INSTALLATION
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!
Hydraulics must be connected as instructed in this manual. Do not substitute parts, modify, or connect in any other way.
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.
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. CON-
BW180LH_SR (10/15/2009)
TACT A PHYSICIAN IMMEDIATELY IF FLUID ENTERS SKIN OR EYES. DO NOT DELAY.
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.
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.
After connecting hoses, check that all control lever positions function as instructed in the Opera­tor's Manual. Do not put into service until control lever and equipment movements are correct.
Set tractor hydraulic relief valve at 2500 psi (170 bars) (17,000 kPa) to prevent injury and equipment damage due to hydraulic system failure.
Your dealer can supply original equipment hydraulic accessories and repair parts. Substitute parts may not meet original equipment specifica­tions and may be dangerous.
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.

SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Before starting power unit, check all equipment driveline guards for damage. Replace any damaged guards. Make sure all guards rotate freely on all drivelines. If guards do not rotate freely on drive­lines, repair and replace bearings 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 system in “locked up” position at all times.
Remove accumulated debris from this equip­ment, power unit, and engine to avoid fire hazard.
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.
Do not put this equipment into service unless all side skids 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.
TRANSPORTATION
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.
Always raise unit and install transport locks before transporting. Leak down or failure of mechanical or hydraulic system can cause equip­ment to drop.
Always attach safety chain to tractor drawbar when transporting unit.
Always comply with all state and local lighting and marking requirements.
Never allow riders on power unit or attachment.
Do not operate PTO during transport.
Do not operate or transport on steep slopes.
Do not operate or transport equipment while
under the influence of alcohol or drugs.
The maximum transport speed for towed and semi-mounted machines is 20 mph (32 km/h). Regardless of the maximum speed capability of the towing tractor, do not exceed the implement’s max­imum 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.
OPERATION
Do not allow bystanders in the area when oper­ating, attaching, removing, assembling, or servic­ing equipment.
Never walk, stand, or place yourself or others under a raised wing or in the path of a lowering wing. Hydraulic system leak-down, hydraulic sys­tem failures, mechanical failures, or movement of control levers can cause wings to drop unexpect­edly and cause severe injury or death.
Full chain or rubber 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 or rubber 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).
Never direct discharge toward people, animals, or property.
Do not operate or transport equipment while under the influence of alcohol or drugs.
Operate only in daylight or good artificial light.
Keep hands, feet, hair, and clothing away from
equipment while engine is running. Stay clear of all moving parts.
It is possible for objects to ricochet

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.
Always sit in power unit seat when operating controls or starting engine. Securely fasten seat belt, place transmission in neutral, engage brake, and ensure all other controls are disengaged before starting power unit engine.
Operate tractor PTO at 540 RPM. Do not exceed.
Raise or lower wings slowly to prevent personal
injury or damage to cutter.
Connect PTO driveline directly to power unit PTO shaft. Never use adapter sleeves or adapter shafts. Adapters can cause driveline failures due to incorrect spline or incorrect operating length and can result in personal injury or death.
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.
Watch for hidden hazards on the terrain during operation.
Stop power unit and equipment immediately upon striking an obstruction. Turn off engine, remove key, inspect, and repair any damage before resuming operation.
Continuous operation while the clutch is slip­ping could cause heat build-up resulting in fire. Adjust slip clutch pressure by tightening springs to the dimension shown in the “Owner Service” sec­tion. If clutch is set to minimum spring length, replace the friction disks as shown.
On pull-type or semi-mounted 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.
MAINTENANCE
Before servicing, adjusting, repairing or unplug­ging, stop tractor engine, place all controls in neu­tral, set park brake, remove ignition key, and wait for all moving parts to stop.
Before dismounting power unit or performing any service or maintenance, follow these steps: disengage power to equipment, lower the 3-point hitch and all raised components to the ground, operate valve levers to release any hydraulic pres­sure, set parking brake, stop engine, remove key, and unfasten seat belt.
