TRAINING
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.
SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
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.
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.
PREPARATION
Check that all hardware is properly installed. Always tighten to torque chart specifications unless instructed otherwise in this manual.
Air in hydraulic systems can cause erratic oper­ation and allows loads or equipment components to drop unexpectedly. When connecting equipment or hoses or performing any hydraulic maintenance, purge any air in hydraulic system by operating all hydraulic functions several times. Do this before putting into service or allowing anyone to approach the equipment.
Make sure all hydraulic hoses, fittings, and valves are in good condition and not leaking before starting power unit or using equipment. Check and route hoses carefully to prevent damage. Hoses must not be twisted, bent sharply, kinked, frayed, pinched, or come into contact with any moving parts. Operate moveable components through full operational range to check clearances. Replace any damaged hoses immediately.
Always wear relatively tight and belted clothing to avoid getting caught 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.
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.
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.
Never allow children or untrained persons to operate equipment.
TS1680 Safety Rules (6/29/2007)
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 system in “locked up” position at all times.

This heavy-duty cutter is designed for grass and weed mowing and shredding.
Recommended mowing speed for most conditions is from 2 to 5 mph.
Full chain shielding must be installed when operating in populated areas or other areas where thrown objects could injure people or damage property.
• If this machine is not equipped with full chain shielding, operation must be stopped when any­one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk of thrown objects. The mower deck and protec­tive devices cannot prevent all objects from escaping the blade enclosure in every mowing condition. and escape, traveling as much as 300 feet (92 m).
It is possible for objects to ricochet

CONNECT CUTTER TO TRACTOR (PULL-TYPE)
NOTICE
For tractors with a 1-3/8" diameter PTO shaft,
the horizontal distance from end of tractor PTO shaft to center of drawbar pin should be 14" for the 540 rpm cutter and 16" for the 1000 rpm cutter. Tractors with a 1-3/4" 20-spline PTO shaft should be set to 20". This will minimize joint knock and damage to drive components.
1. Adjust tractor drawbar to obtain the desired
drawbar-to-hitch-point distance.
NOTE: On some tractors, a drawbar kit must be used to obtain the required dimension. Check with your tractor dealer for assistance.
2. Attach parking jack to cutter tongue. Raise tongue to tractor drawbar height.
3. Secure cutter to tractor drawbar with a high­strength drawbar pin 3/4” or larger. Keep pin in place during operation.
4. Loop safety tow chain around tractor drawbar support. Secure the hook to a chain link that allows enough slack for proper hitch articulation.
5. Connect cutter driveline to tractor PTO shaft, making sure the spring-activated lock pin slides freely and is seated in tractor PTO splined groove.

condition.
2. Clean the fittings before connecting them to the tractor hydraulic ports.
3. Attach the hydraulic hose from the cutter to the tractor.
4. Route the hose through the hose holder on H­frame and be sure the hose can slide freely in the holder. Do not allow hose slack to drag on the ground or become caught on tractor protrusions.
5. From the operator position, start tractor and raise and lower deck several times to purge trapped air from the hydraulic cylinder.
CONNECT CUTTER TO TRACTOR (MOUNTED)
Tractor Adjustments
Before attaching tractor to cutter, install sway blocks or sway chains, or adjust stabilizer bars. Refer to the trac­tor operator's manual for instructions.
Install tractor front end weights as recommended by the tractor manufacturer to provide 20% of weight on front wheels.
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 front wheel weights, ballast in tires or front tractor weights. Weigh the tractor and equipment. Do not estimate.
Interference Check
1. Be sure that tractor 3-point lift links do not interfere
with hydraulic hoses, cutter driveline, or cutter frame.
2. Check for straight-ahead operation and at full­turning angles. If there is any interference, remove the lower lift links.
3. Contact between tractor lift links and cutter parts can cause damage, especially when turning.
Turning Limits for CV Driveline
You must not exceed a turning angle of 80 degrees at the head of the Constant Velocity driveline or damage will occur.
To check for potential excessive turn angle:
1. Disconnect driveline from tractor, start engine and turn as far right or left as possible.
2. Shut engine off, set parking brake, remove key, and try to connect CV driveline to tractor. If it cannot be connected, the angle is too severe.

