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 http://www.google.com/patents/US2625001" rel="nofollow - http://www.google.com/patents/US2625001 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") http://www.google.com/patents/US2927694" rel="nofollow - http://www.google.com/patents/US2927694 A straw chopper (Different than the 60/66 spreaders you see all the time) http://www.google.com/patents/US2626159" rel="nofollow - http://www.google.com/patents/US2626159 SP-100 rear straw spreader http://www.google.com/patents/US2932145" rel="nofollow - http://www.google.com/patents/US2932145 Snap Coupler http://https://www.google.com/patents/US2834277" rel="nofollow - https://www.google.com/patents/US2834277 Those All-Crop 40 self propelled test plot combines http://dl.sciencesocieties.org/publications/aj/abstracts/43/10/AJ0430100516" rel="nofollow - http://dl.sciencesocieties.org/publications/aj/abstracts/43/10/AJ0430100516

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!

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