4. Measure carrier frame height at location A
(Figure 63).
5. Measure carrier frame height at location B
(Figure 63).
6. If the carrier frame height is not the same move
spacers from top or bottom of caster wheel, to
make it level. The tire pressure may also be adjusted

1. Adjust the tire pressure in the rear tires to
specifications; refer to Drive System Maintenance

inch mower decks use Figure 65.
3. The mower blade should be a 1/4 inch (6 mm) lower
in front at A than in the rear at B. Rotate blades and
repeat for other blades. If it is not correct, proceed
to Changing the Deck Front-to-Rear Pitch.
