MOTOR - PUMP ELECTRICAL CIRCUIT

Electrical Circuit: RH Wing Mower

The electrical circuit is a pre-assembled wire harness that will control the motor functions. The harness will be used with a push pull off/on switch that prevents the tractor from being started when motor is engaged. The wire harness uses a three position toggle switch that is used to reverse the knife bar direction of travel. These switches are not part of the wire harness assembly, These switches must be connected correctly to operate correctly (See Figure 1). There is a motor control valve mounted on top of the hydraulic tank that will have two electrical solenoids connected to it. The wire harness has two plugs on one end that connects to the solenoids, one plug will have longer wire (also has White Wire) than the other and will connect to the solenoid further most from the cutter bar mount. The other plug with the shorter wire (has Yellow Wire) will connect to the first solenoid closet to the operator.

IMPORTANT NOTICE, READ: The Starter solenoid wires and the 12V power supply wire must be connected to tractor wiring, The power source wire must be connected to a power source that is only charged when the tractors key switch is in the on position. It is nessasary to connect power supply close to ignition switch, (with in 3" of switch). If power supply wire is connected direct to a power source that is charge when ignition switch is off, it will run the tractor battery down. The Solenoid wires (two Brown wires) must be connected close the tractor ignition switch, (within 3" of switch). This is required because some later tractor are using electronic monitoring of the tractor electrical system. If the solenoid wires are connected further down the line the monitoring system may detect this circuit as disconnected and cause the tractor to do different things, from engine shut down to jump out of gear. If you have electrical problems with the tractor doing strange things, check this connection.

When connecting wire harness to toggle switch the red wire MUST connect to the center post of switch, the yellow and the white wire must connect to the two outside post, it will not mater which outside post as long as one each of yellow or white wire is connect to the outer post (See Figure 1).

tion. If connected to direct power supply and push pull switch is left on when tractor is stopped and parked it will run down the tractor battery.

Push Pull Switch, Wire Harness plug will only fit one way on push pull switch to prevent it being connected wrong.
