Leveling the Mower Deck

Check to ensure that 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 Checking for Bent Blades (page 33) 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 4 tires must be properly inflated; refer to Checking
the Tire Pressure (page 31).
Side-to-Side Leveling
1. Park the machine on a level surface and disengage 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.
4. Carefully rotate the blade(s) so that they are all side
to side (Figure 49).
