40-80 Minneapolis

a martinson · Mar 23, 2009

This is our 1918 40-80 Minneapolis. It has a 7.5" bore and 9" stroke with an engine speed of around 550 RPMs. It has an L-Head engine. The later ones that are rated 35-70 are essentially the same tractor, but with a valve in head engine.

Gorgeous looking machine. Here's a question. Are there noticeable differences between the 40-80's and 35-70's? I am curious because there is an old Minneapolis that shows up to a show near me but the gentleman running it couldn't give me a very good answer. It is always labelled as a 40-80.

You should be very proud of yourself. A lot of people including myself would love to just drive one for the afternoon, let alone see it in their shop!

If you climb in the cab and look at the engine it is fairly easy to tell. The quickest way to differentiate is if you can see pushrods, then it is a 35-70, as the 40-80s have flathead engines.
