RARE MM G43 experimental

I have been trying to find information on an experimental tractor that my father bought back in late 1960's early 1970's. Before his passing he gave me a quick run down of the information that he had. This tractor as far as he knows is a Minneapolis Moline G43 experimental. That being said. There were only 10 made. Seven of which were sent to MM Proving grounds. The body is Minneapolis Moline, the 4WD is Ellwood, and the motor is Harnischfeger(sp). Since Harnichfeger would not sell the patent to the motor to MM, it was never put into production and therefore I can't find any more information on this tractor. Can anyone out there enlighten us with anymore information? Possibly even a value?
 
I have never heard of such tractor, but never say never in MM world. Maybe for export? Odd that a late 60's tractor would use Elwood front axle. Most all MM's by early 60's were using the Coleman axle.
 
Maybe this engine??

Interesting. I would also be interested in any photos Steve. The bottom of the photo shows Crystal Lake Il. as the address of the engine mfg. Thats not far from me and I"ve never heard of it. Bet those Fords were a real treat to drive, cabovers no less. You should have my e-mail Steve. Wonder if Il. John knows anything about that engine co., in his backyard !!!
 
I too would like to see photos of this tractor(s), I have never heard of such. by the late 1960's MM was using Clark MFWD axles, just like Sister company Oliver. ~ Marty
 
Never heard of them but I've only been in this [part of the country for 40 years. I'll write that name down and see if anyone knows about them.
 
I am Erin's brother.

The tractor utilizes a GTB rear end. The engine is a three cylinder, two stroke, water cooled, Harnischfeger 387C-18 that utilizes a rotary supercharger. Horsepower is in the neighborhood of 125-150. It has a Roosa rotary injection pump.

The tractor has a two point with which dad used to pull a 7 bottom plow with ease. It is essential to wear good hearing protection while operating it. You could easily hear that tractor for a few miles.

I believe the tractor was built in 1958. It also has a PTO as most GTBs did unless you had a wheatland version.

Its appearance is very much like a GTB as it has the same radiator, sheet metal and fenders. That's where the similarity stops. The four cylinder gas GTBs made about as much noise as a Swiss pocket watch compared to the Harnischfeger which would be compared to Big Ben sounding off.
 
Some other things come to mind...

It has a flywheel pulley, hydraulics and, if I am not mistaken, power steering.....something our GTB didn't have.

I know dad used to use the GTB to run his Joliet pull behind corn sheller, I don't know if he ever used the G43 to do so. Corn shelling was a huge part of life from Amboy to Princeton to Dwight to Elburn in Illinois. We shelled our last corn crib in 1993 but those last 10 years were with a Joliet mounted on a 1947 International truck.

I am the only one of his children to have not only ever seen the G43 running but used to spend hours in the seat with "Mickey Mouse" muffs on my head and dad standing on the deck plate doing custom plowing. Beyond that, I know my uncle, Chuck Johnson, ran it some when he was a teen ager when dad needed help. So except for he and I, I don't think there is anyone else alive who has run the tractor.
