Where to find the model number on the mower

Craftsman model 917388834 is identified by its model number, not a date code; the year is not encoded in “917388834.” For the most accurate age and specifications, we use the model’s documentation and the engine identification details shown in the 917388834 owner's manual.

What the model number tells you (and what it does not)

The 917388834 number is the mower’s model identifier used to match the correct parts (blade, cable, handle hardware) and the correct manual. It does not follow a month-day-year format.

Common places people look for a “year” on a walk-behind mower:

• The engine model/type/code stamped on the engine shroud
• A product label on the deck or rear housing
• The manual printing/revision information
• The purchase date on your receipt

How to determine the mower’s approximate year

We recommend using the engine’s identification because it often includes a manufacturer date code.

1. Locate the engine information on your mower (typically on the blower housing).
2. Write down the engine model number and any code/date string.
3. Compare it to the engine information listed in the manual.

From the documentation for this mower, the engine is listed as:

Item	What we see for model 917388834
Mower type	Rotary lawn mower, 21-in rear discharge
Engine family	Briggs & Stratton 4-cycle
Engine model number	10L902-0488-E1

Why it matters

Getting the year right helps when you are matching OEM replacement parts and service procedures, especially for wear items like the blade and blade adapter.

If you are replacing cutting parts, match by model and part ID, for example:

• Husqvarna lawn mower 21-in deck 3-in-1 blade 532189028
• Lawn mower blade adapter 581547901
• Walk-behind lawn mower engine cable 532176556
