Troubleshooting, Adjustment & Service
CUTTING HEIGHT ADJUSTMENT
The cutting height adjustment pin (A, Figure 29) controls
the mower cutting height. The cutting height is
adjustable between 1-3/4(4.4cm) and 5(12.7cm) in
1/4(.64cm) increments.
Depress the deck lift foot pedal (B, Figure 29), placing
the majority of the force on the top edge of the pedal
until it locks into the TRANSPORTposition. Place the
cutting height adjustment pin in the desired cutting
height. Depress the deck lift foot pedal, placing the
majority of the force on the bottom edge of the pedal to
release the pedal from the TRANSPORTposition.
DECK LEVELING ADJUSTMENT
1. Park the machine on a flat, level floor and engage
the parking brake. Rear tires must be inflated to 15
psi; front tires to 20 psi.
2. With the deck height adjustment pin in the 4" posi-
tion, adjust the 5/8hex nuts on either side of the
front spring rod pivot (see Figure 30) until the rear
lower edge of the cutter deck directly behind the
chain is 3-5/8" from the floor. The front lower edge of
the cutter deck directly in front of the eyebolt should
be 3-1/2" from the floor (4-1/2for ACP deck). If not,
adjust the front deck hanger eyebolt to correct the
cutting height. Perform this step to both rods.
3. With the deck height adjustments complete and cut-
ting height still set at 4", adjust the deck lift spring to
a compressed length of 14-1/4" (measure spring
only). Adjust the length of the deck lift spring by
tightening or loosening the (2) 5/8hex nuts that are
closest to the spacer at the front end of the spring
(see Figure 30). After adjustment is made, tighten
these two nuts together. Perform this step to both
springs.
WARNING
Before checking mower, shut off PTO and engine.
Allow all moving parts to stop. Remove ignition
key, then disconnect the spark plug wire and
fasten it away from the spark plug.
