AFETY RULE
S
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and
manufacture of our products. Unfortunately, our
efforts to provide safe equipment can be wiped
out by an operator’s single careless act.
In addition to the design and configuration of
equipment, hazard control and accident prevention are dependent upon the awareness, concern,
judgement, and proper training of personnel
involved in the operation, transport, maintenance
and storage of equipment.
It has been said “The best safety device is an
informed, careful operator.” We ask you to be that
kind of operator.
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.

Operation 13
Page 14
Driveline Attachment
Attach the cutter to the tractor 3-point hitch (or quick
hitch if available). Do not attach driveline. Raise and
lower cutter to determine maximum and minimum distance between the tractor PTO shaft and the gearbox
input shaft. If the distance is too large, the driveline will
be too short for proper engagement. If distance is too
small, the driveline may bottom out in operation and
damage the cutter or tractor.
Driveline length must be sufficient to provide at least
1/3 driveline length of engagement during operation.
There must be at least 4 inches of engagement at the
cutters lowest possible point of operation. The driveline
must not bottom out when raised to the maximum
height possible.
If driveline is too short please call your Woods dealer
for a longer driveline.
If driveline is too long please follow the instructions for
shortening the driveline.
A
1-9/16"

Shorten Driveline
1. Move cutter up and down to get the shortest
possible distance between tractor PTO shaft and
gearbox input shaft.
2. Separate driveline into two halves and connect
them to the tractor PTO and gearbox.
3. Place driveline halves parallel to one another to
determine how much to shorten the driveline.

WARNING
8. File and clean cut ends of both drive halves.
Do not use tractor if proper driveline engagement cannot be obtained through these methods.
When using optional check chains, install them in keyhole brackets. Count the links between the cutter and
brackets to be sure you have the same number of links
on each side. You may twist check chain for fine adjustment side to side.
Connect driveline to tractor PTO shaft, making sure the
spring-activated locking collar slides freely and locks
driveline to PTO shaft.
NOTICE
■ If attaching with quick hitch the distance
between the tractor PTO and gearbox input shaft
will increase. Please follow the steps as you would
for a 3-point hitch to insure proper engagement.
Cutting Height Adjustment for MD80
Mounted Cutter
Place tractor and cutter on a level surface.
The adjustments given here are to provide you with a
starting point. Adjustments are approximate and may
vary due to slight differences in blade shimming and
machine wear. You may desire to fine tune them for
your situation.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
■ Avoid very low cutting heights. Striking the
ground with blades produces one of the most damaging shock loads a cutter can encounter. Allowing
blades to contact ground repeatedly, will cause
damage to cutter and drive.
Cutting Height Adjustment Without
Tailwheel or Check Chains
The blade is approximately 9-1/4" below the top of the
cutter deck.
Select a cutting height, EXAMPLE 3".
Use tractor 3-point lift to set front blade 3" above level
surface (measure 12-1/4" from top of deck to ground).
At the rear, measure from top of deck to ground; adjust
top link until this distance is from 12-3/4" to 13". Adjust
lower stop of the tractor 3-point lift control. When
adjustment is set, this will enable you to return to the
preset cutting height.
Maintain distance from blade tip to level surface from
1/2" to 3/4" higher at rear for best cutting results and
lowest power consumption.
When using cutter for shredding, it is better to set blade
tip lower at the rear. How much lower depends on the
material to be shredded. You will need to experiment to
determine the best setting for your situation.
Cutting Height Adjustment With Tailwheel
or Check Chains
The blade is approximately 9-1/4" below the top of the
cutter deck.
Select a cutting height, EXAMPLE 3".
Use check chains and tractor 3-point lift and raise top
front of cutter deck 12-1/4" above the level surface. At
the rear, measure from top of deck to ground; adjust
tailwheel until this distance is from 12-3/4" to 13".
Figure 5. Cutting Height Adjustment - MD80
(Mounted Model)
Cutting height may be controlled by several methods.
Without the optional check chains and tailwheel it is
controlled with the tractor 3-point lift and top link adjustment.
Measure from front edge of cutter frame (on each side)
to ground to be sure cutter is level. Use adjustment on
3-point arms, if necessary, for fine adjustment side to
side.
15914 (Rev. 3/23/2007)
Shorten the check chains to raise front of cutter. Move
tailwheel adjustment to the rear to raise rear of cutter.
ATTACHING PULL-TYPE CUTTER TO
TRACTOR
The cutter is shipped with a 1-3/8" PTO spline. The
horizontal distance between the end of the tractor PTO
shaft and the drawbar hitch point should be 14". This
distance must not vary more than plus or minus one
inch (±1") or the drive may be damaged when turning.
Adjust tractor drawbar to obtain the desired drawbar to
hitch point distance. On some tractors, a drawbar kit
must be used to obtain the required dimension. Check
with your tractor dealer if you encounter problems.
Raise cutter tongue to tractor drawbar height with jack
provided and attach with a 3/4" or larger high-strength
drawbar pin. Retain pin to keep it in place.
Operation 15
Page 16
Connect cutter driveline to tractor PTO shaft, making
sure the spring-activated locking pin slides freely and is
seated firmly in tractor PTO spline groove.
Adjust H-frame bearing height to ensure front driveline
is parallel to ground.
Remove parking jack from tongue. Attach to frame rail
storage with top forward. Always attach jack to tongue
to hold it up when disconnecting it from tractor.
Adjust drive shaft carrier bearing (2), Figure 6, vertically in H-frame until driveline is as straight as possible
between tractor PTO and cutter gearbox.
Cutting Height Adjustment for D80 PullType Cutter
Place tractor and cutter on a level surface.
Cutting height is raised and lowered with height adjustment crank (3) or optional hydraulic cylinder. Front to
rear attitude is set with the compression link (1). See
Figure 6.
The blade is approximately 9-1/4" below cutter deck.
Select a cutting height, EXAMPLE 3".

