COMBINE

To provide a combine capable of reducing a feeling of discomfort of an operator by increasing an actual travelling speed of a travelling device up to a set travelling speed set by a speed change lever.SOLUTION: A continuously variable transmission for executing acceleration and deceleration of output rotation of an engine and switching of rotation directions is disposed on the downstream side of a first transmission route of the engine; a travelling device 2 and a reaping device are disposed on the downstream of a transmission route of the stepless speed variator; a thresher is disposed on the downstream side of a second transmission route of the engine; and a speed change lever for operating the continuously variable transmission, and executing acceleration and deceleration of a set travelling speed V of the travelling device is disposed on a side panel of a steering part. When a speed difference S between the set travelling speed of the travelling device and the actual travelling speed v of the travelling device is greater than a predetermined speed difference SA, drive means for rotating a trunnion shaft of the continuously variable transmission is driven on the basis of the speed difference, and the travelling speed is changed. Speed change based on the speed difference is executed only when the set travelling speed is lower than the travelling speed in road travelling.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】エンジンの第１伝動経路の下流側にエンジン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を設け、無段変速装置の伝動経路の下流に走行装置２と刈取装置を設け、エンジンの第２伝動経路の下流側に脱穀装置を設け、操縦部のサイドパネルに無段変速装置を操作して走行装置の設定走行速度Ｖの増減速を行う変速レバーを設け、走行装置の設定走行速度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、速度差に基づいて無段変速装置のトラニオン軸を回動させる駆動手段を駆動させて走行速度を変速させる構成とし、路上走行中においては設定走行速度が走行速度より小さい場合にのみ速度差に基づく変速を実行する。【選択図】図１０
