ASSEMBLY INSTRUCTIONS - Cont'd.
4. Mounting Blower on Tractor:
a) Mount the blower on a tractor with a category 2 or 3 standard hitch or a
category 3 quick hitch. The hitch as two holes both at the top of the hitch
and at each lift arm. When using a quick hitch, the pins must be in the
inside
set of holes. Use the outside set of holes with a standard three-
point hitch. The lift arm pins also have a narrow spacing for category 2
and a wide spacing for category 3.
b) Using tape or a bright colored marking pen, mark on the outer shields of
the PTO the position where the shaft is completely pushed together and
the position where you have a 4" overlap. Watch these marks when
moving the blower through all possible operating angles to see that the
PTO shaft stays within this range. Slide the hitch in if necessary to keep
the PTO shaft in this operating range. Do not forget to change the
position of the cylinder arm (#17) by the same distance that you move the
hitch.
c) With the engine on the tractor shut off, attach the PTO shaft. The
tractor end has a 1 3/8" 21 spline end with a spring loaded locking collar.
The snowblower end has a clamp style yoke with a 3/8” keyway. Slide the
yoke onto the 1 ¾” jackshaft with the 3/8" key supplied. Lock the yoke in
place with the 5/8" x 3 ¼” bolt and lock nut fitted through the groove in the
gearbox shaft. After tightening the bolt, insert and tighten the 3/8" socket
set screw supplied.
d) Always check to see that both ends of the PTO shaft are securely
attached every time the snowblower is used. This should always be done
with the tractor engine off.
