There are five key positions, OFF, ACC, ON, PREHEAT (GL) and START (ST) on the main switch as shown
above.
When the main switch (2) is set to ACC (Accessory), in case of cabin, the radio, windshield wipers (front and rear),
work lights (front and rear), cigar lighter and blower fan can be used.
When the main switch (2) is set “ON”, AM terminal of the main switch is connected to ACC and M terminals.
As a result, the battery current flows to the key stop relay (13), and the contact points of relay turned to “ON”
position, and the key stop solenoid (14) is actuating for opening the fuel supply line.
When the main switch is set to “START” under the condition that the main gear shift lever is neutral position and
safety switches (5), (6) is turned ON and PTO lever is in neutral (PTO safety switch (11) is pushed to ON).
AM terminal of the main switch is connected to M and ST terminals.
Consequently, battery current flows to safety switches (5), (6) coil of starter relay (4), PTO relay (12) (When the
PTO safety switch is set to ON, battery current flows PTO safety switch (11) and coil of PTO relay (12)).
This actuates starter motor (3).
When the main switch is released after starting the engine, the main switch returns to ON automatically.
This stops the starter motor.
Fuel supply and fuel stop to and from then injection pump are carried out by the key stop relay (13) and engine
stop solenoid (14).
In case of the hydraulic clutch operation type, the tractor is kept in safety even if the can not be disengaged.
