What works well for a friend of mine is a steel cable, pulley, and tongs
I don't think he can go a hundred yards but 200 feet is within his cable length
Working from a road, Dave runs the cable through the pulley tied to a roadside tree, one end of the cable on the log tongs the other attached to a tractor( a truck would work). Dave runs the tractor down the road until the log is at the road edge. Then attaches the font bucket on the tractor to the log tongs to put the log on the trailer.
1/4" cable will pull a 1000 pounds and a whole lot more before breaking. 250 ft about $40-$50
5/16 cable will pull about a ton.
