IMPORTANT: Blade bolt is grade 8 heat
treated.
TO SHARPEN BLADE
NOTE: We do not recommend sharpen-
ing blade - but if you do, be sure the
blade is balanced.
Care should be taken to keep the blade
balanced. An unbalanced blade wilt
cause eventual damage to lawn mower
or engine.
• The blade can be sharpened with a file
or on a grinding wheel. Do not attempt
to sharpen while on the mower.
• 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 blade over the head of
the nail. If blade is balanced, it should
remain in a horizontal position. If either
end of the blade moves downward,
sharpen the heavy end until the blade
is balanced.

GRASSCATCHER
• The grass catcher may be hosed with
water, but must be dry when used.
• Check your grass catcher often for
damage or deterioration. Through
normal use it will wear. If catcher
needs replacing, replace only with a
manufacturer approved replacement
catcher. Give the lawn mower model
number when ordering.
DRIVE WHEELS
Check front drive wheels each time
before you mow to be sure they move
freely.
The wheels not turning freely means
trash, grass cuttings, etc. are in the drive
wheel area and must be cleaned to free
drive wheels.
If necessary to clean the drive wheels,
check both front wheels.
• Remove hubcaps, hairpin cotters and
washers.
• Remove wheels from wheel adjusters.
• Remove any trash or grass cuttings
from inside the dust cover, pinion and/
or drive wheel gear teeth.
• Put wheels back in place.
• If after cleaning, the drive wheels do
not turn freely, contact your nearest
authorized service center.
GEAR CASE
• To keep your drive system working
properly, the gear case and area
around the drive should be kept clean
and free of trash build-up. Clean under
the drive cover twice a season.
• The gear case is filled with lubricant to
the proper level at the factory. The only
time the lubricant needs attention is if
service has been performed on the
gear case.
• If lubricant is required, use only Texaco
Starplex Premium 1 Grease, Part No.
750369. Do not substitute.
