Carefully read all safety messages in this manual and on your machine safety signs. Keep safety signs in good condition. Replace missing or damaged safety signs. Be sure new equipment components and repair parts include the current safety signs. Replacement safety signs are available from your John Deere dealer.

Learn how to operate the machine and how to use the controls properly. Do not let anyone operate the machine without instruction. Keep your machine in proper working condition. Unauthorized modifications to the machine may impair the function and/or safety and affect machine life.

If you do not understand any part of this manual and need assistance, contact your John Deere dealer.

Prepare for Emergencies: Keep a first aid kit and a fire extinguisher handy. Keep emergency numbers for doctors, ambulance service, hospital and fire department nearby.

Wear Protective Clothing: Wear close fitting clothing and safety equipment appropriate to the job. Operating equipment safely requires the full attention of the operator. Do not wear headphones or use a cell phone while operating the machine.

Protect Against Noise: Prolonged exposure to loud noise can cause hearing impairment or loss. Wear suitable hearing protection to prevent damage to your hearing.

Store Equipment Safely: Securely store equipment by either lowering to ground or chocking wheels to prevent movement. Do not allow children or others to play on or around equipment.

Dispose of Waste Properly: Improperly disposing of waste can threaten the environment and the ecology. Potentially harmful waste used in this equipment includes gear oil in the oil-bath bearings and fluid in the hydraulic system. Use leak proof containers when draining fluids. Do not use food or beverage containers that may mislead someone into drinking from them. Do not pour waste onto the ground, down a drain or into any water source. Obtain information about the proper way to recycle or dispose of waste from your local environmental or recycling center, or from your John Deere dealer.

Attaching the Disk to the Tractor

The disk is equipped with a heavy tongue that both flexes and swivels to accommodate the most rugged terrain including large rocks and tree stumps. This is an essential design feature; however it requires extra care when attaching the disk to a tractor.

For best results, the tractor used to pull this unit should be equipped with a swinging drawbar with a clevis end.

The following procedure is recommended.

This procedure is best carried out with the disk in the raised position and the transport lock installed over the hydraulic cylinder. Use the hitch jack to raise or lower the tongue to the level where the tongue will lay on the drawbar. Unpin the swinging drawbar and slide it to one side. Back the tractor to the approximate point where swinging the drawbar back to the center will trap the tongue in the clevis. With the tractor parked and the brake engaged, lift the tongue (2) and swing the drawbar into the center position (1).

Do not allow others to stand between the tractor and disk when moving the tractor. Do not allow someone to hold up the tongue while backing the tractor into place. Prevent serious injury or death to you or others caused by unexpected movement of the machine. Engage the parking brake and/or place transmission in PARK, shut off engine and remove key before working around hitch.

Install the drawbar pin and its retaining hardware. This may require moving the tractor forward or backward slightly. An articulated tractor or belted tractor can swing the drawbar side to side by turning the steering wheel slightly. This procedure may take more than one attempt – safety takes time.

Attach the safety chain.

If the tractor is not equipped with a swinging drawbar, it is recommended to fabricate a prop from a length of wood to hold up the tongue while the tractor is backed into place.

CAUTION:

Transporting the Disk

□ Clean both quick disconnects and tractor couplers before connecting. Shut

off the tractor engine and move the hydraulic levers back and forth to relieve pressure in the hydraulic system. Connect the hydraulics hoses to the tractor hydraulic couplers. For ease of use it is recommended the hoses be attached in the order which lowers the disk when the hydraulic lever is pushed forward and raises it when the lever is pulled back.

CAUTION: Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid

this hazard by relieving the pressure before disconnecting hydraulic or other lines. Tighten all the connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result.

□ Turn jack handle to take weight off hitch jack. Unpin jack, remove pin, swing jack up into

transport (i.e. horizontal) position and re-pin.

□ If the tractor is equipped with a swinging drawbar. Make sure the drawbar is locked in the center

position.

□ Connect warning lights to the tractor outlet and make sure they are functioning properly. Make

sure the SMV sign is installed and visible from the rear of the machine.

□ Check tire pressure and adjust if necessary.

