GRASS
CATCHER
• The grass catcher
may be hosed with
water, but must be dry when used.

often for
damage
or deterioration.

turer approved
replacement

DRIVE WHEELS
Check rear drive wheels each time you
mow to be sure they move freely. The
wheels not turning freely
means trash,
grass cuttings, etc., may be inside the
drive wheel and dust cover area and must
be cleaned
out to free drive wheels.
If necessary
to clean the drive wheels,
check both rear wheels.
• Remove
hubcaps
and Iocknuts.
• Remove
wheels
from wheel
adjuster
axles.

any trash or grass cuttings
from inside the dust cover, pinion and/
or drive wheel
gear teeth.
• If you remove the drive pinions, wipe
clean with dry cloth.
Reassemble
dry.
Do not lubricate. Do not use oil or
grease.
• The pinion
gear, on both sides of the
mower,
are the same,
however,
they
must be installed
correctly.
If installed
incorrectly,
the drive system
will not
work.
• There
are arrows
embossed
on both
sides of the pinion gear.
With the arro.
at the top of the pinion,
the arrow must
point towards
front of mower.
If the
arrow points to the rear, turn the pinion
around
and assemble
to mower.

NOTE:
Although mu_viscosity
oils (5W30,
10W30 etc.) improve starting in cokl weather,
these multi-viscnsify
oils will result in
increased oil consumption when used above
32_F. Check your engine oil level more
frequently to avoid possible engine damage
from running low on oil.
Change the oil after every 25 hours of
operation or at least once a year if the lawn
mower is not used for 25 hours in one year.
