ASSEMBLY
OM 0277-A 10
IMPORTANT:
A proper initial installation will give you years of
satisfactory service on your equipment. Please
read carefully following instructions that have
been specially included to help you and ensure
you are satisfied with your purchase.
WARNING: Unfortunately, snowblowers
will be faced with forgotten or hidden
objects under the snow, such as : chain,
tires, stones, pieces of wood, etc. In spite
of all our efforts, machines are not built to
resist all those conditions.
Danger: Tractors Too Big
It is dangerous to use a tractor that is too big
and powerful. The tractor will always be able to
overload the blower, even if the machine is
already at maximum capacity. Furthermore,
tractors being very high, the driveline angles will
be excessive which means the universal joints
will be very vulnerable and the life of the
driveline will be dramatically reduced.
How to Determine Driveline Angles
IMPORTANT: To obtain the proper universal
joint angles, it is recommended to adjust the
three point hitch at the furthest point from the
tractor recommended by the manufacturer
The universal joint angle is directly related with
the life of driveline. In order to reduce the angle,
it is necessary to increase the distance between
the snowblower and the tractor.
Angles of Driveline Joints Too Large
Avoid
Reasonable Angles of Driveline Joints
Acceptable

ASSEMBLY
OM 0277-A 11
Unequal Angles at Driveline Joints
Avoid
Equal Angles at Driveline Joints
Recommended
Angles at Each End of Driveline
A popular habit is to change the snowblower
angle in order to obtain a better scraping
effect. This practice can become harmful to the
driveline since the angle at each end is
unequal. This results in a fan speed variation
as well as a drastic increase of load on cross
and bearings. To be avoided: It is
recommended to always keep tractor driveline
and snowblower input shaft parallel.
Determining Driveline Length
IMPORTANT: Before using the equipment,
make sure the driveline is not too long. At
working position, the two half drivelines must
intersect each other sufficiently to insure
maximum efficiency but there must not be any
interference.
1. To determine the "L" length for your tractor
model first find the "X" factor by measuring
the horizontal distance between the end of
the tractor's drive shaft and the end of the
snowblower's driven shaft when the
snowblower is in transport position as shown
on Figure 3.
2. Choose in the table below the "Y" factor
according to the tractor category and deduct
that number from "X" to determine "L"
which is the center-to-center length between
the universal joints.
L = X – Y

NOTE: Before cutting, make sure the two shafts
intersect by at least 7 3/4" when in working
position that is when the snowblower rests on the
ground.
3. Hold the two half-shaft side by side and locate
the "L" length between the two center-to-
center half-shaft universal joints. Mark off the
zone to be cut on both halves opposite each
half-shaft guard as shown on Figure 4
4. Cut off inner and outer guard tubes as well as
the inner and outer telescopic sections.
5. Cut the guard a second time leaving the
same distance between the end of the guard
and the end of the shaft as existed before.
To obtain the proper distance "A" shown on
Figure 5, cut the guard according to the
following table:
DISTANCE A
Male PTO Female PTO
1 3/4" 1 1/4"
6. File down tubes and remove chips.
7. Apply grease to inside of outer telescopic
section.
IMPORTANT: Work with fully guarded shafts
only!

Removing the Snowblower from Tractor (Figure 6)
1. Set snowblower completely on the ground to
release all pressure from the three-point. Set
parking brake and turn engine off.
2. Detach upper link by removing linchpin and
pin (items 4).
3. Disconnect driveline from tractor P.T.O. shaft
and set driveline on support chain.
4. Carefully detach lower links (items 1) by
removing linchpins (items 2) and loosen anti-
sway turnbuckles.
IMPORTANT: To avoid damage to the
snowblower, retorque all bolts after the first
10 hours of operation.

