To an old 6-foot by 12-foot trailer used to haul cut-up firewood from his woodlot, Kingsley, MI, farmer Arnold Wurm rigged a winch-pulled sliding wood panel that allows him to rear-unload the wood at the flip of a switch. Three-feet high and the width of the trailer bed, the panel bolts to a pair of L-shaped metal brackets connected to 3/8-inch-diameter steel cables that wrap around a 2-inch-diameter steel pipe at the back of the trailer. An electric motor mounted on the side of the trailer belt-drives the pipe. The panel comes back at the rate of 2 feet per minute (fast enough to keep two people busy piling the firewood). Once the load is dropped, the panel must be manually pulled back to the front of the trailer.
