SECTION 2: OPERATING THE BLADE

CAUTION: Inspect the area to be worked

carefully before operating the snow blade.
Avoid pipes, roots, curbs or other heavy
obstructions.

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.

SECTION 3: ADJUSTMENTS

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.

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
snow blade into heavy material at high speed.

Always begin with the engine speed at the lowest pos­sible 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 exces­sive buildup, which would become larger with each pass.

CAUTION: Always lower blade to ground

before leaving tractor.
