So I'm getting smart at college. I found out about this thing called "Google Scholar" (Google search it) It lets you look up patents. I just searched "Allis-Chalmers harvester" and found a ton of All-Crop/Gleaner/Forage harvester/Corn picker history. 
Here are a couple things that caught my interest. 

The wagon loader

A cool "transverse rotor" 90 All-Crop! (Or that's what it looks like to me. It says "More specifically, it is an object of the invention to provide a rotary separator mechanism")

A straw chopper (Different than the 60/66 spreaders you see all the time)

SP-100 rear straw spreader

Snap Coupler

Those All-Crop 40 self propelled test plot combines

The rotary 90 All-Crop grabs my attention more than anything. But I can't build it based on the patents, or I'd be doing what John Deere does! Ouch

I believe the patents have expired long ago as there was no reason to renew them.
