OPERATION
The designed and tested safety of this machine depends on it being operated within the limitations as explained in the manual. Be familiar with and follow all safety rules in this manual, the tractor manual and safety decals on the tractor and mower.
A WARNING
Do not exceed PTO speed of 1000 rpm maxi-
mum.
The safe operation of this machine is the responsibility of the operator. The operator should be familiar with the mower and tractor and all safety practices before starting operation. Read and follow the safety rules on page 5 through page 7.
The mower is designed for lawn or grass mowing. It is not designed for rough conditions or heavy weed mow­ing.
It is equipped with suction type blades for best results in lawn mowing. Optional low suction blades are avail­able for use in sandy conditions.
The warranty for this mower appears on the inside back cover of this manual. Record the model and serial numbers of your mower in the spaces provided above the warranty. Provide this information to your dealer to obtain correct repair parts.
Take all possible precautions when leaving tractor unattended: disengage PTO, lower mower, shift into neutral, set parking brake, stop engine and remove key from ignition.
DAILY CHECK LIST
___ Check that mower is properly and securely
attached to tractor.
___ During inspection, check that all nuts and bolts
are secure and clevis pins are properly cotter pinned.
Adjustment is accomplished by lowering lift arms and inserting lift chains into keyhole lift lugs. Raise the mower, checking to ensure it does not contact any part of tractor. Take up links, one or two at a time, until the desired height is obtained.
There is a long and short slot in the rear lift lugs. Level mower by using these slots as needed.
After setting upper lift limit, lower mower to desired cut­ting height. Set lower stop of mower hydraulic control lever at this point. This will allow you to raise the mower when necessary and return to the pre-set cutting height.
CUTTING HEIGHT ADJUSTMENT WITH CASTERS
The caster arm has five holes for adjustment. Cutting height is adjusted by changing the adjustment bracket hole alignment with the caster arm.
There are two holes on the frame rail to mount the caster arm. Use the rear hole for settings up to 3". Use the front hole for settings above 3".
Whenever adjustments are made to the casters, care­fully raise mower to ensure casters do not come in con­tact with any part of tractor. Should any interference occur, readjust lift chains.
Set lower stop of tractor hydraulic control lever to pre­vent chains rubbing belt.
IMPORTANT
Be sure lift chains do not interfere with drive
belt.
Always raise mower off casters when backing
up and turning at the same time to prevent casters from locking up on front tires.
Attitude Adjustment
___ Check condition of blades and security of attach-
ment.
CUTTING HEIGHT ADJUSTMENT WITH­OUT CASTERS
Mower cutting height is raised, lowered and maintained using tractor hydraulics and lift chains. Proper lift chain adjustment is essential. The chains must be adjusted so that tractor lift arms are in their highest position before the lift or any part of mower is within 1/4" of con­tacting tractor or mower lift stops. Improper lift chain adjustment could result in damage to lift mechanism or tractor.
8 Operation
Figure 1. Attitude Adjustment
Place tractor and mower on a level surface to check and adjust mower attitude. For best mowing results, dimension “A” should not be more than 1/2" higher and never lower than dimension “B” (except when using a leaf mulcher or with some tractor tire configurations, it may be necessary to adjust rear of mower approxi-
32695 (Rev. 11/17/2006)
mately 1/4" lower than front to prevent belt from rub­bing on mower.)
Dimension “B” is set by adjusting optional casters or lift chains.
Dimension “A” is set by raising or lowering channel arms in push bars.
IMPORTANT
Any adjustment to either dimension “A” or “B”
will require checking the other adjustment.
Set desired cutting height with casters or lift chains then adjust for dimension “A”.
Check attitude by placing a straight edge along outside edge of mower as shown in Figure 1. Measure from bottom of straight edge to ground. The measurement at dimension “B” should be level with or approximately 1/2" lower than the rear. The measurement at dimen­sion “A” should never be lower than the one at dimen­sion “B” (except when using a leaf mulcher or with some tractor tire configurations, it may be necessary to adjust rear of mower approximately 1/4" lower than front to prevent belt from rubbing on mower.)
To determine cutting height, it is necessary to subtract the distance the blade is below mower from the mea­surement at dimension “B”. Subtract 4-7/8" from dimension “B”; the remainder is the cutting height.
