Craftsman 917388850 rotary lawn mower Parts

On Craftsman rotary lawn mower model 917388850, the serial number is primarily used to identify your exact unit for parts and service; we match it with the model number from the ID decal on the rear of the mower housing. For serial-number format details, use the 917388850 owner's manual.

Where to find the model and serial number

You will find the identification decal on the rear of the lawn mower housing.

• Look on the back of the deck (rear of the mower housing)
• Wipe off grass and dirt so the decal is readable
• Record the model number (917388850) and the serial number
• Write down the date of purchase as well (helpful for warranty and maintenance records)

How to interpret the serial number

Craftsman mower serial numbers are not always a simple, universal “MMDDYY” code across every mower and production run. The most reliable way to interpret your specific serial number is to use the model’s documentation and parts diagrams.

What we recommend doing

• Use the serial number to confirm the correct parts list for your exact mower
• Compare your mower’s configuration to the illustrated parts breakdown in the manual
• If you are trying to date the mower, use the manual and the ID decal information together

Why the serial number matters

The serial number helps prevent ordering the wrong part when there are mid-year changes (for example, handle hardware, wheel hardware, or control-cable routing).

What you’re doing	What to use	Why it helps
Ordering parts	Model + serial number	Matches the correct parts diagram
Maintenance tracking	Serial number + purchase date	Keeps service history organized
Troubleshooting fit issues	Serial number	Helps identify running changes
