Consists of a vertical frame (2) and a horizontal frame (3) connected in an L shape, and a foot stand (4) is attached to both ends of the horizontal frame (3).
Front wheels (5) and (5) are rotatably provided through (4), and a rear wheel (7) is rotatably provided at a rear end of the vertical frame (2) through a leg stand (6). An upright column (8) is screwed to the horizontal frame (3) so as to be movable laterally, and a suspension arm (9) that is rotatable forward and backward is suspended and supported on the column (8). A connecting tool (10) is provided at the lower end. The connecting tool (10) is for connecting the working arm (11) to the suspension arm (9) so as to be rotatable not only up and down but also left and right. If the working arm (11) is formed as a parallel link mechanism, the connecting tool (1
0) always keeps a constant angle with respect to the machine body (1) regardless of the rotation of the suspension arm (9), and the working arm (11) connected to this is the machine body (1) via the connector (10). On the other hand, it is supported so as to be vertically and horizontally rotatable, and it is easy to urge it upward by the spring (14). Working arm (1
In 1), an agricultural working machine (13) such as a manual punching machine, a seeding machine, or a transplanting machine can be arbitrarily selected for the hooking tool (12) provided at the tip so as to be detachably hooked. If the work arm (11) is biased upward by the spring (14), most of the weight of the agricultural work machine (13) at the tip of the work arm (11) is absorbed by the work arm (11) and it can be moved up and down very easily. You can The latch (12) may be arbitrarily formed according to the agricultural working machine, and is not specified in this embodiment.
