A Tidy Allis-Chalmers HD14 from the S.E.Davis & Son collection
|No. of Cylinders||6|
The origins of the HD-14 go back to the Allis-Chalmers Model L which was petrol (Gasoline) engined. As diesels began to gain acceptance and offer advantages of lugging power, Allis fitted several Model L machines with General Motors 6-cylinder GM 6-71 engine offering 122 hp (91 kW) at the drawbar in the Nebraska tractor tests in 1940. The GM engine was fitted with a Rootes type blower (Supercharger) driven by the engine.
The HD-14 featured 132 hp (98 kW).

Production / Serial numbers Edit
Production of HD14 and the Torque Converter HD14C version was 6422 units between 1939 to 1947.
