ABSTRACT:
A soil working member is journalled in the bottom of an elongated implement frame portion and driven to rotate about an upwardly extending axis. The member includes a horizontal support, that normally is rotated adjacent the frame portion bottom, and tines depend from the support. Each tine extends through the support to a fastening, such as a nut, adjacent an upwardly extending screen. The space between the screen and the fastening is occupied by a protective element, such as a cap or a rib, that prevents stones or other hard debris, from lodging in the space and damaging the bottom of the frame portion and/or support. Cooperating strips can be secured to the frame portion bottom to cooperate with the elements.
