The Allis Chalmers D-21 was the last of the D series tractors. It brought Allis into the big tractor market.

The D-21 Series I was the first Allis Chalmers farm tractor with over 100 HP, 103.06 HP PTO and 93.09 HP on drawbar. The D-21 Series II had a turbocharger to boost power to nearly 128 HP. It had 28% more power than the Series I but burned only 7% more fuel.



The D-21 was the first A-C tractor with hydrostatic steering with a tilt steering wheel that also tilted the instrument panel for better viewing while standing. It could run nearly 10 hours at 75% load on a tank of fuel.

To see a beautiful D-21 with the five bottom plow in action be sure to visit the Upper Midwest A-C Collectors Club show Saturday and Sunday, July 22 and 23, 1995, at the Edwin and Larry Karg farm four miles west of Hutchinson, Minnesota on Highway 7.
