Abstract
A power take off unit for a motor vehicle equipped with a standard transmission is clutched using compressed air available on the vehicle. Available air pressure is monitored and a clutch interlock implemented through the vehicle electrical control system is made responsive thereto to prevent engagement of the clutch if the load is too heavy for the available air pressure.
