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.
