Abstract
A crop harvesting header includes a reel mounted on a pair of forwardly and downwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes angularly bats. The arms can be raised and lowered by hydraulic cylinders to raise and lower the reel. A linkage including a cable and bell crank is provided which is responsive to the forward and downward sliding movement of the main elongate beam along the support arms for simultaneously and automatically causing a raising movement of the reel support arms. The cable is slack over a rearward part of the movement so that no lifting occurs. The linkage is arranged relative to a forward and downward slope of the arms such that, over the forward part of the movement, the beam moves substantially horizontally to cause the reel to move forwardly of the knife without moving downwardly into engagement with the ground, for operating with the knife at ground level. The linkage is arranged to be readily dis-engageable by disconnecting the cable such that, when disengaged, the reel support arms are not raised as the beam undergoes the forward sliding movement for operating where the knife is raised above the ground.
