This will result in a more even distribution

be discharged away from shrubs, fences, driveways, etc.
After two or three rounds, mow in the opposite direction

CARE
For best results mower blades must be kept sharp, The blades
can be sharpened with a few strokes of a file or on a grinding
wheel We suggest they be sharpened after every 15 hours of
mowing° Do not attempt to sharpen while on mower.
1. When grinding, care should be taken to maintain blade balance and the blade should be checked for proper balance
before reinstallation on mower_ Unbalanced or bent blade
will cause excessive vibration when running and eventual
damage to mower or engine° Replace bent or damaged
blades_
2. To ensure satisfactory operation, it is recommended that
before the start of each mowing season, the oldblades be
discarded and replaced with new blades. Mower blades can
be purchased at any Sears Service Center/Departments and
