Maintaining
Your Lawn
Mower
WARNING
When removing the
cutting blade or when
sliding the belt around it,
protect your hands with
a pair of heavy gloves or
use a heavy rag to hold
the blade.
An unbalanced blade
will cause excessive
vibration when rotating
at high speeds. It may
cause damage to mower
and could break causing
personal injury.
Figure 5-2: Remove bolt, bell blade support, and blade.
Figure 5-3: Remove cover, unhook spring, and pull belt off of
pulley.
Figure 5-4: Remove belt from around the blade.
4. Place the blade on the adapter such that the side
of the blade marked “Bottom” (or with part number)
faces the ground when the mower is in the operating
position. Make sure that the blade is aligned and
seated on the blade adapter flanges.
5. Place bell blade support on the blade. Align notches
on the support with small holes on blade. Replace hex
bolt and tighten hex bolt to torque: 450 in. lbs. min.,
600 in. lbs. max.
To ensure safe operation of your mower, periodically
check the blade bolt for correct torque.
Changing the Belt
1. Remove the front drive cover by sliding off the
two plastic rivets on each side of the cover with a
screwdriver, Figure 5-3.
2. Unhook the extension spring from the height adjust-
ment plate, Figure 5-3. This will loosen the tension on
the belt.

transmission pulley, Figure 5-3.
4. Lift mower to access belt from underside of mower.
Slide belt off of engine pulley and around the blade,

sure belt is firmly seated on engine pulley while pulling
from the other side and sliding it around the transmis
-
sion pulley.
6. Put the mower down with all four wheels firmly placed
on one level. Reattach the extension spring and
reassemble the front drive cover.
Off-Season Storage
The following steps should be taken to prepare your lawn
mower for storage.
• Clean and lubricate mower thoroughly as described
in the lubrication instructions. Do not use a pressure
washer or garden hose to clean your unit.
• Refer to engine manual for correct engine storage
instructions.
• Coat mower’s cutting blade with chassis grease to
prevent rusting.
• Store mower in a dry, clean area. Do not store next to
corrosive materials, such as fertilizer.
When storing any type of power equipment in a poorly
ventilated or metal storage shed, care should be taken to
rust-proof the equipment. Using a light oil or silicone, coat
the equipment, especially cables and all moving parts of
your lawn mower before storage.
