ABSTRACT:
Apparatus for picking up and conveying crop comprises a horizontal rotor driven from the top of a tractor in a sense such as to pick up crop and carry the crop upwardly and rearwardly over the rotor. The rotor comprises a main support structure and outwardly extending crop engaging elements formed of stiff resilient non-metallic material and arranged to be yieldable along the general direction of crop flow. The yielding can be due to the material of the elements or a separate biasing element, or both. Each crop engaging element is an outwardly extending fin-like element having a principal plane perpendicular to the direction of crop flow, having an outward length greater than its width transverse to the crop flow, and having side edges which converge towards each other in the outward direction. Preferably the shape includes or consists of a triangle the apex of which is truncated.
