Operating Instructions

Cutting height is adjusted by positioning the four re-
tainer hitch pins in a series of seven 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 in. (25 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.

sion operation will be erratic.