Before working underneath, disconnect driveline from tractor, lower wings to ground, raise cutter, and pin transport bar in raised position. Attach parking jack and lower to ground. Securely block all four corners of center section and each wing with jack­stands. Blocking up prevents the cutter from drop­ping due to hydraulic leak down, hydraulic system failure, or mechanical component failure.
Do not modify or alter or permit anyone else to modify or alter the equipment or any of its compo­nents in any way.
Your dealer can supply original equipment hydraulic accessories and repair parts. Substitute parts may not meet original equipment specifica­tions and may be dangerous.
To prevent contamination during maintenance and storage, clean and then cover hose ends, fit­tings, and hydraulic ports with tape.
Do not allow bystanders in the area when oper­ating, attaching, removing, assembling, or servic­ing equipment.
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.

OPERATION
DANGER
WARNING
CAUTION
The designed and tested safety of this machine depends on it being operated within the limitations as explained in this manual. Be familiar with and follow all safety rules in the manual, on the cutter and on the tractor.
The safe operation of this cutter is the responsibility of the operator, who must be properly trained. The opera­tor should be familiar with the equipment and all safety practices before starting operation. Read the safety information on page 7 through page 13.
Recommended tractor ground speed for most condi­tions is from 1 to 6 mph.
Always operate tractor PTO at 540 rpm.
Full chain or rubber 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 or rubber 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).
Never allow children or untrained persons to operate equipment.
Do not allow bystanders in the area when oper­ating, attaching, removing, assembling, or servic­ing equipment.
Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.
It is possible for objects to ricochet
equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where appropriate.
CONNECTING CUTTER TO TRACTOR
NOTICE
For tractors with a 1-3/8" diameter PTO shaft,
the horizontal distance from the end of the tractor PTO shaft to the center of drawbar pin should be 14" for 540 rpm cutter. This will minimize joint knock and damage to drive components.
Figure 1. Cutter to Tractor Connection
1. Attach cutter using a 1-1/2" clevis pin and clip.
2. Attach safety tow chain (32) to drawbar support.
Leave enough slack for turning (Figure 1).
3. Connect cutter driveline to tractor PTO shaft, making sure the spring-activated lock pin slides freely and is seated in tractor PTO splined groove.
4. Remove parking jack (29) from the tongue and attach it to the storage post on the front of the left wing.
Hydraulic Connection
1. Inspect hydraulic hoses to ensure they are in good
condition.
2. Clean the fittings before connecting them to the tractor hydraulic ports.
Stop power unit and equipment immediately upon striking an obstruction. Turn off engine, remove key, inspect, and repair any damage before resuming operation.
Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled work shoes and protective
14 Operation
3. Route the hose through the hose holder at the
hitch 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.
4. Attach the hydraulic hose to the tractor.
5. From the operator position, start tractor and raise
and lower deck several times to purge trapped air from the hydraulic cylinder.
MAN0810 (9/24/2009)
Interference Check
WARNING
1. Be sure that tractor 3-point lift links do not interfere with hydraulic hoses, cutter driveline, or cutter frame.
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. The cutting height (blade edge) is approxi­mately 1" above the bottom of the side skid.
2. Check for straight-ahead operation and at full turning 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.
CV Driveline Turning Limits
NOTICE
You must not exceed a turning angle of 80
degrees at the head of the Constant Velocity drive­line or damage will occur.
1. To check for potential excessive turn angle,
disconnect the driveline from tractor.
2. Start engine and turn as far right or left as possible.
3. Shut engine off and try to connect CV driveline to
tractor. If it cannot be connected, the turn angle is too severe.
4. Restart engine and straighten angle slightly, shut off engine and try to connect CV driveline to tractor.
5. Repeat the process until the driveline can be connected. The point at which the driveline can be connected is the maximum turn that should be made.
Cutting Height (Normal Mowing) - Center Section
1. Position the cutter on a hard level surface and
select an approximate cutting height, Example 6".
2. Raise wings and lock them in the UP position.
3. Use any of the optional cutting height mechanisms
to raise or lower the center section to obtain a distance of 5" from bottom edge of skid shoe to the ground.
