Introduced in the early 1950s as an evolution of the Model M, the John Deere Model 40 became a compact, dependable tractor appreciated today by restorers and collectors. Restorations typically require sourcing parts from multiple dealers, salvage yards, and online communities. Values vary by condition and completeness, and diecast replicas help keep the model visible to new enthusiasts. Specific production dates, variant names, and production totals should be verified.

Why the Model 40 still matters

John Deere's Model 40 earned a reputation as a dependable, easy-to-maintain compact tractor and remains popular with small-farm owners and collectors. Many original machines still run today after decades of service - and many more survive as restoration projects or display pieces.

A short history

The Model 40 was introduced in the early 1950s as a successor to the John Deere M, with Deere aiming for more comfort, easier operation, and modest increases in power and efficiency. The 40 was built for a relatively short run before being replaced by the Model 420.

There were several variations of the Model 40 to suit different farms and tasks. Over the years the Model 40 developed a following among mechanics and hobbyist restorers because of its simple mechanical layout and widespread parts availability. 1

Restoring a Model 40 today

Restorers usually gather parts from multiple sources: original John Deere parts dealers, aftermarket suppliers, tractor salvage yards, and online marketplaces and forums. Expect to source items such as sheet metal, paint, engine and transmission components, and small hardware from different vendors. Community resources - restoration forums, Facebook groups, and dedicated tractor sites - are especially helpful for finding hard-to-locate pieces and practical advice.

Common restoration tasks include engine tune-ups, replacement seals and gaskets, brake and clutch work, and cosmetic work like repainting and replacing decals. Modern restorations often balance preserving originality with practical upgrades (safety lighting, electrical updates, or rebuilt hydraulics) depending on how the tractor will be used.

Collecting and value

The Model 40 is recognized as a 1950s classic among John Deere enthusiasts. Condition, originality, completeness, and local demand determine values; prices vary widely and have been influenced by renewed interest in small-farm equipment and vintage implements. Toy and scale models - notably diecast replicas from makers like Ertl - help keep the model familiar to new generations of fans.
