We are proud to present the remarkable antique tractor collection of Harold Scherer, a lifelong tractor enthusiast whose passion extended far beyond collecting. Harold dedicated countless hours to finding, restoring, maintaining, and pulling antique tractors, becoming an active member of several tractor-pulling and collector organizations along the way.

His collection primarily showcases John Deere two-cylinder tractors, reflecting his appreciation for these iconic machines, while also featuring a diverse selection of tractors from other manufacturers. In addition to the tractors themselves, Harold assembled a vast collection of parts and components.

A true hands-on enthusiast, Harold especially enjoyed the challenge of rebuilding magnetos and carburetors, preserving the mechanical character and functionality of the machines he loved.

This auction offers a unique opportunity to experience and acquire pieces of Harold’s collection—a testament to his dedication, knowledge, and passion for antique tractors. We are honored to present his collection for your viewing and invite collectors, enthusiasts, and fellow tractor lovers to take part in this special offering.

This is the first of his three auctions, the other two auctions can be found here:
