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,

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

Don’s special care in
building this model paid off. Incredibly, all of the parts fit on the first try
and not one had to be re-made. Don’s son-in-law made the decals and the wooden
base that holds the tiny Titan. The base unit includes rollers under the
wheels, so the unit can be operated in place.

Faithful reproduction

Don says the model took
about four years and “many miles” to complete. Why miles? Although the full-size
Titan restored by LeRoy Baumgardner Jr. was originally used just 60 miles
northwest of Don in St. John, Wash., by the time Don became interested in it,
it was located in Kinzers, Pa. Don contacted LeRoy and learned that the Type D
Titan nearest to Don was located in Crosby, N.D.

Don was determined to make
his model as accurate as possible, and while he was able to purchase a parts
book and operator’s manual, neither provided the dimensions and details he
required. So he went the extra mile — actually about 6,000 of them! Don and his
wife, Donna (since deceased), ended up making three trips from Genesee to Crosby to take photographs and measurements of John
Tysse’s Titan to recreate this masterpiece.

Don and his family have
donated the Titan to the Eastern Washington Agricultural
Museum, Pomeroy, Wash.,
where it can be viewed during regular hours or by special appointment. FC
