![]() ![]() To disengage the contactors, the operator moves the switch back to the "R" position. This connects all three windings of the motor into a circuit that powers the motor forwards. To engage the contactors, the operator moves the switch from the "R" position to the "F" position. The forward/reverse contactors are normally operated by an electrical switch located near the tractor's steering wheel. The contactors must be placed in direct physical contact with each other when connecting or disconnecting them. When the reverse contactor is activated, the power connections at the motor connect line L1 to T3, line L2 to T2, and line 元 to T1. When the forward contactor is engaged, power connections at the motor connect lines L1 to T1, L2 to T2, and 元 to T3.