Adjusting the Transport Levelling Control Arm

With the disk attached to the tractor, the hydraulics connected and with the transport stay removed from the hydraulic cylinder; the machine can be adjusted to transport level as in illustration A. The adjustment is carried out by turning the nut indicated in the illustration. When the disk is raised out of the ground in the transport position, there is a significant amount of pressure against this nut. Therefore, to make the adjustment easier, lower the disk to the ground to take the pressure off the nut. The nut can then be turned easily by hand or with a large adjustable wrench. To tilt the disk forward as in illustration B, turn in the

direction indicated as B. To tilt the disk back as in illustration C, turn in the direction indicated as C. It may be necessary to raise and lower the disk a number of times to attain the desired result. Once the disk is level, lock the nut in position with the second nut on the eyebolt shaft. This adjustment remains unchanged as long as there is no change in the hitch height of the tractor.

WARNING: To avoid serious injury to self or to others, do not allow anybody on or near the disk when it is being raised or lowered. In particular, if someone other than the tractor operator is making adjustments to the disk, the tractor should be switched off while the adjustments are being made and only restarted when that person is well clear of the disk.

Transporting the Disk

□ Raise the disk to its maximum height by completely

extending the hydraulic cylinder. Install the transport stay over the hydraulic cylinder rod with the plated end against the head gland of the cylinder. Install the pins provided. Switch the tractor off and move the hydraulic lever back and forth, releasing the pressure in the system and allowing the weight of the disc to be taken up by the transport stay.

Transport Safety

□ Never allow riders on the tractor or disk. Serious injury or death can result from falling in the path

of the disk while in operation or transport.

□ Observe laws and regulations while transporting disk. Never transport disk at speeds greater

than 20 mph (32 km/h). Reduce speed and exercise caution on turns, bridges, rough roads, steep grades and other adverse conditions.

□ Install all locking devices before transporting disk. Without these devices installed, the disk could

fall during transport and cause injury or death to the operator or bystanders and/or damage to the disk, tractor and property.

□ Always used safety chains to secure the disk to the tractor during transport. Provide only enough

slack in chain to permit turning. A safety chain will help control drawn equipment should it accidentally separate from the drawbar.

□ Ensure the load does not exceed the recommended specifications of the tractor. The tractor must

be heavy and powerful enough with adequate braking power for the towed load.

□ Keep the SMV emblem and side and rear reflectors clean and visible.

□ Use headlights, flashing warning lights and turn signals day and night. Follow local regulations for

equipment lighting and marking. Keep lighting and marking visible and in good working order. Replace or repair lighting or marking that has been damaged or lost.

□ Use the proper size and grade of pin to attach the disk to the tractor.

□ If the tractor is equipped with a swinging drawbar, be sure to pin it in the center position before

transporting the disk.

□ Check wheel lug nuts for tightness and ensure tires are properly inflated and free of damaging

cuts and abrasions. The failure of either of these components can cause the disk to swing uncontrollably and make it difficult to control the tractor.

□ Remove debris and loose soil from the disk before traveling on public roads. Falling debris and

soil can be a hazard to following and approaching traffic.

□ Do not tow another implement behind the disk unless proper modifications have been made and it

is permitted by local ordinances.

Operating Safety

□ Become familiar with the disk and its operation before using the unit. Read this manual carefully

and contact your dealer if you have any questions.

□ Never allow riders on the tractor or disk. Serious injury or death could result from falling in the

path of the disk while in operation or transport.

□ Be sure bystanders are clear of the disk before raising or lowering the disk. Accidental movement

of the controls or hydraulic failure could cause the disk to suddenly fall.

□ Be sure bystanders are clear of the disk before operating the disk. Before entering the tractor,

walk around the disk making sure no one is on, under or in front of the disk. Moving the disk while someone is between or in front of the gang assemblies could result in serious injuries or death.

□ Never work under a raised disk. Always lower the disk to the ground before inspecting or

servicing. Never rely on the hydraulic system to hold up the disk.

□ Use extreme caution when working around disk blades. The blades are sharp and could cut

hands, legs, etc. Wear gloves to handle disk blades or gang assemblies.

□ Do not operate close to ditches, deep bodies of water or on excessively steep slopes.

□ Before dismounting from the tractor to service or make adjustments, always

1. Lower the disk to the ground.

2. Shut the tractor off.

3. Engage the tractor’s parking brake or place transmission in park.

4. Relieve the hydraulics by moving the control back and forth.

5. Remove the key.

Unanticipated movement of the disk while working around the disk gangs could result in serious personal injury or death.

