SAFETY
Improper operation can cause serious
injury or death.
Pre-operation
This attachment is designed to be used for mowing
grass, brush, and small saplings only. NEVER use
this machine for any other purpose.
Read the operator’s manual for the “Compact
Tractor”. NEVER allow untrained people to operate.
Operating instructions must be given to everyone
before operating this attachment and at least once a
year thereafter in accordance with OSHA regulations.
NEVER exceed the maximum recommended input
power or speed specifications for the attachment.
Over-powering or over-speeding the attachment may
cause personal injury and/or machine damage.
Keep all shields, guards, and covers in place.
Do not modify equipment or add attachments that are
not approved by Erskine Attachments LLC.
Use adequate safety warning lights and devices as
required by local regulations. Obey all local laws and
regulations regarding machine operation on public
property.
Only use attachment with a tractor equipped with a
Roll Over Protection System (ROPS) and seatbelt.
Operation
Avoid loose fitting clothing. Clothing or hair caught in
moving parts may lead to serious injury or death.
Always wear eye protection that meets ANSI z87.1 or
operate with an enclosure that provides similar
protection.
To protect the operator from hearing loss, ear
protection is required unless the tractor is equipped
with a noise reduction cab that meets OSHA 1910.95
standard.
Operation (continued)
Check andbe sure all operatingcontrols are in neutral
before starting the engine.
Keep people away from tractor, attachment and
discharge when in use. This attachment sends
objects flying and has rotating parts. NEVER direct
discharge toward people –rocks and debris can be
thrown hundreds of feet.
NEVER operate near embankments or terrain that is
so steep that rollover could occur.
Always stay in the operator position with seatbelt
fastened when using the attachment.
Before leaving the operators position, disengage PTO
drive, lower the attachment to rest flat on the ground,
stop engine, set park brake, and wait for all motion to
stop.
NEVER place hands in the discharge area or clear
debris while the engine is running.
Maintenance
NEVER make adjustments, lubricate, clean, or
perform any service on the machine while it is in
operation.
Make sure the attachment is serviced on a daily
basis. Improper maintenance can cause serious
injury or death in addition to damage to the
attachment and/or your equipment.

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.
IMPORTANT: Do not engage or disengage
PTO at full throttle.
IMPORTANT: Do not operate if excessive
vibration is present. Serious damage can
occur. Shut down tractor and check blades and
gearbox.
5. Drive forward into the work area.
