A combine harvester is provided with left and right main frames that extend in the front-rear direction of a vehicle body, and a threshing device installed between the left and right main frames. The threshing device is provided with a threshing unit that performs a grain removal process, and a sorting unit that is provided below the threshing unit and performs a sorting process of sorting processed articles after the grain removal process has been performed by the threshing unit. A threshing frame included in the threshing unit is mounted on and supported by the left and right main frames, and a sorting unit frame included in the sorting unit is suspended from and supported by the left and right main frames.

Combine harvester frame arrangement

Disclosed is a shift power transmission apparatus for readily suppressing or avoiding size increase thereof. The apparatus includes an input shaft () receiving engine drive force, a hydraulic continuously variable transmission () driven by the input shaft (), a planetary power transmission section () combining drive force from the input shaft () and output from the hydraulic continuously variable transmission () for outputting the combined drive force, and an output rotary member () outputting power to a travel apparatus. The planetary power transmission section () and the output rotary member () are arranged on a side of the hydraulic continuously variable transmission () associated with an engine-coupled side of the input shaft (). The drive force is inputted to the planetary power transmission section () from a portion between the engine-coupled side and the hydraulic continuously variable transmission-coupled side of the input shaft ().
