What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label by itself is not a single model number; Craftsman used 6.75 HP on many different walk-behind mowers. The model number is on the mower’s ID tag (often starting with 917), and that exact number is what we use to match the correct parts.
Where to find the model number on a Craftsman mower
Look for a sticker or metal tag in one of these common spots:
- Rear of the deck near the bagger opening
- Under the seat area on self-propelled models with a rear cover
- On the side of the deck near a rear wheel
- On the handle support bracket
- Near the engine mounting area (deck surface)
If you see 917253721, that is a Craftsman riding tractor model (front-engine lawn tractor), not a 6.75 HP walk-behind mower.
What the model number usually looks like
Most Craftsman mower model numbers follow a pattern like:
- 917.XXXXXX (sometimes printed without the dot as 917XXXXXX)
Quick ID table
| What you see | What it usually means | What to do next |
|---|---|---|
| “6.75” or “6.75 HP” | Engine power label, not a model number | Find the ID tag and record the full model number |
| “917…” | Craftsman model prefix | Use the full 917 number to look up parts |
| Engine brand/model (Briggs, Kohler, etc.) | Engine identification | Use it only for engine-specific parts (filters, carb, ignition) |
Why it matters
Using the wrong model number can lead to ordering the wrong blade, belt, drive cable, or carburetor parts. The deck size, drive system, and engine family can vary even when the mower is labeled “6.75.”

What year is my Craftsman mower serial number lookup?
On a Craftsman riding mower like model 917253721, the model number does not tell the year; you typically date the tractor by decoding the serial number on the ID tag. Many Craftsman/Husqvarna-built tractors use a date-coded serial where the digits represent month, day, and year.
Where to find the serial number on model 917253721
Look for a product ID label (ID tag) on the tractor. Common locations include:
- Under the seat pan or on the seat deck
- On the frame rail near the engine
- Near the rear fender area
- Under the hood on the chassis
If the label is dirty or faded, wipe it clean and use a flashlight; one wrong digit changes the date.
How the serial number date code is commonly read
A very common format is MMDDYY (month, day, year) within the serial number.
| Example digits | Meaning | Example result |
|---|---|---|
| 07 | Month | July |
| 28 | Day | 28th |
| 11 | Year | 2011 |
So a serial number that begins with (or contains) 072811 is typically read as July 28, 2011.
Quick checks to avoid a wrong year
Before you order parts or record the year, we recommend these quick checks:
- Confirm you are reading the serial number, not the model number (model is 917253721)
- Write the serial number down exactly; include any leading zeros
- If the serial includes more digits, look for a 6-digit date block (often MMDDYY)
- Compare the decoded year to the tractor’s features (engine type, dash style, hood style)
- Use the model number 917253721 to match parts by diagram, not by guessed year
Why it matters
The “year” is helpful for general reference, but parts fit is driven by the exact model and component design, not the calendar year. For model 917253721, using the correct parts list helps you match items like the starting circuit and steering hardware accurately.
If you are troubleshooting a no-crank or intermittent start while you are doing the lookup, common related parts on this model include the starter switch 532365402 and solenoid 532146154.

What is the average lifespan of 917253721?
A Craftsman front-engine lawn tractor like model 917253721 typically lasts 10 to 15 years with normal residential use and consistent maintenance. Lifespan is driven most by engine care, drive system condition, and how well the deck and steering components are kept adjusted and lubricated.
What most affects lifespan
- Maintenance frequency: oil changes, air filter, spark plug, fuel system care
- Operating conditions: dusty mowing, steep hills, heavy towing, wet storage
- Drive system wear: belts, idlers, pulleys, and varidrive components
- Steering and axle wear: bearings, seals, and wheel hardware
- Electrical reliability: battery cables, switches, and starting circuit parts
Quick maintenance targets (typical)
| Item | Typical interval | Why it matters |
|---|---|---|
| Engine oil change | Every 25 to 50 hours or each season | Prevents internal engine wear |
| Air filter service | Every season (more in dust) | Protects engine from dirt ingestion |
| Fuel system check | Each season | Prevents hard starting and stalling |
| Grease/lube points | Every season | Reduces steering and chassis wear |
Parts that commonly extend service life
If you are refreshing wear items on 917253721, these are common “keep it going” parts categories:
- Starting circuit components such as the solenoid 532146154
- Fuel delivery items such as the fuel line 587044854
- Steering/axle wear items such as the wizard lawn tractor axle flange bearing 532009040
- Drive belt routing wear points such as idlers (match by diagram and location)
Why it matters
A tractor that is maintained on schedule usually fails gradually (hard starting, slipping drive, uneven cut) instead of suddenly. Replacing small wear parts early often prevents bigger repairs and downtime during mowing season.
