<P>PROBLEM TO BE SOLVED: To provide an agricultural working machine, in which, when an offset mechanism part swings, a gas spring works efficiently, and in which, when the gas spring is mounted in the agricultural working machine, weight increase or the increase in mounting operation can be suppressed. <P>SOLUTION: A ridge plastering machine 1, an example of an agricultural working machine, includes: a hitch frame 6 mounted in the rear part of the traveling machine body; an offset frame 11 and a link member 13 connected to the frame swingably to right and left along the direction of travel; and a rotation supporting arm 15 connected to the moving end sides of the frame and the link member 13, to form a parallel link structure with which a working part 60 is rotatably supported to the rotation supporting arm 15. A gas spring 20 connected between the hitch frame 6 and the offset frame 11 extends when the working part 60 moves from the forward working position or the backward working position to the housing position, contracts when the working part moves from the housing position to the forward working position or the backward working position, and almost fully extends when the working part moves to the housing position. <P>COPYRIGHT: (C)2013,JPO&INPIT |
