stitute parts, modify, or connect in any other way.
TRAINING
Safety instructions are important! Rear all attachment and power unit
manuals; follow all safety rules and safety decal information. (Replace-
ment manuals and safety decals are available from your dealer. To locate
your nearest dealer, check the Dealer Locator at www.WoodsEquip-
ment.eu, or call +32 10 301111 in Belgium.) 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 card-
board, not hands or other body parts to check for leaks. Wear safety gog-
gles. 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.
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 equip-
ment 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 equip-
ment.
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 mov-
ing 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 specifica-
tions 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 equip-
ment for eyes, hair, hands, hearing, and head; and respirator or filter
mask where appropriate.
Make sure attachment is properly secured, adjusted, and in good operat-
ing 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.
Before starting power unit, check all equipment driveline guards for dam-
age. 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 condi-
tion. 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, front tractor wheels could raise up resulting in loss of steering.
The weight may be attained with front wheel weights, ballast in tires, front
tractor weights or front loader. 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.
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 per-
sonal injury or death.
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 alco-
hol or drugs.
The maximum transport speed for towed and semi-mounted machines is
40 km/h (24.85 mph). 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.
When transporting, pay special attention to overhead power lines and
make sure the machine has sufficient clearance to pass.
OPERATION
Stop power unit and equipment immediately upon striking an obstruction.
Turn off engine, set parking brake, remove key, inspect, and repair any
damage before resuming operation.
Do not allow bystanders in the area when operating, attaching, removing,
assembling, or servicing equipment.
Stay away from the machinery during a thunderstorm. Do not operate
machine during a thunderstorm. If lightning from a thunderstorm strikes
during operation, remain in the tractor cab. Do not make contact with the
ground of objects outside the machine. Do not leave the cab until the
storm has passed.
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 con-
trol and accident prevention are dependent upon the awareness, con-
cern, 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 oper-
ator.” We ask you to be that kind of operator.
SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
6 Safety
BW15_SR (15/04/2019)
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 sys-
tem failures, mechanical failures, or movement of control levers can
cause wings to drop unexpectedly and cause severe injury or death.
Full chain shielding must be installed at all times. Thrown objects could
injure people or damage property.
If the machine is not equipped with full chain shielding, operation must
be stopped.
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. It is possible
for objects to ricochet and escape, traveling as much as 300 feet
(92m).
Never direct discharge toward people, animals, or property.
Do not operate or transport equipment while under the influence of alco-
hol 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.
Always comply with all state and local lighting and marking requirements.
Never allow riders on power unit or attachment.
Power unit must be equipped with ROPS or ROPS cab and seat belt.

then cover hose ends, fittings, and hydraulic ports with tape.
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 mini-
mum spring length, replace the friction disks as shown.
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 fail-
ures, mechanical failures or movement of control levers can cause equip-
ment to drop or rotate unexpectedly and cause severe injury or death.

OPERATION
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 9.
Recommended tractor ground speed for most conditions is from .6 - 3.7 km/h
(1 to 6 mph.)
Always operate tractor PTO at 1000 RPM.
Full chain shielding must be installed at all times. Thrown objects
could injure people or damage property.
If the machine is not equipped with full chain shielding, operation
must be stopped
.
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.
It is
possible for objects to ricochet and escape, traveling as much as 92 m
(300 feet).
Look down and to the rear and make sure area is clear before operat-
ing in reverse.
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.
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 protec-
tive equipment for eyes, hair, hands, hearing, and head; and respirator or
filter mask where appropriate.
Stay away from the machinery during a thunderstorm. Do not operate
machine during a thunderstorm. If lightning from a thunderstorm strikes
during operation, remain in the tractor cab. Do not make contact with the
ground or objects outside the machine. Do not leave cab until the storm
has passed.
CONNECTING CUTTER TO TRACTOR
NOTICE
For tractors with a 3.5 cm (1-3/8 in.) diameter PTO shaft, the horizon-
tal distance from the end of the tractor PTO shaft to the centre of drawbar
pin should be 406.4 mm (16 in.) Tractors with 4.5 cm (1-3/4 in.) 20-spline
PTO shaft should be set to 50.8 cm (20 in.) This will minimize joint knock
and damage to drive components.
Figure 1. Cutter to Tractor Connection
Mechanical Connection
1. Remove unauthorized tow device by unlocking and removing specific
device.
2. Attach cutter using appropriate towing eye hardware.
3. Attach safety tow chain (Figure 1) to drawbar support. Leave enough
slack for turning.
4. Connect cutter driveline to tractor PTO shaft, making sure the spring-
activated lock pin slides freely and is seated in tractor PTO splined
groove.
5. Attach driveline shield tether chain to tractor drawbar to prevent rotation.
NOTE: To prevent shield rotation, attach driveline shield tether chain to
gearbox shield at hole provided.
6. Adjust nuts (4) so tongue clevis (A) is parallel with the tractor drawbar.
7. Remove parking jack (Figure 1) 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.
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. Raise unit with centre lift cylinder and extend wing cylinders. Stop tractor
and remove transport lock pins from wing stops and tranport stop as
shown in Figure 2 and Figure 3, page 13.
6. From the operator position, start tractor and raise and lower deck several
times to purge trapped air from the hydraulic cylinder.
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 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.