DRIVELINE ADJUSTMENT (MOUNTED)
Attach the cutter to the tractor 3-point hitch (or quick hitch if available). Do not attach driveline at this time.
Shorten Driveline
1. Separate driveline into two halves and connect
them to the tractor PTO and gearbox input shaft.
2. Place the two halves parallel to one another to determine how much the driveline must be shortened. See Figure 4 for example.
NOTICE
If attaching cutter using a Quick Hitch the dis-
tance between the tractor PTO and the gearbox input shaft will increase. Follow steps as you would for the 3-point hitch to insure proper engagement.
Raise and lower cutter and measure the maximum and minimum distance between the tractor PTO shaft and the gearbox input shaft. Separate the driveline into two halves and lay them side-by-side with U-joints at oppo­site ends.
Set the two U-joints at the maximum distance mea­sures (this is the cutters lowest point of operation) and check the amount of overlap between the two drive halves. There must be at least 4 inches of overlap. If the driveline is too short (less than 4" overlap), contact your Woods dealer for a longer drive.

Pull-Type Units
On pull-type units with optional hydraulic cut­ting height adjustment, use a single-acting cylinder with a maximum extended length of 28-1/4" (718 mm) from attaching point center to center.
Driveline Interference Check
1. Check for clearance between driveline and cutter
deck.
2. With driveline properly attached to tractor and gearbox, slowly lift cutter and observe driveline. If clearance between driveline and cutter deck is less than 1 inch, shorten top link or limit upper travel of lower hitch arms. Refer to tractor operator's manual for instructions.
CUTTING HEIGHT ADJUSTMENT
Mounted Units
To adjust cutter for normal mowing, select a cutting height (example: 4 inches). Blades are approximately 1-3/4" above bottom of cutter. Dimension A plus 1-3/4" equals the cutting height.
Adjust the tractor 3-point hitch to a distance of 2-1/4" at position A to obtain a 4" cutting height. See Figure 8.
Using any of the optional height adjustment devices, raise or lower the tailwheel to obtain 2-1/2 to 2-3/4 inches at position B.
Adjust top link to provide 1-1/4 inches of clearance between the break link (2) and the rear of the lift links. See Figure 8. This clearance will allow the cutter to float over uneven terrain.
Cutting height range is from 2" to 13". A hydraulic cylin­der or ratchet jack is available for cutting height adjust­ment.
When selecting a cutting height, you should consider the area of operation. If the ground is rolling and has mounds the blades could contact, set the cutting height accordingly.
NOTICE
Avoid ground contact with blades. Striking
ground with blades produces one of the most dam­aging shock loads a cutter can encounter. If this occurs repeatedly, the cutter, driveline, and gear­boxes will be damaged.
To adjust cutter for normal mowing, select a cutting height (example: 4 inches). Blades are approximately 1-3/4" above bottom of cutter. Dimension A plus 1-3/4" equals the cutting height.
Using any of the optional cutting height mechanisms, raise or lower the tailwheel and set dimension A to 2­1/4" to achieve a 4" cutting height.
Loosen the jam nut on the attitude rod that runs from the tongue to the tailwheel. Adjust rod in or out until dimension B is approximately 1/2 inch more than dimension A. Refer to Figure 8.
MAN0577 (6/29/2007)
Operation 17
ATTITUDE ADJUSTMENT (PULL-TYPE)
TRACTOR OPERATION
Normal Mowing
For the most economical power use and best cutting results, the cutter should be from 1/2" to 3/4" higher at the rear than at the front.
For grass and weed mowing, adjust cutter to run level or with the front slightly lower.
Shredding
For shredding, it is better to set rear of cutter slightly lower than the front. How much lower depends on the material to be shredded. Determine the best setting for your situation by experimenting. Use a slow ground speed for better shredding.
DRIVELINE ADJUSTMENT (PULL-TYPE)
With the cutting height established, adjust the driveline carrier bearings in the H-frames so that the front drive­line is parallel to the ground with cutter in cutting posi­tion.
WHEEL SPACING
Wheels may be adjusted to any position for row crop shredding.
BLADE SELECTION
Optional stump jumpers are recommended for rugged terrain where hidden rocks, stumps, and other objects may be encountered.
There are two blade options available for this cutter: standard suction blades and flat-double edge blades. The standard suction blade is a general use, multipur­pose blade. The double-edge blade requires less horse power because it does not mulch or recut material. It is designed for use in areas where blade wear is a prob­lem. Sandy soils are extremely hard on blades.
Use care when operating around tree limbs and other low objects.
Use care and reduce ground speed on rough terrain. Always watch for hidden hazards.
Being knocked off or falling off tractor can result in seri­ous injury or death.
Only use a tractor with a Roll Over Protective Structure (ROPS) and seat belt. Securely fasten seat belt before starting tractor.
The cutter is operated with tractor controls. Engage the PTO at a low rpm to prevent excessive loads on the cutter drive system. Increase throttle to proper PTO speed 540 rpm (1000 rpm on "Q" models).
Be sure operator is familiar with all controls and can stop tractor and cutter quickly in an emergency. The operator should give complete, undivided attention to operating tractor and cutter.
OPERATING TECHNIQUE
Power for operating the cutter is supplied by the tractor PTO. Operate PTO at 540 rpm (1000 rpm on "Q" mod­els). Know how to stop the tractor and cutter quickly in an emergency.
Engage PTO at a low engine rpm to minimize stress on the drive system and gearbox. With PTO engaged, raise PTO speed to 540 rpm (1000 rpm on "Q" models) and maintain throughout cutting operation.
Gearbox protection is provided by a slip clutch with replacement fiber disc. The slip clutch is designed to slip when excessive torsional loads occur.
Move slowly into material. Adjust tractor ground speed to provide a clean cut without lugging the tractor engine. Use a slow ground speed for better shredding.
Proper ground speed will depend on the terrain and the material’s height, type, and density.
Blade rotation, viewed from the top of the cutter is counter-clockwise for the right crossbar, and clockwise for the left crossbar; the center crossbar is counter­clockwise on the 540 rpm models and clockwise on the 1000 rpm models.
When one cutting surface of the double-edge blade is worn, the opposite edge may be used by placing the blade on a crossbar of the opposite rotation. Blades from the right may be used on the left. Blades on the left may be used on the right.
NOTE: Blades must be moved in pairs. Never use one new blade and one used blade on a crossbar. Crossbar can become unbalanced.
18 Operation
Normally, ground speed will range from 2 to 5 mph. Tall, dense material should be cut at a low speed; thin, medium-height material can be cut at a faster ground speed.
Always operate tractor PTO at proper rpm (540 or
1000) to maintain blade speed and to produce a clean cut.
Under certain conditions tractor tires may roll down some grass and prevent cutting at the same height as the surrounding area. When this occurs, reduce your ground speed but maintain PTO at 540 rpm (1000 rpm on "Q" models). The lower ground speed will permit grass to rebound partially.