Operating the Disk

General Operating Guidelines

□ Use the recommended size tractor. Weight is as important as horsepower. Too light a tractor will

be overpowered by the plowing action of the disk and its front end will be swung to the left, requiring constant steering corrections.

□ Always raise the disk out of the ground before turning. If pulling a harrow, roller or other toolbar

behind the disk, raise the disk just clear

of the ground before turning.

□ In the field do not back-up with the disk in the fully raised position. This will prevent the disk from

overbalancing to the rear which may damage the control arms.

□ Speed, depth and soil type all determine how level the ground left behind the disk. To minimize

ridging or gouging, limit the disking speed to 4-6 mph.

□ On tractors equipped with a swinging drawbar, allow the drawbar some movement when working

in level or gently rolling fields. In severely rocky conditions, heavy clay or tree stumps allow more swing in the drawbar. In all other conditions, lock the drawbar in the center position.

□ Pulling a drag or heavy harrow behind the disk can reduce side draft and aid in levelling the soil.

Disk Adjustments

All single offset disks have a single characteristic in common. Because the front gang of disk blades are set at an angle to their direction of movement and because these blades are working in “new” ground compared to the rear disks which are working in ground already partially tilled by the front blades, a single offset disk tries to rotate clockwise as it is pulled forward through the field. To perform optimally and to reduce stress and premature wear on components, it is desirable that the machine draft in a straight line behind the tractor. As well, the concavity of the disk blades is such that in the center angle setting the blades will accomplish the most tillage with the least horsepower and minimum wear to the blades. When the disk drafts to one side (i.e. “dog tracking” or “crabbing”) the gang angles are changed and the quality of the tillage suffers. There are three types of adjustments that affect the draft of the disk.

REPOSITION THE HITCH.

This adjustment is best accomplished when the disk is not attached to the tractor. Support the bridle crossbar to which the hitch and side arm are attached with a jack and stand. Alternatively the head of the bridle mast can be chained back to the first member of the main frame. Next loosen the large fabricated bolt and the 1-1/4” bolt attaching the hitch and side arm to the bridle. Remove the 1-1/4” bolt attaching the side arm to the plates on the side of the hitch.

The hitch bar can be placed in five fixed positions. Moving the hitch towards “L” as illustrated will cause the rear of the disk to move to the left when viewed from behind. Moving towards “R” will cause the rear of the disk to move to the right when viewed from behind.

Swing the hitch to the desired position and reattach the side arm through the appropriate bolt holes in the plates on the side of the hitch. Tighten the 1-1/4” bolts to 1500 ft/lbs and the 2” fabricated bolt to 2000 ft/lbs and recheck after the next 10 hrs of use.

CHANGE THE GANG ANGLES

Changing the angle of the front and rear gangs will affect the penetration of the gangs and mixing of the soil. By changing the gang angle, the operator can adjust for different soil conditions and change draft of the disk. Too little total angle between the gangs (minimum angles – MN) may leave uncut areas and poor penetration. Too much total gang angle (maximum angle – MX) may cause the disk to side draft in hard or soft ground conditions. The maximum front gang angle may cause the gang to bulldoze so the soil will not flow through the disk blades. The ideal situation is for the front and rear gangs to have equal amounts of angle so they both plow to the same depth.

To change the angle of the front gang, loosen the bolts at positions A and remove the bolt at position B. With the disk slightly lowered into the ground, use the tractor to carefully move the disk either forward or backwards to the desired position. Reinstall bolt B and tighten all four bolts to 1500 ft/lbs. To change the angle of the rear gang, loosen the bolts at positions D, E and F and remove C.

The rear gang of the disk can also be adjusted from side to side. If the rear gang is moved to the left, it increases the amount of soil being thrown into the furrow. If the rear gang is moved to the right, it will decrease the amount of soil being thrown into the furrow. To shift the rear gang, loosen the bolts at positions C and F and remove the bolts at D and E. With the disk blades resting on the ground, moving the disk either forward or backward will cause the gang carrier to shift to the right or left as desired. Align the bolt holes, reinstall the bolts and tighten all four bolts to 1500 ft/lbs.

Increasing the angle of the rear gang relative to the front gang, may correct a condition where the front gang is causing the disk to dog track behind the tractor.

