Operation - 1080 Snowblower
Operation Instructions
1. Do not operate the snowblower in the fully raised position. The 3-point hitch on some tractors
raises 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 snowblower forward or backward. Adjust
the top link of the tractor 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. Adjust the lower link sway chains or blocks on the tractor to restrict side movement of the
snowblower when operating.
4. The snowblowers may be purchased with either of two available spouts. Both spouts have
hydraulically controlled spout deflectors. The standard spout should be suitable for all general
snow blowing applications. The truckloader spout was designed to blow directly onto the back
of a truck. The maximum height of the truck side you blow over should be approximately 10 ft.
5. Run the snowblower at low RPM to check operation before blowing snow.
6. The snowblower has shear bolts to protect the tractor and snowblower in case a large object
enters the snowblower. The PTO shaft uses two - 3/8" x 1" (Grade 2) hex bolts as shear bolts.
The drive shaft uses one - 5/16" x 1-1/4" (Grade 5) hex bolt as a shear bolt. Shear bolts should
be fastened with a lock nut. These bolts must be kept tight to prevent wear of the bolt and bolt
holes.
7. Never run PTO shaft over 1000 rpm.
8. Chain Tension: Slack on the lower side of the chain should be 3/8" to 1/2".
9. Lubrication:
- The spout clamps and rings should be periodically lubricated with gun grease. This is
particularly important on the truckloader spout which turns harder than the standard spout
due to length and weight.
- PTO shaft universal joints and square shaft slide should be greased daily.
- Regularly oiling the chain will significantly increase the life of the chain.
- The grease fitting on the hydraulic spout swivel arm should be kept lubricated.
- Use only 80-90 gear oil on multi grade with 80 minimum in the gearbox up to the level
plug height.
