Ford Model 9N Prototype Tractor, 1939

Cotswold Cottage is from the Cotswold Hills in southwest England. The Fords were attracted to the distinctive character of Cotswold buildings, which are characterized by the yellow-brown stone, tall gables, steeply pitched roofs, and stone ornamentation around windows and doors. Several decorative additions were made to the house in England, before dismantling and re-erecting it in Greenfield Village.

Calling it his "automotive plow," Henry Ford had Joseph Galamb and C.J. Smith construct this experimental machine. It is powered by a 1905 Ford Model B engine with copper water jackets. This tractor represents either the first or, more probably, the second of several experimental lightweight tractor designs which culminated in the production of the Fordson tractor for U.S. markets in 1918.

"Combines" combine the major tasks of grain harvest: cutting and gathering the crop, threshing and separating the kernels from the chaff, and disposing of the straw. The Massey-Harris Model 20, introduced in 1938, culminated over 100 years of mechanical improvements. One driver operated the self-propelled machine, which reduced the need for hired help during the labor shortages of World War II.
