SET-UP ASSEMBLY
Manual Rotation Discharge Chute Installation
1. Bolt the hand crank support bracket to the upper
arm, and insert the crank tube. Bolt the lower end
of the crank tube to the spool. The crank handle
length is adjustable. Start with the crank in the
shortest position until the snowblower is mounted
to the tractor for the first time.
IMPORTANT: Make sure the crank handle will
not contact the operator or any part of the tractor
through the entire range of motion.
2. Remove one of the roller guides from the
snowblower housing by removing the bolt
securing the roller guide.
3. After unpacking the chute, slip the chute into the
grooves on the two remaining roller guides.
4. Reinstall the roller guide and bushing with bolt and
lock nut.
IMPORTANT: Tighten each roller guide lock nut
to 75 ft.-lbs.
5. Rotate the chute so it is facing the front right
corner of the snowblower body (as viewed seated
in the tractor, facing forward).
6. Feed one end of the cable through the rear hole
of the spool, through the cable guide link, and
around the back of the chute as shown. Tighten
the set screw to lock the cable in place, leaving a
short tail sticking out.
7. Run the cable backwards through the chain links
in such a way that the cable will bind when
tightened. Method can vary, as long as the cable
binds tightly to the chute when tightened.
8. Thread the cable back through the cable guide.

8
SET-UP ASSEMBLY
9. Turn the crank handle clockwise to wind up the
cable on the lower part of the spool. Keep tension
on the loose end of the cable while cranking so
that the cable on the spool doesn’t unwind. Stop
cranking when the chute faces the front left corner
of the snowblower body. The chute should rotate
clockwise, as viewed from above, to reach this
position. The position of the chute does not need
to be exact, andcan be varied to help with the next
step.
10. Thread the remaining end of the cable through the
spool. The ends of the cable should be facing in
opposite directions. The crank position can be
changed slightly to aid in threading the cable and
tightening the set screw. Make sure the cable on
the spool remains tight. Pull all the slack out of
the cable before tightening the set screw.
11. Trim the cable ends as required.

9
SET-UP ASSEMBLY
Hydraulic Rotation Discharge Chute Installation
1. Remove one of the roller guides from the
snowblower housing by removing the bolt
securing the roller guide.
2. Remove the chain cover from the snowblower
housing by removing the two bolts securing the
cover.
3. After unpacking the chute, slip the chute into the
grooves on the two remaining chute guides.
4. Reinstall the roller guide and bushing with bolt and
lock nut.
IMPORTANT: Tighten each roller guide lock nut
to 75 ft.-lbs.
5. Rotate the chute to the straightforward position.
6. Loosen themotor mount bolts, and push the motor
all the way toward the chute.
7. Install the No. 40 roller chain around the motor
sprocket.
8. Pull the motor away from the chute until all slack
is removed from the roller chain, and tighten the
motor mount bolts to secure the motor in place.
IMPORTANT: Do not overtighten roller chains.
Tighten only enough to remove slack.
9. Reinstall the chain cover and two bolts.
Do not operate the
snowblower without the chain shield in
place. Moving parts may cause injury or
death. Always replace guard after servicing.

10
SET-UP ASSEMBLY
Mounting and Adjusting the Snowblower
1. Install the splined yoke of the driveline on the
snowblower gearbox shaft. This end of the
driveline is secured with a sliding lock collar like
the tractor end. Pull back on the collar and push
the yoke onto the gearbox shaft. Release the
collar and make sure it is securely locked in place
on the shaft.
Make sure the PTO master
shield is secured in its operating position.
Never operate the snowblower with missing
PTO shield.
2. The mounting arms are designed to be used on
the standard Category I 3-point hitch. They are
also quick hitch compatible. Be sure to pay extra
attention to the driveline length when using the
snowblower with a quick hitch. Make sure there
is proper engagement throughout the entire range
of motion.
3. Mount the snowblower to the tractor (see
“Mounting Instructions” on pages 13-14).
4. The snowblower may need to be tilted rearward
somewhat in order to create a straighter driveline
angle from the tractor PTO shaft to the
snowblower gearbox. This can be accomplished
by lengthening the tractor’s 3-point top link (refer
to the tractor’s operator’s manual for top link
adjustment instructions). The degree of backward
tilt depends on the tractor size and PTO location.
Example: The higher the tractor PTO shaft is
above the ground, the more snowblower
backward tilt is required.
IMPORTANT: It is extremely important to keep
the driveline angle as straight as possible while
the snowblower is under load, as this reduces
heat buildup and the chance of bearing failure in
the driveline U-joints.

