ABSTRACT:
A cultivating implement has rows of rotatable soil working cultivating members that are mounted on beams extending transverse to the direction of travel, one behind the other. The members rotate about upwardly extending axes and can be positioned along the beams to cooperate with one another and work soil between rows of plants. Assemblies of crumbler-rollers are secured to the frame and positioned to engage soil worked by the cultivating members but avoid the plant rows. Each assembly is secured by a support arm adjustably settable along the length of a beam at the rear of the frame. Each assembly is a pair or two rollers journalled on a common shaft and each roller has two supports, one of which is movable along the shaft to and from the other to adjust the width of the roller. Each support mounts bars that form the periphery of the roller.
