5.Check and adjust the side-to-side blade level if you have not checked the setting; refer to Deck Leveling.

6.Set the height-of-cut lever to the 3 inch (76 mm) position. Place two “B” thick blocks (see Block Height and Rake Table in Deck Leveling) under the rear edge of the cutting deck skirt; one on 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 26) 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.
