The handle 18 fixed to the frame 14 is formed into a shape that is easy to handle and push the mower bogie 10 by an operator. The lever 20 is attached to the frame 14 so as to be rotatable about a rotation shaft 30, and the tip of the lever 20 that is swung is rotated by the operation rod 26 of the mower 12 via the connecting arm 24. It is connected to a predetermined portion away from the shaft 22. Therefore, as shown in FIG. 3, when the lever 20 is swung to the left in the traveling direction shown by the solid line, the operation rod 26 of the mower 12 connected via the connection arm 24 rotates about the rotation shaft 22. The tip of the mower 12 is swung to the left in parallel with the ground. When the lever 20 is swung to the right in the traveling direction indicated by a two-dot chain line in the figure, the lever 20 is operated in the reverse of the above-described manner so that the tip of the mower 12 is swung to the right parallel to the ground. It is configured.

On the other hand, the mowing machine 12 has a cutting blade 36 and a driving device 38 connected via an operating rod 26.
