Angles At Each End Of Driveline; Determining Driveline Length - Blizzard B54 Operator And Parts Manual

Unequal Angles at Driveline Joints
Avoid

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
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.
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
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.
