| 1. An automatic loading control system for loading an implement of a work machine with material from a pile, comprising:
a lift sensor configured to monitor a lift actuator and communicate a lift signal;
a tilt sensor configured to monitor a tilt actuator and communicate a tilt signal;
a speed sensor configured to communicate a speed signal indicative of a speed of the work machine; and
a control module configured to receive the lift signal, the tilt signal, and the speed signal and generate a control signal
to control a clutch configured to control a rim-pull of a powered wheel of the work machine based on at least one of a lift
velocity of the lift actuator, a tilt velocity of the tilt actuator, and a work machine velocity to facilitate movement of
the implement through the pile.