Be sure mower is level side to side using these mea­surements. If it is not, check to be sure casters are set in same hole, and that channel arms and push bars are set in same hole on each side. Minor adjustments can be made by using slots in rear lift bracket for adjust­ments.
Do not operate mower in vicinity of other per-
sons.
Do not allow riders on tractor or mower.
PRE-OPERATION CHECK LIST
___ Check to ensure blades are sharp and secure
and cutting edge is positioned in the direction of blade rotation (counter-clockwise as viewed from top of mower).
___ Always operate tractor PTO at 1000 rpm maxi-
mum when mowing.
___ Check to make sure all safety shielding is prop-
erly installed and is in good condition. Be sure discharge chute or side shield is installed.
___ Check cutting height adjustment.
___ Clear area to be mowed of debris that could be
picked up and thrown by mower.
___ Place tractor transmission in neutral and be sure
PTO is disengaged before attempting to start tractor engine.
___ Make sure all critical tractor adjustments such as
brake and clutch pedal travel, etc., are set to trac­tor manufacturer’s specifications.
STARTING & STOPPING MOWER
Power for operating the mower is supplied by tractor power take off (PTO). Refer to your tractor manual for PTO operating instruction.
A WARNING
When making cutting height or attitude changes, be sure to check belt alignment. (Refer to Belt Alignment in Assembly section on page 23.)
IMPORTANT
Improper belt alignment or tension can cause
premature belt failure.
Side Skid Adjustment
With cutting height established, adjust side skids at least 1/2" above ground level. Properly adjusted side skids are designed to carry mower over uneven ground and minimize scalping. Never adjust side skids to be in constant contact with ground.
A WARNING
Allow no children or unqualified persons to
operate this equipment.
Do not exceed PTO speed of 1000 rpm maxi-
mum.
A CAUTION
Stop mower and tractor immediately upon
striking an obstructions. Inspect mower and repair any damage before resuming operation.
Should mower become plugged, causing belt to slip over two seconds, raise mower just enough to clear plug and continue running for at least two minutes, allowing pulleys to cool. Stopping the mower with belt in contact with a very hot pulley will bake and ruin belt. Do not raise mower higher than necessary, to reduce the risk of thrown objects.
Commencing Mowing
When engaging PTO, the engine rpm should always be low. Once engaged and ready to start mowing,
32695 (Rev. 11/17/2006)
Operation 9
increase PTO speed to 1000 rpm and maintain throughout cutting operation.
During operation mowing vibration tends to loosen hardware. All hardware should be checked regularly to maintain proper torque. It is good practice to check mower before each operation to ensure all hardware is tight.
IMPORTANT
Always raise mower off casters when backing
and turning at the same time to prevent casters from locking up on front tractor tires.
Before mowing, analyze the area to determine the best mowing procedure. Consider the height, type of grass and the terrain type (hilly, level or rough).
A DANGER
Keep away. To avoid serious injury or death
from thrown objects or blade contact, never oper­ate mower without discharge chute or side shield installed.
MOWING TECHNIQUES
Mowing Speed
The condition of the terrain to be cut will determine the smoothness of final results. For best results, mower blades should be kept sharp at all times and the mower as level as possible. When mower blades show exces­sive wear, they should be replaced.
Proper ground speed for mowing will depend on the height, type and density of grass to be cut. Normally, ground speed will range from two to five mph. Tall, dense grass should be mowed at lower speeds, while thin, medium height grass can be cut at a faster ground speed.
Always operate tractor PTO at 1000 rpm maximum when mowing. This is necessary to maintain proper blade speed to produce a clean cut. Under certain sea­sonal conditions, front tractor tires may roll some grasses down and prevent them from being cut to the same height as the surrounding area. When this occurs, reduce the tractor ground speed, operating tractor PTO at 1000 rpm. The slower speed will permit grasses to at least partially rebound and be cut.
Under some conditions, the grasses will not rebound enough to be cut evenly, resulting in an uneven appearance. In general, lower mowing heights give a more even cut with less tendency to leave tire tracks.
A DANGER
Keep hands and feet away from discharge
opening.
A WARNING
Pick up all rocks, twigs and other debris before
mowing. Enter new areas carefully. Cut grass higher the first time to allow mower to clear unseen objects. Never assume an area is clear. Always check!
Clear mowing area of all people when operating
mower. Thrown objects could injure bystanders.
