ABSTRACT:
A crop engaging rotor for conveying and/or conditioning or otherwise treating crop comprises support members 12 and a plurality of outwardly extending crop engaging elements 11. Each crop engaging element 11 is made of stiff resilient synthetic plastics material and forms two outwardly extending arms 21 and 22 generally in a V-shape. The element 11 is secured to a flange 14 or 14A of a transverse mounting bar 12 which forms part of the rotor. The arms 21 and 22 are yieldable to move rearwardly under excess load conditions by a rocking movement about the bolt 23. The element 11 is prevented from rotating about the bolt 23 by abutment of the leading edge surfaces of the arms 21 and 22 against the inner surface of the upstanding portion 14A of the member 12, by abutment of the base of the element 11 against the base flange 14 of the member 12.
