ABSTRACT:
An electrohydraulic control system for loading a bucket of an earthmoving machine includes sensors for sensing when the machine is crowding a pile of material to be loaded. A command signal generator monitors the sensed "crowd" parameters to trigger one of a learning or playback mode for hydraulic cylinder command signals when the parameter indicates pile contact.
