PROBLEM TO BE SOLVED: To perform cutting work by steplessly changing the inclination angle of a swash plate (15) of a hydraulic pump (14) of a traveling hydrostatic pressure type continuously variable transmission (12) and changing the inclination angle of a swash plate (17) of a hydraulic motor (16) in a plurality of stages while branching the rotation of an engine (22) by a gear case (50) to drive a reaping part (4), a threshing cylinder (34) and a feeding conveyor (10).SOLUTION: A combine harvester is configured to input the driving rotation of an engine (22) to a traveling hydrostatic pressure type continuously variable transmission (12) for driving a travel device (3), and to a gear case (50). The traveling hydrostatic pressure type continuously variable transmission (12) is configured to steplessly change the inclination angle of a swash plate (15) of a hydraulic pump (14) and to change the inclination angle of a swash plate (17) of a hydraulic motor (16) in a plurality of stages, and the driving rotation is branch-transmitted from the gear case (50) to a reaping part (4), a threshing cylinder (34) and a feeding conveyor (10).COPYRIGHT: (C)2014,JPO&INPIT【課題】エンジン(22)の回転をギヤケース(50)で分岐させて刈取部(4)と扱胴(34)と供給搬送装置(10)を駆動しながら、走行用静油圧式無段変速装置(12)の油圧ポンプ(14)の斜板(15)の傾斜角度を無段階に変更し、油圧モータ(16)の斜板(17)の傾斜角度を複数段階に変更して、刈取作業が行なえるものとする。【解決手段】エンジン(22)の駆動回転を前記走行装置(3)を駆動する走行用静油圧式無段変速装置(12)とギヤケース(50)とに入力する構成とし、走行用静油圧式無段変速装置(12)は、油圧ポンプ(14)の斜板(15)の傾斜角度を無段階に変更可能に構成すると共に油圧モータ(16)の斜板(17)の傾斜角度を複数段階に変更可能に構成し、ギヤケース(50)から刈取部(4)と扱胴(34)と供給搬送装置(10)とへ分岐伝動する。【選択図】図3
