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, judge-
ment, 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.

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 dis-
tance is too large, the driveline will be too short for proper engagement. If dis-
tance is too small, the driveline may bottom out in operation and damage the
cutter or tractor.
The driveline length must be sufficient to provide at least 1/3 driveline length of
engagement during operation. There must be at least 101.6 mm (4 inches) of
engagement at the cutter’s 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.
SHORTENING 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.

Do not use tractor if proper driveline engagement cannot be obtained through
these methods.
Connect driveline to tractor PTO shaft, making sure the spring-activated lock-
ing 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.
DRIVELINE INTERFERENCE CHECK
1.
Check for clearance between driveline and cutter deck.
2.
Slowly lift cutter and observe driveline. If clearance between driveline and
cutter deck is less than 25.4 mm (1 inch), shorten top link or limit upper
travel of lower hitch arms. Refer to tractor operator's manual for
instructions.
CUTTING HEIGHT ADJUSTMENT
Keep all persons away from operator control area while performing
adjustments, service, or maintenance.
■
Avoid low cutting heights. Striking the ground with blades pro-
duces one of the most damaging shock loads a cutter can encounter.
Allowing blades to contact ground repeatedly will cause damage to cutter
and drive.
1.
Level cutter from side to side. Check by measuring from cutter frame to
the ground at each deck rail.
2.
Adjust, using tractor 3-point arm leveling device.
NOTE:
Keep the front of cutter slightly lower than rear for best mow-
ing.
3.
Control cutting height with tractor 3-point arms, rear tailwheel adjustment,
or optional check chains.
4.
To raise rear of cutter, move tailwheel arm down.
5.
To raise front of cutter, raise tractor 3-point arms or shorten optional
check chains.
The cutting height is the distance between the blade and the ground. The
blades are approximately 215.9 mm (8.5") below the deck. To check cutting
height, do the following:
a)
Place a straight edge along top edge of deck.
b)
Select a cutting height; as an example, for an approximate cutting height
of 76.2 mm (3"), set the center of the deck 292.1 mm (11.5") above the
ground:
c)
Adjust the front-to-rear attitude from 12.7 to 19.05 mm (1/2 to 3/4") higher
than the front.
6.
Adjust top link (BB60XE, BB72XE, BB84XE) to provide 50.8 mm (2") of
clearance between break link (2) and rear lift links. See Figure 10. The
clearance will allow cutter to float over uneven terrain.
SHREDDING MATERIAL
For shredding, set the cutter lower at rear. Determine how much lower to set
the rear by experimenting in different situations
.

CHECK CHAIN ADJUSTMENT
1.
Refer to Install Optional Check Chains, page 28 for check chain
installation.
2.
After making cutting height adjustment, adjust both chains (3) in check
chain bracket (2) so you have the same number of links on each side.
This will keep cutting level.

OPERATING TECHNIQUE
1.
Power for operating the cutter is supplied by the tractor PTO. Operate
PTO at 540 rpm. Know how to stop the tractor and cutter quickly in an
emergency.
2.
Engage PTO at a low engine rpm to minimize stress on the drive system
and gearbox. With PTO engaged, raise PTO speed to 540 rpm and
maintain throughout cutting operation.
Gearbox protection is provided by a slip clutch with replacement fiber
disc or a shear bolt. The slip clutch is designed to slip and the shear bolt
will shear when excessive torsion loads occur.
3.
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 3.22 to 8.05 kph (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.
4.
Always operate tractor PTO at 540 rpm to maintain proper blade speed
and to produce a clean cut.
5.
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.
STORAGE
Disconnect cutter driveshaft and secure up off ground. Raise cutter
with 3-point hitch. Place blocks under cutter side skids. Lower cutter
onto blocks. Disconnect cutter from tractor 3-point hitch and carefully
drive tractor away from cutter.
Keep children and bystanders away from storage area.
PRE-OPERATION CHECK LIST
OWNER’S RESPONSIBILITY

Owner Service 13
MAN1254 (3/16/2018)
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.
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 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.
BLOCKING METHOD
Before performing any service or maintenance, 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.
To minimize the potential hazards of working underneath the cutter, follow
these procedures:
1.
Jackstands with a load rating of 453.6 kg (1000 lbs) or more are the only
approved blocking device for this cutter. Install a minimum of four
jackstands (shown by Xs in Figure 12) under the cutter before working
underneath unit.
Do not position jackstands under wheels, axles, or wheel supports. Com-
ponents can rotate and cause cutter to fall.
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 INFORMATION
1.
Do not let excess grease collect on or around parts, particularly when
operating in sandy areas.
2.
See Figure 12 for lubrication points and frequency of lubrication based on
normal operating conditions. Severe or unusual conditions may require
more frequent lubrication.
3.
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
1.
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.
2.
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.
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

replacements 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 gear-
box bearings. Vibration may also cause structural cracks to cut-
ter.
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 1.59 mm (1/16")
blunt edge.
3.
Do not sharpen back side of blade.