11
SET-UP ASSEMBLY
5. After the snowblower backward tilt is determined
and set, the driveline telescoping length must be
checked.
6. With the snowblower resting on the ground,
connect the driveline to the tractor PTO shaft and
mark the location of overlap on the driveline.
Check to make sure that there is sufficient
clearance between the driveline and the tractor
drawbar. If there is not enough clearance, refer to
the tractor’s operator’s manual for instructions on
shortening or removing the tractor drawbar.
7. Disconnect the driveline from the tractor PTO
shaft and slide the two driveline halves apart.
Using the mark on the shield as a reference,
check to be sure there is at least 5” of overlap
between the driveline shaft and the slide. If there
is less than 5” of overlap, contact your dealer.
8. Start the tractor and carefully raise the 3-point
arms to lift the snowblower to the transport
position. Align the two halves of the driveline with
each other, and the yoke of the outer driveline half
with the tractor PTO shaft to make sure that the
driveline will not bottom out in the fully raised
position.
IMPORTANT: Severe damage to the tractor may
occur if the driveline bottoms out while raising the
snowblower. If the driveline bottoms out, it may
be necessary to use a 3-point quick hitch to move
the snowblower rearward.
9. Once certain that the driveline will telescope
properly, lower the snowblower to the ground,
reassemble the driveline, and reconnect the
driveline to the tractor PTO shaft.
10. Connect the chute rotator hoses (if snowblower is
equipped with hydraulic chute rotation option) to
the tractor’s remote hydraulic couplers. Make
sure the hoses are routed so that they will not
catch on any part of the tractor or snowblower or
contact anymoving partsduring operation. Check
hose routing through the full range of intended
motion before operating the snowblower.
IMPORTANT: Hose routing is the responsibility
of the owner and/or operator. Pinched or
stretched hoses are not covered under warranty.

12
SET-UP ASSEMBLY
11. With the operator in the seat of the tractor and the
seat belt fastened, start the engine. With the
engine at an idle, check that the hydraulic
functions are working properly by rotating the
chute all the way in both directions.
12. With the engine at an idle, engage the tractor PTO
drive to start the snowblower turning. Slowly
increase the engine speed to working RPM. If
there is any excessive vibration or noise while
running the snowblower, throttle the engine down
to an idle, disengage thePTO drive, shut down the
engine, engage the park brake, and wait for all
motion to stop, then exit the tractor and inspect the
snowblower for the cause of the vibration or noise.
Adjust or replace parts as needed.
IMPORTANT: Do not engage or disengage the
PTO drive at full throttle.
13. Set-up assembly is now complete, and the
snowblower is ready for operation. See the
“Mounting Instructions” and “Operating
Instructions” sections of this manual for proper
mounting and operating techniques.

13
MOUNTING INSTRUCTIONS
After the initial set-up is complete, use the following instructions to mount the snowblower to the tractor.
1. With the operator in the seat of the tractor and the
seat belt fastened, start the engine. Drive the
tractor to the front of the snowblower and align the
3-point arms with the snowblower mounting pins.
Stop the engine and engage the park brake.
2. Slide the tug arms over the lower lift pins and
secure with lynch pins. Install the top link pin and
secure with lynch pin.
3. Connect the snowblower driveline to the tractor
PTO shaft. Be sure that the retaining pin snaps
into position on the PTO shaft.
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.
IMPORTANT: Maximum driveline extension is 9”
for the 54” and 60” models, and 17” for the 72” and
84” models. This allows for a minimum overlap of
5”. Extending beyond these lengths could allow
the driveline to separate and lead to equipment
damage. Also check to make sure the driveline
does not bottom out when raising the snowblower,
or severe damage to the tractor may occur.

