CA 2163145

A skidding grapple to move a load such as a tow of logs, over a terrain that is particularly difficult to traverse. A grapple assembly to engage the load has offset grapple arms that bypass one another when closing to encompass the load. A choke line is connected at one end to the winch line, and has first and second choke line legs that connect to the ends of the grapple arms. As the grapple arms close, the choke line legs form a noose to engage the end of the load and bear the weight of the load upon lifting of the grapple arms. A coupling releasably connects the grapple assembly to the boom. A winch line extends over the boom end, past the coupling and is connected to the grapple assembly, such that upon release of the grapple assembly from the boom, it remains connected to the tow vehicle by the winch line. Reconnection of the coupling assemblies is facilitated, since the winch line passes over the boom tip and results in alignment with the coupling assemblies as they come together.
