BLADESHARPENINGAND BALANCING(All Models)
IMPORTANT : Professional
sharpening services or your
local dealer are equipped to
sharpen mower blades safely.
We recommend that the blade
be professionally sharpened.
Replace a cracked or severely
worn blade with a new one.
A. Remove blade from mower as
described in "Blade Maintenance."
Check for blade wear or damage.
B. Clamp the blade in a vise. Use
a metal file or grinder to sharpen
the blade while maintaining origi-
nal cutting angles.
C. To retain blade balance, re-
move the same amount of material
from both ends of the blade.
D. To make sure that the blade is
properly balanced, place blade on
a rounded pencil or pen (or other
pivot) under center hole. Hold
blade parallel to ground. See
Figure 5-18. If blade is unbal-
anced, the heavier side will lean
downward.

CLEANINGUNDERDECKAND UNDERMOWERCOVER(All Models)
Correct procedures should be
followed when clearing grass
build-up to ensure proper func-
tioning of the wheel drive system
on self-propelled models.
WARNING
• Before performing any
maintenance procedures,
stop the engine, wait for all
moving parts to stop, and
allow the engine to cool.
Disconnect the spark plug
wire and move it away from
the spark plug. Remove ig-
nition key on electric start
models.
• When working near the
blade, wear heavy leather
gloves to protect yourself
from the sharp edges on the
blade.
NOTE:
• Loss or slipping of wheel drive
can occur after washing underside
or under cover of mower. Let
parts dry thoroughly after using
water spray to clear grass build-
up.
Cleaning Underside of Mower
Deck:
A. Check the mower regularly for
grass build-up.
B. Cleaning under mower deck
should be done after (rather than
before) operating the mower.
C. Scrape off excess grass. If
using a hose to remove grass
build-up, let the mower dry thor-
oughly before operation.
IMPORTANT: Loss or slipping
of the mower's wheel drive can
occur if the rubber friction disk
is wet.
° If tipping mower during a main-
tenance procedure, tip mower
rearward rather than forward or to
either side.
Cleaning Under Mower Cover:
A. Check underside of mower
cover for grass build-up at the be-
ginning and in the middle of each
mowing season.
B. Remove the front cover of the
mower by removing the two
phillips head screws which secure
the cover. Pull the cover up and
then forward.
C. Temporarily install one of the
cover screws into the spring
retaining bracket (H, Figure 5-6).
D. Scrape out any grass build-up.
(If water is used to clean this area
of the mower, the mower should
be allowed to dry thoroughly be-
fore operation.)
IMPORTANT: Loss or slipping
of the mower's wheel drive can
occur if the rubber friction disk
is wet.
E. Check that the three (3) drain
holes in the mower deck are un-
clogged.
F. Remove the Phillips screw
from the spring retaining bracket
and reinstall the front deck cover
using the two screws.