Mow with uncut grass to the right. This will distribute the clippings over the cut area. Discharging clippings over uncut grass will cause a buildup and may prevent uniform cutting.
For a professional touch in large open areas, try the mowing pattern in Figure 2. Make two passes counter­clockwise to discharge clippings away from bordering objects. Then cut the lawn in half by mowing down the center. Turn clockwise to the right at end of area over grass previously mowed.
Plan your mowing pattern to travel straight forward whenever possible.
Mowing Tips
Extremely tall grass should be mowed twice. Cut grass higher on first pass. Cut the second time at desired height at 90° to the first pass.
Remember, sharp blades produce cleaner cuts and use less power.
10 Operation
It is better to mow grass more often rather than too short. Short grass deteriorates rapidly in hot weather and invites weed growth during growing seasons. Fol­low local recommendations for the suitable cutting height in your area.
32695 (Rev. 11/17/2006)
Figure 2. Mowing Pattern
BLADES
Mowers are shipped with standard suction blades which are designed for normal mowing conditions.
Optional low suction blades are available for use in sandy areas.
UNEVEN TERRAIN
A WARNING
Be careful when operating tractor and mower
on uneven ground. In extremely uneven terrain, rear wheel weights should be used to improve trac­tion.
The addition of rear tire weights and liquid ballast in rear tires will increase tractor stability.
Pass diagonally through sharp dips and avoid sharp drops to prevent “hanging up” the tractor and mower. Practice will improve your skills in maneuvering rough terrain.
Avoid sudden starts and stops when traveling up or down hill. Always mow down steep slopes, never up or across the face.
Slow down on sharp turns and slopes to prevent tip­ping or loss of control.
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.
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.

OWNER SERVICE
washer (6), blade (5), blade stop (4) and clutch disc (3). Shoulder washer (2) will not normally come off machine unless intentionally removed.
Lower mower to ground, turn tractor engine off
and remove key before performing any mainte­nance.
When completing a maintenance or service
function, make sure all safety shields are in good condition and properly installed before placing mower in service.
A CAUTION
Always use personal protection devices such
as eye and ear protectors when performing mainte­nance functions.
BELT INSTALLATION
See Belt Installation in Assembly section on page 19.
BLADE SERVICING
Blades may be removed from the mower while it is still mounted on the tractor.
A WARNING
If you suspend mower on tractor hydraulic sys-
tem, be sure to install safety blocks. The tractor hydraulic system could fail, causing mower to fall and crush anything under it.
Do not handle mower blades with bare hands.
Careless or improper handling may result in seri­ous injury.
Inspect blades before each use to determine that they are mounted tightly and are in good condition. Replace any blade that is bent, excessively nicked, worn or has any other damage. Small nicks can be ground out when sharpening.
BLADE REMOVAL
See Figure 3. Install blade wrench over spindle pulley bolts to prevent spindle from rotating while removing bolt (10) which has left hand threads. Then remove special washer (9), sleeve (8), cup washers (7), shim
BLADE INSTALLATION
See Figure 3. Assemble shoulder washer (2) small end up (if removed). Install remaining parts in reverse order of disassembly. Ensure blade cutting edge is posi­tioned to lead in counter-clockwise rotation, as viewed from top of mower.
Shims should be added to blade installation to leave approximately 1/32" cup in cup washers when blade bolt is torqued to 170 lbs-ft.
Excessive blade slipping can cause the cup washers to burn and lose their clamping force. If this happens, the cup washers must be replaced.
This blade friction clutch disc allows the assembly to slip when hitting a solid object. If slippage occurs dur­ing normal mowing, it may be necessary to add an additional shim washer (6).
A WARNING
Do not substitute any bolt for the special blade
bolt. It is self-locking, meeting the non-loosening requirements for this application.
Your dealer can supply Woods replacement
blades. They are made of special steel alloys and subjected to rigid heat-treated and inspections requirements. Substitute blades may not meet these rigid specifications and may be dangerous.
BLADE SHARPENING
IMPORTANT
When sharpening blades be sure to balance
them. Unbalanced blades will cause excessive vibration which can damage blade spindle bear­ings. Vibration may also cause structural cracks in mowing housing.
See Figure 4. Follow original sharpening pattern as shown in Figure 4. Do not sharpen blade to a razor edge, but leave a 1/32" to 1/16" blunt edge. Do not sharpen back side of blade.
