Deck Leveling
The mower deck and support frame are jig welded;
within normal tolerances, very little, if any, shim-
ming should be required to level the deck. Tire
pressure will influence the levelness of the deck.
Check the tire pressure of all pneumatic tires as a
possible cause of the deck not being level.
1. Position mower on a smooth, level surface.
Set the cutting height to the highest position
- 4 in. (102 mm) - for easy access under the
deck to measure blade height. Refer to
Ad-
justing Cutting Height on page 44.
NOTE:
A block of wood cut
4 in. (102 mm)
high is a convenient gauge to measure blade
height above ground during the leveling pro-
cess.
WARNING
The machine must be shut off during this
procedure.
2. Check the side-to-side level.
Rotate each
blade sideways
and measure the distance
from blade tip to ground on each side. If mea-
surements vary more than 1/8 in. (3 mm), add
a washer shim under the deck support pins on
the low side to level the deck.
3.
Check the front-to-rear level.
Rotate the
blades to point forward.
Measure the dis-
tance from blade tip to ground on the front and
rear. The rear of the blade should be 1/8 to
1/4 in. (3 to 6 mm) higher than the front of the
blade; shim the rear (or front) deck support
pins equally to achieve
at least
1/8 in. (3 mm)
difference.
Deck Leveling
NOTE:
For the DS52 deck with three (3) stag-
gered blades, the front-to-rear level should be
set using the middle blade pointing forward, and
either outside blade pointing back.
