FAQ
What year is my Cub Cadet by serial number?
You can determine the manufacturing year of your Cub Cadet by locating the serial number and comparing it with a serial number chart. For older models (especially those made between 1961–1981), the serial number range directly correlates to a specific year.
For newer models, Cub Cadet uses a date-coded system that may require decoding or a lookup via the official Cub Cadet website or dealer database.
How to read a Cub Cadet serial number?
A Cub Cadet serial number is usually a long numeric or alphanumeric code. For pre-1981 tractors, the numbers increase chronologically and are matched to a known year range. Newer models often use a format where specific digits represent the manufacturing date (e.g., YYMMDD).
