The springs are under tension.
Use caution when adjusting them.
3. While relieving the spring tension, remove the bolt
and locknut securing the spring actuator to the
bracket (Figure 41).

4. Move the spring actuator to the desired hole
location and secure with locknut.
5. Repeat the procedure on the remaining spring.
Adjusting the Lift Arm Turn
Around Position
1. Position the machine on a level surface, lower the
cutting units, stop the engine, engage the parking
brakes, and remove the key from ignition switch.
2. The lift arm switch is located underneath the
hydraulic tank behind the front right lift arm
(Figure 42).
3. Loosen the switch mounting screws (Figure 42) and
move the switch down to increase the lift arm turn
around height or move the switch up 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 by
actuating the bypass valve in the variable displacement
hydraulic pump and pushing or towing the machine.
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.
1. The bypass valve is located on the left side of the
hydrostat (Figure 43). Rotate the bolt 1–1/2 turns
to open and allow oil to bypass internally. Because
fluid is bypassed, the machine can be moved slowly
without damaging the transmission.

2. Close the bypass valve before starting the engine.
However, do not exceed 5-8 ft.-lb. (7-11 N·m)
torque to close the valve.
