amount of material is removed from both cutting
edges.

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.
Check the mower deck for bent blades prior to
leveling, and remove and replace any bent blades;
refer to the Servicing the Cutting Blades (page 42)
before continuing.
Level the mower deck side-to-side first; then you can
adjust the front-to-rear slope.
Requirements:
•
The machine must be on a level surface.
•
All tires must be properly inflated; refer to
the Tire Pressure (page
Checking the Side-to-Side Level

operating position.
3. Set the height of cut to 76 mm (3 inches).
