す。During the counterclockwise mowing work by the combine, the left running device 8 pushes the mud stepped on the running device 8 in the form of lumps. If this mud is moved toward the row of uncut grain culms located in the vicinity of the side part of the traveling device 8 on the left side, the mud will be taken into the main slicing body 7 the next time when cutting the row of uncut grain culms. . As a result, each device group of the reaping main body 7 has a problem such as clogging or damage.

容易に行うことができるものである。When the mud guide member 49 is stored, the guide frame 53 of the mud guide member 49 acts as a narrow guide, and the left uncut grain culm is the traveling device 8.
It is possible to prevent being stepped on or caught in. Further, in a state where the mud guide member 49 is slightly pulled out, that is, in a state where the support frames 52, 52 are slightly pulled out laterally from the lateral frame 50, the support frames 52, 52 are provided. Does not rotate downward and maintains a horizontal posture. In this state, the operator can easily perform the maintenance work on the upper part of the vehicle body 1 by using the guide frame 53 as a step.
