Title: Soil cultivating implements

Abstract: An implement has rotary soil-working cultivating members with tines that are arranged to work a broad path of soil. The cultivating members are rotated about upwardly extending axes by a drive from a p.t.o. and are positioned adjacent one another. A beamed support at the front of the implement frame has soil arresting elements fastened to the support and the elements can be tines, strips or the like that extend horizontally above the tines and below the main frame portion to free ends. The elements are positioned to arrest the lateral and/or forward displacement of soil thrown by the cultivating members. Soil crumbling members can also be attached to the frame portion in front of and between neighboring cultivating members. A supporting roller having a periphery formed by elongated rods is positioned to the rear of the cultivating members.
