DRIVELINE ATTACHMENT

Preparation of the Driveline
IMPORTANT: To obtain the proper universal joint an-
gles, it is recommended to adjust the 3-Point hitch at
the furthest point from the tractor recommended by the
manufacturer. The universal joint angle is directly re-
lated with the life of driveline. To reduce the angle, it is
necessary to increase the distance between the snow
blower and the tractor.
IMPORTANT: Do not change the snow blower angle on
the tractor hitch to obtain a better scraping effect. Avoid
this practice as it can damage the driveline since the
joint angle at each end is unequal. This results in a fan
speed variation as well as an increased load on drive-
line bearings. It is always recommended to keep tractor
PTO shaft and snow blower input shaft parallel.

IMPORTANT: Before using the snow blower, make
sure the driveline is the proper length. There must be
sufficient overlap of the inner and outer drive tubes but
there must not be any interference.
1. To determine the "L" length for your tractor model
first find the "X" distance by measuring between the
end of the tractor's PTO shaft and the end of the
snow blower's input shaft when the snow blower is
in transport position as shown, when raised to max-
imum height.
