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 (figure 25) 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.
2. Choose in the table below the "Y" factor
according to the tractor category and deduct
that number from
"X" (figure 25) to determine
"L" (figure 26) which is the center-to-center
length between the universal joints.
L = X – Y
