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.
