An arm cylinder drives the arm. A direction control valve operates the arm cylinder by allowing supply of a hydraulic oil to the arm cylinder as a spool moves. An oil path is connected to the direction control valve. A pilot oil for moving the spool flows through the oil path. A proportional solenoid valve for arm excavation is provided in the oil path. An arm control member is provided for an operator to operate drive of the arm. An amount of operation of the arm control member is equal to or smaller than a prescribed value in a first operation state and greater than the prescribed value in a second operation state. A command current instructing an opening of the proportional solenoid valve for arm excavation is set to a constant value in the first operation state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Work vehicle","description":"A work vehicle includes an arm.