When beginning operation of the cutter, make sure that all persons are in a safe location. Slowly move into the material with the tractor PTO set at 540 or 1000 rpm.
Mowing Tips
Look down and to the rear and make sure area is clear before operating in reverse.
Do not operate or transport on steep slopes.
Do not stop, start, or change directions sud-
denly on slopes.
Use extreme care and reduce ground speed on slopes and rough terrain.
Watch for hidden hazards on the terrain during operation.
imum transport speed. Doing so could result in:
• Loss of control of the implement and tractor
• Reduced or no ability to stop during braking
• Implement tire failure
• Damage to the implement or its components.
Use additional caution and reduce speed when under adverse surface conditions, turning, or on inclines.
Never tow this implement with a motor vehicle.
1. Always transport with cutter in raised, locked
position.
2. Raise cutter with hydraulic cylinder.
3. Rotate transport lock over cylinder rod.
4. Lower cylinder against transport lock.
5. To lower cutter for operation, extend hydraulic
cylinder. Rotate transport lock back away from cylinder rod. Lower to desired cutting height.
Stop power unit and equipment immediately upon striking an obstruction. Turn off engine, remove key, inspect, and repair any damage before resuming operation.
Maximum recommended ground speed for cutting or shredding is 5 miles per hour. Adjust tractor ground speed by using higher or lower gears to provide a clean cut without lugging tractor engine.
Tall material should be cut twice. Cut material higher the first pass. Cut at desired height at 90 degrees the second pass.
Remember, sharp blades produce cleaner cuts and use less power.
Before entering an area, analyze it to determine the best procedure. Consider the height and type of mate­rial to be cut and the terrain type (hilly, level or rough, etc.).

