TRANSMISSION LOCKOUT
IMPORTANT: DO NOT TOW this mower with the
transmission lockout engaged. Towing can produce
excessive internal pressure and damage the
transmission.
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
transmissions.

4. After moving the mower, release the locking
cam, placing the lever DOWN in the normal
OPERATING position. Make sure the trans-
mission lockout plunger on the side of the trans-
mission case (activated by the lockout lever) is
completely released, otherwise the transmis-
sion operation will be erratic.

RECOMMENDATIONS FOR MOWING
IMPORTANT: Operate the engine at full speed
when mowing, to allow the engine to produce full
horsepower and to increase efficiency of the engine
cooling system.
Keep the mower deck and discharge chute clean.
Mow with sharp blades. A dull blade tears the
grass (resulting in poor lawn appearance) and uses
extra power (slowing the mowing speed).
It is preferable to cut grass when it is dry and not
too tall. Mow frequently and do not cut grass too
short. (For best appearance, cut off 1/3 or less of
existing grass height.)
When mowing, operate the engine at or near full
throttle for the best cutting action and performance
of the grass handling system (GHS). Mowing with a
lower engine RPM causes the mowing blade to not
cut clean and tear the grass. The engine is
designed to be operated at full speed.
When mowing in adverse conditions (tall and/or
wet grass), mow the grass twice. Raise the mower to
the highest setting - 4 in. (102 mm) - for the first pass
and then make a second pass cutting to the desired
height.
Use a slow setting on the FSC for trimming
operations.
