Commercial Snowblower

ASSEMBLY INSTRUCTIONS – cont’d.

b)Using tape or a bright colored marking pen, mark on the outer shields 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.

c)With the engine on the tractor shut off, attach the PTO shaft. The tractor end has a standard 6-spline end with a spring loaded locking collar. The snowblower end has a clamp-style yoke with a 3/8” key way. Slide the yoke onto the gearbox shaft with the 3/8” key supplied. Lock the yoke in place with the ½” x 3” 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.

Caution: 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.

d)Check that the PTO shaft does not bottom or separate with the blower in the extreme high and low positions. A longer optional PTO shaft is available if the standard shaft is too short. Check for free movement of all parts in various raised positions; particularly the PTO shaft.

e)NOTE: Excessive U-joint wear and shear pin failure may result if the tractor PTO angle exceeds 20º. The drawing below gives an approximate way to check this angle. With the PTO half extended, the tractor output should not be over 32 inches high. Use 34 inches if the PTO is nearly compressed.