4. Loosen jam nuts on the attitude rod that runs from the wheel yoke to the tongue.
5. Adjust rod in or out until the rear of the cutter is approximately 1/2" higher than the front.
6. Tighten jam nuts against sleeve.
Cutting Height (Normal Mowing) - Wings
1. Lower wings to normal mowing position.
2. Loosen the jam nut on the adjustable link (turn
buckle).
3. Lengthening the link will raise the wing, shortening the link will lower the wing. The rear edge of the wing should be parallel to the ground.
Cutting Height Adjustment
On pull-type or semi-mounted 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.
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.
Cutting height range is from 1" to 12". A hydraulic cylin­der or ratchet jack is available for cutting height adjust­ment.
MAN0810 (9/24/2009)
When using the cutter to shred, the rear of the cutter deck should be approximately 1/2" to 1" lower than the front.
TRACTOR OPERATION
Use care when operating around tree limbs and other low objects. Avoid being knocked off tractor and being injured.
Only use a tractor with a Roll Over Protection Structure (ROPS) and seat belt. Securely fasten seat belt.
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 recommended PTO operating RPM.
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.
Operation 15
CUTTER OPERATION
WARNING
WARNING
CAUTION
When beginning operation of the cutter, make sure that all persons are in a safe location.
Power for operating the cutter is supplied by the tractor PTO. Operate PTO at 540.
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 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.
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.
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 6 miles per hour. Adjust tractor ground speed by using higher or lower gears to provide a clean cut without lugging 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.
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 540 RPM 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. The lower ground speed will permit grass to rebound par­tially.
Mowing Tips
Look down and to the rear and make sure area is clear before operating in reverse.
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.).
Shredding
The cutter may be used to shred various crops includ­ing green manure, straw, stubble, asparagus residue, corn stalks and similar crops in preparation for tilling. It may also be used to shred pruning in orchards, groves and vineyards.
Each shredding operation may require a different set­up. Start with front edge of cutter high. Adjust up or down as necessary with attitude rod. Experiment until you obtain the results you want.
When shredding attitude is set, check that the distance from the bottom rear edge of the wing to the ground matches the bottom edge of the rear center section to the ground.

OWNER SERVICE
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.
Before working underneath, disconnect drive­line from tractor, lower wings to ground, raise cut­ter, and pin transport bar in raised position. Attach parking jack and lower to ground. Securely block all four corners of center section and each wing with jack stands. Blocking up prevents the cutter from dropping due to hydraulic leak down, hydrau­lic system failure, or mechanical component fail­ure.
BLOCKING METHOD
To minimize the potential hazards of working under­neath the cutter, follow these procedures:
Before performing any service or maintenance, lower equipment to ground or block securely, turn off engine, remove key, and disconnect driveline from tractor PTO.
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.
Service and maintenance work not covered in OWNER SERVICE must be done by a qualified dealership. Special skills, tools, and safety proce­dures may be required. Failure to follow these instructions can result in serious injury or death.
Before servicing, adjusting, repairing or unplug­ging, stop tractor engine, place all controls in neu­tral, set park brake, remove ignition key, and wait for all moving parts to stop.
Never perform service or maintenance with engine running.
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.
Do not position jackstands under wheels, axles, or wheel supports. Components can rotate and cause cut­ter to fall.
1. Jackstands with a load rating of 1000 lbs. or more are the only approved blocking device for this cutter. Install jackstands (shown by Xs in Figure 5) under the cutter before working underneath unit.
2. Consider the overall stability of the blocked unit. Just placing jackstands underneath will not ensure your safety.
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 5 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
For gearbox, use a high quality gear oil with a viscosity index of 80W or 90W and an API service rating of GL–
20 Owner Service
4 or –5 in gearboxes. Fill gearbox until oil runs out the side plug on gearbox. Check gearbox daily for evi­dence of leakage, and contact your dealer if leakage occurs. Use sealant on vent plug threads during instal­lation. Check vent plug periodically and clean if it doesn’t relieve pressure.
Driveline Lubrication
1. Lubricate the driveline slip joint every eight
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.
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.
