<p>Hay making apparatus is disclosed including a rotor (18) carrying demountable rigid tynes (T) spaced about its periphery and coupled to a drive motor, preferably a hydraulic motor. The rotor comprises an annular rotor body of a resiliently deformable elastomeric material advantageously having a cross-sectional shape similar to that of a tyre for a motor vehicle with its axis vertical. The rotor has an inwardly projecting upper wall which couples the rotor body flexibly to the motor; an inwardly projecting lower wall which acts as a skid which follows undulations in the ground surface; and a vertical wall in which passages are formed for seating the tynes. In use the tynes are held in place by centrifugal force.</p> |
