Operating Instructions

#960 Snowblower

1.Do not operate the blower in the fully raised position. The three-point hitch on some tractors rises high enough to cause the PTO shaft to bind. This can cause damage to the PTO shaft and/or to the hitch and pins.

2.Depth of cut can be partially controlled by tilting the blower forward or backward. Adjust the tractor quick hitch so the snowblower is just slightly tilted back when resting on the ground.

CAUTION: Excessive backward tilt may cause the "U" joints to flutter resulting in PTO shear bolt failure.

3.Run the blower at low rpm to check operation before blowing snow.

4.The snowblower has two shear bolts to protect the tractor and blower in case a large object enters the blower. PTO shear bolt - two 5/16" x 1" (Grade 8); Auger shear bolt – 5/16” x 1 ¼” (Grade 5). Shear bolts should be fastened with a lock nut or two jam nuts. These bolts must be kept tight to prevent wear of the bolt and bolt holes.

5.Never run PTO shaft at over 600 rpm.

6.Chain Tension: Slack on the lower side of the chain should be 3/8” to ½”.

7.Lubrication:

a)The spout clamps and rings should be periodically lubricated with gun grease.

b)PTO shaft universal joints and square shaft slide should be greased daily.

c)Regularly oiling the chain will significantly increase the life of the chain.

d)The grease fitting on the hydraulic spout swivel arm should be kept lubricated.

e)Gearbox - Use any 80-90 gear oil or multigrade with 80 minimum.

8.Periodically check all bolts for tightness. The bolt holding on the fan and the bearing bolts are of particular importance.
