steering levers and simultaneously (2)
Move the FSC to the NEUTRAL-PARK

justing cutting height. Disengage the blade
clutch (PTO), engage the parking brake,
stop the engine, and remove the ignition

getting o󰀨 the seat.
Cutting height is adjusted by positioning the four (4)
re tainer hitch pins in a series of six vertical holes on
the deck support pins. Lift handles have been pro-
vided on each end of the deck to assist in raising the
deck while positioning the hitch pins. Cutting heights
range from 1.5 in. (38 mm) [top holes] to 4 in. (102
mm) [bottom holes] in 1/2 in. (13 mm) incre ments.

TRANSMISSION LOCKOUT
IMPORTANT: DO NOT TOW this mower with the
transmission lockout engaged. Towing can produce
excessive internal pressure and damage the trans-
mission.
To move the mower with the engine NOT running
(dead battery, maintenance, etc.), the hydrostatic
transmissions are unlocked (released).
1. Raise the body.
2. Lift the transmission lockout lever on both the
RH and LH transmissions and secure into place
with the locking cam.
3. The mower will “freewheel” with the levers in the
LOCKOUT position. The levers must be in the
highest position to completely unlock the trans-
missions.
