On many Craftsman riding mowers, the build date is encoded in the serial number as MMDDYY (month, day, year). For your Craftsman model 917258543, we recommend confirming the exact serial-number format and tag location in the owner's manual before decoding.

How to decode the serial number (common Craftsman format)

If your serial number uses the common 6-digit date code, read it like this:

• First 2 digits: month (01 to 12)
• Next 2 digits: day (01 to 31)
• Last 2 digits: year (00 to 99)
• Example: 072811 = July 28, 2011
• If your tag includes extra letters or a longer string, the date code is often embedded within it

Where to find the serial number tag

Serial number labels are commonly found in one of these places on a front-engine lawn tractor:

• Under the seat pan or on the seat support
• On the frame near the rear wheels
• Under the hood near the engine compartment
• On the fender pan near the operator position

Quick checks if the date code does not seem to fit

Use these checks before you rely on the decoded year:

• Make sure you are reading the serial number, not an engine model number
• Look for a 6-digit block that can be read as a real calendar date
• If the “month” digits are higher than 12, you are likely not looking at a date code
• Compare the decoded year to the tractor’s parts diagrams and decals listed for model 917258543

Why it matters

Knowing the correct year helps us match the right mower deck and drive components for your Craftsman 917258543, such as the lawn tractor drive belt 532144200 or the husqvarna lawn tractor mandrel assembly 532130794, so the belt routing, pulley sizes, and mounting points line up correctly.
