A cylindrical turf treatment rotor (10) adapted to be driven in rotation about a horizontal axis (10a), and provided with wear-resistant teeth (13) extending along one or more helical tracks (14a-14d) on the rotor, the teeth being individually attacked to the rotor so as to be capable of individual removal for replacement or refurbishing or for reconfiguring the rotor.
