Craftsman model 917370950 is identified by its model number, not by a built-in “year” field. For this mower, the most reliable way to confirm the manufacturing date is to use the engine data plate and the date-code guidance in the 917370950 owner's manual.

How to find the year on your 917370950

On walk-behind mowers like the Craftsman 917370950, the mower model number tells us the configuration (deck, drive system, controls), while the engine identification is what typically provides a date code.

Check these common locations:

• Engine shroud or valve cover: sticker or stamped plate with model/type/code
• Recoil starter housing: label near the pull-start
• Mower deck or rear housing: product label with serial information (if present)
• Under the grass bag area: sometimes a label is placed near the rear door

What information to write down

Record these items before you search parts or service info:

• Mower model number: 917370950
• Engine brand and model (this mower uses a 190cc Honda engine, per the manual)
• Engine serial number and any date code
• Any serial number from the mower housing label

Quick guide: model number vs. date code

Item	What it tells you	Where to look
Mower model number (917370950)	Mower design and parts breakdown	Mower label, manual cover
Engine model/type/code	Engine build date and exact engine parts	Engine data plate
Mower serial (if present)	Production run tracking	Mower housing label

Why it matters

The correct year (and engine code) prevents wrong-part orders for tune-up items and drive components, and it helps match the right diagrams when you service the blade brake/clutch, drive control, or discharge system.