STARTING AND STOPPING CUTTER
Cutter operating power is supplied from tractor PTO.
Refer to your tractor manual for PTO engagement and
disengagement instructions. Always operate PTO at
540 rpm. Know how to stop tractor and cutter quickly in
case of an emergency.
When engaging PTO, the engine rpm should always be
low. Once engaged and ready to start cutting, raise
PTO speed to 540 rpm and maintain throughout cutting
operation.
OPERATING TECHNIQUE
Proper ground speed will depend upon the height, type
and density of material to be cut.
Normally, ground speed will range from 2 to 5 mph. Tall
dense material should be cut at a low speed, while thin
medium-height material can be cut at a higher ground
speed.
Figure 6. Cutting Height Adjustment - D80
(Pull-Type Model)
16 Operation
Always operate PTO at 540 rpm; this is necessary to
maintain proper blade speed and produce a clean cut.

Under certain conditions, tractor tires may roll some
WARNING
WARNING
material down and prevent it from being cut at the
same height as the surrounding area. When this
occurs, reduce tractor ground speed but maintain 540
rpm PTO speed. The lower speed will permit material
to at least partially rebound.
Under some conditions, material will not rebound
enough to be cut evenly, resulting in an uneven
appearance. In general, lower cutting heights give a
more even cut with less tendency to leave tire tracks.
The cutter is equipped with general purpose suction
blades as standard equipment. These blades are
intended for most conditions.
Optional flat blades for light brush cutting and optional
high fin blades for stalk shredding are available from
your dealer.
Tips
Extremely tall material should be cut twice. Cut material higher the first pass. Then cut at desired height, at
90° to first pass.
Remember, sharp blades produce cleaner cuts and
require less power.
Analyze area to be cut to determine best procedure.
Consider height and type of material and terrain type:
hilly, level or rough.
Plan your pattern to travel straight forward whenever
possible.
Inspect and clear area of stones, branches, or
other hard objects that might be thrown, causing
injury or damage.
Uneven Terrain
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.
Pass diagonally through sharp dips and avoid sharp
drops to prevent hanging up tractor and cutter.
Practice will improve your skills in maneuvering rough
terrain.
STORAGE
Follow these steps when storing your cutter:
1. Store on level, solid ground.
2. Disconnect driveline and secure up off the ground.
3. On pull-type model, attach parking jack and raise
tongue weight off tractor drawbar.
4. Securely block all four corners of deck with jack
stands.
5. Remove hydraulic hoses after tractor is turned off
and all system pressure is released by operating
valve levers several times.
6. Remove retainer pin and high strength drawbar
pin.
7. Keep children and bystanders away from storage
area.

