PROBLEM TO BE SOLVED: To simplify a structure and improve operability of a ground operation tool, and avoid elongation of a machine body entire length by the ground operation tool.SOLUTION: A ground operation tool 10 comprises: a vertically rotational arm part 47 extending forward from a rotational fulcrum position of a rotational operation and a pair of left/right handle parts 48 extending upward from the front ends of the arm part 47. Each handle part 48 is connected to the front end of the arm part 47 so as to rotationally turn forward/backward, and can change the attitude among a storage attitude of erecting along the front end of the traveling machine body 2, an operation preparation attitude rotationally turned forward from the storage attitude, and a traveling operation attitude rotationally turning the arm part 47 downward by being pushed down from the operation preparation attitude. The handle part 48 in the storage attitude, when viewed from a machine body front side, is circumvented as if holding a hood 60 of the traveling machine body 2, and when viewed from the machine body lateral face, located rearward of the front end of the hood 60.COPYRIGHT: (C)2014,JPO&INPIT【課題】地上操作具における構造の簡略化や操作性の向上を図るとともに、地上操作具によって機体全長が長くなることを回避する。【解決手段】地上操作具10は、回動操作の回動支点位置から前方に延出する上下回動自在なアーム部47と、アーム部47の前端部から上方に延出する左右一対のハンドル部48とを備え、ハンドル部48は、アーム部47の前端部に前後回動自在に連結され、走行機体2の前端部に沿って起立する収納姿勢と、収納姿勢から前方に回動された操作準備姿勢と、操作準備姿勢からの押し下げにより、アーム部47を下方に回動させる走行操作姿勢とに変姿自在であり、さらに、収納姿勢のハンドル部48は、機体正面側から見たとき、走行機体2のボンネット60を左右から抱えるように迂回し、機体側面側から見たとき、ボンネット60の前端よりも後方に位置する。【選択図】図6
