"RELEASABLE SKIDDING GRAPPLE" ABSTRACT A hydraulic grapple for a logging skidder which can be converted to a cable skidding device for purposes of laying the load, and which can be fully hydraulically integrated through a separable coupling device having two mating parts which when integrated together provide full hydraulic operations. The coupling device has a first coupling member pivotally mounted to the skidder arch and a second axial member to which the grapple tongs are connected through a pivoting bracket. A cable is anchored to the second coupling member and passes through the first coupling member. Releasable locking device is provided for locking the second coupling member to the first coupling member and elongated mechanical drive shaft is mounted for axial rotation in the second coupling member engageable by drive means associated with the first coupling member for driving a hydraulic pump on the second coupling member which in turn operates the hydraulically operated tongs.
