How to look up Craftsman model number?
To look up the model number for your Craftsman riding mower, find the model/serial tag on the tractor and use that exact model number (for example, 917256712) when searching parts diagrams and replacement parts on Sears PartsDirect.
On most Craftsman front-engine lawn tractors, the model and serial number label is typically located in one of these spots:
- On the frame under the seat
- On the underside of the seat
- Near the rear fender area around the seat mounting points
- On the frame rail close to the engine (less common)
Once you have the model number, match it exactly (all digits) to avoid ordering the wrong belt, switch, or steering part.
- Enter the full model number (example: 917256712)
- Use the parts diagrams to confirm fit by location and description
- Compare the part name and part ID before ordering
- If your tag is hard to read, clean it and take a photo, then zoom in
| What you are replacing | What to look for in the parts list | Example part on this model page |
|---|---|---|
| Mower will not move | Ground drive belt length/width | Lawn tractor ground drive belt, 1/2 x 82-in 532140294 |
| Blades will not engage | PTO switch and wiring connections | Switch.pto.3 582107601 |
| Key is missing | Ignition key style | Molded ignition key 532140403 |
Craftsman tractors often look similar across multiple years and deck sizes, but belts, pulleys, tires, and electrical switches can vary by model. Using the exact model number helps ensure the replacement part matches your tractor’s configuration.

Here are a few examples from the parts available for 917256712:
| Repair need | Part to look for | Example part anchor |
|---|---|---|
| Tractor will not move or slips | Ground drive belt | Lawn tractor ground drive belt, 1/2 x 82-in 532140294 |
| Blades will not engage | PTO switch | Switch.pto.3 582107601 |

How do I tell what year my lawn mower is?
For your Craftsman front-engine lawn tractor model 917256712, the most reliable way to tell the year is to read the product identification label (model and serial number) on the tractor and use the serial number format to determine the build date.
On most Craftsman riding mowers and lawn tractors, the ID label is typically in one of these spots:
- Under the seat (seat pan or frame rail)
- On the rear fender pan near the seat
- On the frame near the engine compartment
- On the mower deck shell (less common for the main tractor ID)
If the label is dirty or faded, wipe it with a damp rag first so the serial characters are readable.
Once you have the serial number, look for a date code pattern. Common formats you may see include:
- MMDDYY (month, day, year)
- YYMMDD (year, month, day)
- A longer serial where a 2-digit year appears early in the string
| Serial snippet style | Example | What it indicates |
|---|---|---|
| MMDDYY | 041518 | Built April 15, 2018 |
| YYMMDD | 180415 | Built April 15, 2018 |
| Embedded year | XX18XXXX | Built in 2018 |
If your serial number does not match a clear date pattern, use the parts list for model 917256712 to cross-check production era by looking at original equipment components and revisions.
When the serial number format is unclear, matching key components can help narrow the timeframe. For example, you can compare what is installed on your tractor to common wear parts listed for this model, such as the switch.pto.3 582107601 or the lawn tractor ground drive belt, 1/2 x 82-in 532140294.
Knowing the build year helps us match the correct Craftsman parts, wiring, belts, and safety interlock components, especially when a model has multiple production runs with small changes.
For ordering, we recommend using the model number 917256712 and your serial number when searching parts on this model’s list first, or on Sears PartsDirect if you are searching across models.

What engine does Craftsman riding mower use?
Craftsman riding mower model 917256712 uses a single-cylinder gasoline engine (a common setup for front-engine lawn tractors). The exact engine brand, displacement, and horsepower can vary by production run and engine spec code, so we match engine-related replacement parts by the 917256712 model parts list on Sears PartsDirect.
Use the engine ID tag on the engine itself (not the mower model tag). On most riding mowers, it’s on the blower housing, valve cover area, or near the starter.
- Write down the engine manufacturer (often Briggs & Stratton, Kohler, or Tecumseh on older units)
- Record the full engine model / type / code (or spec number)
- Compare that info to the engine-related diagrams and parts list for 917256712
- If your mower has hard starting or no-crank symptoms, check the safety interlocks and ignition switch circuit
- For PTO engagement issues, confirm the PTO switch is working and the wiring connectors are tight
Even when the engine itself is fine, these parts often cause symptoms that feel like an engine problem (no crank, stalls, blades will not engage):
| Symptom | Common area to check | Example part on this model page |
|---|---|---|
| Key turns, nothing happens | Ignition switch, battery cables, safety switches | Molded ignition key 532140403 |
| Engine runs, blades will not engage | PTO switch, deck belt, idlers | Switch.pto.3 582107601 |
| Engine runs, tractor will not move | Ground drive belt, idlers, linkage | Lawn tractor ground drive belt, 1/2 x 82-in 532140294 |
Engine families share similar-looking parts, but small differences in spec codes change items like ignition components, carburetor linkages, and charging systems. Using the mower model 917256712 plus the engine’s model/type/code ensures you get the right Craftsman-compatible parts the first time.
For a fast diagnosis when the starter clicks or the engine will not crank, follow riding lawn mower engine clicks but doesnt turn over video.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman riding tractor model 917256712 is worth it when the tractor’s deck, steering, and transmission are in good shape and the total engine swap cost stays under about half the tractor’s current value.
- The mower deck is solid (not rusted through) and the mandrels spin smoothly.
- The transmission drives normally (no slipping, no loss of forward or reverse).
- Steering and front end are tight (no severe play).
- The problem is truly engine-related, not a no-start caused by fuel, spark, or safety interlocks.
- You are comfortable doing some DIY work or keeping labor costs low.
Engine replacement makes sense when the all-in cost (engine, small parts, labor) is under about 50% of the tractor’s value.
| Condition of tractor | Best move | Why it matters |
|---|---|---|
| Chassis, deck, and drive are strong | Replace engine | Extends life of a known-good tractor |
| Deck and transmission are both worn | Replace tractor | Avoids stacking major repairs |
| Cranks but will not start | Diagnose first | Often not an internal engine failure |
A “bad engine” is often a starting or engagement issue. Use these common checks first:
- Battery charged; cables clean and tight
- Fresh fuel and clear fuel flow
- Strong spark at the plug
- Safety interlocks and PTO circuit working (a failed switch.pto.3 582107601 can prevent starting or shut the engine off)
For step-by-step help, use riding lawn mower engine spins but wont start video.
An engine swap is a big investment; confirming the tractor’s deck and drivetrain are worth saving prevents spending engine money on a tractor that still will not cut or drive reliably.
You can order model-specific replacement parts for 917256712 from the parts list, or search by model number on Sears PartsDirect.
