Twin Disc got its start as the "Twin Disk Clutch Company" in the 1920s and specialized in clutches for farm tractors. The company was created by a guy that worked for Wallis Tractors. Torque converters and power-shift transmissions got added as time went on. Deere used Twin Disc parts and components in many machines.

As far as Auburn goes - it started as Atwood Vacuum Machine Co., then changed to Auburn Clutch, then Dana/Spicer, etc. Deere used a lot of their components as well as others. I've read countless service bulletins from Deere Company over the years as they swapped clutch suppliers back and forth.

In the older machines, besides Auburn, Deere used many clutch and driveline parts from Rockford/Borg-Warner. Rockford was well known for their over-center, locking, adjustable clutches like used in some two-cylinder Deere crawler reversers. I've also come across a few Long clutches in Deere machines.

Some of the Deere two cylinder tractors from the 1930s used Thelander clutches.

From what I've seen, Deere buys from where ever they get the best deal and support - just like most sucessful companies. The only clutches I HAVEN'T found in Deere tractors are those made by Lipe and Hilliard - but I'm not even sure about that. The large clutch assemblies used in Deere 2520s, 3020s, and 4020s look vary similar to Lipe designs.

In years past, I have had pressure plates from the two cylinder crawlers that said Auburn-Thelander in the casting. Evidently the two became one company at some time. The whole shebang is now owned by A&I Products.