WARNING
CAUTION
WARNING
The information in this section is written for operators who possess basic mechanical skills. If you need help, your dealer has trained service technicians available. For your protection, read and follow the safety informa­tion in this manual.
Keep all persons away from operator control area while performing adjustments, service, or maintenance.
If you do not understand any part of this manual and need assistance, see your dealer.
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.
BLOCKING METHOD
Never go underneath equipment (lowered to the ground or raised) unless it is properly blocked and secured. Never place any part of the body under­neath equipment or between moveable parts even when the engine has been turned off. Hydraulic system leak down, hydraulic system failures, mechanical failures, or movement of control levers can cause equipment to drop or rotate unexpect­edly and cause severe injury or death. Follow Oper­ator's Manual instructions for working underneath and blocking requirements or have work done by a qualified dealer.
To minimize the potential hazards of working under­neath the cutter, follow these procedures.
1. Jackstands with a load rating of 1000 lbs or more are the only approved blocking device for this cutter. Install a minimum of four jackstands (shown by Xs in Figure 10) under the cutter before working underneath unit.
Do not position jackstands under wheels, axles, or wheel supports. Components can rotate and cause cutter to fall.
The working surface must be level and solid to support the weight on the jackstands. Make sure jackstands are stable, both top and bottom. Make sure cutter is approximately level.
3. With full cutter weight lowered onto jackstands, test blocking stability before working underneath.
4. If cutter is attached to tractor when blocking, set the brakes, remove key, and block cutter before working underneath.
5. Securely block rear tractor wheels, in front and behind. Tighten tractor lower 3-point arm anti-sway mechanism to prevent side-to-side movement.
LUBRICATION
Do not let excess grease collect on or around parts, particularly when operating in sandy areas.
See Figure 10 for lubrication points and frequency or lubrication based on normal operating conditions. Severe or unusual conditions may require more fre­quent lubrication.
Use a lithium grease of #2 consistency with a MOLY (molybdenum disulfide) additive for all locations unless otherwise noted. Be sure to clean fittings thoroughly before attaching grease gun. One good pump of most guns is sufficient when the lubrication schedule is fol­lowed.
Gearbox Lubrication
1. For gearbox, use a high quality gear oil with a
viscosity index of 80W or 90W and an API service rating of GL-4 or -5 in gearboxes.
2. Fill gearbox until oil runs out the side plug on side of gearbox or oil level is between rings on dipstick when it is seated on top of gearbox. Check gearbox daily for evidence of leakage, and contact your dealer if leakage occurs.
Driveline Lubrication (Figure 10)
1. Lubricate the driveline slip joint every ten operating
hours. Failure to maintain proper lubrication could result in damage to U-joints, gearbox, and driveline.
2. Lower cutter to ground, disconnect driveline from tractor PTO shaft, and slide halves apart but do not disconnect from each other.
2. Consider the overall stability of the blocked unit. Just placing jackstands underneath will not ensure your safety.
MAN0577 (6/29/2007)
3. Apply a bead of grease completely around male half where it meets female half. Slide drive halves over each other several times to distribute grease.

