What engine does Craftsman riding mower use?
The Craftsman riding mower model 917256541 uses a single-cylinder gasoline engine, but the exact engine brand and horsepower rating depend on the specific engine configuration listed for your tractor. We recommend confirming the engine identification details in the 917256541 owner's manual before ordering engine parts.
How to identify the exact engine on model 917256541
Use these quick checks to match the correct engine family and service parts:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (or spec number)
- Compare that information to the engine repair parts section in the manual
- Match tune-up items by engine ID, not just by tractor model
- If you are replacing a major component, verify mounting pattern and crankshaft details first
Common engine-related parts you may need

Quick guide: tractor model vs. engine model
| What you have | What it tells you | What to use for parts matching |
|---|---|---|
| Tractor model 917256541 | Chassis, deck, drive system, and overall configuration | Use for belts, blades, deck, steering, transaxle |
| Engine model/spec (from engine label) | Exact engine build and service parts | Use for filters, ignition parts, carburetor parts, internal engine parts |
Why it matters
Craftsman tractors in this series were built with different engine variants over time. Using the engine’s model and spec information prevents ordering the wrong oil filter, ignition parts, or engine repair components.

What year is Craftsman Model 917256541?
Craftsman model 917256541 is a model number, not a date code; it does not directly tell you the year. To identify the year, use the serial number on the plate under the seat and match it using the date/serial information in the owner's manual.
Where to find the date information
On the Craftsman 917256541 tractor, we use the identification plate under the seat.
- Lift the seat and locate the model/serial plate
- Record the serial number exactly as shown
- Record the date of purchase if you still have it
- Use the manual’s identification section to confirm what the serial number format indicates
- Keep the information with your maintenance records for future parts lookups
Why the model number alone is not enough
The owner’s manual shows MODEL NUMBER 917.256541 and notes that the model and serial numbers are found on a plate under the seat. The model number identifies the tractor family and configuration; the serial number is what’s used to narrow down production details.
Quick reference: model number vs. serial number
| Identifier | What it tells you | Where to find it |
|---|---|---|
| 917256541 (model number) | Which Craftsman tractor design you have | Plate under the seat; also on the manual cover |
| Serial number | The specific unit identifier used for dating and exact parts matching | Plate under the seat |
| Date of purchase | When it was bought (helpful for warranty and maintenance history) | Receipt or your records |
Why it matters
Getting the year right helps you order the correct repair parts and maintenance items (belts, blades, mandrel parts, and electrical components) for your exact build, especially when there are mid-series changes.
If you are ordering parts, start with the parts list for model 917256541, or search by model on Sears PartsDirect.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917256541, a full engine replacement typically costs $800 to $2,500 installed (engine plus labor). Total price depends on the engine type, whether you replace the short block or the complete engine, and any extra parts needed during the swap; see the owner's manual for service and parts guidance.
What drives the total cost
- Engine choice: complete engine replacement usually costs more than internal repair
- Labor time: riding mower engine swaps commonly run 4 to 8 hours depending on access and rusted fasteners
- Extra parts: belts, pulleys, wiring repairs, fuel system parts, and hardware often add cost
- Root cause: overheating, low oil, or fuel contamination can damage more than the engine
- Shop rates: local labor rates and pickup/delivery fees vary
Typical price ranges (parts + labor)
| Repair path | What it includes | Typical total cost |
|---|---|---|
| Tune-up and diagnosis | Basic checks, plugs, filters, adjustments | $150 to $400 |
| Major internal repair | Partial teardown, internal parts, reassembly | $500 to $1,500 |
| Engine replacement | Remove and replace engine, setup and test | $800 to $2,500 |
| Short block replacement | Replace internal engine assembly, reuse externals | $1,200 to $3,000 |
When replacement makes sense
Replacement is the best value when the engine has low compression, severe internal noise, thrown rod, or repeated oil contamination. If the tractor also has drive or deck issues, we recommend pricing those repairs at the same time so you do not invest in an engine and still have poor cutting or traction.
Parts you may end up replacing during an engine job
Even though these are not engine parts, they are commonly addressed during major service because they affect performance and reliability:
- V-belt 532138255 (ground drive belt)
- Lawn tractor drive belt 532144200 (blade drive belt)
- Lawn tractor blade idler pulley 532139245
- Husqvarna lawn tractor mandrel assembly 532130794 (if the deck has vibration or bearing noise)
Why it matters
A riding mower engine replacement is a big investment; confirming the real cause of the failure (fuel, oil level, cooling fins, wiring, or safety interlocks) helps prevent the new engine from developing the same problem. For maintenance intervals and troubleshooting steps, use the owner's manual.
If you decide to move forward, you can price and order parts from the parts list for model 917256541, or search by model number on Sears PartsDirect.

