| First known as the "United" the Allis-Chalmers Model U was
first produced for The United Tractor & Implement Company in 1928.
On the demise of the company Allis-Chalmers continued producing
it as the Model U. Early versions were powered by a Continental
L-head side valve engine of 4.25 x 5 inch bore and stroke. From
1933 onwards Allis-Chalmers produced their own 34 hp overhead valve
four cylinder UM engine for the Model U. With reliability second
to none and an excellent reputation for power and performance very little
upgrading or modification was necessary during it's long production
life. |
