SET-UP ASSEMBLY
Driveline Installation
The attachment is shipped completely assembled
with the exception of the driveline. The driveline
must be installed prior to operation for the first time.
1. Position the attachment flat on the ground.
2. Remove both retaining bolts from the driveline.
3. Grease the attachment gearbox input shaft.
4. Align the driveline splines with the gearbox
splines. Slide the driveline onto the input shaft
so that the bolt holes on the driveline are aligned
with the groove on the input shaft.
5. Reinstall and tighten the driveline retaining bolts
to secure the driveline on the input shaft.
6. Connect the driveline safety shield chain to the
hole in the gearbox shield.
NOTE: The driveline may need to be shortened.
When mounting the attachmenton the tractor for the
first time, check the driveline length and shorten if
necessary (see “Instructions for Shortening the
Driveline” on page 9).

8
1. Use the step, safety treads, and grab handles to
get on and off of the tractor.
2. Sitting in the operator’s seat, fasten the seatbelt.
3. Drive the tractor to the front of the attachment.
Align the tractor 3-point arms with the
attachment mounting pins.
4. Stop the engine and engage the park brake.
5. Connect the tractor 3-point links to the
attachment using the pins provided.
6. Compress the quick release pin on the
attachment driveline and align the driveline
splines with the tractor PTO shaft splines. Slide
the driveline onto the PTO shaft. When the
driveline is slid on properly, the quick release pin
will lock itself into place (usually about 1.5” to 2”
onto the PTO shaft).
7. Connect the driveline safety shield chain to the
tractor. Make sure the other end of the chain is
connected to the driveline safety shield.
8. Adjust the 3-point top link for proper deck and
driveline clearance. The driveline and deck
should have approximately 1” of clearance
between them. Refer to the tractor’s operator’s
manual for top link adjustment instructions.
All appropriate hitch pins and PTO
driveline must be locked into place. Failure to
secure PTO shaft or pins can allow the
attachment to disconnect from the tractor and
cause injury or death.
The tractor must be equipped with
a working PTO shield. To avoid serious injury or
death, never adjust or move the driveline when
connected to the tractor and the tractor’s PTO
drive is engaged.
MOUNTING INSTRUCTIONS
After the initial set-up assembly is completed use the following procedure to mount the attachment to the
compact tractor for user operation.

9
The tractor must be equipped with
working PTO shield. Never adjust or move the
driveline when connected to the tractor and the
tractor’s PTO drive is engaged to avoid serious
injury or death.
In some cases it will be necessary to shorten the PTO
driveline to match your specific tractor. Use the
following procedure to shorten the driveline.
1. Raise the 3-point hitch so the attachment gearbox
input shaft is in line with the tractor PTO shaft.
This position is produces the shortest distance
between the gearbox and tractor PTO shafts.
Shut down the tractor, leaving the attachment in
this position. Securely block the attachment in this
position.
2. Pull the driveline apart. Attach the outer (female)
section to the tractor PTO shaft. Make sure the
driveline is locked into place.
3. Hold the driveline sections parallel to each other
to determine if they are too long. Each section
should end approximately 3” short of the universal
joint shield on the opposite section. If the shaft is
too long, measure 3” back from the universal joint
and mark it on the opposite end. Do this to both
ends of the driveline.
IMPORTANT: Do not cut the driveline until steps
4 and 5 have been completed.
4. Remove the blocks from under the attachment.
Raise and lower the attachment to determine the
position with the greatest distance between the
gearbox and tractor PTO shafts. Shut the tractor
off, leaving the attachment in this position.
Securely block the attachment in this position.
INSTRUCTIONS FOR SHORTENING THE DRIVELINE
5. Hold the driveline sections parallel to each other
and check for a minimum 6” of overlap. Overlap
will be the distance between the marks made in
step 3.
6. If the driveline needs to be cut, remove the
marked section of the driveline and shield using a
hack saw.
7. Apply multi-purpose grease to the inside and
outside of both driveline ends and slide them
together.
8. Raise and lower the attachment to check that the
driveline assembly does not jam at any point. If it
does, cut equal amount off of each end, making
sure there is always at least 6” of overlap.
9. Check the full range of intended motion of the
attachment and make sure the swinging drawbar
on the tractor does not contact the driveline at any
point. If necessary, the drawbar can be moved
forward or removed on most tractors (refer to your
tractor’s operator’s manual).

