A cultivating implement includes a row of soil working members, such as tined rotors, and a driven soil crumbling member positioned at the rear of the cultivating tines. A driving transmission is interconnected to a rotatable bladed crumbling member or to supports which mount elongated, horizontally extending elements of a crumbling member, which elements are moved relative to the frame in non-horizontal directions to perform reciprocatory and/or vibratory movements. The crumbling member is driven to break up soil previously worked by the tines. The crumbling member is pivoted to the frame with forwardly extending arms and affords a rear support that can be set to regulate the working depths of the tines on the rotors. The transmission to the crumbling member is via the drive connections to the rotors which, in turn, are engaged by the p.t.o. of a tractor.
