PROBLEM TO BE SOLVED: To facilitate operation in a simple configuration and achieve compactness by using HST (Hydraulic stepless transmission) when gear changing a threshing cylinder, gear changing according to a kind of reaping products.SOLUTION: A versatile combine harvester includes a reaping pretreatment section (4) for reaping and transporting grain culm, and a threshing processing section for transporting and supplying the reaped grain culm by a transporting elevator (6) and thresh processing the reaped grain culm by a threshing cylinder (12) which is provided along a front and rear direction. The versatile combine harvester further includes an HST (18) arranged above the terminal end of the transporting elevator (6) and capable of gear changing, and a threshing cylinder transmission box (16) which is linked to the motor shaft (20) of the HST and driving while gear changing the threshing cylinder (12) via a driving shaft (19) which laterally crosses a shaft (13) of the threshing cylinder.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】扱胴を変速するに当たり、HST(油圧式無段変速装置)を利用し、刈取作物の種類に応じて変速し、簡単な構成で操作の容易化並びに配設位置の工夫によりコンパクト化を図ること。【解決手段】本発明は、穀稈を刈り取って搬送処理する刈取前処理部(4)と、刈取穀稈を搬送エレベータ(6)により搬送供給して前後方向に沿う扱胴(12)により脱穀処理する脱穀処理部を備えた汎用コンバインにおいて、前記搬送エレベータ(6)の終端側上方に位置して、変速可能なHST(18)と、このHSTのモータ軸(20)に連動されて扱胴軸(13)と直交する横方向の駆動軸(19)から扱胴(12)を変速伝動する扱胴ギヤ伝動ボックス(16)を備える。【選択図】図3
