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 17.
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
