Therefore, in order to adjust the cutting height, if the machine frame of the XU cutting section is moved up and down relative to the machine body, the rush that is cut by the cutting blade device and transported by the conveyance device on the cutting section side will be moved closer to the cutting device side. A problem arises in that when the transfer device takes over, disturbances occur and smooth handover is not carried out. In addition, in order to solve this problem, the pickling device is transported by a transport device on the cutting section side, and since the height is short from the grass, the pickling device is carried by the transport device on the cutting section side to remove the grass. When a scouring device is combined and the casing of the scorching device is assembled and supported on the casing of the reaping section, the transportation on the reaping section side is reduced by the amount of transport equipment required for the scorching device to perform the scouring action. Since the device will be extended toward the rear of the machine, the overall length of the grass cutter's body will become longer, creating another problem that will degrade maneuverability.
