SECTION 2: OPERATING THE BLADE
SECTION 3: ADJUSTMENTS
CAUTION: Inspect the area to be worked
carefully before operating the snow blade.
Avoid pipes, roots, curbs or other heavy
obstructions.
To Adjust Blade Spring
The blade adjust spring allows the blade to tilt forward to
bypass solid obstructions. The normal adjustment is for
the spring bolt to extend 1" through the top of the blade.
The lift handle, located on the left side of the snow blade,
is used to raise and lower the blade. Pulling the lift handle
all the way back raises the snow blade. Move the lift
handle forward to lower the snow blade to the ground.
The angle of the blade can be adjusted to the right or left
by pulling back on the angle lock bar, shown in figure 15,
and repositioning the head of the blade to the right, left or
center.
To increase the spring tension loosen the knob, screw
the nut farther down onto the bolt and then retighten the
knob.
To decrease the spring tension loosen the knob, screw
the nut farther out toward the end of the bolt and then
retighten the knob. Refer to figure 8 on page 6.

To Adjust Skid Shoes
The skid shoes at the ends of blade may be raised for
close work on smooth surfaces or lowered to raise the
blade to work on rough or uneven areas. Make sure both
shoes are set evenly and that the nuts are retightened
securely.
Figure 15
CAUTION: Know the terrain. Avoid
exceptionally sharp slopes or drop offs which
may be hidden by the snow. Never run the
snowbladeintoheavymaterialathighspeed.
Always begin with the engine speed at the lowest pos-
sible setting, and gradually increase speed as required.
When working in a large area, do not attempt to move the
snow or dirt all in the same direction, causing an exces-
sive buildup, which would become larger with each pass.
CAUTION: Always lower blade to ground
before leaving tractor.
