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.
