ABSTRACT:
A cultivating implement includes a row of cultivating members, such as resilient tines or tined rotors, and a soil crumbling member positioned at the rear of the cultivating tines. A driving transmission, including eccentric weights or discs, is interconnected to supports which mount elongated, horizontally extending elements of the crumbling member and the elements are moved relative to the frame in a non-horizontal direction to perform reciprocatory and/or vibratory movements against the soil previously worked by the tines. The supports are pivoted to the frame either by forwardly extending arms or by flexible brackets which, in effect, pivot when acted on by the eccentric transmission.
