ABSTRACT:
An implement mounts a row of rotatable members, having resilient tines, that are rotatable about upwardly extending shafts. The frame portion is pivoted to a forward coupling member at several points, a lower one of which is a shear pin that allows the frame portion to tilt upwardly about an axis defined by two upper pivots upon overload of a tined member.
