4.2 MOWER DECK & COMPONENT ADJUSTMENTS
4.2.5. MOWER DECK ADJUSTMENT
(Front to Rear Levelness)
Before making deck leveling adjustments, check
the tire pressure. Front tires 12 psi, rear tires 12 psi.
If tires are properly inflated and mowing is still uneven,
adjust side-to-side deck levelness as follows: With the
Rear Engine Rider on a smooth, level surface,
rotate blade until blade tips are at front and rear of
deck. Measure the distance from blade tips to floor.
The distance should be the same, or the rear 1/8" to
1/4" lower than the front. If the rear blade tip is
higher or is more than 1/4" lower than the front,
proceed with adjustment.
1. Remove rear hanger chains.
2. Turn each hanger pivot the same number of
rotations on the eyebolt to raise or lower the rear of
the deck. See Figure 4.5.
3. Reinstall rear hanger chains and measure blade
tips again.
4. Repeat steps "1" through "3" until proper
levelness is obtained.
