PROBLEM TO BE SOLVED: To provide a reaping-harvesting machine equipped with a hydraulic static transmission, constituted to be able to make the machine body traveling velocity low while avoiding decrease of driving force (torque).SOLUTION: A hydraulic static transmission 7 to which the power of an engine 6 is transmitted is provided, and a hydraulic motor 7M of the hydraulic static transmission 7 is constituted to be freely speed-changeable. The power of the hydraulic motor 7M of the hydraulic static transmission 7 is divided parallelly into a travelling transmission system and a reaping transmission system to constitute to transmit the power of the travelling transmission system to the travelling device. The power of the reaping transmission system is constituted to be transmitted to a reaping part 2 and a reaping transmission 18 is equipped on a reaping transmission system.COPYRIGHT: (C)2010,JPO&INPIT【課題】刈取収穫機において静油圧式無段変速装置を備えた場合、駆動力(トルク)の低下を避けながら、機体の走行速度を低速にすることができるように構成する。【解決手段】エンジン6の動力が伝達される静油圧式無段変速装置7を備え、静油圧式無段変速装置7の油圧モータ7Mを変速自在に構成する。静油圧式無段変速装置7の油圧モータ7Mの動力を走行伝動系及び刈取伝動系に並列的に分岐させて、走行伝動系の動力を走行装置に伝達するように構成する。刈取伝動系の動力を刈取部2に伝達するように構成して、刈取伝動系に刈取変速装置18を備える。【選択図】図2
