Kubota Serial & Model Number Guide
Every Kubota engine carries a model/serial label. Here is where to find it, what each part of the number means, and how to use it for parts, service and age.
What the number means
Worked example — Model D1105 · Serial (7-digit from Jun 2012):
| Part | Meaning | Detail |
|---|---|---|
D1105 | Engine model | Kubota engine model designation (series + displacement class). |
1st char | Year of manufacture | First character of the serial encodes the build YEAR (rolling code). |
2nd char | Month of manufacture | Second character encodes the build MONTH. |
rest | Sequence | Production sequence (7-digit from Jun 2012; 6-digit before). |
Using the serial number
Record BOTH the engine model and the serial from the block. Kubota is the one case here where the serial itself gives the age: on June-2012-and-later 7-digit serials the first character is the year of manufacture and the second is the month. (Don't use the model on the EPA label — use the model stamped on the block.)
Common Kubota maintenance parts
The service parts Kubota's own documents list across more than one engine model. Confirm the number for your unit on its model page or data plate before ordering.
