A mowing blade plate 3 is provided at the tip of this holding arm 4, and the holding arm 4 is provided so that the mowing blade plate 3 can be swung horizontally from side to side by an oscillating drive device 5 provided on the front side of the mower body 2. When the mowing blade plate 3 is divided into the longitudinal direction Y-Y' line of the holding arm 4 and the x-x' line perpendicular thereto when viewed from above, the outer edge of the blade is approximately 1/4 of an arc, which corresponds to the range YX'. At the same time, a guide rod a is arranged slightly above the blade surface, and a stroke rod is connected to the Y-Y' line side end of this guide rod a along the Y-Y' line. , hold this guide rod a and sweep the rod with arm 4
Alternatively, the present invention relates to an oscillating mower characterized by being fixed to the mowing blade plate mounting cylinder 24 by an appropriate means.
草刈刃板３が左回転の実施例について説明する。 An embodiment in which the mowing blade plate 3 rotates counterclockwise will be described.
実施例のように保持腕４の取付位置を草刈機体２の前進
方向に対して右側に取り付ける方が望ましく、首振り装
