ABSTRACT:
A clipping apparatus for bushes and grass intended to be attached to a tractor or like vehicle and comprising two rotatable blades having cutting edges. The blades are operative to produce a clipping action in co-operation with an underlying toothed means. One of the blades, when seen in the direction of movement of the apparatus, is mounted somewhat behind the other blade, and the blades are located on mutually different levels. The distance between the centers of rotation of the blades is greater than the radius of the circle defined by the tips of the cutting edges but shorter than the diameter of said circle. The blades are arranged to rotate in the same direction.
