One of the largest steam donkeys used in the Oregon woods, the Smith and Watson 12 X 13 compound geared universal yarder, was placed in service in 1915 by the Winchester Bay Logging Company. It required a crew of 25 working full time to keep it operating, including wood cutters to supply three cords of wood daily for the fire box, pipe layers and pump specialists to manage 2000 feet of water line needed to pump 3000 gallons of water for a day's steam, firemen to maintain 250 pounds of steam pressure, and engineers, drag saw cutters, and linemen to yard logs from 1/4 mile away. Although changing gears took hours, the compound geared steam donkey could yard logs more efficiently in low gear over rough and steep terrain than single speed machines. In 1938 it was retired in favor of diesel powered machinery.
