<p>Power take-off control apparatus (30) which automatically shifts a vehicle speed range transmission (32) into neutral whenever a power take-off mechanism (33) is engaged to prevent accidental engagement of a drive gear while the power take-off mechanism (33) is in use. A piston (48) is moved in response to fluid pressure to shift the speed range transmission (32) between high and low speed gear ranges. The power take-off mechanism (33) engages in response to fluid pressure from a control valve (35). Whenever fluid pressure is applied to engage the power take-off mechanism (33), the fluid pressure moves the piston (48) to an intermediate neutral position to disengage the vehicle drive.</p> |
