I often read posts asking for a way to determine a Kubota tractor's age. There is no easy way to do that. Even the term "age" has more than one meaning where tractors are concerned. You can refer to websites like TractorData.com and perhaps get the years the Kubota model was produced, but that is about it. Following is some information that may be helpful if you want to pin down a particular tractor's dates.
A tractor is traditionally "aged" by the date the original dealer sold it.
Kubota tractor serial numbers have been sequential, showing the model number and a manufacturing sequence. They have not contained a code to determine age.
A polite e-mail to Kubota customer service giving them the model and serial number will usually get a reply with the tractor's year of manufacture, date of first sale and the original selling dealer's name.

A cooperative dealer can also get the information for you.
Reference to tractors for sale sites that give serial numbers and "claimed" age are useful in determined a tractor's "not older than and not newer than" age. This may be be all you want when looking at a used tractor.
Kubota engine serial numbers do have a code that indicates the date of production. Determining the engine's production date at least gives you a "built after date" for the tractor. Please refer to the attached information. The portion of the chart that covers tractors older than 2010 was omitted. The chart in its entirety can be obtained from Kubota, or by following the link below.
6-22-21 I recently learned that Kubota may be introducing an ISO compliant seventeen digit Equipment identification number. If that is the case, you will be able to decipher the VIN if you know Kubota's code. I do know that the first three digits will be the World Manufacture Code, and the last five will still be the manufacturing sequence. When Kubota institutes that, the vin will tell you the production date, but .........you will still need the code, and as I understand it, it will not be made public (dealers only). Here is the sequence.
1st, 2nd, & 3rd digit - World Manufacturer's code
4th digit - product line
5th digit - Series
6th digit - Horse Power
7th digit - Traction & Transmission
8th digit - Cab/ROPS
9th digit - check letter
10th digit - manufacture year (M = 2021)
11th digit - manufacturing factory
12th digit - manufacture month
13th-17th digits - Sequential number of manufacture
