An ongoing project. Our goal is to be done shortly. Basic operations operate at A.T.M. The standard trailer hitch is functional. A.T.M., the three-point hitch is not functional. There is now a stand-in for the steering wheel while it is still being built. The front wheels turn, but they are not fully on the axle as they should be since the front axle is still being worked on.
With a 262 cubic inch, 6-cylinder engine that could be powered by gasoline, LPG, or diesel, the 1964 Allis-Chalmers D19 was a 70 horsepower, 5-plow tractor that was the first in the industry to include a turbocharged diesel engine option. Important features include a 102.3-inch wheelbase, an 8-speed gearbox (4-speed with Power Director), and a typical operating weight of around 6,700 lbs.
