PROBLEM TO BE SOLVED: To provide means supporting a residual-culm processing device with respect to a traveling car body in a state having no possibility of deteriorating a sealing performance in a hydrostatic drive system of a lifting/lowering drive device, the residual-culm processing device shredding the residual culm after corn crops have been harvested from the standing culm.SOLUTION: The corn harvesting machine includes: a culm processing device 5 for shredding culm parts after the crops have been harvested a lifting/lowering drive device 8 capable of changing the vertical position of the residual-culm processing device 5 with respect to a car body frame 10 and a fixing mechanism 9 supporting the residual-culm processing device with respect to the car body frame 10 so as to fix the residual-culm processing device 5 at a lifted position separated from the ground.COPYRIGHT: (C)2015,JPO&INPIT【課題】植立する茎稈部分からトウモロコシ作物を収穫した後の残稈の細断を行う残稈処理装置を、駆動昇降装置の油圧駆動系におけるシール性能の劣化を招く虞の少ない状態で、走行車体に対して支持させる手段を提供する。【解決手段】収穫物が収穫された後の茎稈部分を細断処理する残稈処理装置5と、残稈処理装置5を車体フレーム10に対して上下位置変更可能な昇降駆動装置8と、残稈処理装置5を地面から離れた上昇位置で固定するように、車体フレーム10に対して支持させる固定機構9とが備えられている。【選択図】図4
