The famous prairie sod breakers and road builders started with the Twin City Forty in 1910. Working with McVicker engineering in Minneapolis five copies of this machine were made with a Minneapolis Steel & Machinery 7x10 engine, full canopy and operators cab.
The Forty was redesigned in 1911 by MS&MC to become the 40-65. Running at 500 RPM, the 7 1/4 x 9 engine was 1,486 ci. Weighing nearly 12 ton with one forward and one reverse gear, this second edition had no cab and the full length canopy was cut back materially in favor of fenders and a larger radiator

The biggest Twin City of all carries some confusion with it’s ratings and production dates. It may have been introduced between 1913 and 1915 as a 60-95 or 60-110.
* The 40-65 and 60-90 are believed to fall under these same sets of serial numbers.