DEALER SERVICE
The information in this section is written for dealer service personnel. The
repair described here requires special skills and tools. If your shop is not prop-
erly equipped or your mechanics are not properly trained in this type of repair,
you may be time and money ahead to replace complete assemblies.
Before working underneath, disconnect driveline, raise cutter, lock in
transport position, and block cutter securely. Hydraulic system leak
down and failure of mechanical or hydraulic system can cause equip-
ment to drop.
Keep all persons away from operator control area while performing
adjustments, service, or maintenance.
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.
GEARBOX MAINTENANCE
NOTE: Read this entire section before starting any repair. Many steps are
dependent on each other.
1.
Fill gearbox with SAE 80W or 90W gear lube until it runs out the side
level plug.
NOTE:
Repair to this gearbox is limited to replacing bearings, seals,
and gaskets. Replacing gears, shafts, and a housing is not cost effective.
Purchasing a complete gearbox is more economical.
2.
Inspect gearbox for leakage and bad bearings. Leakage is a very serious
problem and must be corrected immediately. Bearing failure is indicated
by excessive noise and side-to-side or end-play in gear shafts.
Seal Replacement
Recommended sealant for gearbox repair is Permatex
®
Aviation 3D Form-A-
Gasket or equivalent.
Leakage can occur at the vertical or horizontal gaskets and shaft seals.
Leakage at the horizontal gasket or seal can be repaired without removing the
gearbox from the cutter.
Seal Installation
NOTE: Proper seal installation is important. An improperly installed seal will
leak.
1.
Clean area in housing where seal outer diameter (OD) seats. Apply a thin
coat of Permatex.
2.
Inspect area of shaft where seal seats. Remove any burrs or nicks with
an emery cloth.
3.
Lubricate gear shaft and seal lips.
4.
Place seal squarely on housing, spring-loaded lip toward housing. Select
a piece of pipe or tubing with an OD that will sit on the outside edge of the
seal but will clear the housing. Tubing with an OD that is too small will
bow seal cage and ruin seal.
5.
Carefully press seal into housing, avoiding distortion to the metal seal
cage.
Figure 17.
Seal Installation
Vertical Shaft Repair (Figure 18)
1.
Disconnect and remove the rear driveline from the gearbox.
2.
Remove vent plug (27) and siphon gear lube from housing through this
opening.
3.
Remove crossbar (see Crossbar Removal, page 19).
4.
Remove vertical shaft seal (21). Replace with new seal (see Seal
Installation, page 17).
Vertical seal should be recessed in housing. Horizontal seal should be
pressed flush with outside of housing.
NOTE:
Distortion to seal cage or damage to seal lip will cause seal to
leak.
5.
Fill gearbox with SAE 80W or 90W gear lube until it runs out the level
plug.
6.
Remove and replace any seal damaged in installation.
Horizontal Leak Repair (Figure 18)
1.
Disconnect and remove the rear driveline from the gearbox.
2.
Remove vent plug (27) and siphon gear lube from housing through this

While holding gear (1) in place, slide input shaft (3) through gear (1) and
bearing (8). Align splines on shaft (3) and gear (1).
12.
Slide spacer (14) over input shaft (3) and press bearing onto input shaft
(3), using a round tube of the correct diameter and a hand press.
13.
Slide shim (15) over input shaft (3) and secure with snap ring (12).
14.
Check input shaft end float by moving the input shaft (3) by hand. If end
float is higher than .305 mm (0.012"), insert shim between input shaft (3)
and rear bearing (8). Repeat until end float is less than .305 mm (0.012").
Check rotational torque by hand. The torque should be less than .749 N-
m (2.2 lbs-inch).
15.
Check that the gear backlash is between .152 and .406 mm (0.006 and
0.016"). You should not have to adjust the backlash.
