Abstract:
A crop harvesting header comprising:a frame for mounting on a crop harvesting machine for movement across ground carrying a crop to be harvested, the frame defining a working width of the header;a table mounted on the frame across the width of the header for receiving the crop when cut for transportation along the header;a cutting knife along a front edge of the table for cutting the crop;and a pickup reel comprising:a rotatable main elongate beam extending along the header generally parallel to the cutting knife;a plurality of elongate bats mounted at angularly spaced positions around the main elongate beam for rotation therewith;at least two reel support arms spaced along the width of the frame, each having a rear end mounted on the frame for vertical pivotal movement providing adjustment for raising and lowering the reel relative to the cutting knife and a forward end for supporting the main elongate beam;the main beam being mounted on beam support members each carried on a respective one of the support arms for rotation of the beam relative to the support members about a main longitudinal axis thereof;the beam support members being mounted on the support arms for sliding adjustment movement forwardly and rearwardly on the support arms so as to adjust the horizontal position of the beam relative to the cutting knife;each support arm having a wall thereof with a plurality of longitudinally spaced holes therein;and each beam support member having a sprocket mounted thereon which is rotatable about an axis on the beam support member, the sprocket having a plurality of sprocket teeth thereon for cooperating with the holes in the wall of the respective support arm such that rotation of the sprocket acts to drive the beam support member along the respective support arm.
