engine does not kill, there is a malfunction in the
interlock system that should be corrected before
beginning operation.
Note: The safety interlock switches can also be
checked using the diagnostic LED's on the SCM.
Pushing or Towing the
Machine
In an emergency, the machine can be moved forward by
actuating the bypass valve in the variable displacement
hydraulic pump and pushing or towing the machine.
Do not push or tow the machine for more than 1/4
mile (0.4 km).
Important: Do not push or tow the machine
faster than 2-3 MPH (3-4.8 km/h) because internal
transmission damage may occur. The bypass valve
must be open whenever the machine is pushed or
towed.
Important: If the machine must to be pushed or
towed in reverse, the check valve in the four-wheel
drive manifold must also be bypassed. To bypass
the check valve, connect a hose assembly (Hose
Part No. 95-8843, Coupler Fitting No. 95-0985
[Qty. 2], and Hydraulic Fitting No. 340-77 [Qty. 2])
to the reverse traction pressure test port and the
reverse four-wheel drive pressure port.
1. Open hood and remove the center shroud
2. Rotate the bypass valve 90° (1/4 turn) in either
direction to open and allow oil to bypass internally
(Figure 18). Because fluid is bypassed, the machine
can be slowly moved without damaging the
transmission. Note the position of the valve when
opening or closing.
1. Bypass valve
3. Rotate the bypass valve 90° (1/4 turn) back before
starting the engine. Do not exceed 5-8 ft.-lb.
(7-11 N·m) torque to close the valve.

Jacking Points

• On the front of the machine on the frame on the
inside of each drive tire
• On the rear of the machine at the center of the axle

Tie Downs

• On each side of the frame under the front steps
• The rear bumper

Operating Characteristics

Practice driving the machine because it has a hydrostatic
transmission and its characteristics are different than
many turf maintenance machines. Some points to
consider when operating the traction unit, cutting
units, or other implements are the transmission, engine
speed, load on the cutting blades or other implement
components, and the importance of the brakes.
To maintain enough power for the traction unit and
implement while operating, regulate the traction pedal
to keep the engine RPM high and somewhat constant.
A good rule to follow is to decrease the ground speed
as the load on the implement increases, and increase the
ground speed as the load decreases.
Therefore, allow the traction pedal to move backward
as the engine RPM decreases, and depress the pedal
slowly as the RPM increases. By comparison, when
driving from one work area to another, with no load
and cutting unit raised, have the throttle in the Fast
position and depress the traction pedal slowly but fully
to attain maximum ground speed.
