SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be wiped out by an operator’s single careless act.
In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in the operation, transport, maintenance and storage of equipment.
It has been said “The best safety device is an informed, careful operator.” We ask you to be that kind of operator.
Never allow children or untrained persons to operate equipment.
PREPARATION
Check that all hardware is properly installed. Always tighten to torque chart specifications unless instructed otherwise in this manual.
Always wear relatively tight and belted clothing to avoid entanglement in moving parts. Wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.
Make sure attachment is properly secured, adjusted, and in good operating condition.
TRAINING
Safety instructions are important! Read all attachment and power unit manuals; follow all safety rules and safety decal information. (Replacement manuals and safety decals are available from your dealer. To locate your nearest dealer, check the Dealer Locator at www.WoodsEquipment.com, or in the United States and Canada call 1-800-319- 6637.) Failure to follow instructions or safety rules can result in serious injury or death.
If you do not understand any part of this manual and need assistance, see your dealer.
Know your controls and how to stop engine and attachment quickly in an emergency.
Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.
Make sure driveline guard tether chains are attached to the tractor and equipment as shown in the pamphlet that accompanies the driveline. Replace if damaged or broken. Check that driveline guards rotate freely on driveline before putting equipment into service.
Power unit must be equipped with ROPS or ROPS cab and seat belt. Keep seat belt securely fastened. Falling off power unit can result in death from being run over or crushed. Keep foldable ROPS systems in “locked up” position at all times.
Remove accumulated debris from this equipment, power unit, and engine to avoid fire hazard.
Operators must be instructed in and be capable of the safe operation of the equipment, its attachments, and all controls. Do not allow anyone to operate this equipment without proper instructions.
Keep hands and body away from pressurized lines. Use paper or cardboard, not hands or other body parts to check for leaks. Wear safety goggles. Hydraulic fluid under pressure can easily penetrate skin and will cause serious injury or death.
Make sure that all operating and service personnel know that if hydraulic fluid penetrates skin, it must be surgically removed as soon as possible by a doctor familiar with this form of injury or gangrene, serious injury, or death will result. CONTACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.
Make sure all safety decals are installed. Replace if damaged. (See Safety Decals section for location.)
Make sure shields and guards are properly installed and in good condition. Replace if damaged.
A minimum 20% of tractor and equipment weight must be on the tractor front wheels when attachments are in transport position. Without this weight, tractor could tip over, causing personal injury or death. The weight may be attained with a loader, front wheel weights, ballast in tires or front tractor weights. Weigh the tractor and equipment. Do not estimate.
Inspect and clear area of stones, branches, or other hard objects that might be thrown, causing injury or damage.

Driveline Attachment
Attach the cutter to the tractor 3-point hitch (or quick hitch if available). Do not attach driveline. Raise and lower cutter to determine maximum and minimum distance between the tractor PTO shaft and the gearbox input shaft. If the distance is too large, the driveline will be too short for proper engagement. If distance is too small, the driveline may bottom out in operation and damage the cutter or tractor.
Driveline length must be sufficient to provide at least 1/3 driveline length of engagement during operation. There must be at least 4 inches of engagement at the cutters lowest possible point of operation. The driveline must not bottom out when raised to the maximum height possible.
If driveline is too short please call your Woods dealer for a longer driveline.
If driveline is too long please follow the instructions for shortening the driveline.
Shorten Driveline
1.Move cutter up and down to get the shortest possible distance between tractor PTO shaft and gearbox input shaft.
2.Separate driveline into two halves and connect them to the tractor PTO and gearbox.
3.Place driveline halves parallel to one another to determine how much to shorten the driveline.
Figure 1. Drive Halves Placed Parallel
4.Measure from end of the upper shield to the base of the bell on the lower shield (A). Add 1-9/16" to dimension (A). See Figure 2.

