Some times a tractor has no value and some times priceless. There are always ways to get a job done on a budget. I can move a 72'' x 14' log with my F 250 so can you. Trailers are cheap to build and modify as needed. Skidding a log to a place where they can be loaded is not difficult either. When I need to move some thing heavy I grab limbs that are straight to use as rollers under a log. Attach a cable or chain so that both sides that are being pulled stick a row of limbs in front of the log and pull away. Very large logs can be moved this way because the log is not being dragged but rolled. For loading pull your trailer along side of the log and place two ramps enabling the log to be rolled onto the trailer. Once loaded chain it down deliver it and return for more. You can pick up two HF 2500 LB winches for a $100. Place the winches about 8 to 10' apart with two cables or chains around the log spaced equally and pull side ways with the log rolling onto the trailer. There are several threads concerning this. Find a used lawnmower and mount a automotive alternator to charge the battery(s) to power your winches. There are several threads on Google with DIY lawnmower powered generator. Yes it will take some time to set up this but once done it is still yours. Thanks
