SAFETY RULES
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.

IMPORTANT

SHREDDING MATERIAL
For shredding, set the cutter lower at rear. Determine
how much lower to set the rear by experimenting in different situations.

ADJUST CUTTING HEIGHT

WARNING
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
■

Avoid 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.

■

Select a top link mounting pin (maximum
length 3-5/8") that will allow floating link to swing
freely through the cutter A-frame bars.
1. Attach tractor top link (1) to lowest hole provided in
the tractor’s top link bracket (6).
2. Attach rear portion of tractor top link to the first hole
on the cutter floating link (3). Select a top link
mounting pin that will allow the floating link to
swing freely through the cutter A-frame bars (5).
3. Raise cutter to transport position and adjust tractor
top link until cutter is level in the raised position.
NOTE: If you cannot level the cutter using the lowest hole in the tractor’s top link bracket, move top
link to the next hole and level the cutter.

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 mowing.

3. Control cutting height with tractor 3-point arms,
rear tailwheel adjustment, or optional check chains.

The cutting height is the distance between the blade
and the ground. The blades are approximately 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 3", set the center of
the deck 11.5" above the ground:
3" Desired cutting height
+ 8.5" Distance blade cutting edge is below deck
= 11.5"
c) Adjust the front-to-rear attitude from 1/2" to 3/4"
higher than the front.

ADJUST CHECK CHAINS
1. Refer to Install Optional Check Chains, page 33
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.

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.

Figure 5. Check Chain Adjustment

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.

___ Review and follow all safety rules and safety
decal instructions on pages 3 through 7.
___ Check that equipment is properly and securely
attached to tractor.
___ Make sure driveline spring-activated locking
pin or collar slides freely and is seated firmly in
tractor PTO spline groove.
___ Set tractor PTO at 540 rpm.
___ Lubricate all grease fitting locations. Make sure
PTO shaft slip joint is lubricated.
___ Check to be sure gear lube runs out the small
check plug on side of gearbox.
___ Check that all hardware is properly installed
and secured.
___ Check that blades are sharp and secure and
cutting edge is positioned to lead in a counterclockwise rotation.
___ Check that shields and guards are properly
installed and in good condition. Replace if
damaged.

Proper ground speed will depend on the terrain
and the material’s height, type, and density.

___ Check cutting height, front-to-rear attitude, and
top link adjustment.

Normally, ground speed will range from 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.

___ Place tractor PTO and transmission in neutral
before starting engine.

MAN0050 (Rev. 8/19/2005)

___ Inspect area to be cut and remove stones,
branches, or other hard objects that might be
thrown and cause injury or damage.

Operation 11

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

WARNING
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.

CAUTION
If you do not understand any part of this manual
and need assistance, see your dealer.
Always wear relatively tight and belted clothing
to avoid getting caught 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.

BLOCKING METHOD

WARNING
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 system failures,

12 Owner Service

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 1000 lbs. or more
are the only approved blocking device for this
cutter. Install a minimum of four jackstands (shown
by Xs in Figure 5) under the cutter before working
underneath unit.
Do not position jackstands under wheels, axles, or
wheel supports. Components 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.

(Rev. 8/19/2005)
MAN0050 (Rev. 1/16/2004)

LUBRICATION INFORMATION
1. Do not let excess grease collect on or around
parts, particularly when operating in sandy areas.
2. See Figure 5 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

5. 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.

4. 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.

of the six nuts by two full revolutions. The gap
between Belleville spring and thrust plate should
be 1/8" as shown in Figure 8.

6. Turn tractor off and remove key.

8. If a clutch continues to slip when the spring is
compressed to 1/8", check friction discs (2) for
excessive wear. Discs are 1/8" when new. Replace
discs after 1/16" wear. Minimum disc thickness is
1/16".

7. The friction lining plates should have "slipped".
Check the marks placed on the outer plates of the
slip-disc clutch in step 3 to make sure this is the
case.
8. If clutch does not slip check assembly for oil,
grease and debris. Clean if necessary.

(Comer)
1. Turn off tractor engine and remove key.

9. Reassemble clutch and tighten bolts no more than
1/8 of a turn at a time until desired setting of 1.26"
