ABSTRACT:
A rotary cutter includes: an elongated polygonal shaft that defines a rotation axis, that has blade-mounting surfaces parallel to and surrounding the rotation axis, and that is formed with blade-aligning studs for aligning a blade, the blade-mounting surfaces being equidistant from the rotation axis, two adjacent ones of the blade-mounting surfaces defining an angle therebetween, the angles defined by the blade-mounting surfaces being equal; blade-fastening plates, each of which is attached to and cooperates with a respective one of the blade-mounting surfaces of the shaft to define a blade-receiving gap therebetween for receiving the blade; and fastening screws for fastening the blade to the respective one of the blade-mounting surfaces of the shaft.