7.Repeat step 6 for the other half of the drive.
8.File and clean cut ends of both drive halves.
Do not use tractor if proper driveline engagement cannot be obtained through these methods.
Connect driveline to tractor PTO shaft, making sure the spring-activated locking collar slides freely and locks driveline to PTO shaft.
NOTICE
■ If attaching with quick hitch the distance between the tractor PTO and gearbox input shaft will increase. Please follow the steps as you would for a 3-point hitch to insure proper engagement.
Cutting Height Adjustment for MD80 Mounted Cutter (Figure 5)
Place tractor and cutter on a level surface.
The adjustments given here are to provide you with a starting point. Adjustments are approximate and may vary due to slight differences in blade shimming and machine wear. You may desire to fine tune them for your situation.
WARNING
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
■ Avoid very low cutting heights. Striking the ground with blades produces one of the most damaging shock loads a cutter can encounter. Allowing blades to contact ground repeatedly, will cause damage to cutter and drive.
Cutting height may be controlled by several methods. Without the optional check chains and tailwheel it is controlled with the tractor 3-point lift and top link adjustment.
Measure from front edge of cutter frame (on each side) to ground to be sure cutter is level. Use adjustment on 3-point arms, if necessary, for fine adjustment side to side.

The blade is approximately 9-1/4" below the top of the cutter deck.
Select a cutting height, EXAMPLE 3".
Use tractor 3-point lift to set front blade 3" above level surface (measure 12-1/4" from top of deck to ground). At the rear, measure from top of deck to ground; adjust top link until this distance is from 12-3/4" to 13". Adjust lower stop of the tractor 3-point lift control. When adjustment is set, this will enable you to return to the preset cutting height.
Maintain distance from blade tip to level surface from 1/2" to 3/4" higher at rear for best cutting results and lowest power consumption.
When using cutter for shredding, it is better to set blade tip lower at the rear. How much lower depends on the material to be shredded. You will need to experiment to determine the best setting for your situation.
Cutting Height Adjustment With Tailwheel or Check Chains
The blade is approximately 9-1/4" below the top of the cutter deck.
Select a cutting height, EXAMPLE 3".
Use check chains and tractor 3-point lift and raise top front of cutter deck 12-1/4" above the level surface. At the rear, measure from top of deck to ground; adjust tailwheel until this distance is from 12-3/4" to 13".
Shorten the check chains to raise front of cutter. Move tailwheel adjustment to the rear to raise rear of cutter.

ATTACHING CUTTER TO TRACTOR (PULL-TYPE MODELS)
The cutter is shipped with a 1-3/8" PTO spline. The horizontal distance between the end of the tractor PTO shaft and the drawbar hitch point should be 14". This distance must not vary more than plus or minus one inch (±1") or the drive may be damaged when turning. Adjust tractor drawbar to obtain the desired drawbar to hitch point distance. On some tractors, a drawbar kit must be used to obtain the required dimension. Check with your tractor dealer if you encounter problems.
Raise cutter tongue to tractor drawbar height with jack provided and attach with a 3/4" or larger high-strength drawbar pin. Retain pin to keep it in place.
Connect cutter driveline to tractor PTO shaft, making sure the spring-activated locking pin slides freely and is seated firmly in tractor PTO spline groove.
Adjust H-frame bearing height to ensure front driveline is parallel to ground.
Remove parking jack from tongue. Attach to frame rail storage with top forward. Always attach jack to tongue to hold it up when disconnecting it from tractor.
Adjust drive shaft carrier bearing (2), Figure 6, vertically in H-frame until driveline is as straight as possible between tractor PTO and cutter gearbox.
Cutting Height Adjustment for D80 Pull-Type Cutter (Figure 6)
Place tractor and cutter on a level surface.
Cutting height is raised and lowered with height adjustment crank (3) or optional hydraulic cylinder. Front to rear attitude is set with the compression link (1). The blade is approximately 9-1/4" below cutter deck. Select a cutting height, EXAMPLE 3".
Raise front end of deck with a jack to take the compression member (1) out of compression and remove the bolt connecting it to the tongue.
Raise front end of deck until both sides are 12-1/4" above the ground and block underneath to maintain this distance.
Raise rear end of deck until it is from 13-3/4" to 14" above the ground.
Connect compression member (1) to tongue. It may be necessary to raise or lower rear of deck to align hole.
Remove the blocks from under the deck and position each side skid 1/2" above the ground.
This complete procedure must be followed to properly set a new cutting height. Raising rear of deck with crank without changing the compression link position will result in an incorrect front-to-rear attitude setting.