ADJUST THE LEVELING CONTROL ARM

The leveling control arm is used to transfer pressure to the rear of the disk in order to increase penetration of the rear disk blades. Pressure is increased by tightening the adjustment nut against the spring. This adjustment is easiest to make when the disk is in the raised transport position and there is no pressure on the nut. Once the desired setting is made, lock the first nut with the second nut on the eyebolt. When the disk is lowered to the operating position, take care the spring is never fully compressed. Increasing pressure against the spring will put more down pressure on the rear blades. Carrying the disk slightly with the wheels while operating will allow the disk to pivot on the wheels and result in more even blade penetration front to rear. If the disk is operated with the wheels fully raised, little or no pressure should be placed on the spring. If disking through a sharp depression or ditch, raise the disk slightly to prevent excessive pressure on the spring and levelling arm.

Increasing pressure on the rear gang can reduce dog tracking by creating a side thrust opposite to the thrust of the front gang.

Service and Maintenance Safety

□ Before servicing the disk, always:

1. Lower the disk to the ground.

2. Shut the tractor engine off.

3. Engage the tractors parking brake and/or place transmission in park.

4. Relieve the hydraulics by moving the control lever back and forth.

5. Remove the ignition key.

□ Never work under a raised disk. The disk could fall suddenly causing serious personal injury.

Never rely on the hydraulic system to hold the disk up.

□ Periodically visually inspect the entire disk. Hydraulic fluid leaks and broken, missing or faulty

parts can create a hazard. Make necessary repairs.

□ Use caution when inflating tires. Use a clip-on air chuck, extension hose with gauge, and stand to

one side away from the tire when inflating to avoid the possibility of personal injury due to blowoffs, etc. Maintain proper air pressure in the tires. Never p.s.i. displayed on the sidewall of the tire.

□ Before disconnecting any hydraulic line relieve the pressure. Escaping hydraulic oil under

pressure can have sufficient force to penetrate the skin causing serious personal injury. If injured by escaping hydraulic fluid, obtain medical treatment immediately.

□ Handle the gang assemblies with care. The disk blades are sharp and can cut or slice skin. Use

chock blocks to prevent the gang assemblies from rolling during servicing. Wear gloves when handling the disk blades or gang assemblies.

□ After working on the hydraulic cylinder or any other components of the hydraulic system, carefully

cycle the hydraulic cylinder several times to purge air from the system and check all components for leaks. Always be sure the hydraulic lines are free of air and do not leak. ORB fittings may not leak even though they are only finger tight – tighten with a wrench. Check hydraulic hoses for cuts or abrasions and replace if necessary.

□ Securely support any machine elements that must be raised for service work. Use suitable lifting

devices and support stands where required. If using chains or straps make sure they are of sufficient strength for the load and are in good repair.

□ To avoid injury wear gloves, steel-toe boots, safety glasses, hearing protection, safety helmet and

other safety equipment where warranted.

□ Understand the service procedure before doing the required work. Keep the work area clean and

dry.

exceed the manufacturer’s maximum

Lubricate the Disk

□ The following illustrations highlight those areas of the disk subject to stress and wear. Unless

indicated otherwise, these fittings should be greased daily or after every 10 hours of operation.

□ Use a pressure lubrication gun and apply a sufficient amount of No. 2 multi-purpose lithium

grease or equivalent to flush out the old grease. Wipe the grease fitting clean before greasing.

□ Grease all fittings before first use of the season and before storage at the end of the season.

Grease wheel bearings (H) sparingly

six “shots” of grease every 150

– hours.

Check the Oil-Bath Bearings

Visually check the oil-bath bearings daily. Oil-bath bearing assemblies can leak oil from three locations and attention should be paid to these areas. A - Oil can seep from between the bearing

housing and the end cap or from around the bolts that hold the end cap to the housing. This condition is caused by loose bolts or damaged gaskets. Gaskets are placed between the end cap and the housing to preload the taper bearings in the housing. The solution is to tighten the bolts (30 ft/lbs) or replace the gaskets. B – Oil can seep past the check plugs. Plugs may use a pipe thread. Remove, clean the threads, apply “pipe dope” or Teflon tape and reinstall. C – Oil may seep by the metallic duo-cone seals. This may be caused by worn seals, loose gang axles or extreme temperature fluctuations. Worn seals should be replaced immediately to prevent catastrophic bearing failure. Such a failure will ruin all the other components of the bearing. Loose gang axles can allow the bearing flanges to move outwards and thereby allow the seals to

separate. Be sure to keep gang axles tight. Because the seals are made of metal, they can expand and contract with extreme temperature fluctuations. When they contract the sealing surfaces separate and small amounts of oil can escape. This will normally occur when the disk is in storage. Putting the disk to use will normally allow the seals to reseat themselves. Check the oil and add 90W gear oil if necessary.

