A reaper is a farm implement or person that reaps (cuts and often also gathers) crops at harvest when they are ripe. Usually the crop involved is a cereal grass. The first documented reaping machines were Gallic reaper that was used in modern-day France during Roman times. The Gallic reaper involved a comb which collected the heads, with an operator knocking the grain into a box for later threshing.
Closed loop control of filling mechanisms
An agricultural harvester has a frame and a spout that is mounted to the frame. A target landing point indicates a position in a receiving vehicle where material is intended to land. A control system detects an actual landing point and automatically controls the spout based on a difference between the actual landing point and the target landing point.

Weed seed destruction
Weed seeds are destroyed in the chaff from a combine harvester by primary and secondary destructors where the primary feeds to the secondary. The secondary can use repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds in a direction centrifugally away from the rotor onto a stator including angularly adjustable stator surfaces around the axis. The primary can also use an impact arrangement of a different and simplified structure or can use another destruction modality such as radiation. The primary is mounted at a transfer device including a transverse auger which carries the chaff and weed seeds from the rear of the sieve to the secondary.
