の油圧回路。 A grapple saw is attached to the tip of the work attachment of the work vehicle, and the chain saw part of the grapple saw is rotatably driven by a hydraulic motor.On the downstream side of the hydraulic motor, one side is set up with a feed conduit leading to a saw feed cylinder, and the other side is connected to a feed pipe line leading to a saw feed cylinder. It communicates with the oil tank through the throttle part, and the pressure oil downstream of the hydraulic motor is applied to the saw feed cylinder to feed the cutting of the chain saw part,
In a grapple saw designed to perform bevel cutting work on gripped wood, a switching valve is interposed in the feed pipe, and by switching the switching valve, pressure oil from the hydraulic motor is directed to the head side or rod side of the saw feed cylinder. A hydraulic circuit for a grapple saw, characterized in that it is configured to selectively supply oil to an oil chamber.