OPERATION
OM 0277-A 14
GENERAL PREPARATION
1. Read the operator’s manual carefully before
using the tractor and snowblower. Be
thoroughly familiar with the controls and
proper use of the equipment. Know how to
stop the unit and disengage the controls
quickly.
2. Make sure the snowblower is clear of snow
before engaging the driveline.
3. Make sure the auger and fan operate freely.
4. Check the oil level in the worm gear box and
if necessary, add 80W90 SAE gear oil,
AGMA 5EP oil or equivalent.
5. Check the two shear bolts, one on the driving
shaft, and the one on the PTO, for proper
tightness.
6. Adjust so that the snowblower skid shoes run
level.
7. Wear adequate winter outer garments while
operating equipment.
OPERATING CONTROLS
Work and Travel Speed
Working ground speed will depend on the depth
and density of the snow to be cleared. Normally,
ground speed will range from 4 to 7 MPH for light,
dry snowfalls 3 to 6 inches, and 1 to 3 MPH for
heavy, wet or drifted snow. To transport,
disengage the drive shaft and raise the
snowblower to full transport height.
Raising and Lowering the Snowblower
Move the three point lever on right hand side of
seat down or forward to lower, and up or
rearward to raise.
Drive Shaft Operation
The mid drive shaft is activated by pulling up the
drive shaft lever on left side of seat. Push down
to disengage.
WARNING: To avoid personal injury,
be sure the tractor engine is off, the drive
shaft disengaged, and all movement has
stopped before making any adjustments.
Reduction Chain Tension Adjustment
The premature wear of the chain may be caused
by tension being too tight. It is therefore important
not to tighten chain to its maximum.
• To adjust the tension on the drive chain,
loosen the bolt (item 1), securing the idler
sprocket to the snowblower housing.
• To tighten the chain, lower the bolt. Leave
approximately 1/8" deflection in one span of
the chain. Retighten securely the bolt holding
the idler sprocket.
Skid Shoe Adjustment
Adjust the skid shoes so that the snowblower
runs level and according to the surface conditions
so that stones are not thrown with the snow.
Adjust both skid shoes to the same height to
keep the cutting edge level and adjust upwards
for smooth surfaces.
Loosen skid shoe bolts (item 2) and adjust
according to instructions below, and securely
tighten bolts:
Clearance between cutting edge and surface:
•
Level paved surface : Adjust to 1/16" to 1/8"
•
Uneven or gravel surface: Adjust to 1/2" to 5/8"
Manual Deflector Adjustment
Set the deflector angle according to the distance
the snow must be thrown. To set the angle,
remove the adjusting pipe 1/4" round wire lock
pin and set the adjusting rod to the desired
deflector angle. Secure with the round wire lock
pin.

OPERATION
OM 0277-A 15
SNOW REMOVAL METHODS
When removing snow, do not use the snowblower as a dozer blade to push snow. Let the snowblower
work its way through deep drifts. If the speed of your tractor is too fast, the snowblower may become
overloaded and clog. For best results, raise the snowblower and remove a top layer of snow. A second
pass with the snowblower will remove the remaining snow.
IMPORTANT : Use full RPM power when removing wet, sticky snow. Low RPM power will tend to clog
the chute.
WARNING: Do not use hands or feet to unclog chute. Do not attempt to clear clogged chute of
snow while tractor engine is running. If the chute clogs, disengage the drive shaft, shut off the tractor
engine, remove the ignition key, wait for all movement to stop, and then clear the snow from the chute.
A definite pattern of operation is required to thoroughly clean the snow area. These patterns will avoid
throwing snow in unwanted places as well as eliminating a second removal of snow
Where it is possible to throw the snow to the left
and right (above), as on a long driveway, it is
advantageous to start in the middle. Plow from
one end to the other, throwing snow to both sides
without changing the direction of the discharge
guide
If the snow can only be thrown to one side of the
driveway or sidewalk (above), start on the
opposite side. At the end of the first pass, rotate
the discharge guide 180 degrees for the return
pass. At the end of each succeeding pass, rotate
the discharge guide 180 degrees to maintain
direction of throw in the same area.

MAINTENANCE
OM 0277-A 16
