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 12.
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
