COMBINE-HARVESTER

To provide a combine-harvester capable of increasing an actual traveling speed of a traveling device up to a set traveling speed set by a speed change lever and reducing discomfort of an operator.SOLUTION: A combine-harvester is configured as follows: a stepless speed variator (20) for performing increasing/decreasing an output rotation speed of an engine (E) and switching a rotational direction thereof is provided on a downstream of a first transmission path (A) of the engine (E); a traveling device (2) and a reaping device (3) are provided on a downstream of the transmission path of the stepless speed variator (20); a threshing device (4) is provided on a downstream side of a second transmission path (B) of the engine (E); a speed change lever (16) for performing increasing/decreasing a set traveling speed (V) of the traveling device (2) by operating the stepless speed variator (20) is provided on a side panel (15) of a maneuvering section (5); and when a speed difference (S) between the set traveling speed (V) of the traveling device (2) and an actual traveling speed (v) of the traveling device is greater than a predetermined speed difference (SA), driving means (42, 43) for rotating a trunnion shaft (40) of the stepless speed variator (20) are driven to increase the traveling speed (v).SELECTED DRAWING: Figure 10 【課題】走行装置の実際の走行速度を、変速レバーで設定された設定走行速度にまで増速させ、作業者の不快感を軽減することができるコンバインを提供する。【解決手段】エンジン（Ｅ）の第１伝動経路（Ａ）の下流側にエンジン（Ｅ）の出力回転の増減速と回転方向の切替えを行う無段変速装置（２０）を設け、該無段変速装置（２０）の伝動経路の下流に走行装置（２）と刈取装置（３）を設け、エンジン（Ｅ）の第２伝動経路（Ｂ）の下流側に脱穀装置（４）を設け、操縦部（５）のサイドパネル（１５）に無段変速装置（２０）を操作して走行装置（２）の設定走行速度（Ｖ）の増減速を行う変速レバー（１６）を設け、走行装置（２）の設定走行速度（Ｖ）と走行装置の実際の走行速度（ｖ）の速度差（Ｓ）が所定速度差（ＳＡ）よりも大きい場合には、無段変速装置（２０）のトラニオン軸（４０）を回動させる駆動手段（４２，４３）を駆動させて走行速度（ｖ）を増速させる構成とした。【選択図】図１０
