Abstract
A combine having a feeder housing for receiving harvested crop, a separating system for threshing the harvested crop to separate grain from residue, a residue spreader wheel spinning for expelling the residue from the combine, and a controller that controls the combine. The controller is configured to control the residue spreader wheel to continuously oscillate between a first speed less than a nominal speed and a second speed greater than the nominal speed while spreading the residue.
Claims8
A combine comprising:
- a feeder housing for receiving harvested crop;
- a separating system for threshing the harvested crop to separate grain from residue;
- a first residue spreader wheel for expelling the residue from the combine;
- a second residue spreader wheel for expelling the residue from the combine;
- and
- a controller that controls each of the first and second residue spreader wheels to continuously oscillate between a first speed less than a nominal speed and a second speed greater than the nominal speed while spreading the residue,
- wherein the controller alternately controls the speeds of the first and second residue spreader wheels such that when the first residue spreader wheel rotational speed increases, the second residue spreader wheel rotational speed decreases, and vice versa.
