ABSTRACT:
A wheel tractor that includes facilities for skidding logs and a loading assembly by which the logs may be loaded onto a truck. The wheel tractor includes an upright log skidding arch at a rearward end thereof. Winchlines are played out over rollers provided with this arch to be attached to felled trees. Felled logs are attached to several separate winchlines or choker assemblies. The engaged logs are skidded by the tractor to positions adjacent the rearward tractor end. The tractor then skids the logs to a truck loading area. The logs are unhooked from the winchlines and the integral loader assembly is operated to load the logs onto a waiting truck. The loading assembly includes a framework that mounts to the rearward tractor framework astride the upright arch. Loading boom members are mounted to the loader framework. They include grapples at outward free ends that operate to hold logs while the boom members are raised and lowered by a pair of boom operating cylinders. The complete loader assembly is mounted clear of the arch and winchlines when in operation.
