Curved support arm for reel assembly

摘要

A crop harvesting mechanism having a reel assembly with a reel that is rotatably supported at each end by a respective reel support. A reel carrier arm is provided for each of the reel supports and the supports are movable along the reel carrier arm. A horizontal adjustment actuator moves the reel support along the reel carrier arms over an adjustment range. The reel carrier arms are constructed with an upward or downward oriented curve, inside of the adjustment range over which the reel holding devices can be shifted by the actuator. The reel operates below a cutting bar in its forward position and in a position moved further back that is above and behind the cutting bar so that collisions are avoided.