STARTING AND STOPPING CUTTER
Cutter operating power is supplied from tractor PTO. Refer to your tractor manual for PTO engagement and disengagement instructions. Always operate PTO at 540 rpm. Know how to stop tractor and cutter quickly in case of an emergency.
When engaging PTO, the engine rpm should always be low. Once engaged and ready to start cutting, raise PTO speed to 540 rpm and maintain throughout cutting operation.

OPERATING TECHNIQUE
Proper ground speed will depend upon the height, type and density of material to be cut.
Normally, ground speed will range from 2 to 5 mph. Tall dense material should be cut at a low speed, while thin medium-height material can be cut at a higher ground speed. Always operate PTO at 540 rpm; this is necessary to maintain proper blade speed and produce a clean cut.
Under certain conditions, tractor tires may roll some material down and prevent it from being cut at the same height as the surrounding area. When this occurs, reduce tractor ground speed but maintain 540 rpm PTO speed. The lower speed will permit material to at least partially rebound.
Under some conditions, material will not rebound enough to be cut evenly, resulting in an uneven appearance. In general, lower cutting heights give a more even cut with less tendency to leave tire tracks.
The cutter is equipped with general purpose suction blades as standard equipment. These blades are intended for most conditions. Optional flat blades for light brush cutting and optional high fin blades for stalk shredding are available from your dealer.
Tips
Extremely tall material should be cut twice. Cut material higher the first pass. Then cut at desired height, at 90° to first pass. Remember, sharp blades produce cleaner cuts and require less power.
Analyze area to be cut to determine best procedure. Consider height and type of material and terrain type: hilly, level or rough. Plan your pattern to travel straight forward whenever possible.
WARNING
Inspect and clear area of stones, branches, or other hard objects that might be thrown, causing injury or damage.
Uneven Terrain
WARNING
Do not operate or transport on steep slopes.
Do not stop, start, or change directions suddenly on slopes.
Use extreme care and reduce ground speed on slopes and rough terrain.
Watch for hidden hazards on the terrain during operation.
Pass diagonally through sharp dips and avoid sharp drops to prevent hanging up tractor and cutter.
Practice will improve your skills in maneuvering rough terrain.
CLEANING
After Each Use
●Remove large debris such as clumps of dirt, grass, crop residue, etc. from machine.
●Inspect machine and replace worn or damaged parts.
●Replace any safety decals that are missing or not readable.
Periodically or Before Extended Storage
●Clean large debris such as clumps of dirt, grass, crop residue, etc. from machine.
●Remove the remainder using a low-pressure water spray.

LUBRICATION INFORMATION (FIGURE 7)
The accompanying chart gives the frequency of lubrication in operating hours, based on normal conditions. Severe or unusual conditions may require more frequent lubrication.
Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
Use an SAE 90W gear lube in gearbox.
Use a lithium grease of No. 2 consistency with a MOLY (molybdenum disulfide) additive for all locations. Be
sure to clean fittings thoroughly before attaching grease gun. When applied according to the lubrication chart, one good pump of most guns is sufficient. Do not overgrease.
Daily lubrication of the PTO slip joint is necessary. Failure to maintain proper lubrication can result in damage to U-joints, gearbox, tractor PTO and/or cutter driveline.

BLADE SERVICING (FIGURE 8)
WARNING
On pull-type units, a pin is installed to prevent the height adjustment crank from detaching. Do not operate or service unit unless pin is installed.
Blocking the cutter before working underneath provides additional safety. If a mechanical or hydraulic failure occurs, the blocks will support the cutter and prevent anyone under it from being crushed.
Inspect blades, each time before operating cutter, for condition and proper installation. Check to be sure blades are snug but still swivel on blade pin (see Blade Installation, page 20). Replace any blade that is bent, excessively nicked, worn or has any other damage. Small nicks can be ground out when sharpening.
Blade Removal (Figure 8)
Rotate crossbar until blade pin assembly is directly below access hole in rear of cutter frame. Remove bolt
(1) and blade pin lock clip (2). Slide keyhole plate (3) out of blade pin groove and remove. Remove spacers and drive pin out of crossbar.
NOTICE
■ If blade pin is seized in crossbar and extreme force will be required to remove it, support crossbar from below to prevent damage to spindle.
CAUTION
Your dealer can supply genuine replacement blades. Substitute blades may not meet original equipment specifications and may be dangerous.
