Patent ID: 7975460

Claim:
A stabilization system for use with a crop harvesting header comprising: a frame carrying a structure movable about an endless path to deliver a crop to the header, the frame having opposed ends and pivotably connected to the header, each end of the frame independently movable between a first angle between the frame and the header and a second angle between the frame and the header; a housing having a longitudinal axis, wherein the housing has an inner surface; a member positioned in the housing, the member having an inside surface connectable in substantially non-rotational contact to a first structure of one of the frame or the header, and an outside surface positioned against the inner surface of the housing and connectable in substantially non-rotational contact to a second structure of the other of the frame or the header, wherein the inner surface of the housing is configured to gradually taper toward and away from the member along the longitudinal axis; wherein in response to rotational movement of the first structure in substantially non-rotational contact with the inside surface, there being rotational movement of the first structure with respect to the second structure in substantially non-rotational contact with the outside surface, the member and the housing cooperate to provide a stabilizing torsional force between the frame and the header between the first and second angles.
