RESPONSIBILITIES
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

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