Abstract: A crop engaging rotor for conveying and/or conditioning crop comprises support members and a plurality of outwardly extending crop engaging elements. Each crop engaging element comprises an elongate strip of stiff resilient synthetic plastics material folded to form two outwardly extending arms generally in a V-shape. The folded strip is secured to a first flange of a channel-section transverse mounting bar which forms part of the rotor. The arms of the conditioning element protrude through openings in the support member which provide guide surfaces and, which maintain the folded strip in the V configuration against the outward bias of the arms. The arms are yieldable to move rearwardly under excess load conditions by a rocking movement about the bolt and by sliding movement of the arms along the guide surfaces.
