Please see the documents attached to find the year of manufacture on your Countax or Westwood* unit and also how to translate the codes to get the information on your tractor. 


Finding the serial number is the same for Countax and Westwood* after 2001.


*Westwood machines changed how the serial number was shown in 2001 to the same as the Countax. We don't have the records for any westwood machines pre 2001 but the units should have the Date Of Manufacture on them.



Attached are 2 different types of serial number plaques that are found on the units.
