1. Switch
3. Loosen the switch mounting screws (Figure 37) and
move the switch up to increase the lift arm turn around
height or move the switch down to decrease the lift
arm turn around height. Tighten the mounting screws.
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
3-4.8 km/h (2-3 MPH) 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 38). Because fluid is bypassed, the machine can
be slowly moved without damaging the transmission.
Note the position of the valve when opening or closing.

3. Rotate the bypass valve 90° (1/4 turn) back before
starting the engine. Do not exceed 7-11 N·m
(5-8 ft.-lb.) torque to close the valve.

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 and cutting units are the
transmission, engine speed, load on the cutting blades and
the importance of the brakes.
To maintain enough power for the traction unit 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 cutting units
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.
Another characteristic to consider is the operation of the
pedals that are connected to the brakes. The brakes can be
used to assist in turning the machine. However, use them
carefully, especially on soft or wet grass because the turf
may be torn accidentally. Another benefit of the brakes is to
