ABSTRACT:
A cultivating machine has one or more trailing rollers that support the cultivating members at the desired height. Each roller has ends that are journalled via bearings to adjustable arms and the bearings are protected by profiled hoods having rims joined to scraping elements which fit within dished screens on the roller ends. The elements remain stationary while the screens rotate and the former conduct soil away from the bearings during operation. Each roller has support plates with circumferential recesses that receive elongated peripheral elements. The arms extend upwardly to the rear and their forward ends are pivoted to a frame portion. A forward coupling trestle has rear supports interconnected to the arms.
