Abstract:
Apparatus is disclosed which provides automatic height control for the header of a multi-row crop harvester. The crop processing header has a series of row dividers hinge mounted along its front edge. Under at least two of the row dividers is a ground engaging wheel which causes the leading edge of each to float up and down as the terrain changes. Servo actuating sensors mounted between the divider and the header respond to changes in the angle of attack therebetween. The servo system actuates hydraulic valves allowing oil pressure to automatically raise and lower the header. This means of height control maintains the cutter bar or ear stripper plates a predetermined distance above ground regardless of changes in terrain.
