BLADES WITH ROUND HOLE:
• To check blade balance, drive a nail into
a beam or wall. Leave about one inch of
the straight nail ex posed. 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.
BLADES WITH "STAR" HOLE:
• To check blade balance, you will need
a 5/8" diameter steel bolt, pin, or a cone
balancer. (When using a cone bal anc er,
follow the in struc tions supplied with
bal anc er.)
NOTE: Do not use a nail for balancing
blade. The lobes of the center hole may
appear to be centered, but are not.
• Slide blade on to an unthreaded portion
of the steel bolt or pin and hold the
bolt or pin parallel with the ground. If
blade is bal anced, it should remain in a
horizontal po si tion. If either end of the
blade moves downward, sharpen the
heavy end until the blade is balanced.

DRIVE WHEELS
Check 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 drive wheels.
• If after cleaning, the drive wheels do not
turn freely, contact your nearest autho-
rized service center.
18" (45cm) HI-VAC MODELS ONLY:
1. Remove hubcaps (if equipped) and
locknuts.
2. Remove wheels from wheel ad just er
axles.
3. Remove any trash or grass cut tings
from inside the dust cover, pinion gear
and drive wheel gear teeth.

IMPORTANT: The pinion gears (on both
sides of the mower) are the same, how-
ev er, they must be installed cor rect ly. If

not work.
5. There are arrows embossed on both
sides of the pinion gear. With the ar-

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.
