4. Place three short 51 mm (2 in.) blocks of wood under the edges (A) of
the mower deck.

• If the rear of the mower deck is not touching the rear blocks, or is
sitting heavily on the blocks, adjust the rear lift links by turning the
leveling nut (B) on each lift link. The blocks should be able to easily slide
in and out beneath the mower deck when the mower deck is correctly
adjusted.

• If the front of the mower deck is not lightly touching the front block,
adjust the front draft arm by turning the nut (C).
7. Raise the cutting height to the next highest position and remove the
three wooden blocks.
8. Turn the nut (C) on the front draft arm counterclockwise 1-2 full turns so
that the front of the deck is 3-6 mm (1/8-1/4 in.) lower than the rear. This
adjustment prevents “double cutting,” which wastes horsepower and
causes brown grass tips.

2. Park machine safely. (See Parking Safely in the SAFETY section.)
3. Inflate tires to the correct pressure.
4. Move mower lift handle to preferred cutting height.
