The earliest International Harvester Company tractors are in short supply today, and this Type D 25-hp is one of about two dozen such machines known to exist. The machine weighs about 8 tons, and is powered by a 25-horsepower single-cylinder engine that fires only once every 20 revolutions. The tractor has a gear forward and gear reverse drive, and top speed is in the 3 mph range. This machine came from a collector in Washington State, who restored it in the early 1980s and then left it outside. Wearing rust and bad paint, the tractor passed through the hands of two other collectors before landing in the stable of Louis Buice, who had it restored by Wendell Kelch. Kelch tore it down completely, and rebuilt it top to bottom. The tractor is probably the cleanest Type D in existence, and is also a surprisingly quiet, easy to manage machine.
