Here's why:
* Serial Number Format: The format of the serial number you provided is not the typical format for John Deere riding mowers. The "M00" prefix is not standard, and the following number appears to be excessively long for a John Deere serial number.
* Missing Information: John Deere serial numbers usually include a year code or a model-specific identifier that would help pinpoint the manufacturing date.
To determine the year of your STX38, you'll need to try these steps:
1. Check for additional information: Look on the ID tag for any other markings, such as a model number, engine information, or a date code.
2. Contact John Deere: Reach out to John Deere customer support (either online or by phone) with the serial number you have. They may be able to help you determine the year of manufacture.
3. Consult a John Deere dealer: Visit your local John Deere dealer and show them the ID tag. They have access to databases and resources that can help identify the age of your mower.
Good luck!
