What model number is the Craftsman 917370880?
The model number for this Craftsman walk-behind lawn mower is 917370880. You will use 917370880 to look up the correct Craftsman parts diagrams and to match replacement parts (like blades, wheels, and drive components) to your exact mower.
Where to find the model number on the mower
On Craftsman walk-behind mowers, the model number is typically printed on a product label. Check these common spots:
- Rear of the deck near the discharge opening
- Top of the deck near the engine mounting area
- Back of the mower housing near the height adjusters
- Handle support area (lower handle brackets)
Why the model number matters for parts fit
Many Craftsman mowers share similar-looking decks and handles, but parts can vary by production run. Using the exact model number helps us match the right part ID and hardware.
Common parts that often require an exact model match include:
- Blade and blade adapter
- Drive control cable and transmission parts
- Wheels, dust covers, and E-rings
- Discharge chute door springs and deflector parts

What year is Craftsman Model 917370880?
Craftsman model 917370880 is a model number, not a date code, so it does not directly tell the year. To find the year, we use the mower’s product ID (model tag) date code or the engine model and code stamped on the engine.
Where to find the build year on a Craftsman walk-behind mower
Look for a sticker or metal tag on the mower housing (often on the rear of the deck, near the height adjusters, or around the handle mount area). Common places to check:
- Rear of the deck near the discharge chute
- Top of the deck near the engine mounting area
- Back panel near the bagger opening
- Handle bracket area
- Under the grass bag flap (if equipped)
How to decode the date once you find it
Many Craftsman mowers use a 6-digit date code on the product ID tag in this format:
| Code position | Meaning | Example |
|---|---|---|
| 1-2 | Month (MM) | 07 = July |
| 3-4 | Day (DD) | 28 |
| 5-6 | Year (YY) | 11 = 2011 |
If your tag shows 072811, that decodes to July 28, 2011.
Quick cross-check: engine code (often easiest)
If the mower tag is missing or unreadable, the engine usually has its own identification code. Use that to confirm the approximate year.
- Find the engine model/type/code stamping (often on the valve cover, blower housing, or near the muffler)
- Match the code to the engine maker’s date format
- Use the engine date as a reliable build-year reference for the mower
Why it matters
Knowing the correct year helps us match the right Craftsman 917370880 walk-behind mower parts, especially wear items like the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 and discharge components.

Where is Craftsman's model number?
On a Craftsman walk-behind mower like model 917370880, the model number is printed on the mower’s product ID label (not on the engine). We use that mower model number to match the correct deck, handle, wheel, and drive parts.
Where to look on the mower
Check these common label locations on walk-behind mowers:
- On the rear of the deck near the discharge opening
- On the top of the deck behind the engine
- On the side of the deck near a rear wheel height adjuster
- On the handle bracket area where the handle bolts to the deck
- Under the grass bag door area (rear discharge models)
If the label is dirty or faded, wipe it with a damp rag first; grass dust and oil film can hide the numbers.
What number you need (mower vs. engine)
Many Craftsman mowers have two different ID plates. For most parts on this page, you want the mower model number.
| You’re replacing | Use this ID | Why |
|---|---|---|
| Blade, deck parts, wheels, bagging parts | Mower model number (example: 917370880) | Matches the chassis and cutting system |
| Engine tune-up parts (spark plug, carb parts) | Engine model/type/code | Matches the engine manufacturer’s parts list |
Why it matters
Using the correct mower model number prevents ordering parts that look similar but do not fit, such as the wrong blade center hole pattern or the wrong discharge hardware.
Parts that commonly require the mower model number
These are examples of chassis-related parts that match by mower model:
- Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
- Lawn mower clipping deflector 532426129
- Husqvarna lawn mower drive control cable 586033301
- Lawn mower transmission assembly 589599201

Is it cheaper to repair or replace a lawn mower?
For a Craftsman walk-behind mower like model 917370880, it’s cheaper to repair when the fix is routine and the total cost stays under about 50% of the price of a comparable new mower. Replace the mower when you’re facing major engine or self-propelled drive failures, repeated breakdowns, or multiple high-cost repairs.
Quick rule of thumb (repair vs. replace)
- Repair when the mower still starts reliably and needs wear items (blade, hardware, chute parts) or basic maintenance.
- Replace when the engine has low compression, the crankshaft is bent, or the drive system needs major work and the total bill climbs past half the cost of a new mower.
- Replace when you’re stacking repairs (example: transmission plus wheels plus handle components) in the same season.
Common repairs that usually make financial sense
These are typical “high value” repairs on a walk-behind mower because parts cost is modest and labor is straightforward:
- Replace a worn or bent blade such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
- Replace damaged discharge components like the lawn mower clipping deflector 532426129
- Fix loose blade mounting hardware (example: lawn & garden equipment nut 532409149)
- Replace a broken wheel or wheel hardware (dust cover, E-ring, washers)
- Tune-up items (fresh fuel, oil change, spark plug, air filter, carburetor cleaning)
When replacement is the better call
Major failures can quickly exceed the value of an older mower:
- Engine problems (hard starting plus smoking plus loss of power)
- Bent crankshaft after striking a stump or rock
- Self-propelled drive failure that requires a transmission replacement (example: lawn mower transmission assembly 589599201)
- Deck damage or severe rust-through that affects cut quality and safety
Cost comparison table
| Situation | Typical outcome | Best choice |
|---|---|---|
| Blade is dull/bent, mower runs well | Low parts cost, quick fix | Repair |
| Discharge chute/deflector is broken | Low to moderate parts cost | Repair |
| Transmission/drive system failure | High parts cost, more labor | Replace (often) |
| Multiple issues in one season | Costs add up fast | Replace |
Why it matters
A sharp blade and solid discharge setup protect your lawn’s health and reduce engine strain. On the other hand, sinking money into major drivetrain or engine work often costs more than the performance you get back.
