(Continued From Previous Page)
2. Front to Rear Deck Pitch (42” Decks)
With the YARD CRUISER on a smooth, level
surface, rotate blades 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 1/4” higher than the front. If the rear blade
tip is lower or is more than 1/4” higher than the
front, proceed with adjustment.
a. Remove rear hanger chains.
b. Turn each hanger pivot the same number of
rotations on the eye-bolt to raise or lower the
rear of the deck. See Figure 4.8.
c. Reinstall rear hanger chains and measure
blade tips again.
d. Repeat steps “a” through “c” until proper
levelness is obtained.
