A highly focused private collection of classic John Deere tractors is set to go under the hammer in late June 2026, bringing a rare concentration of pre 1955 two cylinder machines to the market. The timed online auction, hosted by BML Auctions, centers on a lineup that reflects one of the most recognizable engineering eras in American agricultural machinery.
What makes this sale stand out is its purity. The majority of the tractors belong to the iconic lettered series, including Models A, B, D, G, M, and R, representing the backbone of John Deere production from the 1920s through the early 1950s. These machines are not just mechanically significant, they define the brand’s transition into scalable row crop mechanization.
The collection includes a mix of original, partially restored, and fully restored units. Importantly, the entire lineup has been stored indoors in a dry, enclosed environment, with regular engine operation maintained until roughly five years ago. From a technical standpoint, that kind of storage and periodic use significantly reduces long term degradation risks in engine internals and drivetrain components.
Mechanical condition and storage add real value
Across the board, the tractors are described as being in sound mechanical condition, with good tires and in many cases new rubber installed during restoration. For collectors and buyers, this detail matters more than cosmetic finish. Mechanical readiness reduces immediate recommissioning costs and lowers uncertainty around internal wear, especially on early two cylinder engines where parts sourcing can be more complex.
Another important signal is that the machines were driven into storage rather than parked after failure. That typically indicates functional condition at the time of storage, which is often a key differentiator in vintage auctions.
Wide lot range expands appeal beyond tractors
While the core of the sale is clearly tractor focused, the catalog extends into parts, tools, and memorabilia. This includes magneto components, carburetors, generators, wheel assemblies, and even dealership signage. For restorers, these lots can be just as valuable as complete machines, especially when dealing with period correct rebuilds.
The auction also features several non John Deere entries from additional vendors, including vintage machines from Caterpillar and Massey Ferguson, adding further diversity to the offering.
Most interesting lots from a technical and collector perspective
1926 Model D stands out as historical anchor
The 1926 Model D is arguably the most important piece in the lineup. As one of the earliest long running John Deere tractor models, it represents the brand’s first major step into gasoline powered farming. Early examples with correct configurations and matching components are increasingly difficult to source, making this a cornerstone collector item.
1947 Model B and 1951 Model A offer balanced value
The Model B and Model A tractors from the late 1940s and early 1950s are likely to attract strong bidding due to their balance between usability and collectibility. These machines are practical enough for demonstration use while still carrying strong historical relevance.
Styled and unstyled Model D comparison adds depth
The presence of both styled and unstyled Model D units creates an interesting technical contrast. Styled tractors introduced improved ergonomics and visual identity, while unstyled versions retain a more industrial design language. Having both in one sale allows buyers to compare engineering evolution within the same model line.
John Deere Model R introduces diesel relevance
The 1953 Model R is significant as John Deere’s first production diesel tractor. From a technical standpoint, this marks a major shift in fuel efficiency and torque characteristics, making it particularly attractive for collectors interested in drivetrain evolution.
Caterpillar Thirty and RD6 expand beyond agriculture
The inclusion of a 1927 Caterpillar Thirty and a 1936 RD6 crawler adds a construction and track type dimension to the sale. These machines appeal to a different segment of collectors focused on early earthmoving technology and tracked propulsion systems.