Adjusting the Scrapers

Adjust the scrapers as close to the disk blades as possible without touching the blades. To move a scraper first loosen equally the u-bolts (A) holding it to the scraper bar. Use a hammer to alternatively tap the top side of the u-bolts and the scraper itself in the required direction. Once in position tighten the u-bolts equally. Turn the blades occasionally while tightening the u-bolts to ensure the scraper is not contacting the disk blade. In some conditions (e.g. heavy trash or virgin ground) plugging can occur at the bearings. Removing the scrapers (B) at these locations can alleviate the problem.

Repack and Pre-Load Wheel Hub Bearings

The wheel bearing pre-load should be set periodically or more often if transported frequently. Raise the tire so it can rotate and:

1. Remove the dust cap and gasket from hub.

2. Remove cotter pin from nut and spindle.

3. While turning the tire tighten the castellated nut until there is a slight but noticeable drag on the bearing. Do not back the nut off. Place the cotter pin in the nearest hole to secure the nut. Replace the dust cap and gasket.

Repack the wheel hub bearings yearly by:

1. Remove the tire from the hub.

2. Remove the dust cap and gasket.

3. Remove the cotter pin and remove the castellated nut from the end of the spindle.

4. Slide the hub off the spindle.

5. Clean bearing cones, dust cap and nut with kerosene or other appropriate solvent.

6. Clean the inside of the hub and inspect the bearing cups and the seal. If they show excessive wear or are damaged, replace both the cups and cones and seal. Though it is not always necessary, it is advisable to replace the seal whenever repacking the hubs.

7. Pack the bearing cones and inside cavity of the hub with No. 2 multi-purpose lithium grease or equivalent. Make sure no foreign material contaminates the lubricant.

8. Place the rear bearing cone into the back of the hub and press the seal into the hub. Place a light film of grease on the seal surface and carefully slide the hub onto the spindle taking care not to damage the seal.

9. Place the outside bearing cone over the spindle and into the hub.

10. Install the castellated nut and follow the procedure for setting the pre-load.

11. Reinstall the dust cap and tire.

Check the wheel lug nuts and wheel bearing pre-load after the next week of operation.

Fluid and Fastener Specifications

□ DISK GANG ASSEMBLY AXLES: The disk gang assembly axles are 2-1/2” in diameter and are

threaded at either end. A 4” heavy cast nut is installed at either end and tightened to complete the rigid gang assembly. To insure proper functioning and maximum durability, the axle nuts should be checked and tightened daily during the first (7) seven days of operation when the disk is new or after replacing any of the gang assembly components. When installing the nut, apply an anti-seize compound to the threads.

□ OIL-BATH BEARING OIL: The oil-bath bearing contains back-to-back tapered roller bearings

operating in gear oil. The bearing has a check plug on the side of the housing. Oil is filled to the bottom of the check plug hole. Fill oil until it begins to run out the hole.

Recommended Gear Oil – SAE 90W (API GL-4)

A heavier weight of gear oil may be used in hot climates where there may be constant

temperatures in excess of 90°F.

□ TIRE AND WHEEL SERVICE

When checking wheel nut for tightness or remounting the wheel, tighten the wheel bolts in the sequence illustrated.

Torque wheel nuts to 280-300 ft/lbs.

Check the tires regularly for cuts or other damage.

Check and adjust tire pressure when tire is cold.

Maintain tire pressure at 90 psi (max 120 psi).

The torque values in table are for plated unlubricated bolts and nuts.

Keep Gang Assemblies Tight

□ To ensure proper function and maximum durability, the axle nuts should be checked and

tightened daily during the first (7) days of operation when the disk is new or after replacing any of the gang components.

□ Loose axles may bend or break or cause damage to other components of the gang assembly.

