[Problems to be solved by the invention]
Each of the side covers has a bulge (bulging portion) on the entire side surface of the side cover for the purpose of avoiding contact between the side cover and the structure on the side of the mowing portion covered by the side cover. For this reason, the view of the driver of the combine is obstructed by the bulging portion, so that the visibility of the side surface of the mowing portion is reduced, and the maneuverability of the combine is reduced.
[0007]
If the side cover is divided into an upper side cover part and a lower side cover part, the bolts must be removed each time it is necessary to remove all side covers, such as when combining and servicing. This will reduce the workability of maintenance.
[0008]
In the case where the dustproof cover is provided above the mowing portion, a fixed cover of the dustproof cover (the fixed cover body in Patent Document 3 and the fixed cover in Patent Document 4) is integrally formed from the front side to the side surface of the driver's seat. Therefore, the number of mowing lines changes depending on the type of combine, and the width of the mowing portion (in the present specification, refers to the horizontal dimension of the combine; when referring to the longitudinal dimension of the combine, referred to as the length). Processing must be performed each time, and processing of the dustproof cover becomes complicated.
[0009]
In view of the above circumstances, the present invention improves the driver's visibility around the reaper, facilitates maintenance work on the front reaper, facilitates processing of the dustproof cover, and reduces the width of the reaper. An object of the present invention is to provide a combine that can be used as a side cover regardless of the case.
