How to look up Craftsman model number?
For a Craftsman front-engine lawn tractor like model 917253642, the model number is printed on the product identification label. On most tractors, you will find that label under the seat or on the frame near the rear wheels. Use the exact model number to match the correct parts list and diagrams.
Where to check on a riding lawn tractor
- Under the seat (lift the seat and look for a sticker or metal tag)
- On the frame rail near the rear axle
- Under the hood near the engine compartment (less common)
- Near the footrest area on the chassis (varies by build)
What to write down (and why)
The ID label usually includes more than just the model number. Recording all fields helps you get the right Craftsman riding mower and tractor parts.
| Label item | Example | Why it matters |
|---|---|---|
| Model number | 917253642 | Matches the correct parts diagrams |
| Serial number | (varies) | Helps confirm production run details |
| Product/PNC/type code | (varies) | Useful when multiple versions share a model family |
How to use the model number to find parts
- Enter 917253642 exactly as shown on the label (include all digits)
- Use the parts diagrams to identify the assembly first (mower deck, steering, electrical)
- Then match the part name and identifier before ordering (for example, blades, belts, or ignition parts)
If you are doing maintenance or troubleshooting, the 917253642 owner's manual is also the best place to confirm service intervals and adjustment procedures.
Why it matters
Craftsman tractors often have similar-looking decks, blades, and electrical components across nearby model numbers. Using the exact model number prevents ordering a blade, belt, or ignition switch that fits a different deck size or configuration.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman 917253642 front-engine lawn tractor is worth it when the tractor’s deck, steering, and drive system are still solid and the total engine-swap cost stays well below the cost of replacing the whole machine. If the deck is rusted through or the drivetrain is failing, put the money into a replacement tractor instead.
Quick decision checklist
We use these practical checks to decide fast:
- Deck condition: no cracks, no severe rust-through, and the spindles/mandrels mount securely
- Drive system health: tractor moves strongly forward and reverse without slipping or whining
- Parts support: common wear items (blades, belts, cables, electrical) are still available for 917253642
- Total cost: engine + any “while you’re in there” parts is under ~50% of a comparable replacement tractor
- Time and tools: you can safely lift/support the tractor and handle fuel, wiring, and controls
Costs that change the math (what to include)
An engine swap often triggers other needed repairs. Budget for the items below if they are worn.
| Item to evaluate | Why it matters | Example part on this model page |
|---|---|---|
| Deck spindle/mandrel area | Worn mandrels cause vibration and poor cut | Lawn tractor mandrel housing 587819701 |
| Blade engagement controls | A stretched cable can prevent proper PTO engagement | Husqvarna lawn tractor blade clutch cable 532435111 |
| Starting circuit | No-crank issues can look like “bad engine” | Lawn tractor starter solenoid 582042802 |
| Ignition controls | Intermittent start/run problems can be switch-related | Lawn tractor ignition switch 532193350 |
Safety and “worth it” go together
If you proceed, we follow the same safety basics called out in the owner's manual: disengage the PTO, set the parking brake, stop the engine, remove the key, and disconnect the spark plug wire(s) before working. That keeps an engine swap from turning into an injury.
Why it matters
A replacement engine can extend the life of a good mower deck and chassis for years, but it does not fix underlying problems like a failing transmission, unsafe guards/shields, or chronic vibration from worn deck components. Evaluating the whole tractor first prevents spending engine money on a machine that still will not mow reliably.

What engine does Craftsman riding mower use?
The Craftsman front-engine lawn tractor model 917253642 uses a gasoline engine, but the exact engine brand and horsepower rating vary by build and are identified on the engine label and in the 917253642 owner's manual. Use your model and serial details to match the correct tune-up and starting parts.
How to identify the exact engine on model 917253642
Check these locations on your tractor:
- Engine shroud or valve cover label (often lists brand, displacement, and model/type code)
- Blower housing tag near the starter or spark plug
- Frame tag for the tractor model and serial number (helps confirm the correct parts diagrams)
- The engine’s model-type-code (common format on many small engines)
Quick ID checklist
| What you find | What it tells you | What to do next |
|---|---|---|
| Engine model/type code | Exact engine family and spec | Use it to match filters, plugs, belts, and electrical parts |
| Only tractor model number (917253642) | Tractor configuration | Use the parts diagrams and the manual for maintenance intervals |
| Missing/illegible label | Harder to confirm engine spec | Match by tractor serial range and existing part numbers |
Parts that commonly relate to engine starting (and why)
If the question is really about starting or cranking issues, these parts are frequent culprits on riding mowers:
- Lawn tractor ignition switch 532193350 (no crank, intermittent power)
- Lawn tractor starter solenoid 582042802 (clicking, no starter engagement)
- Battery cables and connections (voltage drop, weak crank)
- Safety interlock switches (no crank when brake or PTO conditions are not met)
Why it matters
The correct engine identification ensures you buy the right maintenance items (spark plug, air filter, oil type) and diagnose problems correctly. For example, a “clicks but won’t turn over” symptom often points to the battery/solenoid circuit, not the engine itself.
Helpful DIY guidance
For step-by-step troubleshooting, use riding lawn mower engine clicks but doesnt turn over video.

Who makes the motors for Craftsman lawn mowers?
For the Craftsman front-engine lawn tractor model 917253642, the engine supplier varies by the specific engine installed on the tractor; Craftsman commonly used engines from Briggs & Stratton, Kohler, and Kawasaki across different mower and tractor models. The quickest way to confirm yours is to match the engine ID tag to the engine section in the 917253642 owner's manual.
How to identify the engine manufacturer on your 917253642
Look for an engine identification label (usually on the blower housing, valve cover area, or near the starter). Use these checks:
- Write down the engine brand shown on the shroud (Briggs & Stratton, Kohler, Kawasaki).
- Record the engine model and type/spec numbers from the label.
- Compare those numbers to the engine information and service sections in the 917253642 owner's manual.
- If the label is dirty, wipe it gently; avoid spraying water directly into the engine area.
- Use the engine model/type to select tune-up parts (spark plug, air filter, fuel filter) that match your exact engine.
Why the engine maker can differ (even within Craftsman)
Craftsman is the equipment brand, but riding mower and lawn tractor engines are sourced from multiple engine manufacturers. That means two Craftsman tractors that look similar can have different ignition systems, carburetors, and maintenance parts.
What changes based on engine brand
Use this as a practical guide for what you should verify before ordering engine-related parts:
| What you’re working on | What to match | Why it matters |
|---|---|---|
| Tune-up parts | Engine model/type/spec | Prevents wrong plug or filter fit |
| Starting problems | Battery, wiring, ignition switch, solenoid | Different engines still share common tractor-side parts |
| Fuel issues | Fuel line routing, tank, shutoff valve (if equipped) | Avoids leaks and hard-starting |
Helpful related troubleshooting
If the engine clicks but won’t crank, focus first on the tractor-side starting circuit (battery connections, solenoid, ignition switch). These parts are commonly replaced on this model:
- Lawn tractor starter solenoid 582042802
- Lawn tractor ignition switch 532193350
- Lawn tractor ignition harness 532401098
For step-by-step diagnosis, use riding lawn mower engine clicks but doesnt turn over video.
Why it matters
Confirming the engine manufacturer and engine ID prevents ordering the wrong maintenance parts and speeds up troubleshooting when the tractor won’t start, won’t crank, or runs poorly.
