PROBLEM TO BE SOLVED: To simplify a structure and improve operability by dispensing with a sliding structure in a ground operation tool, and further, prevent rotational turning of the ground tool unless the ground operation tool is operated for a traveling operation outside the vehicle.SOLUTION: A ground operation tool 10 can freely changes an attitude among: a storage attitude where a handle part 48 is erected along the front end of a traveling machine body 2; an operation preparation attitude where the handle part 48 is rotationally turned forward from the storage attitude; and a traveling operation attitude where the arm part 47 is rotationally downward turned according to the depressing operation of the handle part 48 in the operation preparation attitude. The ground operation tool includes, between the handle part 48 and the traveling machine body 2, a locking mechanism 63 that restricts the downward turning of the arm part 47 and the forward turning of the handle part 48 when the depressing force is applied to the handle part 48 in the storage attitude. |
