Abstract
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.
Claims6
A system for controlling the speed of a feeder and header drive of a harvesting machine, comprising:
- a sensor for sensing a speed representative of a ground speed of the harvesting machine and outputting a ground speed signal representative thereof;
- a sensor for sensing a representative speed of the feeder and header drive and outputting a feeder and header speed signal representative thereof;
- a feeder and header speed control device connected to the feeder and header drive, the feeder and header speed control device being operable for receiving a speed control signal and increasing or decreasing the speed of the feeder and header drive based on the speed control signal;
- an operator input device for receiving an operator input and outputting an operator input signal representative thereof;
- and
- a controller for receiving the ground speed signal, the feeder speed signal, and the operator input signal and outputting a speed control signal to the feeder and header speed control device which will automatically vary a ratio of the speed of the feeder and header drive to the ground speed as a function of the operator input signal and changes in the ground speed.
A variable feeder and header drive system for a harvesting machine, comprising:
- a ground speed monitoring device;
- is a feeder and header speed monitoring device;
- an operator input device;
- a feeder and header speed control device connected to the feeder and header drive and operable for increasing and decreasing the speed thereof;
- and
- a controller operable for receiving a ground speed input from the ground speed monitoring device, a feeder and header speed input from the feeder and header speed monitoring device and an operator input, and outputting a control signal to the feeder and header speed control device for automatically controlling the speed of the feeder and header in a varying proportional relationship to the ground speed input, wherein the controller will automatically vary the proportional relationship of the speed of the feeder and header drive to the ground speed as a function of the operator input.