14
MOUNTING INSTRUCTIONS
4. If the snowblower is equipped with the hydraulic
chute rotation option, connect the snowblower
chute rotation hoses to the tractor’s remote
hydraulic couplers (see the tractor’s operator’s
manual for remote hydraulic coupler locations and
connection instructions). Make sure hoses are
routed so that they will not catch on any part of the
tractor or snowblower or contact any moving parts
during operation. Check hose routing through the
full range of intended motion before operating the
snowblower.
IMPORTANT: Wipe the ends of the hydraulic
couplers (both lead and tractor) with a rag to
remove any possible contamination.
Contamination can cause hydraulic components
to fail and is not covered under warranty.
IMPORTANT: Hose routing is the responsibility
of the owner and/or operator. Pinched or
stretched hoses are not covered under warranty.
5. Mounting is now complete, and the snowblower is
ready for operation. Use the reverse order of
these instructions to dismount the snowblower
from the tractor.

15
OPERATING INSTRUCTIONS
Know your work area. Avoid
obstructions and debris.
1. Before starting the tractor engine, check to see
that the snowblower is nearly level to the ground.
This creates a straighter driveline angle and can
be accomplished by adjusting the length of the
tractor’s 3-point top link (refer to the tractor’s
operator’s manual for top link adjustment
instructions).
NOTE: The snowblower can be tilted rearward in
varying degrees depending on tractor size and
PTO shaft location.
IMPORTANT: It is extremely important to keep
the driveline angle as straight as possible while
the snowblower is under load, as this reduces
heat buildup and the chance of bearing failure in
the driveline U-joints.
2. The skid shoes are fixed and non-adjustable. To
engage the skid shoes with the ground and
minimize the scraping action of the cutting edge,
roll the snowblower toward the tractor slightly by
shortening the tractor’s 3-point top link (refer to
tractor’s operator’s manual). To disengage the
skid shoes and make the cutting edge scrape
more, lengthen the tractor’s 3-point top link.
3. Adjust the chute to control snow discharge angle
and distance. To adjust: remove the pin from the
bottom of the deflector link, move the deflector to
the desired angle, and reinstall the pin through the
chute and deflector link.
NOTE: If the snowblower is equipped with
hydraulic chute deflection, the tractor remote
hydraulic control lever is used to adjust the
deflection angle.
NOTE: Snowblower will achieve maximum
casting distance with the deflector in the highest
position (as shown).

16
4. With the operator in the operator’s position, check
to be sure all operating controls are in neutral and
start the engine.
Keep people at least 100 feet
away from the tractor, snowblower, 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.
5. With the engine idling, check the hydraulic remote
functions for the snowblower discharge chute
rotator (if optional hydraulic rotation is equipped).
6. Rotate the chute toward a clear area.
7. Lower the snowblower to rest on the skid shoes.
8. With the engineat an idle, engage thetractorPTO
drive (see tractor’s operator’s manual).
IMPORTANT: Do not engage or disengage the
PTO drive at full throttle.
9. Increase the tractor engine speed to full throttle.
Always operatethe snowblower with the engine at
full throttle for maximum efficiency.
10. Select the lowest tractor reverse gear, and slowly
drive the tractor backward into the snow. Blow
snow toward a clear area. When possible, direct
snow discharge downwind.
IMPORTANT: Do not operate the snowblower if
excessive vibration is present. Serious damage
can occur. Check auger and fan.
NOTE: The tractor backward speed can be varied
according to snow depth and density. Always
operate the attachment with the loader engine at
full throttle for maximum snowblower efficiency.
NOTE: If the surface to be cleared has very
dense or compacted snow, the snowblower
should be resting on the skid shoes during
operation, with the 3-point arms fully lowered.
This will allow the snowblower to float along the
contour of the ground. If operating in soft snow
conditions, the snowblower can be carried slightly
above the ground with the 3-point arms to
minimize gouging.
