ABSTRACT:
A roller for crumbling soil has round support plates arranged at spaced apart intervals along the axis of rotation of the roller. The plates are profiled with a saw-tooth configuration having folds and projections. Elongated elements, preferably bars, are fixed to the projections to extend generally parallel to the axis of rotation. The elements are T-shaped in cross section with the crossbar and upright of each T being connected to the peripheries of the plates leaving a space. The roller can be assembled by securing cross struts to the end plates, and passing the struts through the spaces. The intermediate plates are loosely held in position with the struts that bear on the peripheries of those plates. Thereafter, the bars can be welded or otherwise fixed to the plates' peripheries.
