Abstract

A mowing apparatus has an elongated handling rod on the distal end of which is mounted a gear unit having a casing and an output shaft which extends substantially perpendicularly to the handling rod. The apparatus further includes a first disk cutting blade mounted so as to cover the side of the casing adjacent the output shaft, and a second disk cutting blade superposed on the side of the first disk cutting blade adjacent the casing. A connecting pin interconnects the first and second disk cutting blades such that the disk cutting blades are rotatable relative to each other about their axes. An eccentric shaft is adapted to revolve about the axis of the output shaft in accordance with the rotation of the output shaft, and is received in a cam slot provided for rotation as a unit with the second disk cutting blade about the connecting pin, so that the can slot reciprocate circumferentially about the connecting pin in accordance with the revolution of the eccentric shaft. A rod-like fixing member for fixing the first disk cutting blade to the casing extends through an aperture formed in the second disk cutting blade so as not to interfere with the second disk cutting blade during relative oscillation of the second disk blade relative to the first disk cutting blade.
