Deck Leveling - Walker D21d Operator's Manual

Assembly Instructions

Deck Leveling

The mower deck and support frame are jig welded;
within normal tolerances, very little, if any, shimming
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 ADJUSTING
CUTTING HEIGHT in Operating Instructions.
NOTE: A block of wood cut 4 in. (102 mm) high
is a convenient gauge to measure blade height
above ground during the leveling process.

NOTE: For DS52 and DS62 decks with three (3)
staggered blades, the front-to-rear level should be
set using the middle blade pointing forward, and
either outside blade pointing back.
The machine must be shut off during this
procedure.
2. Check the side-to-side level.
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 distance 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.
