Leveling the Mower Deck

Check to ensure the mower deck is level any time you
install the mower or when you see an uneven cut on
your lawn.
The mower deck must be checked for bent blades
prior to leveling; any bent blades must be removed
and replaced. Refer to the Checking for Bent Blades
procedure before continuing.
The mower deck must be leveled side-to-side first then
the front to rear slope can be adjusted.
Requirements:
• The machine must be on a level surface.
• All four tire must be properly inflated. Refer to
Checking the Tire Pressure in the Drive System
Maintenance section.
Side-to-Side Leveling

the blade control switch.
2. Move the motion control levers outward to the
park position, stop the engine, remove the key, and
wait for all moving parts to stop before leaving the
operating position.
3. Set the height-of-cut lever to middle position.

are not within 3/16 inch (5 mm), an adjustment is
required; continue with this procedure.

blocks under the edges of the deck.
