ABSTRACT:
Power take-off control apparatus which automatically shifts a vehicle speed range transmission into neutral whenever a power take-off mechanism is engaged to prevent accidental engagement of a drive gear while the power take-off mechanism is in use. A piston is moved in response to fluid pressure to shift the speed range transmission between high and low speed gear ranges. The power take-off mechanism is engaged in response to fluid pressure from a control valve. Whenever fluid pressure is applied to engage the power take-off mechanism, the fluid pressure moves the piston to an intermediate neutral position to disengage the vehicle drive.
