Engine Oil Pressure Switch
This switch (1) is turned on when the main switch is
turned on and the engine oil pressure becomes lower
than 49 kPa (0.5 kgf/cm
light up the alarm lamp.

Alternator
The terminal L of this alternator detects a signal from
the battery charge. The alternator sends a signal for
making the alarm lamp at the IntelliPanel to light up if the
electricity charge system becomes abnormal.

Engine Tachometer Sensor
This sensor (1) is mounted at the right side of the
engine gear case, and generates pulses proportional to
the rotation of the fuel camshaft and the number of the
cam gear teeth. The engine speed is calculated from the
frequency of the pulse.
IntelliPanel is of cross coil type, and analogically
indicates by and after converting the frequency of the
engine tachometer sensor. The PTO speed is calculated
by means of using the frequency detected by this sensor
and operational coefficient preset from model to model.

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.
