operating equipment.
3. Make sure the snowblower is clear of snow
before engaging the driveline.

necessary, add SAE 80W90 gear oil, AGMA
5EP oil or equivalent.
6. Check the two shear bolts, one on the drive
shaft and one on the PTO shaft for proper

OPERATING CONTROLS
Raising and Lowering Snowblower
Move the three point lever down or forward to
lower, and up or rearward to raise.
Work and Travel Speed
Working ground speed will depend on the depth
and density of the snow to be cleared. Normally,
ground speed will range from 4 to 7 MPH for
light, dry snowfalls 3 to 6 inches, and 1 to 3 MPH
for heavy, wet or drifted snow. To transport,
disengage the drive shaft and raise the
snowblower to full transport height.
PTO Operation
The driveline is activated by pulling up the
driveline lever on left side of seat. Push down to
disengage.
ADJUSTMENTS
WARNING
To avoid personal injury, be sure the tractor
engine is off, the drive shaft disengaged, and
all movement has stopped before making any
adjustments.
Skid Shoe Adjustment
Adjust the snowblower so that the skid shoes run
level. Adjust the skid shoes according to the
surface conditions so that stones are not thrown
with the snow, and adjust upwards for smooth
surfaces. Adjust both skid shoes to the same
height to keep the cutting edge level.
To adjust skid shoes, remove the pins and
reinsert in the hole appropriate to the surface
conditions:
Clearance between cutting edge and surface:
·Level paved surface: Adjust to 1/16" to 1/8"
.Uneven or gravel surface: Adjust to 1/2" and more
according to size of gravel.
