Thorough, accurate research. Certified and officially notarized by the Two-Cylinder Club. Presented on brilliant white, acid-free archival stock, shipped flat and fully suitable for framing.

Production information on most models of John Deere Two-Cylinder Tractors is available at $45 for each research. The information will be supplied on a personalized document especially created for this purpose.

Documents will be sent flat (non-folded). The charge for shipping is $12.00 per order which includes Priority Mailing, a reinforced package (includes air mail to Canada and all other locations), and delivery confirmation. Several documents can be mailed together in the same package at no additional mailing charge. Processing time is between six to eight weeks.

Production information is available for nearly all vintage John Deere Tractors, from the Waterloo Boy through Generation II. There are some exceptions, as no production information is known to exist for Model “L” Tractors prior to serial number 625000, or for the Model “62” and Model “Y” Tractors. There also are no records for Model “M” Tractors prior to serial number 52542, for Model “W” Power Units after serial number 5289, or for Model “840” Tractors after serial number 8400848. And, regarding New Generation Tractors, the entire alpha-numeric serial number (not just the numerical sequence) must be provided to assure complete and accurate research.

We believe it is important that the requester tell us as much about their tractor(s) as possible. Some of the later models do not have full descriptions in the records. For example, all 4620s are shown in the Serial Number Register as row-crop tractors, even though some were built as Standards. Without full information from the owner, it will show on the Official Document as a row-crop tractor. There are many such examples throughout the John Deere line, but especially so with some tractors built after 1960. Please take the time to fully describe your tractor when requesting research.

The production information available varies considerably from model to model, and sometimes from tractor to tractor within a given model. For example, shipping destinations are not available for any tractors built at the Dubuque Tractor Works, specific shipping destinations (other than the Branch House Territory) are sometimes not available for Waterloo-built tractors, optional equipment is typically not available for most Waterloo tractors built in the 1950s (and is inconsistently available for earlier tractors), and a “build” date is not necessarily the date a tractor was built as much as it is the date that the tractor was entered into inventory.

Serial Number Research may be requested by mail, E-mail, website order, or phone at the addresses and phone numbers shown below. Please remember, payment information (including shipping) must accompany each serial number order.

Let’s Go Through This One More Time…

  • This is not a push-button process, nor does it fall into the category of “instant gratification.”
  • TRACTOR SERIAL NUMBER RESEARCHES are just that. The program is designed to research tractors that have serial numbers. Component numbers (ie: engine serial numbers) CANNOT be used to “back-into” TRACTOR SERIAL NUMBERS. It does not matter how many times “I heard” or “but you used to…” this is reiterated or rephrased during the conversation, the answer is still the same. “Can’t do it.” Or, if you prefer, “Ain’t gonna happen.”• Research information is only provided on a document. It provides a clear and logical paper trail, without the chance for any misinterpretations or misunderstandings which could occur during a verbal conversation.
  • An announcement which appeared in the May–June 2009 issue stated that “The Serial Number Search Program was based on being able to produce the great majority of the documents through the use of electronic files, but the gradually shifting tide of interest in specific tractor models has instead moved away from the previous pattern. This has resulted in the need for regular trips to the Deere & Company Archives to gently page through the original Serial Number Registers for tractor production information. Also, the parameter of four to six weeks for research requiring access to the Serial Number Registers, will now be four to eight weeks in an effort to reduce the number of trips to the Archives.”

Since that announcement was published in 2009, the number of Serial Number Research Requests requiring the trip to Moline have more than quadrupled per two-month interim, and the number of people available to research, understand, and decipher the information has dropped from four to one. Obviously, this also plays a major role in processing time. The new time frame is between eight weeks (minimum) to up to 18 weeks (or possibly more) from the time the order is placed. Emailing or calling repeatedly will not expedite the process; in fact, it slows it down. If you are not willing to be patient when placing your order for researches, then this program is not for you.
