Abstract
A loader backhoe work machine in which a power unit is coupled to a power train through a torque convertor. The torque convertor incorporates a lock up clutch to enable more efficient operation of the work machine in a transport mode while retaining the torque multiplication feature during the loading and/or backhoe operations. The control system for the lock up clutch senses selected engine and system operating parameters to engage the lock up clutch only when those sensors indicate a transport operating condition.
