5. Turn the deck support pins to lengthen or shorten
the pins to reach the desired result.
6. Tighten the jam nut, replace the hair pin, and
remove the blocks. Check that the desired deck
pitch is achieved.
CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, it is difficult
to suggest a cutter deck setting that will work for every
lawn. There are two adjustments that can be made on
these decks, pitch and height.
PITCH is the angle of the blades in relation to the ground
(comparing front to rear). The pitch of the cutter blades
should be equal between the front and rear for proper
cutting performance. To check for proper deck pitch, be
sure that the mower is on a flat, level surface and the
tires are properly inflated.
Figure 2. Cutting Height Adjustment
The cutter deck pitch adjustment has been set at the
factory and normally will not need to be changed.
However, if the pitch needs to be adjusted due to service
work performed on the deck, follow the procedure below
(see Figure 3, Page 11).
1. Shut off the engine and remove the key.
2. Support the cutter deck with four blocks (you
will be removing the hair pins to make this
adjustment).
3. Remove the front hair pins from the front deck
support pins.
4. Loosen the jam nuts on the deck support pins.

HEIGHT is the nominal distance the blade is off of the
ground. This measurement is made with the blades
pointed side to side and distance is measured between
cutting tip and ground.
Changes to the cutting height can be achieved by reposi-
tioning the cutter deck. There are eight available posi-
tions from 1" to 4-1/2" (See Figure 2).
Do not adjust the cutting height with the mower
blades rotating. Shut off the engine and remove
the ignition key. Bodily injury could occur from
the rotating blades.
WARNING:
4. Repeat the above process on the opposite side of the
cutter deck.
1. Shut off the engine and remove the ignition key.
2. While holding up on the deck support handle, remove
the two hairpins from the adjusting pins on one side
of the cutter deck (See Figure 2).
3. Lift or lower the deck to the desired cutting height
and reinstall the hairpins. A deck height decal is
located on the deck mounting frame as an aid in
adjusting the deck to the desired height.
