H-DS (Hydro Dual Speed) Lever : For HST
The H-DS lever (1) is located on the left of the
steering.
When the H-DS lever (1) is operated, signals are
sent to the ECU.
When the H-DS lever (1) is pulled up, the HST motor
is changed to the "Hi" side.
When the H-DS lever (1) is pushed down, the HST
motor is changed to the "Lo" side. When the HST motor
is set to the "Lo" side by means of the H-DS lever (1), it
is not automatically changed to the "Hi" side even if the
HST mode is set to the automatic transmission mode.

(4) Sensors
Fuel Level Sensor
This sensor (1) is designed to detect the fuel level in
the fuel tank. It detects the position of the float that
moves according to the quantity of fuel through the
variation in resistance of the variable resistor in order to
indicate the fuel level on the electrical instrument panel.
When the fuel has got shorter than approx. 6 L (1.5
U.S.gals) or so, the fuel level indicator and the message
appears on the electrical instrument panel.

Coolant Temperature Sensor
This sensor (1) is designed to detect the temperature
of coolant. It employs a thermistor, and detects the
variation in resistance due to a change in temperature to
indicate the temperature on the electrical instrument
panel. It also sends a signal to light up the alarm lamp in
case of overheat, and indicate an alert message.

Traveling Speed Sensor
This sensor (1) is mounted at the right bottom of the
transmission case, and generates pulses proportional to
the rotating speed and the number of teeth of the
front-wheel drive gear on the PTO drive shaft. The speed
of the tractor is calculated by means of using the
frequency of the pulse and the operational coefficient
preset for the model and tire size in question.
