Abstract: Tractor towed ground levelling apparatus includes an elongate cutting edge mounted on a cylindrical steel beam. The beam carries road wheels and is connected to a foldable drawbar hitched to the plough arms of the tractor. Alternatively, the drawbar may be connected to the drawbar of the tractor through a height adjusting mechanism. When folded the drawbar is nestled against the beam and can be hitched to a road vehicle. The road wheels lift when the drawbar is unfolded, lowering the beam to the ground. The beam has a skid bar that skids over the ground in use. The cutting edge is mounted close to the skid bar and positioned so that its ground engaging edge is level with and parallel to the skid bar. The cutting edge is lifted or lowered by the plough arms or the height adjusting mechanism.
