When grinding, care should be taken to maintain blade bal-
ance and the blade should be checked for proper balance
before reinstatlation on mower, Unbalanced or bent blade
will cause excessive vibration when running, and eventual
damage to mower or engine Replace bent, damaged or un-
balanced blades,
To check Blade balance, drive a nail into a beam or wall.
Leave about one inch of the straight nail exposed. Place
Center Hole of clean Blade over the head of the nail (Fig,
22). NOTE: CENTER HOLE OF BLADE ON NAIL IF
BLADE tS PROPERLY BALANCED, BLADE SHOULD
REMAIN IN POSITION SHOWN IN FIG 22. IF EITHER
END OF THE BLADE MOVES DOWNWARD, BLADE IS
NOT BALANCED AND MUST BE REPLACED.
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=

mowing, Do not attempt to sharpen while on mower,