Maintaining tight gangs is necessary to ensure maximum bearing life.

□ A loose gang assembly is evident when some disk blades stop turning when disking or turn at a

different speed than other disks on the same assembly.

□ To tighten the axle without removing the gang assembly

from the disk: To minimize the possibility of thread damage, clean out the cavity between the inside of the nut and the flat milled surface at the end of the axle. After using compressed air or a pressure washer to remove as much material as possible, pour or spray a light oil or penetrating fluid into the cavity.

Unbolt and remove the nut locks from the end washers on both ends of the axle. Loosen but do not remove the bolts holding the bearings to the bearing standards. Place one wrench on an axle nut to prevent the axle from turning. Use the other wrench and an extension (i.e. 4 to 5 foot length of 2” pipe) or a sledge hammer to tighten the axle nut on the opposite end of the axle. Tighten the nut to

approximately 2000-2200 ft/lbs. Retighten the bearing bolts. If the gang is excessively loose it may be necessary to completely disassemble the entire assembly and clean the mating surfaces between the spools, bearings, end washers and disk blades.

□ If it is necessary to remove and disassemble the gang assembly, use suitable lifting devices and

supports to prevent injury.

With the disk lowered to the ground, first remove the scrapers and then unbolt the bearings from the bearing standards. There are four 1-1/4” x 5” bolts holding each gang assembly to the gang bar. Once the bolts are removed, raise the disk high enough to either roll or pull the assembly from under the disk. Block the gang to prevent it from rolling. Remove the nut locks from both ends of the assembly. Use one wrench to keep the gang from turning while using the other wrench to tighten the nut at the opposite end of the assembly.

It may not be possible to properly tighten the gang if dirt, grit or debris has built-up between the components. In this case remove a nut from one end of the axle, slide off the end washers, bearings, spools and disk blades. Thoroughly clean the mating surfaces between the components and reassemble on the disk gang (see assembly section). Clean the threads on the axle and in the axle nut. Apply an anti-seize compound to the axle threads and reinstall the nut. Tighten the nut and reinstall the nut locks. Place the assembly under the disk and bolt to the gang bar bearing standards. Occasionally turn the gang while tightening the bolts to check the gang turns freely. Retighten the bearing bolts after the first 10-12 hours of operation.

Assembly Safety

□ Wear proper attire when assembling disk. Always wear relatively tight and belted clothing to

avoid entanglement in equipment. Wear sturdy, grip work shoes and protective equipment for eyes, hands, hearing and head.

□ Handle the disk gang components with care during assembly. The disk blades are sharp and can

cut hands, feet, etc.

□ Disk blade assemblies and disk weldments and components are heavy and awkward. Two-

person assembly is recommended. When working with others, try to maintain visual contact and communicate actions and procedures which may present a danger to them.

□ Read assembly instructions thoroughly before beginning.

□ Use the proper tools and equipment for assembly. Make sure you understand the safe

procedures for the motorized equipment and lifting devices you will be using. Make sure tools and equipment are in good repair.

□ Use proper supports for the job and chock tires or any other components that could roll

inadvertently.

□ Purge air from hydraulic systems before operation. After connecting the hydraulic lines, carefully

cycle the hydraulic cylinder several times to purge air from the system. Visually check all connections for leaks.

□ Never use your hands to check for hydraulic leaks.

Assemble the Disk

□ The disk is normally shipped with the bridle and transport assemblies attached to the frame. The

gang assembles are bolted to the gang bars and the scrapers are bolted to the scraper bars. The hitch, side arm, levelling control assemblies, transports control assemblies, jack and hose holder are bundled together. Tires are shipped loose and the remaining components (hydraulics, lighting, etc) are usually crated.

□ The parts diagrams in this manual may facilitate assembly of the disk.

□ These instructions require a forklift, boomlift or similar type of equipment which is capable of lifting

the disk weldments. A minimum 8000 lb outdoor application forklift with fork extensions is a good choice. A tractor to move the disk and charge and operate the hydraulic cylinder will also be required.

□ The following tools will also be required:

1. A selection of chains and straps.

2. Box end wrench set to 1-1/4” plus 1-1/2” and 1-7/8”.

3. Socket and rachet sets to 1-1/4” plus 1-1/2” and 1-7/8”.

4. Hammers and sledge hammer.

5. Pinch bar.

6. 24” adjustable wrench.

