Variable feeder and header drive system for an agricultural harvesting machine

摘要

A system for controlling the speed of a feeder and header drive of a harvesting machine at a varying ratio to ground speed as a function of an operator inputted signal and the ground speed. The system utilizes a sensed ground speed of the harvesting machine, a sensed feeder and header drive speed, and a speed control input from an operator, for controlling a feeder and header drive control for controllably varying the ratio of the feeder and header speed to the ground speed as a function of the operator input and the sensed ground speed.
