Abstract
Disclosed herein is a mowing apparatus including: a motive power source for supplying rotating motion; a mowing head; a pair of first and second cutting disks slidably superposed with each other, each of the disks including a plurality of peripheral cutting teeth and the first and second cutting disks being oscillatably mounted to the mowing head; a mechanism for reciprocatively oscillating the first and second cutting disks oppositely with each other within a predetermined oscillating range, the reciprocatively oscillating mechanism being accommodated in the mowing head and adapted to be driven by the rotational motion supplied form the motive power source; and a mechanism for changing the mounting position of the first and second cutting disks about the mowing head in the circumferential directions of the cutting disks so that a portion to be used for mowing in the first and second cutting disks can be changed without removing the first and second cutting disks from the apparatus, the mounting position changing mechanism being adapted to be driven by the rotating motion of the motive power source.
