PROBLEM TO BE SOLVED: To improve efficiency in weeding work, in a walking type work machine commonly used for snowplow and weeding work.SOLUTION: When revealing a snowplow state of discharging a snowfall to a front upper part or a side upper part of a work machine body 2 by raking in the snowfall by a plurality of work claws 12 while advancing the work machine body 2 and a weeding work state of mowing grass by the plurality of work claws 12 while advancing the work machine body 2, the work claws 12 are put in a normal rotation state in the snowplow state, and rake the snowfall in a descent area of a claw tip locus, and discharge the raked-in snow to the front upper part or the side upper part of the work machine body 2 in an ascent area of the claw tip locus, and mow the grass in the ascent area of the claw tip locus by putting the work claws 12 in a reverse rotation state in the weeding work state.COPYRIGHT: (C)2016,JPO&INPIT【課題】除雪作業及び除草作業に兼用される歩行型作業機において、除草作業の効率を向上させる。【解決手段】作業機本体2を前進移動させながら複数の作業爪12で積雪を掻き込んで作業機本体2の前方上方又は側方上方に放出する除雪作業状態と、作業機本体2を前進移動させながら複数の作業爪12で草を刈り取る除草作業状態とを現出させるにあたり、除雪作業状態では、作業爪12を正転状態とし、爪先端軌跡の下降領域で積雪を掻き込むとともに、掻込んだ雪を爪先端軌跡の上昇領域で作業機本体2の前方上方又は側方上方に放出させ、除草作業状態では、作業爪12を逆転状態とし、爪先端軌跡の上昇領域で草を刈り取る。【選択図】図6
