Since the cover member is provided so as to extend from the first lateral edge portion toward the straw conveying portion side, the entire area of the front portion of the cab can be covered well by the front cover and the cover member. Further, since the cover member is elastically deformable, even if the straw conveying part contacts the cover member, the cover member can be prevented from being damaged by the elastic deformation.

Therefore, the straw conveying part can be brought close to the driving part so as to avoid damage to the components.

Preferably, the first lateral edge portion is located on the opposite side of the grain/straw conveying portion, and the grain/straw conveying portion enters a region formed by overlapping the front cover body when viewed from above.

According to this configuration, since the grain/straw conveying unit overlaps the front cover in a plan view, the grain/straw conveying unit approaches the front cover. Since the straw conveying portion enters the region formed by locating the first lateral edge portion on the opposite side of the straw conveying portion, even if the straw conveying portion comes into contact with the cover member, it can be prevented from coming into contact with the front cover.
