The manufacture test: what tractors were built in South Bend?

1890 – 1960, the tractor-building decades, and after

The search, and what it found: The standard roster of the industry, C. H. Wendel's Standard Catalog of Farm Tractors 1890 to 1960, works through more than 900 tractor makers; its Indiana seats are Indianapolis, La Porte, Anderson, Richmond, and Mount Vernon. No production farm-tractor marque was ever seated in South Bend — that part of the test is negative, and it is printed at its true size. But the test run for this section did not stop at the production rosters, and the rest of the record is not empty. Two documented cases of tractors built in this city stand behind this section. First: the Oliver Chilled Plow Works, this city's own plow maker, designed and built a tractor of its own in the late 1920s — about twenty machines, distributed across the country, on the company's own history — before the 1929 merger absorbed the experiment. Second: from 1946 to 1986 the Pond family's Wheel Horse company designed and built its garden tractors in South Bend, a forty-year production run by any measure, which the standard farm-tractor rosters pass over because its machines were garden tractors, a class the farm-tractor catalogs do not work. The city directories worked for the Business Owners Roster (Farr's of 1883, Johnson's of 1902–03, Polk's of 1921, 1949, and the later alphabetical passes) name implement manufacturers and implement dealers here across the whole period and no farm-tractor manufacturer; the two building cases rest on the companies' own records, not on directory claims.

The ancestors test: Before the gasoline tractor, the heavy field power was the steam traction engine, and the standard lists of traction-engine builders seat Indiana's makers at La Porte, Richmond, Columbus, and Mount Vernon — no South Bend builder. What South Bend built for the steam age's harvest was the rig's stationary half and the horse-drawn half: Birdsell's clover hullers and the chilled plows of four competing works, told in the Businesses and Business Gaps records and pointed to in the implement entry below. No steam traction engine is documented as built in this city.

The word traps, printed so no reader trips on them: The city's biggest vehicle maker built no farm tractor: Studebaker's wartime tracked machine, the Weasel, was a military cargo carrier, and its trucks and cars belong to the Automobiles record. Bendix built brakes, carburetors, starters, and aviation instruments here — tractor components at one remove, never a tractor; the Technology record owns that geography. And after 1929 the name "Oliver" on a tractor means Charles City, Iowa, wherever the company's plows were cast — the boundary entry below prints that in full.
