The Allis-Chalmers One-Ninety was introduced in 1964 as a larger row-crop tractor while the D Series was still in production. It used a six-cylinder gasoline or diesel engine, power steering, Allis Snap-Coupler, and the Power Director system for live PTO operation.
The 190 was built through 1972 and was part of the larger tractor line that also included the 190XT. The 190 and 190XT can look similar, so check the model marking and serial number to make sure you are looking at the correct information.
Serial number locations: The tractor serial number is stamped on the left side of the tractor in the flange where the engine and transmission meet. The engine serial number is on a nameplate at the upper left side of the cylinder block.
