two “A” thick blocks (see Block Height and Rake
Table in Leveling the Mower Deck) 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 4)
on all four corners so that the deck is sitting
securely on all four blocks. Make sure that the
deck hangers are all the way down (at the top of
the slot) and the deck lift foot lever is pushed back
against the stop, then tighten the four leveling
adjust locking nuts (Figure 43).

8. Carefully rotate the blades so they are facing front
to rear (Figure 44 and Figure 45).
9. Measure from the tip of the front blade to the
flat surface and the tip of the rear blade to the
flat surface (Figure 44 and Figure 45). If the front
blade tip is not “R” (see Block Height and Rake
Table in Leveling the Mower Deck) lower than
the rear blade tip, adjust the front deck hanger.
