The fitment for a rotating harrow comprises a counter-plate (5) which can be screwed to the tool-supporting plate (2) using the holes (23) normally used for screwing on the tools. The counter-plate has an omega-shaped recess (55) on its lower face (54), defined by an opening (554) and two lips (552, 553). A U-shaped tool with two teeth joined by a cross bar corresponding in cross-section to the recess can be fitted into it.
