PREPARATION OF THE DRIVELINE
Recommendations for Driveline Angles
IMPORTANT: To obtain the proper universal
joint angles, it is recommended to adjust the
3-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. 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
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 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.

ASSEMBLY
[

Determining Driveline Length
IMPORTANT: Before using the equipment,
make sure the driveline is not too long. At
working, the two half drivelines must intersect
each other sufficiently to insure maximum
efficiency but there must not be any
interference.
1. Figure 4: 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 in figure.
2. Choose in the table below the "Y" factor
according to the driveline series and deduct
that number from "X" measured previously
to determine "L" (fig.7) which is the center-
to-center length between the universal
joints.
NOTE : The driveline series is inscribed on the
plastics guards.

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 in figure.
4. Figure 5A: Cut off inner and outer guard
tubes as well as the inner and outer
telescopic sections.
5. Figure 5A: 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 in figure, cut the guard
according to the following table:
