OPERATION
NOTE:

Wheel weights and tire chains must be used with
your snow blade for traction, These accessories
are available at your nearest Sears retail store.
If the model of your tractor begins with #536
(model number found in your owners manual or on
the model plate decal), then you will need to use
the 6" bolts included in your wheel weight kit and
discard the longer 8" bolts. Use as instructed to
mount wheel weights to the rear wheels of your
tractor,

CAUTION:

KNOW

THE TERRAIN.

SLOPES OR DROP OFFS WHICH MAY
AVOID
EXCEPTIONALLY
STEEP
BE
HIDDEN
BY THE SNOW.
NEVER RUN THE SNOW BLADE INTO
HEAVY MATERIAL AT HIGH SPEED.

CAUTION: INSPECTTHEAREATO
BE
WORKED
CAREFULLY
BEFORE
OPERATING
THE SNOW BLADE.
AVOID PIPES, ROOTS, CURBS OR
OTHER HEAVY OBSTRUCTIONS.

CAUTION: ALWAYS LOWER BLADE
TO GROUND
BEFORE LEAVING
TRACTOR.

Using the Snowblade
•

Prepare lawn tractor engine for cold weather using
instructions furnished with the lawn tractor.

•

Always begin with transmission in first (low) gear and
gradually increase speed as required.

•

DO NOT repeatedly push snow in the same direction
causing excessive build up with each successive pass.

•

To reduce icing on blade, allow lawn tractor and blade to
adjust to outdoor temperature before operating,

NOTE:

When working under the hood of a SERIES 536
tractor while snow blade is attached, the hood may
not stay up on its own; therefore, you may need to
lay something (such as a piece of wood) over the
engine housing to keep the hood propped up.

CUSTOMER RESPONSIBILITIES
Lubrication
•

Points

Maintenance

Lubricate the points shown in figure 32 for easier operation. Use the grease packet furnished with the snow
blade for lubrication of the lift handle rod and the lift
handle tube assemblies.

During the operating season, check all bolts, nuts and
hairpin cottersto be sure they are secure. For improved
snow removal performance, coat the blade with
automotive type paste wax.

SERVICE.AND ADJUSTMENTS
To Adjust Blade Spring

To Adjust the Biade Pivot Lock Mechanism

®

•

The tension of the blade adjust spring is adjustable to
permit blade to tilt forward to by-pass solid obstrdctions.
To change spring tension (standing in front of blade
assembly), adjust the nuts at upper end of the spring
bolt, turning counter cJookwlse to relieve tension and
clook'wlseto Increase tension, See flgure24on page 13,

the end of the cable extends through the ear, the more
the angle lock bars can retract to disengage from the
slots In the pivot plate, See figure 34,

To Adjust Blade Shoes
•

If the blade will not unlock and pivot, the angle lock
bars are not disengaging from slots in pivot plate. To
correct this condition, adjust the 5/16" hex jam nuts to
draw the end of the control cable back towards the
welded cable mount ear on the handle tube, The less

Blade shoes on ends of blade may be raised for close
work on smooth surfaces or lowered to raise the blade
towork on rough or uneven areas, Make sure both shoes
are set evenly and nuts are tightened securely, See
figure 33,
