Abstract: A plant guard for a cultivator having cultivator elements mounted on a horizontal rotating shaft. The guard comprises a U-shaped member, as viewed in plan, having a vertical, plate-like base which extends transversely of the direction of travel and is connected to rearwardly extending side members which extend alongside and are pivotally connected to opposite ends of the shaft. Downward movement of the base member is limited with the base member being movable to selected vertical positions.
