In apparatus comprising a rotor (30) and co-operating crop guide means (21), for selectivey harvesting from uncut crops wanted plant parts by combing through the crop with resilient crop engaging elements (1) projecting outwardly from a rotor core structure (32), the inner and outer regions of elements (1) are particularly prone to wear, damage and distortion. By adapting mounting members (11) and/or clamping means (14), made of stiffer and/or more durable material than is provided in the intermediate yielding region of crop engaging elements (1), stronger and more convenient mounting of crop engaging elements may be provided and the shape of the important inner crop engaging profile protected. Alternatively or additionally protection of the susceptible regions, including the distal region of elements (1), may be provided by durable inserts embedded partly or wholly in the material from which resilient crop engaging elements are made.