10
The type of brush being cut and the ground
conditions will determine the best ground speed
and cutting procedure. The attachment is designed
to cut short or tall grass, brush, and small saplings.
IMPORTANT: Before operating the attachment,
perform the service schedule for routine
maintenance found on page 13.
1. Inspect the cutting area for obstructions such as
stumps, wire, rocks, electricallines, debris, drop
offs, holes, etc. Remove obstructions from the
cutting area thatmight be picked up and thrown.
Clearly mark any obstructions that cannot be
removed.
2. With the operator in the seat of the tractor and
the seat belt fastened, start the engine.
To improve stability, always
carry the attachment low to the ground while
driving.
3. Use the 3-point arms to lower the mower until
the wheel rests on the ground and the deck is
level.
To avoid serious injury or
death, never engage the tractor PTO drive or
operate the attachment in any position other
than the mowing position.
4. With the engine RPM at an idle, engage the
tractor PTO. Gradually throttle the engine up to
operating RPM.

_____________________ROUTINE MAINTENANCE________________
Lower the attachment to rest flat on the ground, disengage the PTO, set the park brake,
shut down the engine, remove the key, and wait for all motion to stop before leaving the operator’s
seat to perform service of any kind.
It is the operator’s responsibility to make daily inspections of the tractor and attachment for damage, loose
bolts, fluid leaks, or anything else that could cause a potential service or safety problem. Preventive
maintenance is the easiest and least expensive type of maintenance.
IMPORTANT: Bolts and set screws can loosen after initial usage. After the first hour of operation check all
bolts and set screws. Continue to check for loose hardware every 10 hours of operation.
DAILY INSPECTION
Check the following items every 10 hours of operation.
1. Check blades for cracks or damage. Replace if necessary.
2. Check driveline quick release pin and retaining bolts for damage or wear.
3. Check friction clutch for excessive wear (refer to page 14).
4. Check blade mounting hardware for proper torque (1000 ft-lbs., refer to page 15).
5. Check chains, decks, and shields for damage. Repair or replace if necessary.
6. Check for damaged or missing decals. Replace if necessary.
7. Clean debris, leaves, grass, and flammable material from deck.
8. Lubricate all pivot points.
9. Check lubrication level in gearbox (EP80W-90 or EP85W-140 gear lube, approximately 33 oz.).
Use No. 2 lithium base gun grease when
lubricating all the attachment grease fittings.
Grease tail wheel bushing [A] and driveline u-
joints [B] after every 8 hours of operation.
Clean profile of inner tube of driveline, coat with

Gearbox Fluid Check and Fill
Add 80W-90 EP or 85W-140 EP gear lube to
gearbox as needed. Oil capacity is approximately
33 oz.
To check the oil level, position the attachment flat
on the ground, stop the engine, and engage the
park brake. Remove the level check plug [A]. Oil
must be level with the check plug hole. To add oil,
remove the fill plug [B] and add lube until it starts to
come out of the check plug hole. Reinstall the
check plug and the fill plug.
IMPORTANT: Fluids such as engine oil, gear lube,
and hydraulic fluid must be disposed of in an
environmentally safe manner. Some regulations
require that certain spills and leaks be cleaned in a
specific manner. Check local, state, and federal
regulations for correct disposal methods.
Slip Clutch Adjustment
Slip clutch may be hot. Allow
clutch to cool before servicing.
The slip clutch is factory presetto the correct torque
for protecting the attachment and tractor. For
adjustment, use the following steps.
1. Loosen all eight clutch bolts to remove all
tension from the springs.
2. Hold the clutch hub solid and turn the shaft to
make sure the clutch slips. If the clutch does
not slip, disassemble the clutch and clean with
a clutch cleaning solution.
3. Reassemble the clutch once cleaned.
4. Tighten each of the eight bolts until the springs
are all evenly compressed to 1-1/16”.
IMPORTANT: Do not over tighten the clutch
bolts. Over tightening can lead to severe
damage or failure of the attachment.
IMPORTANT: If the clutch continues to slip
excessively when the springs are compressed
to 1-1/16”, check the friction discs for excessive
wear. Discs are 1/8” thick when new. Replace
discs after there is 1/16” wear.
