Inspired by a 1994 magazine
article on a 25 hp International Harvester Titan Type D tractor restored by
LeRoy Baumgardner Jr., Don Hermann set out to make a 1/8-scale model of that
same tractor.

Don, a retired farmer from Genesee, Idaho,
had purchased a metal lathe when he was discharged from the U.S. Army several
years earlier. Since then, while building several model engines, he has
definitely achieved the status of master machinist. Don’s talents with the
lathe are mainly self-taught. He is one of a unique cadre of Pacific
Northwest machinists who have developed great friendships through
the activity of building scale models. Don is a member of the Lewis-Clark
Antique Power Club, Lewiston,
Idaho.

International built the 25
hp Type D from 1910 to 1914. According to C.H. Wendel’s Standard Catalog of
Farm Tractors
, the model was originally sold as a 20 hp tractor but was
upgraded in about 1912. A single-cylinder engine was used.

Working scale model

What makes this model so
special and unique? Several things, including the fact that the unit actually runs.
This scale model gas engine runs on gasoline; the working powertrain propels
the unit across the floor at a speed of 40 feet per minute.

The model is accurate to
scale and intricate detail. Don made special efforts to convert the bar stock
metal used to fabricate parts so that they resembled the casting patterns
commonly found on machinery manufactured during the early 1900s. He purchased a
25 hp IHC Famous engine kit that fit his scale, but he fabricated all other
parts.