7. Pliers and vise grips.

8. ½” and ¾” drive air wrench and sockets.

1. Run a chain or strap from the top of the bridle mast to the first frame cross member to keep the bridle from falling forward while working on the disk. A preferred method is to place the pin in the clevis at the top of the mast and the pin in the clevis on the frame cross member. It is then possible to run a light chain or a strap around the pins. This will help prevent damage to the paint. Ideally the bridle mast should be held at a 90 degree angle to the top of the frame.

2. Use a chain or strap around the frame and the leg of the transport to keep the transport from dropping when the frame is lifted ( see 3 ). If using a chain, place rubber or matting under the chain to prevent damage to the paint.

3. Lift the back of the disk high enough to mount the tires on the hubs. One method is to place the forks of a forklift under the rear cross member.

4. Install the hub spindles into the axle pipes and install retainer bolts. Mount the tires and wheels on the hubs and tighten the wheel lugs in the sequence illustrated.

5. Lower the frame to the ground and remove the chain or strap placed in step 2.

6. Attach the hydraulic cylinder to the frame at the clevis on the cross member. Remove the plugs from the cylinder ports to prevent an air lock when the rod moves in the cylinder barrel.

7. By raising and lowering the back of the frame, the transport uprights can be moved until the rod end of the cylinder can be pinned to the transport. Once the cylinder is connected, raise the rear of the disk until the wheels clear the ground. At that point the cylinder should be fully extended.

8. Place the transport stay over the cylinder and lower the disk to the ground

9. Chock the tires and place a support under the front right corner of the disk frame.

10. If necessary, adjust the chain or strap between the bridle mast and frame cross member to ensure the mast is as vertically straight as possible. This will simplify the installation of the hitch.

11. Using a forklift or other suitable lifting device, attach the hitch to the bridle with the large 2” fabricated bolt. Do not tighten the bolt at this time. The hitch will hang from the bridle unsupported.

12. Again using a forklift or other suitable lifting device, attach the sidearm to the bridle with the 1-1/4” bolt inserted up from the bottom. Do not tighten at this time. Swing the sidearm and hitch towards each other and attach the sidearm to the hitch at the second hole from the front of the side plates on the hitch. Again insert the 1-1/4” bolt up from the bottom. Tighten all three bolts.

13. Lift the hitch and remove the chain or strap between the bridle mast and frame cross member.

14. Attach the jack to the hitch and adjust it to support the tongue at approximately 22” (tractor drawbar height) from the ground. Attach the hose holder to the hitch.

15. Bolt the triangular shaped lever plate (Item 15 – page 35) into the clevis on top of the first frame cross member. Install the bottom transport control arm (Item 14 – page 35) between the clevis on the transport assembly and the lever plate. Install the top transport control arm and eyebolt (Items 7 and 8 – page 35) between the lever plate and the bridle mast. Turn the nuts on the eyebolt clockwise (facing towards the back of the disk) until the rear most nut contacts the pipe end of the transport arm.

16. Install the levelling assembly (Items 7, 9, 10 and 11 – pg 35) between the mast and the frame. There should be no pressure against the spring.

17. It is now possible to lift the hitch of the disk and remove the support from under the frame. Leave the tire chocks in place. At this point the hydraulic hoses can be connected to the cylinder but do not charge the system.

18. Place the front gang bar assembly ahead of the hitch at an approximate 20 degree angle and with the disk blades facing the direction illustrated. When the gang bar assembly is attached to the frame the blade scrapers must be to the rear.

19. Using a forklift or similar equipment, chain to the end of the hitch. Lift the hitch; unpin the jack, swivel it up and re-pin; and pulling the disk forward, lift it up and over the gang bar assembly. Drop the jack and unchain from the hitch.

20. Using a single strap or chain of sufficient strength wraped around the center balance point of the gang bar, lift straight up throught the frame. This may require fork extensions or a boomlift. Once a single bolt and nut is installed (do not tighten), the gang bar assembly may be lowered and the chain repositioned to ease installation of the remaining bolts. A pinch bar will make this task easier. Install the bolts as per illustrations

21 and 22 on page 30.

21 - 22. Note: Gang bars deleted for clarity.

