ABSTRACT:
A conveying system (43) is disclosed including a vertical auger (27) which receives material from a horizontal auger (25). The vertical auger is driven by a hydraulic motor (37) and the horizontal auger is driven by a hydraulic motor (35). A pressure response valve (89) responds to a pressure signal (93), representative of the load on the motor (37) driving the vertical auger to unload or bypass the motor (35) driving a horizontal auger. As the load on the vertical auger decreases, the valve (89) gradually communicates more flow to the motor (35) driving the horizontal auger, thus feeding more material (grain) to the vertical auger.
