be checked and/or adjusted.
Determining if the Deck Leveling Needs to be
Adjusted

engage the parking brake, turn the ignition switch to OFF,
and remove the ignition key.
2. Lock the deck lift pedal in the TRANSPORT position.
Place the cutting height adjustment pin in the 4" position
and lower the deck lift pedal until the deck lift arm
contacts the cutting height adjustment pin.
3. Verify that the tires are inflated to the correct pressure.

broken. A bent or broken blade must be replaced.
