A grapple mounted rope controller and rope anchor rigging device includes a cylindrical barrel friction surface mounted to a jaw of a grapple to control a rope used in an arborist's rigging procedure. A rope attached to a load is wrapped around the rope controller to control the raising and lowering of loads. The device also includes a cylindrical barrel friction surface mounted to a fork of a grapple that has a cleat permanently affixed to hold fast a load-bearing rope for a time. The rigging tool utilizes the mobility and mass of a skid steer to provide a flexible location for rigging and a fixed mass with which to support rigging of heavy objects such as tree limbs, trunks and other weights.
