BLADE СДВЕ
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 bal­
ance and the blade should be checked for proper balance
before reinstadation on naower. 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 old,blades be
discarded and replaced with new blades. Mower blades can
be purchased at any Sears Service Center/Departments and
most Sears Retail Stores,
