main screen, press the middle button (
icon) to adjust
the speed.
Note:
When switching between low and high ranges, the
settings will transfer based on the previous setting. The
settings are reset when the machine is turned off.
Note:
This feature may also be used in conjunction with
cruise control.
Checking the Interlock
Switches
CAUTION
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
•
Do not tamper with the interlock switches.
•
Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
The machine has interlock switches in the electrical system.
These switches are designed to stop traction when the
operator gets off of the seat when the traction pedal is
depressed. Although the engine will continue to run, it is
strongly recommended that the engine be stopped before
rising from the seat.
To check the operation of the interlock switches, perform
the following procedure:
1.
Drive the machine slowly to a large, relatively open
area. Lower the cutting unit, stop the engine, and apply
the parking brake.
2.
Sit on the seat and depress the traction pedal. Try to
start the engine. The engine should not crank. If the
engine cranks, there is a malfunction in the interlock
system that should be corrected before beginning
operation.
3.
Sit on the seat and start the engine. Rise from the seat
and move the PTO lever to On. The PTO should not
engage. If the PTO engages, there is a malfunction in
the interlock system that should be corrected before
beginning operation.
4.
Sit on the seat, engage the parking brake and start the
engine. Move the traction pedal out of the neutral
position. The InfoCenter will display “traction not
allowed” and the machine should not move. If the
engine does move, there is a malfunction in the
interlock system that should be corrected before
beginning 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.
Important:
Do not push or tow the machine faster than
3 to 4.8 km/h (2 to 3 mph) because internal transmission
damage may occur. The bypass valves must be open
whenever the machine is pushed or towed.
Note:
Apply parking brake when opening tow valves.
1.
Raise the seat. The bypass valves are located below the
front of the fuel tank (
2.
Rotate each valve 3 turns counter-clockwise to open
and allow oil to bypass internally.
Do not open
more than 3 turns.
Because fluid is bypassed, the
machine can be slowly moved without damaging the
transmission.
3.
Close the bypass valves before starting the engine.
Torque to 70 N-m (52 ft-lb) to close the valve.

Bypass valve (2)
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,
located on the hydrostat, and on the port located
in-between ports M8 and P2 on the rear traction
manifold which is located behind the front tire.
Jacking Points
There are jacking points located at the front and rear of the
machine.
