Maintenance

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.
