    The Caterpillar Model Twenty-Two track-type tractor was manufactured at the East Peoria plant from 1934 through 1939. The first spec sheet from 1934 indicated that the tractor had a 4-cylinder, 4x5-inch bore and stroke engine rated at 23.69 drawbar horsepower and 29.39 belt horsepower. It weighed in at 6,150 pounds. More than 15,000 of these tractors were built and came in both a standard 40-inch gauge and a wide 50-inch gauge. In 1934, the standard 40-inch gauge retailed for $1,450 and the wide 50-inch gauge for $1,500.

    The Twenty-Two was a versatile machine, as it was paired with a wide variety of other equipment depending on the job at hand.
