ラツプルソーの操作装置。[Scope of Claim for Utility Model Registration] (1) A grapple saw is attached to the tip of a work attachment of a work vehicle, and the saw of the grapple saw is rotatably driven by a hydraulic motor, and one side of the downstream side of the hydraulic motor is connected to a saw feed cylinder. A feed pipe line is set, and the other side is connected to an oil tank through a constriction part, and the pressure oil on the downstream side of the hydraulic motor is applied to the saw feed cylinder to feed the saw into the cut and to cut the gripped wood. In a grapple saw designed to perform ball cutting work, electromagnetic switching valves are interposed in the feed pipe and the pump discharge pipe for driving the hydraulic motor, respectively.
In addition, a switch that can be switched in multiple stages is provided in the electric circuit, and the switch is connected to each solenoid of the above-mentioned electromagnetic switching valves, so that when the operating lever of the above switch is operated to the on position, the saw is rotated, and the above-mentioned When the operating lever is operated to the down position, the saw is rotated and lowered, and when the operating lever is released at the lowered position, the lever returns to the on position and the saw is rotated and raised, and then the saw is turned off from the lowered position. An operating device for a grapple saw, characterized in that by returning the operating lever to the position, the saw is raised while stopping its rotation. (2) In the operating device for the grapple saw described in claim 1 of the utility model registration claim, a switch communicating with the solenoid of the electromagnetic switching valve is provided near the grip of the operating lever for operating the operating attachment for the operating vehicle. A grapple saw operating device characterized by:
