Abstract

A cam track adjustment mechanism for use with the pick-up reel of a harvester. A cam track is provided which is rotatably adjustable about an axis which is spaced away from the fixed axis of rotation of the pick-up reel. The two axes may be generally horizontally aligned relative to each other. Preferably, the cam track is rotatable around a point away from the fixed reel axis and generally on the horizontal plane of the rotational path, and is positioned so an arc from it to the entry and exit cam path is generally concentric. As such, tine angularity is less effected in these areas as a result of adjusting the cam track. With this type of timing or pitch adjustment, tine angularity can be changed in the crop gathering portion of the rotational path with minimized effect in the crop entry and exit portions of the rotational path.
