each side of the cutting deck. Place two “A” thick
blocks (see Block Height and Rake Table in Deck
Leveling) under each side of the front edge of the
deck, but not under the anti-scalp roller brackets.
7. Loosen the leveling adjust locking nuts (item 1
Figure 27) on all four corners so that the deck is
sitting securely on all four blocks. Make sure that
the slack is removed from the deck hangers and
the deck lift foot lever is pushed back against the
stop, then tighten the four leveling adjust locking
nuts.
8. Carefully rotate the blades so they are facing front
to rear (Figure 28).
9. Measure from the tip of the front blade to the at
surface and the tip of the rear blade to the at
surface (Figure 28). If the front blade tip is not
“R” (see Block Height and Rake Table in Deck
Leveling) lower than the rear blade tip, adjust the
front deck hanger.