12 Operation
MAN1279 (15/04/2019)
Cutting Height Adjustment
NOTICE
Avoid ground contact with blades. Striking ground with blades pro-
duces one of the most damaging shock loads a cutter can encounter. If
this occurs repeatedly, the cutter, driveline, and gearboxes will be dam-
aged.
Cutting height range is from 50 mm (2 in.) to 381 mm (15 in). A hydraulic cylin-
der is used 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. The cutting height (blade edge) is approximately 25.4 mm
(1 in.) above the bottom of the side skid.
Cutting Height (Normal Mowing) - Centre Section
1. Position the cutter on a hard level surface and select an approximate
cutting height, for example 152.4 mm (6 in.).
2. Raise wings and lock them in the UP position.
3. Use the hydraulic cylinder to raise or lower the centre section to obtain a
distance of 127 mm (5 in.) from bottom edge of skid shoe to the ground.
4. Place jackstands under the four corners of the centre section. See
illustration on page 15. Lower centre section to relieve pressure on
attitude rod nuts.
5. Loosen outer jam nut on the attitude rods.
6. Adjust inner nuts in or out until the rear of the cutter is approximately 12.7
mm (1/2 in.) higher than the front. See Figure 1A. It’s used as a starting
point for adjusting the attitude rod, based on different tongue height and
wheel options.
7. Raise cutter, remove jackstands and check deck height. Tighten jam nuts
against sleeve.
Figure 1A. Attitude Rod Adjustment
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.
4. Make sure jam nuts are tightened once wing is leveled.
When using the cutter to shred, the rear of the cutter deck should be approxi-
mately 12.7 mm to 25.4 mm (1/2 in. to 1 in.) lower than the front.
TRACTOR OPERATION
Power unit must be equipped with Roll Over Protection System
(ROPS) or ROPS cab and seat belt. Keep seat belt securely fastened. Fall-
ing off power unit can result in death from being run over or crushed.
Keep foldable ROPS system in “locked up” position at all times.
Use care when operating around tree limbs and other low objects. Avoid being
knocked off tractor and being injured.
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 recom-
mended 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 atten-
tion to operating tractor and cutter.
CUTTER OPERATION
Look down and to the rear and make sure area is clear before oper-
ating in reverse.
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.
Stop power unit and equipment immediately upon striking an
obstruction. Turn off engine, remove key, inspect, and repair any damage
before resuming operation.
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
1000 RPM for Q models.
Know how to stop the tractor and cutter quickly in an emergency.
To stop cutter when operating under normal conditions, reduce tractor RPM to
idle and disengage PTO to reduce freewheeling on cutting elements.
Engage PTO at a low engine rpm to minimize stress on the drive system and
gearbox.
With PTO engaged, raise PTO speed to 1000 RPM 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.
Normally, ground speed will range from 3 to 8 km/h (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 1000 RPM to maintain blade speed and to pro-
duce 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 1000 RPM. The lower ground speed
will permit grass to rebound partially.
Mowing Tips
Maximum recommended ground speed for cutting or shredding is 10 km/h (6
mph). 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.).

