ABSTRACT:
Apparatus for picking up cut crop from the ground or from a mower comprises a rotor driven so that the rotor picks up crop and carries the crop upwardly and rearwardly over the rotor. A hood extends over the front of the rotor and defines therewith a crop flow passage along which the crop is conveyed by the rotor. The hood is pivotally mounted by arms to side plates of the frame, and is movable along a predetermined path which is eccentric relative to the axis of the rotor. The hood is movable in response to and by the effect of the crop to effect automatic adjustment of the clearance at the entrance to the crop flow passage. An increased crop load moves the hood upwardly and rearwardly against the effect of gravity and optionally against a biasing spring. In other examples, only a front portion of the hood moves, and this may comprise a transverse roller suspended on a hinge above the entrance to the crop flow passage.
