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

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 46)
.
Leveling from Side to Side
1.
Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
