Wheel weights and tire chains must be used with
your snow blade for traction. These accessories are
available at your nearest Sears retail store.
Using the Snow blade
• Prepare the lawn tractor engine for cold weather
using instructions furnished with the lawn tractor.
• Alwaysbeginwiththetransmissioninrst(low)gear
and gradually increase speed as required.
• Do not repeatedly push snow in the same direction.
This causes excessive build up with each successive
pass.
• To reduce icing on the blade, allow the lawn tractor
and blade to adjust to outdoor temperature before
operating.
• For improved snow removal performance, coat the
blade with automotive type paste wax.
CAUTION: Carefully inspect the area
to be worked before operating the snow
blade. Avoid pipes, roots, curbs or other
heavy obstructions.
CAUTION: Know the terrain. Avoid
exceptionally steep slopes or drop-offs
which may be hidden by the snow.
Never run the snow blade into heavy
material at high speed.
CAUTION: Always lower the blade to
the ground before leaving the tractor.

CHECK FOR LOOSE FASTENERS
• During the operating season, check all bolts, nuts and
hairpin cotters to be sure they are secure.
CHECK FOR WORN OR DAMAGED PARTS
• During the operating season, check for worn and
damaged parts. Replace or repair any that have
excessive damage or wear.
CLEAN BLADE
• During the operating season, clean the blade off after
each use. Touch up any bare metal with paint or
apply a light coat of grease or rust preventive.
LUBRICATE BLADE
• Lubricate all pivot points to help maintain proper
operation of blade. Apply a light coating of oil to the
straight upper portion of the lift handle rod.

To Adjust Blade Spring
• The tension of the blade adjust spring may be altered
to permit the blade to tilt forward to bypass solid
obstructions. To change the spring tension, adjust the
nuts at upper end of the spring bolt. Standing in front
of blade, turn the nuts counterclockwise to relieve
tension and clockwise to increase tension. Refer to
gure21onpage11.
To Adjust Blade Shoes
• The blade 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
tightened securely.
SERVICE AND ADJUSTMENTS
FIGURE 30
To Adjust the Blade Pivot Lock Mechanism
• If the blade will not unlock and pivot, the angle lock
bars are not disengaging from the slots in the pivot
plate. To correct, adjust the 5/16" hex jam nuts to
draw the end of the control cable back towards the
cable mount bracket. The less the threaded end of
the cable extends through the bracket, the more the
angle lock bars can retract to disengage from the
slots in the pivot plate.
