• Raise either wing cutting unit to the transport
position. The cutting unit should turn off. If the
cutting unit does not stop, there is a malfunction in
the interlock system that should be corrected before
resuming operation.
• If the cutting unit is lowered again the motor should
re-start. If the cutting unit does not re-start, there is
a malfunction in the interlock system that should be
corrected before resuming operation.
• Raise the center cutting unit to the transport
position. All the cutting units should stop running
and not re-engage when lowered to the ground. If
the cutting unit does not stop when it is raised or if
it re-starts when it is lowered, there is a malfunction
in the interlock system that should be corrected
before resuming operation.
• With the cutting units engaged, switch the speed
range from low to high. The cutting units should
stop. If the cutting units do not stop, there is a
malfunction in the interlock system that should be
corrected before resuming operation.
• If the operator rises from the seat with the cutting
units engaged and/or the traction pedal out of
neutral, the cutting units must stop in approximately
one second and engine must shutdown in
approximately two seconds. If the cutting units do
not stop and the engine does not shutdown, there is
a malfunction in the interlock system that should be
corrected before resuming operation.
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.
1. Raise the seat and remove the battery cover. The
bypass valve is located in front of the battery
(Figure 28).
2. Rotate the valve 90 degrees (1/4 turn) in either
direction to open and allow oil to bypass internally.
Because fluid is bypassed, the machine can be slowly
moved without damaging the transmission.
Note: Resistance will be felt on the valve when it is
moved to the open position.
3. Rotate the valve 90 degrees (1/4 turn) back to
close the bypass valve before starting the engine.
However, do not exceed 5 to 8 ft-lb (7 to 11 N⋅m)
torque to close the valve.
1. Bypass valve access hole
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 (Figure 29)
and the reverse four-wheel drive pressure port
(Figure 30).
