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.
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.
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.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
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,

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.

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.
3. Lift channel
4. Tailwheel adj.
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.
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 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.
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".
Shorten the check chains to raise front of cutter. Move
tailwheel adjustment to the rear to raise rear of cutter.

ATTACHING CUTTER TO TRACTOR
(PULL-TYPE MODELS)
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.
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.

PRE-OPERATION CHECK LIST
(Owner’s Responsibility)
___ Check that cutter is properly and securely
attached to tractor.
___ Make sure driveline spring-activated locking pin
slides freely and is seated firmly in tractor PTO
spline groove.
___ On pull-type cutter, make sure the pin to prevent
crank detachment is installed.
___ Set tractor PTO at 540 rpm.
___ Make sure gearbox is full to fill plug with SAE
90W gear lube.
___ Lubricate all grease fitting locations.
___ Check that all hardware is properly installed and
secured.
___ Check to ensure blades are sharp and secure
and cutting edge is positioned to lead in a
counter-clockwise rotation.
___ Check that all shields and guards are properly
installed and in good condition.
___ Check cutting height and attitude adjustment.
___ Place tractor PTO and transmission in neutral
before attempting to start engine.
___ Inspect area to be cut and remove stones,
branches or other hard objects that might be
thrown, causing injury or damage.
___ Inspect chain shielding and replace any damaged
or missing links.
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.
This complete procedure must be followed to properly
set a new cutting height. Raising rear of deck with
crank without changing the compression link position
will result in an incorrect front-to-rear attitude setting.
16 Operation
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
WARNING
WARNING
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. 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
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.
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.
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

BLADE SERVICING (FIGURE 8)
On pull-type units, a pin is installed to prevent
the height adjustment crank from detaching. Do
not operate or service unit unless pin is installed.
Blocking the cutter before working underneath provides
additional safety. If a mechanical or hydraulic failure
occurs, the blocks will support the cutter and prevent
anyone under it from being crushed.
Inspect blades, each time before operating cutter, for
condition and proper installation. Check to be sure
blades are snug but still swivel on blade pin (see Blade
Installation, page 20). Replace any blade that is bent,
excessively nicked, worn or has any other damage.
Small nicks can be ground out when sharpening.
Blade Removal (Figure 8)
Rotate crossbar until blade pin assembly is directly
below access hole in rear of cutter frame. Remove bolt
(1) and blade pin lock clip (2). Slide keyhole plate (3)
out of blade pin groove and remove. Remove spacers
and drive pin out of crossbar.
NOTICE
■ If blade pin is seized in crossbar and extreme
force will be required to remove it, support crossbar from below to prevent damage to spindle.

Figure 9. Belt Routing
Avoid excessive force during installation. Do not use
tools to pry belt into pulley groove. Do not roll belt over
pulleys to install. This can cause hidden damage and
premature belt failure. Always loosen idlers when
installing belts.
Figure 8. Blade Removal & Installation
Blade Installation
Always replace both blades at the same time to maintain balance.
Liberally coat blade pin and crossbar hole with NeverSeez® or equivalent. Make sure blade is offset away
from deck and cutting edge is positioned for counterclockwise rotation.
Install blade pin (9) up through blade (8) then through
hole in crossbar and push firmly against crossbar (7).
Install as many spacers (4, 5 or 6) as possible and still
be able to slide keyhole plate (3), with ears up as
shown, into blade pin groove. Place blade pin clip (2)
over keyhole plate and into blade pin groove. Secure
with bolt (1). Repeat for opposite blade.
Blade should be snug but swivel on pin without excessive force. Retain any spacers not used in installation
for use when blade wears or on future installations.
Blade Sharpening
Always sharpen both blades at the same time to maintain balance. Follow original sharpening pattern. Do not
sharpen blade to a razor edge. Leave from a 1/16" to
1/8" blunt edge. Do not sharpen back side of blade.
Belt Installation (Figure 9)
The drive on this cutter uses three belts. They are a
matched set and must be replaced as such.
Remove belt shields.
Loosen nut on idler adjustment rod (located on right
side of gearbox stand) as loose as possible.
Remove old belts and install new ones. Tighten nut on
idler adjustment rod. Belts should be very tight.
NOTICE
■ Check tension on new belts every half hour the
first four hours of operation and then every eight
hours.
CHAIN SHIELDING
Full chain shielding, designed to reduce the
possibility of thrown objects, must be installed
when operating in populated areas or other areas
where thrown objects could injure people or damage property. If this machine is not equipped with
full chain shielding, operation must be stopped
when anyone comes within 300 feet.
One of the major causes of belt failure is improper
installation.
Before new belts are installed, check pulley shafts and
bearings for wear. Check pulley grooves for cleanliness

The information in this section is written for dealer service personnel. The repair described herein requires
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.
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.)
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.
22 Dealer Service
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.
Inspect gear shafts and sleeves. Pay specific attention
to areas where seals seat. Check for cracks, grooves,

nicks or bumps. If damage cannot be repaired by resurfacing with emery cloth, replace damaged part.
small ends of the teeth on both gears should be flush
with each other and there should be some backlash.
Inspect housings for damage, paying specific attention
where seals seat. Replace housing if damaged area
cannot be resurfaced with emery cloth.
Gearbox Assembly
(Refer to illustration on page 45.)
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
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.
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
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.

NOTICE
■ The gearbox was not filled at the factory. It
must be serviced before operating cutter. Failure to
service will result in damage to the gearbox.
Chain Shielding Installation (Figure 22)
Full chain shielding, designed to reduce the
possibility of thrown objects, must be installed
when operating in populated areas or other areas
where thrown objects could injure people or damage property. If this machine is not equipped with
full chain shielding, operation must be stopped
when anyone comes within 300 feet.
All four chain assemblies (1) are interchangeable.
Place each assembly on the cutter and attach by
inserting bolt (4) up through the cutter and chain shield
assembly, then install flange lock nut (5) on each bolt.
The drag rods (2) are sold separately. To install, place a
lock nut (3) on one end and thread rod (2) through bot-
tom of 16 chain links, then secure with another lock nut
(3). Two rods (2) are used on each chain shield assembly (1).
