PROBLEM TO BE SOLVED: To provide a forestry machine in which a harvester apparatus can obtain sufficient driving force from a harvester apparatus driving start time.SOLUTION: According to one aspect of the present disclosure, the forestry machine includes: an engine a hydraulic pump which discharges hydraulic fluid by the power of the engine and a roller harvester apparatus including a hydraulic actuator for a harvester, which is driven by hydraulic fluid discharged from the hydraulic pump. The hydraulic actuator for a harvester has a rotationally driving part which performs rotationally driving, and a driving part which performs driving other than rotationally driving. The forestry machine further includes a cut-off part which cuts off supply of the hydraulic fluid to the rotationally driving part until a pressure of the hydraulic fluid rises to a predetermined pressure when rotationally driving by the rotationally driving part is selected.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2016,JPO&INPIT【課題】ハーベスタ装置の駆動開始時から十分な駆動力を得ることができる林業機械を提供すること。【解決手段】本開示の一局面によれば、林業機械は、エンジンと、該エンジンの動力により作動油を吐出する油圧ポンプと、該油圧ポンプから吐出する作動油により駆動するハーベスタ用油圧アクチュエータを含むローラハーベスタ装置と、を備え、前記ハーベスタ用油圧アクチュエータは回転駆動を行う回転駆動部と、回転駆動以外の駆動を行う駆動部と、を有し、前記回転駆動部による回転駆動を選択する場合において、前記作動油の圧力が所定の圧力に昇圧するまで、前記回転駆動部への前記作動油の供給を遮断する遮断部を設けた。【選択図】図3
