Adjusting the Side-to-Side
Leveling and the Blade
Slope
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 Checking for Bent Blades ( page 67 ) before
continuing.
Level the mower deck side-to-side rst; then you can
adjust the front-to-rear slope.
Requirements:
• The machine must be on a level surface.
• All tires must be properly inated; refer to Checking
the T ire Pressure ( page 57 ) .
1. Park the machine on a level surface, disengage
the blade-control switch (PT O), and engage the
parking brake.
2. Shut of f the engine, remove the key , and wait
for all moving parts to stop before leaving the
operating position.
3. Check the tire pressure in the drive tires; refer to
Checking the T ire Pressure ( page 57 ) .
4. Position the mower deck in the transport-lock
position or the highest height-of-cut setting.
5. Carefully rotate the blades from side to side.
