How old is my mower by serial number?
On Craftsman model 917376480, the serial number is on a decal on the rear of the mower housing; once you have that serial number (and your purchase date if you know it), you can determine the mower’s age by matching it to Craftsman’s date-code format. The location details are shown in the 917376480 owner's manual.
Where to find the model and serial number
Look for a decal on the rear of the lawn mower housing (behind the deck area). On that decal you should see:
- Model number: 917376480
- Serial number (unique to your mower)
- A place to record the date of purchase (often written in by the owner)
How to estimate the mower’s age from the serial number
Once you’ve copied the serial number exactly, use these practical checks to narrow down the build timeframe:
- Compare the serial format to Craftsman/Husqvarna-built mower serial patterns (often include a date code).
- Check for a recorded purchase date in your paperwork; the manual provides a spot to record it.
- Use the engine model and type (this mower uses a Briggs & Stratton 675 Series engine) as a cross-check when looking up engine date codes.
- Confirm the decal is original; replacement housings or decals can mislead age estimates.
Quick checklist (what to write down)
- Model number: 917376480
- Serial number: (copy exactly, including any letters)
- Date of purchase: (month/year is enough)
- Engine family/model info (from the engine label)
Why it matters
Knowing the mower’s age helps us choose the right replacement parts (like a drive control cable, wheel, or blade), confirm maintenance intervals, and avoid ordering hardware that changed across production runs.
Common age-related maintenance to plan for
If the mower is several seasons old, these are the most common wear items to inspect:
| Item | What to look for | Typical action |
|---|---|---|
| Blade | Nicks, rounding, vibration | Sharpen or replace |
| Drive system | Slipping or no self-propel | Inspect cable, pulleys, wheels |
| Wheels | Wobble, poor traction | Replace wheel components |
| Fuel system | Hard starting after storage | Fresh fuel, tune-up |
For blade service steps and safe handling, follow the how to sharpen a lawn mower blade guide.

How to read a Craftsman mower serial number?
On Craftsman walk-behind mower model 917376480, the serial number is primarily used to identify your exact production run for parts and service; you’ll find it on a decal on the rear of the mower housing. Use the format shown in your 917376480 owner’s manual to record the serial number and purchase date.
Where to find the serial number on model 917376480
Look for a decal (label) on the rear of the lawn mower housing.
- Tip the mower only as directed in the manual (to avoid oil or fuel issues)
- Wipe grass and dirt off the rear housing so the decal is readable
- Write down both the model number (917376480) and the serial number
- Record the date of purchase as well (helpful for maintenance history)
How to interpret the serial number
Craftsman serial-number formats vary by product line and manufacturing era. Many owners see date-style codes (month, day, year) in some Craftsman serials, but the most reliable approach is to match your serial to the format and examples in the documentation for your exact mower.
Quick guide (what to do with the number)
| What you need | Where it’s used | Why it helps |
|---|---|---|
| Model number: 917376480 | Parts lookup | Ensures diagrams match your mower |
| Serial number (from decal) | Service identification | Confirms the exact build/version |
| Date of purchase | Maintenance and records | Helps track warranty and upkeep |
Why it matters
The serial number helps us narrow down the correct parts and configurations when there are mid-year changes, especially for wear items like wheels, cables, and blade hardware.

What are the common problems with Craftsman lawn mowers?
Common problems on the Craftsman 917376480 walk-behind mower include hard starting, rough running, poor cut quality, excessive vibration, a starter rope that’s hard to pull, and self-propel drive issues (hard to push or loss of drive). Our 917376480 owner's manual troubleshooting chart points to blade condition, wheel height, grass buildup, and drive-wheel debris as frequent causes.
Most common symptoms and what usually causes them
- Won’t start or runs poorly: stale fuel, dirty air filter, fouled spark plug, or fuel system restriction
- Poor cut or uneven cut: worn or bent blade, uneven wheel height settings, grass buildup under the deck
- Excessive vibration: loose or damaged blade, or a bent crankshaft after striking an object
- Starter rope hard to pull: blade dragging in heavy grass, brake engaged when the control bar is released, or internal damage after impact
- Hard to push or self-propel slows: drive wheels packed with grass and debris, belt wear, or belt off the pulley
Quick checks we recommend (fast, no special tools)
- Shut the engine off and disconnect the spark plug wire.
- Tip the mower safely (air filter and carburetor side up) and clean the underside of the deck.
- Confirm all wheels are set to the same cutting height.
- Inspect the blade for bends, cracks, or looseness; replace if damaged.
- If it’s self-propelled and won’t move well, clean the front drive wheel area; debris in the pinion and gear teeth commonly causes drag.
Drive-wheel cleaning parts you may need
If the drive wheel area is worn or missing pieces after cleaning, these model-matched parts are commonly involved:
| Area | What it affects | Example part for this model |
|---|---|---|
| Wheel and traction | Rolling, height, drive engagement | Lawn mower wheel 532433121 |
| Wheel gear area | Self-propel movement | Pinion.14.te 532403849 |
| Wheel protection | Keeps debris out of wheel area | Lawn mower wheel dust cover 581840401 |
Why it matters
Most “big” mower problems start as simple maintenance issues. Keeping the blade straight and sharp, the deck clean, and the drive wheels free of packed grass helps the 917376480 cut evenly, start easier, and maintain consistent self-propel speed.

What model number is a Craftsman 6.75 lawn mower?
For a Craftsman 6.75 (675 Series) walk-behind mower, the model number is printed on the mower’s model decal; for this Sears PartsDirect page, the mower is Craftsman model 917376480. You can confirm it on the rear of the mower housing and in the 917376480 owner's manual.
Where to find the model number on the mower
Look for the model and serial number decal in these common spots:
- Rear of the mower housing (most common on this Craftsman platform)
- Near the deck, behind the engine
- On the handle support area near the height adjusters
- In the battery/electric start area if equipped
What “6.75” usually means on Craftsman mowers
On many Craftsman walk-behind mowers, “6.75” refers to the engine family or series (often shown as 675 Series on the engine shroud), not the mower’s full model number.
- The engine may say 675 Series
- The mower uses a longer model number (example: 917376480)
- Parts lookup and diagrams require the mower model number, not just the engine label
Quick ID checklist (use this before ordering parts)
Match these identifiers to avoid ordering the wrong blade, cable, or wheel:
- Model number on the mower decal: 917376480
- Engine marking: 675 Series (Briggs & Stratton)
- Deck size: typically 22-inch on this model family
- Drive type: power-propelled (self-propelled)
Common “model number” vs “engine number” comparison
| What you see | What it identifies | What to use for parts |
|---|---|---|
| 675 Series / 6.75 | Engine series/family | Use for engine-specific tune-up items only |
| 917376480 | Complete mower model | Use for mower diagrams and most parts |
Why it matters
Craftsman mower parts like the drive control cable, wheels, and mulching blade are model-specific. Using the correct model number (917376480) helps ensure the right fit and avoids repeat repairs.