23. Place the rear gang bar assembly under the rear of disk with blades facing in the direction illustrated.

24. Use a single strap or chain of sufficient strength wrapped around the gang bar at its center point of balance to lift the bar up to the frame. This may require fork extensions or a boomlift. Once a single bolt and nut is installed (do not tighten), the gang bar assembly may be lowered and the chain repositioned to ease installation of the remaining bolts. A pinch bar will make this task easier. Install the bolts as per illustrations 25 and 26 on page 31.

25 – 26. Note: Gang bars deleted for clarity.

27. Install lights on the rear gang scraper bar and within 16” of the outside extents of the disk width.

28. Install the light kit module. Run the cables between the lights and the module as per the tags on the module pigtails indicating right hand and left hand. Run the single cable from the module to the front of the disk.

Plug the light connector into the tractor receptacle and check for proper operation. Install the safety chain on the front of the hitch. Install the hose holder on hitch and clamp the hoses to the holder. If not already attached, hitch the disk to the tractor. Couple the hydraulic hoses to the tractor. Charge the hydraulic cylinder. It will be necessary to hold the hydraulic control open for a minute or two in order to completely fill the cylinder and extend the cylinder rod enough to remove the transport stay. Remove the transport stay and lift the disk up and down a number of times to purge the system of air and reveal any leaks. Replace the fluid removed from the tractor hydraulic system. Check all the safety decals are present and undamaged.

Disk Gang Assembly Procedure

A disk gang consists of an axle on which disk blades, spacer spools and bearings are mounted. The axle is threaded at each end. End washers are then placed on both ends of the axle. Heavy axle nuts are then threaded onto each end and tighted to a recommended torque of 2000-2200 ft/lbs. The axle nuts are locked into place by bolting a nut lock plate around the nut and to the end washers with bolts and lock nuts. The disk blades, spacer spools and bearings have both concave and convex surfaces. Care must be taken to match convex with concave surfaces during assembly. End washers are either concave or convex and the appropriate washer should be placed at each end of the axle.

CAUTION: Gang components are heavy. Two-person

assembly is recommended. Follow Safety Guidelines.

To assemble, install the convex end washer and nut on one end of the axle. Slide one blade concave side down the axle against the convex end washer. Next slide a bearing onto the axle, concave end first, against the disk blade. The axle can now be raised to the vertical position and it will stand without being held. In the upright position, the convex end washer should be snug against the underside of the disk blade. If necessary, tilt the axle and disk blade and place a spacer (eg. a length of 1” X 4” wood) between the nut and the floor or ground. This ensures the top threaded end of the axle will be exposed when the gang is completely stacked and the nut can be installed.

With the axle in the upright position, the remaining components can be stacked. Keep all the spacer spools between the bearings with the bearings in the outermost positions on the axle. While stacking the components, make sure all mating surfaces are free of dirt, rust, grease, grit or any other material that interferes with the mating surfaces. After the last disk is in

place, drop the concave end washer into place. Apply an anti-seize compound to the axle threads and install the axle nut. Tighten the nut to remove as much slack as possible. Lower the entire assembly to the ground using hoist or forklift and chock both sides of the assembly to prevent it from rolling. Using the gang wrenches provided with the disk, tighten both axle nuts as tight as possible. It may be necessary to use a length of 2” pipe on the wrenches for extra leverage. A sledge hammer may be used to strike the wrench handle for the final adjustment to fit the nut lock plates. Install the nut lock plates over the axle nuts and attach to the end washer with the four bolts and lock nuts provided.

Storage

At the end of the season and when putting the disc into storage:

□ Clean dirt and debris from around moving parts and from the top of the frame, gang bars, hitch

and bridle.

□ Pay special attention to cleaning the area around the bearings. Spray a light coating of oil or

rust preventative around the seal area of the bearings.

□ Lubricate all grease fittings to prevent moisture infiltration.

□ It is recommended to park with the disk in the raised position, coat the exposed hydraulic

cylinder rod with grease, install the transport stay and relieve the hydraulic pressure. Place a block under the hitch jack to prevent it from sinking into the ground and be sure the tires are properly inflated. Chock the tires front and rear.

□ Clean disk blades to minimize rust.

□ Coat the quick disconnects in grease and wrap in plastic to prevent rust.

□ Make a final inspection for worn, damaged or missing parts and make necessary repairs

before the next season.
