Abstract
An agricultural harvester having a header pivotally connected to the forward end of said harvester and said header having a flexible floating cutterbar on the forward lower edge thereof and a rotary reel mounted for automatically adjustable movement toward and from said cutterbar by power means to prevent accidental contact between the same. The harvester also includes power means to elevate the header to enable the same to effect desired spacing from the surface of a field when the contour is such as to require the same. Sensing means responsive to the surface of a field control the operation of the respective power means for said reel and header automatically.
