ABSTRACT:
A mechanism for controlling the attitude of a crop harvesting header mounted on a combine base unit for movement in a generally vertical direction and for rotational movement in a generally vertical plane to permit the header to follow changes in the ground contour is disclosed wherein a sensor bar is mounted on each respective side of the center line of the header to sense the location of the ground with respect to the corresponding end of the header. The header is provided with hydraulic lift cylinders and tilt cylinders to operably move the header vertically or rotationally. The control mechanism operably interconnects the sensor bars and the lift and tilt cylinders to effect movement of the header in response to a predetermined pattern of movement of the sensor bars.
