ABSTRACT:
A trailed skidder vehicle driven from the power take-off of a tractor or other power driving vehicle performs the operations of a conventional skidder. The trailed skidder vehicle has an elongate structural frame supported by an axle and set of wheels at the rear end of the frame. The axle includes a differential drive for coordinated drive of the set of wheels. A load bearing superstructure arch-like support extends above the frame adjacent to the rear end. The arch support is constructed with braces on the frame for transmitting forces from a load applied at the top of the arch support to the axles. A superstructure cable bearing such as a cable roller arrangement or fairlead is mounted on the arch support for guiding and bearing a timber skidding cable. A winch is mounted on the frame forward of the superstructure arch support for extending and retracting a timber skidding cable over the cable bearing or roller arrangement. A number of structural features are incorporated for power driven operation in coordination with a tractor or other power driving vehicle. In an alternative embodiment a boom or grapple boom is pivotally mounted on the superstructure arch support with a grapple or jaw mounted at the free end of the boom for grapple skidding down timber. Grapple skidding capability may be combined with cable skidder ability on the trailed skidder vehicle with the cable bearing fairlead rollers mounted below the grapple boom on the arch support.
