
Cruise Control Switch
[Tractor Condition]
HST Pedal :
Forward
Position
Cruise Control Switch :
"Set"
and
"Increase"
The cruise control function is to keep the swashplate at the same angle on the pump side. As the result, the tractor
keeps same traveling speed. The cruise control switch, the cruise traveling speed has a function of
"Set"
,
"Increase"
,
"Decrease"
and
"Cancel"
. When the HST pedal is pressed forward, a signal from the HST pedal sensor is
communicated to the main ECU. Thereafter, a signal from the main ECU is communicated to the proportional control
valve directing oil from the regulator valve, which moves the servo piston. The speed and stroke of movement of the
servo piston is controlled by the main ECU based on movement of the pedal. With the HST pedal pressed, pushing
the front side of the cruise control switch to the second step enables the ECU to store the position of the HST pedal.
Even if the HST pedal is released, the main ECU keeps the servo piston fixed in place in the position of the HST pedal
stored by the ECU. Each time the front side of the cruise control switch is pushed to the first step (
"Increase"
), a
signal is sent to the ECU. Simultaneously, a signal is communicated from the ECU to the proportional control valve
and oil is guided from the regulator valve to the servo piston. As a result, the swashplate on the pump side inclines
towards the increase speed position and the traveling speed increases.

Cruise Control Switch :
"Decrease"

With the HST pedal pressed, pushing the front side of the cruise control switch to the second step (
"Set"
) enables
the main ECU to store the position of the HST pedal. Even if the HST pedal is released, the ECU keeps the servo
piston in place in the position of the HST pedal stored by the ECU.Each time the back side of the cruise control switch
is pushed to the first step (
"Decrease"
), a signal is communicated from the cruise control switch to the ECU and the
swashplate on the pump side is returned to the neutral side. Speed is reduced each time the cruise control switch is
pushed. If the cancel switch on the cruise control switch is pushed to the second step (
"Cancel"
), a signal is
communicated from the cruise control switch to the ECU and the cruise function is canceled.

(5) Range Gear Shift Section
The range gar shift section is located in the
differential gear case.
It changes the speed to five positions (
"L"
,
"N"
,
"M"
,
"N"
and
"H"
) by shifting of shifter gear (3) in the straight
line on bevel pinion shaft (7).
