What model number is the Craftsman 917374382?
The model number is 917.374382; it’s printed on the Craftsman rotary lawn mower’s model tag and shown on the cover of the 917374382 owner's manual. This identifies the exact walk-behind mower version for ordering parts and matching specifications.
Where to find the model number on the mower
Look for the model tag in common ID locations used on Craftsman walk-behind mowers:
- On the rear of the mower deck near the discharge opening
- On the top of the deck near the engine mounting area
- Near the handle mounting brackets
- On a label near the rear door or rear skirt area
Why the model number matters
Using 917.374382 ensures we match the correct parts list and diagrams for your mower (for example, the 21-inch blade and handle components). It also helps avoid ordering a similar-looking part that will not fit.
Quick ID check: model number vs. other numbers
| What you see | What it means | Use it for |
|---|---|---|
| 917.374382 | Mower model number | Parts lookup, diagrams, manual match |
| Engine model (example: XT675-3105) | Kohler engine model | Engine-specific parts and tune-up items |
| Part number / part ID | Individual replacement part identifier | Ordering the exact replacement part |
Helpful tip when ordering parts
When you’re replacing wear items, match the part to the mower model first, then confirm the part details in the diagrams.
- Blade: confirm deck size and blade style (mulching vs. standard)
- Hardware: match the exact fastener type and size
- Handle controls: confirm cable routing and control bar style
If you’re replacing the blade on this model, the listed 21-inch blade is lawn mower 21-in deck mulching blade 532406706.

What year is Craftsman Model 917374382?
The Craftsman model 917374382 is identified in the documentation as a rotary lawn mower model number, but the year of manufacture is not encoded in the model number itself. To determine the year, we use the mower’s product ID or date code on the unit and confirm it against the information in the 917374382 owner's manual.
Where to find the date information on the mower
On Craftsman walk-behind mowers like model 917374382, the build date is typically shown on a label or stamped code on the mower, not in the model number.
Check these common locations:
- The rear of the deck near the discharge opening or rear door
- Under the engine shroud area (visible without disassembling anything)
- Near the handle mounting brackets on the deck
- On a product label that also lists the model and serial information
How to decode what you find
Once you locate the code, match it to the format used on your label.
| What you find | What it usually means | What to do next |
|---|---|---|
| Model number (917374382) | Identifies the mower design and parts list | Use it to order parts and reference specs |
| Serial/date code | Identifies production timing | Decode the date or use it to confirm the year |
| Engine model (XT675-3105) | Identifies the Kohler engine version | Use it for engine-specific parts and service |
Why the year matters
The production year helps ensure you get the correct replacement parts when there are mid-series changes (especially for deck hardware, control cables, and handle components). For example, the correct blade and related fasteners for this mower include the lawn mower 21-in deck mulching blade 532406706 and the matching mounting hardware listed in the parts breakdown.
Quick parts cross-check (helps confirm you have the right model)
If your mower matches these common components shown for 917374382, you are on the right track:
- 21-inch blade setup (blade and adapter)
- Rear door and discharge components
- Engine zone control cable and control bar

What is the average lifespan of 917374382?
A Craftsman walk-behind mower like model 917374382 typically lasts 8 to 12 years with normal residential use and on-time maintenance. Following the oil, air filter, and blade service intervals in the 917374382 owner's manual is what most directly determines how long it runs reliably.
What affects lifespan the most
- Oil changes: change oil about every 25 hours of operation or at least once per year.
- Air filter care: clean or replace regularly; replace about every 100 hours or each season.
- Blade condition: a sharp, balanced blade reduces engine load and improves cut quality.
- Storage habits: off-season fuel handling and cleaning under the deck prevent corrosion and starting issues.
- Operating conditions: dusty, sandy, or heavy-load mowing shortens service life without extra maintenance.
Maintenance intervals at a glance (from the manual)
| Item | Typical interval | Why it matters |
|---|---|---|
| Check engine oil level | Before use and after 5 hours continuous use | Prevents low-oil wear and overheating |
| Change engine oil | Every 25 hours or yearly | Extends engine life |
| Replace air filter cartridge | Every 100 hours or each season | Protects engine from dirt ingestion |
| Check/sharpen/replace blade | As needed (more often in sandy soil) | Reduces vibration and engine strain |
When replacement is usually the better value
- Engine starts but surges, smokes, or lacks power even after tune-up maintenance
- Deck rust-through or cracking near mounting points
- Persistent vibration after blade and adapter inspection
- Drive or control components are worn and multiple repairs are stacking up
Why it matters
Most “mower lifespan” is really engine and deck lifespan. Keeping oil clean, airflow unrestricted, and the cutting system tight and balanced helps your Kohler-powered 21-inch mower avoid the wear that ends its service life early.
