The Allis-Chalmers 200 was introduced in 1972 as a six-cylinder diesel row-crop tractor. It replaced the older 190XT in the lineup and used power steering, an eight-speed constant-mesh transmission, and live PTO with an independent PTO option.
The 200 was built from 1972 through 1975 and was followed by the 7000 Series.
Serial number locations: The tractor serial number is stamped on the right side of the torque housing. The engine serial number is on a nameplate on the upper left side of the cylinder block.