Removing Blades (Figure 11)
NOTICE
If blade pin (1) is seized in crossbar and extreme
force will be needed to remove it, support crossbar from below to prevent gearbox damage.
1. Disconnect driveline from tractor PTO.
NOTE: Always replace or sharpen both blades at the
same time.
1. Inspect blade bolt (1) and bushing (4) for nicks or gouges. Replace blade bolt if any defects are found, Always replace lock nut (5) when changing blades.
2. Insert blade pin (1) through blade (2), align key on blade pin with keyway in crossbar, and push blade pin through crossbar.
2. Open blade access cover and align crossbar (3) with blade access hole in the cutter frame. Remove nut (5), top blade if installed, and bushing (4) from blade pin. Drive pin (1) out of crossbar (3).
3. Rotate crossbar (3) and repeat for opposite blade.
Installing Blades
Your dealer can supply genuine replacement blades. Substitute blades may not meet original
equipment specifications and may be dangerous.
NOTICE
Crossbar rotation viewed from the top of the
cutter, is counter-clockwise for the right gearbox and clockwise rotation on the left gearbox; the cen­ter crossbar is counter-clockwise on the 540 rpm models and clockwise on the 1000 rpm models. Be sure to install blade cutting edge to lead in correct rotation.
3. Install upper blade, if using shredder kit, and
bushing (4). Place a few drops of oil on pin and torque nut to 644 lbs-ft.
4. Repeat steps for opposite side.
NOTE: Blade should be snug but should swivel on
pin without having to exert excessive force. Oper­ating cutter when blades do not freely swing will cause excessive vibration.
Sharpening Blades
NOTICE
When sharpening blades, grind the same
amount on each blade to maintain balance. Replace blades in pairs. Unbalanced blades will cause excessive vibration, which can damage gearbox bearings. Vibration may also cause struc­tural cracks to cutter.
1. Sharpen both blades at the same time to maintain
balance. Follow original sharpening pattern.
2. Do not sharpen blade to a razor edge—leave at least a 1/16" blunt edge.

SLIP CLUTCH ADJUSTMENT
The slip clutch is designed to slip so that the gearbox and driveline are protected if the cutter strikes an obstruction.
A new slip clutch or one that has been in storage over the winter may seize. Before operating the cutter, make sure it will slip by performing the following operation:
1. Turn off tractor engine and remove key.
2. Remove driveline from tractor PTO.
3. Loosen six 12 mm cap screws (7) to remove all
tension from compression spring (8).
4. Hold clutch hub (3) solid and turn shaft to make sure clutch slips.
5. If clutch does not slip freely, disassemble and clean the flange yoke (1), clutch hub (3), drive plate (5), and thrust plate faces (6).
6. Reassemble clutch.
7. Compress each of the six compression springs (8)
by tightening the six cap screws (7) and lock nuts (10). The compression springs should be compressed to a height of 1-7/16", not including washer (9). The minimum spring height is 1.36". See Figure 13.
24 Owner Service
8. If a clutch continues to slip when the springs are
compressed to 1.36", check friction discs (2) for excessive wear. Discs are 1/8" when new. Replace discs after 1/16" wear. Minimum disc thickness is 1/16".
SHIELDING REPAIR
Full chain shielding must be installed when operating in populated areas or other areas where thrown objects could injure people or damage property.
• If this machine is not equipped with full chain shielding, operation must be stopped when any­one comes within 300 feet (92 m).
• This shielding is designed to reduce the risk of thrown objects. The mower deck and protec­tive devices cannot prevent all objects from escaping the blade enclosure in every mowing condition. and escape, traveling as much as 300 feet (92 m).
Repairing Optional Chain Shielding
Inspect chain shielding each day of operation and replace any broken or missing chains as required.
It is possible for objects to ricochet

WARNING
FLEXIBLE COUPLER RUBBER DISK REPLACEMENT
The flexible coupler side drive is designed to flex when striking heavy objects or during start-up to protect gear­boxes. The rubber disks will wear out over time and require replacement much like slip clutch disks. To maximize rubber disk life, lower tractor engine speed to an idle when engaging the PTO and avoid striking the ground with cutter blades.
Periodically inspect the disks for signs of cracking. A disk may run for some time after a crack starts but this is the first sign that disk replacement is required in the future.
To replace the disks, remove hardware items 6, 7, 8, and 9. Remove sleeves (7) from old disk and install in new disk. Reassemble and torque bolts to 85 lbs-ft. See Figure 14. Take special care not to rotate gearbox shaft and throw blades out of time. If rubber disks have failed and blades are hitting, you will need to re-time the blades per instructions on page 36.
SERVICING TIRES SAFELY
Used Aircraft Tires (Figure 15)
Do not attempt to mount a tire unless you have the proper equipment and experience to perform the job.
MAN0577 (6/29/2007)
Always maintain the correct tire pressure. Do not inflate tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure and result in a tire explosion. Welding can structurally weaken or deform the wheel.
When inflating tires, use a clip-on chuck and an exten­sion hose long enough to allow you to stand to the side — not in front of or over the tire assembly. Use a safety cage if available.
Check wheels for low pressure, cuts, bubbles, dam­aged rims, or missing lug bolts and nuts.
