Abstract
This study designed to develop a mower which can reach to side of a tractor or inclined road side and operate weeding. The prototype consists of 4 parts; the base and turning equipment, the boom, the arm, the weeder. The hydraulic actuators were divided into two operations, weeding and operation of boom and they were controlled by electrical equipment. Weeding was very effective when pressure set up at $15{\ell}/min$ using weeding, as $2.27kg{\cdot}m$, 2,210rpm. Weeding range of flail mower was 1.1 to 2.6m from the center of turning equipment at a flat. In case of disk mower, it was 1.5 to 2m. As a result of operation test, flail mower was appropriate for weeding at fence and short weeds, disk mower was appropriate for long weeds.