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 till-
ing. It may also be used to shred pruning in orchards, groves and vineyards.
Each shredding operation may require a different set-up. 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 centre sec-
tion to the ground.
TRANSPORTING
Always raise unit and install transport locks before transporting.

OWNER SERVICE
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 the ground, raise cutter, and engage transport lock-up in the
locked position. Attach parking jack and lower to the ground. Securely
block all four corners of the centre 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.
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, cleaning, or maintenance with engine run-
ning.
If you do not understand any part of this manual and need assis-
tance, see your dealer.
Always wear relatively tight and belted clothing to avoid entangle-
ment in moving parts. Wear sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing, and head; and respirator or
filter mask where appropriate.
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 sys-
tem 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.
Do not position jackstands under wheels, axles, or wheel supports. Compo-
nents can rotate and cause cutter to fall.
1. Jackstands with a load rating of 453.6 kg (1000 lbs.) or more are the only
approved blocking device for this cutter. Install jackstands (shown by Xs
in Figure 6) 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 6 for lubrication points and frequency or lubrication based on nor-
mal operating conditions. Severe or unusual conditions may require more fre-
quent 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 thor-
oughly 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–4 or –5 in gearboxes.
Check gearbox daily for evidence of leakage, and contact your dealer if leak-
age occurs. Use sealant on vent plug threads during installation. Check vent
plug periodically and clean if it does not 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.
Seasonal Lubrication
In addition to the daily recommended lubrication, a more extensive application
is recommended seasonally.
1. Fill CV double yokes with 20 pumps of grease with the joints in a straight
line.
2. Articulate CV body to maximum angle several times to ensure full
coverage of joints.
3. Place joints in the straight position and add 10 additional pumps of
grease to both joints.
4. Wipe telescoping drive clean of all old grease and contaminants.
5. Add a thin layer of new grease over telescoping drive.
BLADES
Before working underneath, read manual instructions, securely
block up, and check stability. Secure blocking prevents equipment from
dropping due to hydraulic leak down, hydraulic system failure, or
mechanical component failure.
Your dealer can supply genuine replacement blades. Substitute
blades may not meet original equipment specifications and may be dan-
gerous.
Blade Removal (Figure 7)
Figure 7. Blade Assembly
1. Disconnect driveline from tractor PTO.
2. Raise cutter and block securely (see Figure 6).
3. Align crossbar (8) with blade access hole in the cutter frame. Remove
cap screw (50), blade pin lock clip (12, keyhole plate (11), and shims (9 &
10). Carefully drive blade pin (7) out of crossbar.
4. Rotate crossbar and repeat for opposite blade.
NOTICE
If blade pin (7) is seized in crossbar and extreme force will be
needed to remove it, support crossbar from below to prevent gearbox
damage.
Blade Installation (Figure 7)
NOTICE
Crossbar rotation has clockwise rotation on left gearbox and anti-
clockwise rotation on the right and centre gearboxes when looking down
on cutter. Be sure to install blade cutting edge to lead in correct rotation.
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.
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 centre 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.
If you do not understand any part of this manual and need assis-
tance, see your dealer.
Always wear relatively tight and belted clothing to avoid entangle-
ment in moving parts. Wear sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing, and head. Wear a respirator
or filter mask where appropriate.
NOTE: Always replace or sharpen both blades at the same time.
1. Inspect blade pin (7) for nicks or gouges, and if you find any, replace the
blade pin.
2. Insert blade pin through the blade. Blade should swivel on blade pin; if it
doesn’t, determine the cause and correct.
3. Align crossbar (8) with blade access hole in cutter frame. Apply a liberal
coating of Never-Seez
®
or equivalent to blade pin and crossbar hole.
Make sure blade offset is down away from cutter.
4. Insert blade pin (7) through blade. Push blade pin through crossbar.
5. Install shims (9 & 10) over blade pin.
NOTE: Only use enough shims to allow keyhole plate (11) to slide into
blade pin groove.
6. Install blade clip (12) over keyhole plate and into blade pin groove.
7. Secure into position with cap screw (50). Torque cap screw to 115 Nm
(85 lbs-ft).
8. Repeat steps for opposite side.
NOTE: Blade should be snug but should swivel on pin without having to
exert excessive force. Blade should not move more than a 1/4 inch up or
down at the tip. Keep any spacers not used in the installation as replace-
ments or for future installation.
Blade Sharpening
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 1.6 mm (1/16 in.)
blunt edge.
3. Do not sharpen back side of blade.

