About the Allis-Chalmers D12

Allis-Chalmers introduced the D12 in 1959 as part of the new D Series. It was a compact row-crop tractor with a four-cylinder gasoline engine, four-speed transmission, live hydraulics, and a 540-rpm PTO. A D12 High Clearance version was also offered for cultivation work where extra clearance mattered.

The D12 stayed in production through 1968 and went through Series I, Series II, and Series III updates during that run. Early and later tractors can therefore differ in engine parts, air-cleaner parts, electrical equipment, and other details, even when both are called a D12. The serial number is the best starting point when checking parts.

Serial Number Reference

Serial number locations: The tractor serial number is stamped into the flange where the engine and transmission meet on the left side of the tractor. The engine serial number is on the rear left-hand side of the engine block behind the carburetor.

The table below shows the beginning tractor serial number for each Model D12 year and series:
