ABSTRACT:
An apparatus for single-handed operation in skidding logs, stumps, poles and the like. An A-frame with rearwardly-extending beam is attached to the three-point hitch of a tractor. A fluid-operated grapple, which will inherently adjust to various shapes and sizes of objects, is suspended from the rearward end of the beam. A chain, having a small amount of slack, is connected by its ends to the grapple tongs, and is rove around sleeved bolts near the draft arm attachment points. When the object to be skidded is grappled and lifted, the operator moves the tractor in the desired direction, and the chain immediately takes the towing load.
