What year is the Craftsman 917270630?
The Craftsman model 917.270630 is a specific riding lawn tractor model number, but the exact build year is determined by the serial number date code on your tractor. Use the date-code method in the owner's manual and the serial tag on the tractor to identify the year it was manufactured.
How to find the year on your tractor
Look for the model and serial number label (commonly under the seat, on the frame near the rear wheels, or under the hood). Then use the serial number to decode the manufacture date.
- Confirm the model number reads 917.270630 (sometimes shown as 917270630).
- Write down the serial number exactly as printed.
- Check for a date code embedded in the serial number.
- Compare what you find to the identification guidance in the owner's manual.
- If the label is damaged, clean it gently and use a flashlight to read stamped characters.
What the model number tells you (and what it does not)
The model number 917.270630 identifies the tractor family and configuration (Craftsman riding mower platform), but it does not reliably encode a single model year by itself. The serial number is what ties your unit to a specific production date.
Quick reference
| Identifier | What it identifies | Best use |
|---|---|---|
| Model number (917.270630) | Tractor design and parts breakdown | Ordering correct parts and diagrams |
| Serial number | Your exact unit’s production run | Determining manufacture date/year |
Why it matters
Knowing the correct year helps us match the right parts and diagrams for your Craftsman tractor, especially for wear items like the mower deck drive system and blades. For example, this model’s parts list includes items such as the lawn tractor drive belt 532144200 and the husqvarna lawn tractor mulching blade, 21-in 532134149, which must match your deck and configuration.
