Equal Angles at Driveline Joints

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.
