What year is my Craftsman mower serial number lookup?
On a Craftsman riding mower like model 917258561, the serial number (not the model number) often includes a date code that can be read as month, day, year. Once you find that date code on the ID tag, the last two digits typically indicate the build year.
Where to find the serial number and date code
Look for the product ID label in one of these common spots:
- Under the seat pan (lift the seat)
- On the frame rail near the engine
- Near the rear fender or hitch plate
- Under the hood on the chassis
How to read the date code (common Craftsman format)
Many Craftsman-built lawn tractors use a 6-digit date code that reads like this:
- First 2 digits = month (01 to 12)
- Next 2 digits = day (01 to 31)
- Last 2 digits = year (00 to 99)
Example
If the date code is 072811, that reads as:
- 07 = July
- 28 = 28th
- 11 = 2011
Quick check table
Use this to sanity-check what you are seeing on the tag.
| Date code | Interprets as | Year |
|---|---|---|
| 031205 | March 12, 2005 | 2005 |
| 072811 | July 28, 2011 | 2011 |
| 110919 | November 9, 2019 | 2019 |
Why it matters
Knowing the build year helps us match the correct parts and diagrams for your Craftsman tractor, especially for deck parts, belts, and electrical items that can change across production runs.
Parts that commonly depend on the exact build
- Mower deck blade and mandrel style
- Blade drive belt length and routing
- Starter solenoid wiring layout
- Steering and front axle hardware
If you are already shopping parts for this tractor, match by model first, then confirm by the part listing, such as the solenoid 532146154 or the lawn tractor drive belt 532144200.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman 917258561 front-engine lawn tractor is worth it when the tractor’s deck, steering, and drive components are solid and the total engine-swap cost stays well below the cost of replacing the whole tractor. If the tractor has multiple worn systems, replacement is the better value.
Quick decision checklist
We use these factors to decide whether an engine replacement makes sense:
- Deck condition: no major rust-through, cracks, or bent structure (a damaged deck can cost more than it is worth to fix)
- Drive system health: transaxle drives smoothly, no slipping or loud grinding
- Electrical reliability: wiring is intact and starting issues are not chronic (a bad starter circuit can mimic engine failure)
- Parts availability: common wear parts are still easy to get for your model
- Total cost: engine + labor + tune-up parts is clearly less than replacing the tractor
Cost rule of thumb (what we recommend)
If the engine replacement (parts plus labor) is under about 50% of the cost of a comparable replacement tractor, the swap is usually a good investment. If it is near or above 50%, replacement typically makes more sense.
| Situation | Best choice | Why |
|---|---|---|
| Deck and drivetrain are strong | Replace engine | You keep a known-good chassis and controls |
| Deck is rusted/cracked or spindles are worn | Replace tractor | You will chase cut-quality and vibration problems |
| Transaxle is weak/noisy | Replace tractor | A transaxle repair plus engine cost stacks up fast |
Parts that often get addressed during an engine swap
Even with a new engine, these items commonly affect performance and cut quality on a riding mower:
- Blade drive belt if it is glazed, stretched, or slipping: lawn tractor drive belt 532144200
- Mandrel/spindle components if you have wobble or vibration: husqvarna lawn tractor mandrel assembly 532130794
- Starter circuit parts if you have clicking or intermittent cranking: solenoid 532146154
Why it matters
An engine swap can restore reliability, starting, and power, but it does not fix underlying deck vibration, belt slip, or drivetrain wear. Confirming the deck, mandrels, and transaxle are in good shape prevents spending engine money on a tractor that still will not cut or drive correctly.

What model number is a Craftsman 6.75 lawn mower?
Craftsman “6.75” is an engine power label used on many different walk-behind mowers, so it does not identify one single model number. To get the exact model number, check the mower’s model tag (usually a sticker or plate on the rear deck, under the seat area on some units, or near the handle mounts) and match it to the format used on Craftsman equipment.
Where to find the model number on a Craftsman mower
Look for a model/serial label and write down the full model number exactly as shown.
