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.
A soil cultivating implement comprising a frame and a plurality of soil working cultivating members mounted adjacent one another on said frame, said cultivating members being rotatable about corresponding upwardly extending axes and being spaced apart to work on both sides of a row of plants, at least one crumbler-roller connected to said frame and positioned at the rear of said members to engage soil worked by the cultivating members between the rows of plants, said roller being rotatable about an axis extending transverse to the direction of travel and having adjusting means that is settable to expand and contract the working width of that roller in that direction, said roller comprising two supports and said supports mounting respective elongated elements that form a ground engaging periphery of said roller, at least one of said supports being displaceable along the rotary axis of said crumbler-roller to expand and contract said working width, said one support being mounted on a shaft and the other support being mounted on a tube, said shaft being slideable in said tube.