2-PLATE SLIP CLUTCH ADJUSTMENT (FIGURE 9)
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected 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 10 mm cap screws (6) to remove all tension from Belleville
spring plate (5).
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 thrust plate faces
(4), flange yoke (1), and clutch hub (3).
6. Reassemble clutch.
7. Tighten Belleville spring plate (5) until it is against the thrust plate (4) of
the clutch, and then back off each of the six nuts by 2 full revolutions. The
gap between Belleville spring plate and thrust plate should be 3.18 mm
(1/8 in) as shown in Figure 9.
8. If a clutch continues to slip when the spring is compressed to 3.18 mm
(1/8 in) gap, check friction discs (2) for excessive wear. Discs are 3.18
mm (1/8 in) when new. Replace discs after 1.16 mm (1/16 in) wear.

4-PLATE SLIP CLUTCH ADJUSTMENT
(FIGURE 10)
The slip clutch is designed to slip so that the gearbox and driveline are pro-
tected 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. Tighten four nuts (12) to remove pressure from the clutch plates (2).
Repeat for all three clutches.
3. Start tractor at low throttle and slowly engage PTO and allow clutches to
slip for 5 seconds. Disengage PTO and turn off tractor engine.
4. If clutches slip freely, completely loosen nuts (12).
5. If clutch does not slip freely, disassemble and clean plates (4, 6, & 7),
flange yoke (1), and clutch hub (3).
6. Reassemble clutch.
7. Tighten Belleville spring (5) with nuts (11) until it is against the thrust plate
(4) of the clutch. Back off each of the four nuts (11) until gap between
Belleville spring and thrust plate is 6 mm (.236 in) as shown in Figure 10.
8. If a clutch continues to slip when the spring is compressed to 6 mm (.236
in) gap, check friction discs (2) for excessive wear. Discs are 3.18 mm
(1/8 in) when new. Replace discs after 1.58 mm (1/16 in) wear. Minimum
disc thickness is 1.58 mm (1/16 in).
NOTE: When storing cutter for long periods of time, relieve the pressure on the
clutch discs by tightening the four nuts (12) on each clutch. Completely loosen
nuts (12) to return to service.

SHIELDING REPAIR
Full chain shielding must be installed at all times. Thrown objects
could injure people or damage property.
If the machine is not equipped with full chain shielding, operation
must be stopped.
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.
It is
possible for objects to ricochet and escape, traveling as much as 92 m
(300 feet).
Repairing Chain Shielding:
1. Inspect chain shielding each day of operation and replace any broken or
missing chains as required.
2. Replace any missing hardware.
SERVICE TIRES SAFELY
Used Aircraft Tires (Figure 11)
Do not attempt to mount a tire unless you have the proper equipment and
experience to perform the job.
Always maintain the correct tire pressure. Do not inflate tires above the recom-
mended 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.
Never remove split rim assembly hardware (A) with the tire inflated.

CLEANING
Never perform cleaning, servicing, or maintenance with engine running.
Before cleaning, 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.
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.
Do not climb on machines or ladder to clean. Clean machine with wings
in lowered position only.
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.
1. Be careful when spraying near scratched or torn safety decals or near
edges of decals as water spray can peel decal off surface.
2. Be careful when spraying near chipped or scratched paint as water
spray can lift paint.
3. If a pressure washer is used, follow the advice of the pressure washer
manufacturer.
Inspect machine and replace worn or damaged parts.
Sand down scratches and the edges of areas of missing paint and coat
with Woods spray paint of matching color (purchase from your Woods
dealer).
Replace any safety decals that are missing or not readable (supplied free
by your Woods dealer). See Safety Decals section for location drawing.