- Rear of the mower deck (most common on walk-behind mowers)
- Under the engine shroud area (near the recoil starter housing)
- Near the handle brackets or height adjuster area
- On the frame rail (some designs)
- Sometimes inside the battery compartment (electric start models)
What the model number usually looks like
Most Craftsman walk-behind mower model numbers are a 9-digit number starting with 917 (example format: 917.XXXXXX or 917XXXXXX). Your label may also include a separate serial number.
| What you see | What it means | What to record |
|---|---|---|
| 6.75 (on engine cover) | Engine rating/series | Not enough by itself |
| Model number (often starts with 917) | Identifies the mower | Record the full model |
| Serial number | Production identifier | Record if ordering parts |
Why it matters
The correct model number is what ensures you get the right parts and specs (blade, drive belt, wheels, and deck components). “6.75” alone can match many different Craftsman mower builds.
If you are trying to match parts
If your mower is actually a Craftsman riding tractor model 917258561 (the model this page covers), you can use the parts list here for common wear items such as the husqvarna lawn tractor mulching blade, 21-in 532134149 or the lawn tractor drive belt 532144200.

What engine does Craftsman riding mower use?
Craftsman riding mowers use a range of engines depending on the exact model and build; for Craftsman model 917258561, the engine is identified by the engine model and specification numbers on the engine label (not by the tractor model number alone). Once you match those numbers, you can choose the correct tune-up and starting-system parts.
How to identify the engine on model 917258561
Look for the engine ID tag or sticker on the engine itself (not the hood or frame). Common locations include the blower housing, valve cover area, or near the starter.
- Write down the engine brand (often Briggs & Stratton, Kohler, or Tecumseh on tractors of this era)
- Record the engine model and spec numbers exactly as shown
- If present, record the type and code numbers (these help pinpoint the exact build)
- Use those numbers to confirm the correct carburetor, air filter, spark plug, and fuel parts
- If the label is missing, use the tractor parts diagrams to identify related components (starter, wiring, pulleys) and narrow it down
Parts that commonly relate to engine starting and operation
Even before you know the exact engine model, these parts on the tractor often affect starting and drive engagement:
- Solenoid 532146154 (starter solenoid; common cause of a click-no-crank symptom)
- Battery cables and grounds (loose or corroded connections)
- Safety interlock switches (brake, PTO, seat)
- Fuel quality and air filter condition (stale fuel and restricted airflow cause hard starting)
Quick symptom guide
| What you notice | Most likely area to check first | What to do next |
|---|---|---|
| Clicks but won’t crank | Solenoid, battery, cables | Test battery voltage; inspect connections; consider replacing solenoid |
| Cranks but won’t start | Fuel, spark, air | Check fresh fuel, spark plug, air filter |
| Starts then dies when releasing brake | Safety interlock circuit | Inspect brake switch and wiring |
Why it matters
The tractor model number 917258561 tells us which chassis and deck parts fit, but the engine tag tells us which ignition, fuel, and tune-up parts fit. Matching the engine model and spec prevents ordering the wrong carburetor or ignition components.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917258561, a full engine replacement typically costs about $600 to $2,500 installed. The total depends on the engine price, whether the crankshaft matches your existing pulleys and PTO setup, and labor time (often 4 to 8 hours).
What drives the total cost
- Engine cost: Most of the bill; replacement engines vary widely by horsepower and shaft specs.
- Labor: Shops commonly charge several hours for removal, swap, and testing.
- Extra parts: Belts, pulleys, wiring repairs, and hardware often get replaced during the job.
- Deck and drive condition: If the deck spindles or drive system are worn, you may choose to repair those at the same time.
- Pickup and delivery: Some services add transport fees.
Typical price ranges (installed)
| Scenario | What’s included | Typical total |
|---|---|---|
| Budget swap | Basic engine replacement, minimal extras | $600 to $1,200 |
| Most common | Engine plus a few wear items and adjustments | $1,200 to $2,000 |
| Higher-end | Engine plus multiple related repairs | $2,000 to $2,500 |
Parts that commonly get addressed during an engine swap
Even though the engine itself is separate, we often see these related items replaced or inspected on riding mowers:
- Deck belt condition and routing (example: lawn tractor drive belt 532144200)
- Starter circuit components (example: solenoid 532146154)
- Deck spindle and mandrel wear (example: husqvarna lawn tractor mandrel assembly 532130794)
- Blade and spindle hardware torque and condition
- Battery cables and grounds (clean and tighten)
Why it matters
An engine replacement only pays off if the rest of the tractor is solid. If the transaxle, deck, or steering has major wear, putting a new engine on can raise the total investment beyond the mower’s practical value.
