Re: A-C SP-40 All Crop self-propelled combine
 
David, I have honestly NEVER even heard of any self-propelled Model 40 All Crop. The ONLY SP All Crop I have seen or even read about, was the Model 100. The 100 is basically a Model 90 made into an SPC, powered by a Wisconsin gas engine.

There was a Model 40, but it was only a pull-type. It was NOT the first All Crop, either. In fact, the Model 40 was a stab at the straight-through design market, after the fashion of the M-H Clipper, J.D. 10-12-A and such, but real Allis-Chalmers combine buyers wanted the TRUE All Crop with its L-shaped configuration. As a result, only a small amount of the 3' cut or so Model 40's were made. Yes, all the 40's are now sought after by collectors. http://s2.images.proboards.com/cheesy.gif

Ahah! Now that confirms BOTH of our stories. No, it was not made that way by Allis-Chalmers, but most definitely an SP Model 40! http://s2.images.proboards.com/grin.gif

Three out of only five built, is an amazing track record. I just wish one Model 10 John Deere still existed. Only ten were built. http://s2.images.proboards.com/cry.gif

allis -chalmers made the 40 pull-type only from 1938-1940. the john deere 12-a is the prototype 60 straight through machine that they tried , but it failed in the field trials and all blueprints and tooling was sold to john deere.

Everyone's small PTC's were full-width/straight-through, but only the All Crops were L-shaped and how they were successful, too! http://s2.images.proboards.com/grin.gif

sp 40
 
I have seen a picture of a sp 40 in a book somewhere. I think it was modified by a seed company for work in seed plots. Neat looking machine.

I would like to know were you got the info because I think you are completely wrong.

I think I've seen a pic of a 40 All Crop. I think it was shown in England. May have been made into a self propelled there.

Yes, there was a sp 40 all crop
 
There was a self propelled 40 all crop made.

Was it officially made by AC, well no....
It has a standard 40 with a AC "G" drive train mounted on top.
Somebody's special project, kind of neat though.

The model 40 was only a pull type. Some were made into a SP by universities for plot use. The JD 12/12A is an Allis Chalmers prototype 60 combine. It was a straight through design of the 60 all crop,but field performance didn't match the production 60. The prototype and all tooling were sold to John Deere.

From Norm swinford personally. I spent a whole afternoon talking to the gentleman at an A-C show I helped at in Davis, I'll. He also sent me pictures of the two prototypes of the two straight through machines Allis was working on in '58-'59. The new model 90 and the SP110 jd95guy.