How to look up Craftsman model number?
For Craftsman riding tractors like model 917256541, we look up the model number on the identification plate under the seat. Once you have the model number (and serial number), you can match the correct parts list and maintenance information in the owner's manual.
Where to find the model and serial number
On Craftsman model 917256541, the identification plate is located under the seat.
- Park on a flat surface and set the parking brake
- Turn the key off and remove it
- Lift the seat and look for the ID plate or sticker on the frame area under the seat
- Write down both the model number and serial number
- Keep the numbers with your purchase records for future reference
How to use the number to find the right parts
Using the exact model number prevents ordering the wrong belt, blade, or deck parts.
| What you have | What it helps you do | Example for this tractor |
|---|---|---|
| Model number | Pulls the correct diagrams and parts list | 917256541 |
| Serial number | Confirms production version when parts changed mid-run | Use the exact serial from the plate |
| Product type | Narrows results if you search broadly | Craftsman front-engine lawn tractor |
Common mix-ups to avoid
These issues cause the most wrong-part orders:
- Confusing the model number with an engine model number
- Reading a worn label and swapping digits (for example, 917.256541 vs 917256541)
- Using a deck size guess instead of the model number
- Searching by a part description only (like “drive belt”) without the model
Why it matters
Your model number ties directly to the correct repair parts and specs. For example, routine wear items like the lawn tractor drive belt 532144200 and the husqvarna lawn tractor mulching blade, 21-in 532134149 must match the exact tractor configuration to fit and operate correctly.

What model number is a Craftsman 6.75 lawn mower?
“6.75” is an engine power rating, not a Craftsman model number. The model number is the full ID printed on the mower’s product label; for a Craftsman riding tractor, it is typically a 9-digit number like 917256541. Use the 917256541 owner's manual to confirm the exact label location and how the number is recorded.
How to identify the correct model number
Use the product label, not the engine cover or advertising decals.
- Look for a label that lists Model and Serial
- Write the model number exactly as shown (all digits, no spaces)
- Record the serial number too; it helps with parts variations
- If the label is dirty, wipe it clean and take a photo for reference
Where the model number is usually located (Craftsman tractors)
On Craftsman front-engine lawn tractors like model 917256541, the ID label is commonly found in one of these areas:
- Under the seat on the frame
- On a frame rail near the rear wheel
- Near the rear fender pan
- Under the hood area on the chassis (less common)
“6.75” vs model number: quick comparison
| Marking you see | What it identifies | Use it for parts lookup? |
|---|---|---|
| 6.75 | Engine power rating | No |
| 917256541 | Craftsman product model number | Yes |
| Serial number | Production identifier | Sometimes |
Why it matters
Many different Craftsman mowers can share a “6.75” engine rating, but parts like belts, blades, and pulleys are matched to the exact model number. For example, tractor drive components such as the v-belt 532138255 must be selected by model-specific fit.
Ordering the right parts
- Use the parts list for model 917256541 first
- If you are shopping for a different Craftsman mower, search by its full model number on Sears PartsDirect
- Match deck and drive parts by the exact configuration shown in the manual diagrams
