Deck Leveling Procedure
1. Position the mower on a smooth, level sur-
face, and set the deck height to the most
common cutting position. Refer to
Adjusting
Cutting Height on page 43.
WARNING
The machine must be shut off during this
procedure.
2. Place a block of sufficient height under the left
rear corner of the deck housing to remove
tension from the left rear deck support chain.
Detach the left rear deck support chain by
removing the upper bolt from the height ad-
juster arm. Remove the block and let the deck
hang from the remaining three support chains.
3. Measure the side-to-side level of the deck by
measuring from the ground to the top of the
deck housing at the front corners of the deck
as shown in the
Deck Leveling
illustration.
The side-to-side measurements should not
vary by more than 1/8 in. (3 mm). If neces-
sary, raise or lower the left and/or right front
support chain clevises to level the deck.
4. Measure the front-to-rear level of the deck
using a straight edge as shown in the
Deck
Leveling
illustration. The rear measurement
should be 1/4 in. (6 mm) to 3/8 in. (10 mm)
higher than the front measurement. If neces-
sary, adjust the right side height adjustment
rod by lengthening it to lower the back of the
deck, or shortening it to raise the back of the
deck.
5. With the side-to-side and front-to-rear deck
level correct, reattach the left rear support
chain that was removed in step 2. Adjust the
left side height adjustment rod to equalize the
left rear and right rear support chain tension.
6. Assure that all fasteners are tight and replace
any guards removed during the leveling proce-
dure.