special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in
this type of repair, you may be time and money ahead
to replace complete assemblies.
GEARBOX MAINTENANCE
Before beginning any gearbox repair, please read this
entire section. Many steps are dependent on each
other.
Always make sure proper vent plug is installed in top of
gearbox. Proper gear lube level for gearbox is half full.
Never operate cutter unless gearbox is half full of SAE
90W gear lube.
Troubleshooting is an important part of gearbox maintenance. Check for leakage and bad bearings.
Bearing Check
Bearing maladjustment or failure is indicated by excessive noise and noticeable side or end play in gear
shafts.
Possible Leakage Causes
Leakage may be caused by an improperly operating
vent plug. The plug has a check valve in it; remove and
apply very low pressure air to the bottom to check for
proper venting.
Check housing for visible signs of leakage.
Check for leaks at vertical and horizontal seals and
gaskets.
Take necessary corrective action and clean area where
leakage was evident. Place cutter in service and check
to ensure leakage has stopped.
Leakage Repair
Permatex Aviation 3D Form-A-Gasket® or equivalent
is the recommended sealant for gearbox repair.
Leakage at the horizontal seal or gasket can be corrected without removing gearbox from cutter.
Remove fill plug and siphon gear lube from gearbox.
Remove and replace leaking seal or gasket. Refer to
Seal Installation section, page 23.
Removing Gearbox from Cutter
Remove nut from belt tension idler adjustment rod.
Remove belt shields. Remove belts.
The front gear stand bolts are tack welded in place.
Loosen the nuts to protect bolt threads and break tack
welds by rapping them with a hammer. Remove nuts
and bolts.
Remove nuts from the rear gear stand bolts. Tip rear of
gear stand up over bolts and slide the stand rearward.
Cut the safety wire and remove bolt from drive pulley
under gearbox.
Disassemble split taper bushing (located on bottom of
drive pulley) by removing the three bolts and inserting
two of them into the threaded holes. Tighten alternately
to press bushing off.
Remove the four gearbox attaching bolts from the gear
stand and remove gearbox from stand.
Gearbox Disassembly
(Refer to illustration on page 45.)
Remove the horizontal and vertical gear shaft housings
from gearbox housing. Remove seals. Remove tack
weld, holding sleeve to shaft, by grinding. Press gear
and shaft from housing. Remove cups from housing.
Damage Inspection
Inspect gears for excessive wear. Some wear is normal. Gears will show more wear on loaded side. They
are forged and surfaces will appear rough, even when
new. The wear pattern should be smooth.
Do not replace gears unless deep gouges, chips, deep
pitting or deep wear grooves are present.

Bearing cups, cones and sleeves are a press fit.
Press new bearing cups into vertical and horizontal
housings.
Press bearing cones onto vertical and horizontal shafts
until they seat against machined surface next to gears.
Insert shafts into their respective housings and press
bearing cones onto shaft until all free play is removed
(similar to adjusting front wheel bearings on an automobile).
Check adjustment by spinning housing. It should turn
freely. If bearings are too tight, hold housing and rap
gear shaft with lead or brass hammer. Readjust bearings. Proper bearing adjustment is essential to good
bearing life. Do not leave bearings adjusted too tight.
Bearings should turn freely without any noticeable end
play.
Place O-ring seal over shaft and seat against bearing.
Press sleeve on shaft and down against bearing, but
do not move bearing. Check bearing adjustment again
by spinning housing. Readjust if necessary. Protect
surfaces where seal seats and tack weld sleeve to
shaft.
Seal Installation
Gearbox Adjustment
Place a 1/32" thick gasket between the vertical and
horizontal housing and gearbox housing. Horizontal
housing must be positioned so breather hole is at top
when gearbox is on cutter. Snug bolts and check gear
mesh by shining a flashlight into the oil fill hole. The
small ends of the teeth on both gears should be flush
with each other and there should be some backlash.
If the gear teeth are not aligned, add gaskets under
one of the gear housings until they do.
Use a feeler gauge to check for .020 backlash between
the teeth. Adjust by adding or subtracting even numbers of gaskets of the same thickness from each housing and the gearbox.
When all of the bolts are tightened, check the backlash
again to ensure it did not change. If it is changed, add
or subtract gaskets as necessary to obtain .020 backlash between the teeth.
BLADE SPINDLE REPAIR
Remove blades from crossbar and belts from pulley.
Remove split taper bushing from pulley and remove
pulley from spindle. Remove spindle from cutter.
Remove set screw and flanged nut (1) from spindle,
see Figure 11. Block under washer (9) and housing and
press blade carrier and spindle shaft out of housing.
Assembly
Press new cups (6) into spindle housing, seating them
against housing bore shoulder, see Figure 11.
Place bottom end of spindle housing (18) up. Set bearing cone and sleeve (5) on cup.
Coat area of spindle housing where seal seats with
Permatex. Press seal (4) (with spring-loaded lip toward
the center) into housing, using care to prevent seal
cage distortion.
An improperly installed seal will leak and could result in
gearbox failure.
Clean area in housing where outer diameter of seal
seats and apply a thin coat of Permatex.
Lubricate seal lip, position spring toward housing, and
carefully guide over sleeve and shaft, using a blunt tool
such as a letter opener. Use care to prevent seal lip
from rolling under. Do not use a knife blade as it will
nick and ruin seal.
Select a piece of pipe or tubing with an OD that will set
on outside edge of seal cage but will clear housing. A
driver that is too small will bow cage and ruin seal.
Carefully press seal into housing, preventing distortion
to metal seal cage. Seat seal firmly against housing.
