Therefore, a space for arranging the battery 57 having a relatively large weight and a large size can be easily secured relatively behind the body 2, and the maintenance of the battery 57 can be performed in the battery space (space S) by a cover. This can be easily performed by attaching and detaching the plate 45.

Since the space S is located relatively behind the fuselage 2, the battery 57, which is a heavy component in the components of the combine, is arranged behind the fuselage 2, and the weight before and after the fuselage 2 is large. The balance is improved, and it is possible to prevent a bad influence on traveling due to a front heavy (a large load on the front side of the body 2).

Although the frame 4a of the threshing unit 4 has an integral structure except for the collecting funnel 28, the dust upper cover 54, and the side plate 52 as described above, the collecting funnel 28 and the dust upper cover 54 are removable. For this reason, by removing the collection funnel 28, removing the battery 57, and removing the dust upper cover 54, the sorting unit 51 (dust exhausting portion) is exposed at the top, thereby maintaining the sorting unit 51, especially the dust exhausting portion. Can be easily performed. Further, a collection funnel 28

During the cutting operation, the position of the cutting device 26 can be made to correspond to the grain culm length to be cut, and the cutting operation can be performed efficiently according to the culm length. Alternatively, the cutting device 26 can be slid toward the dust chamber 31 and stored at a storage position where at least a part of the cutting device 26 enters the space S in the cover plate 45.

As a result, in the working state of the combine, as shown in FIG. 8 (a), the cutting device 26 is positioned at the working position X projecting to the side of the body 2, and the cutting of the culm is performed as usual. At the time of non-operation, as shown in FIG. 8B, the cutting device 26 is slid to the collection funnel 28 side to be disposed at the storage position Y, and the left end of the cutting device 26 is substantially covered with the cover 65 of the feed chain 21. The body width can be reduced so as to be at the same position as the left end.

As described above, as in the combine of the present embodiment, a rear operation unit 71 is provided above and behind the paddy receiving unit 16 so that the operator can operate the machine body 2 in a standing posture behind the combine, and the riding type is provided. By adopting the combine as a combine that can be handled as a walk-type combine by the rear operation unit 71, the combine can be made lightweight and compact.

That is, as shown in FIGS. 1 and 9, a driver's seat 6 is provided on the side of the pre-processing unit 3 and the threshing unit 4, and the driver's seat 6 is provided in the driver's seat 6 beside the pre-processing unit 3. The front operation unit 13 is provided with the respective seats 8 behind the front operation unit 13 and beside the threshing unit 4. In a combine of a type provided with a rear operation unit 71 for operating the aircraft 2,
The body size can be made relatively small, and the overall width is about 1.
2 m, total length of about 2.3 m, and total height of about 1.3 m can be achieved.

Thus, the combine can be more easily handled (used) on a relatively narrow farm road or a field in a mountainous area or the like, and in particular, the cutting device 26 is slid to the storage position Y to reduce the machine width. Since the combiner can be stored, the combiner can be easily loaded on a transport vehicle such as a light truck by the storage of the cutting device 6 to facilitate transportation and the like. Also, the sliding movement of the cutting device 26 improves the maintainability.
