How to look up Craftsman model number?
On a Craftsman riding mower like model 917254450, you can look up the model number by finding the model plate under the seat; the manual for this tractor also notes the serial number is on the model plate under the seat. Use that exact model number when ordering parts or checking specifications in the 917254450 owner's manual.
Where to find the model and serial number
Check these common locations on Craftsman riding mowers and tractors:
- Under the seat on the frame (model plate or sticker)
- Underside of the seat pan (sometimes the label is attached to the seat itself)
- Near the rear fender or frame rail close to the seat mounting area
- Engine model number: typically on the engine blower housing (separate from the tractor model)
How to record it correctly (so parts match)
Write the information exactly as shown on the label.
- Copy the full model number (for this tractor: 917254450)
- Copy the serial number from the same plate
- If you are ordering engine parts, also record the engine model and type numbers
- Take a clear photo of the label before it fades or gets dirty
| What you are looking up | Where it’s found | What it’s used for |
|---|---|---|
| Tractor model number (917254450) | Model plate under the seat | Correct tractor parts diagrams and parts |
| Tractor serial number | Model plate under the seat | Production-specific identification |
| Engine model/type | Engine blower housing | Correct engine parts |
Why it matters
Craftsman tractors can look similar across years, but parts like belts, pulleys, tires, and switches can vary by model and serial range. Using the exact model number helps us match the right diagrams and replacement parts the first time.

What Craftsman lawnmower do I have?
Your Craftsman riding mower is identified by the model number on its product identification label. For this model page, the mower is a Craftsman 917254450 front-engine lawn tractor; match the number on your label to confirm it is the same unit.
Where to find the model number on a Craftsman tractor
On Craftsman tractors like model 917254450, the product identification label is commonly located under the seat area. Use the location and label details shown in the 917254450 owner's manual to confirm the exact spot and how the label is formatted.
- Park on a flat surface and set the parking brake
- Lift the seat and look on the underside of the seat or the seat support area
- Wipe dirt and grass off the label so the numbers are readable
- Write down the full model number exactly as printed
- Use the full model number (not the engine number) when ordering parts
What to record from the label (and why)
We recommend recording these items so you can get the right Craftsman parts (belts, pulleys, tires, switches) the first time.
| Label item | Example | What it’s used for |
|---|---|---|
| Model number | 917254450 | Correct parts diagrams and part compatibility |
| Product number (if shown) | Varies | Narrowing down exact configuration |
| Serial number | Varies | Service history and production run details |
Quick checks to confirm you are on the right model
If your label shows 917254450, you are on the correct parts list for this tractor. If it shows a different 917.xxxxx number, use that exact number instead because deck, transaxle, and drive components can differ.
- Model number matches 917254450 exactly
- Tractor is a front-engine riding mower/tractor style
- Parts and diagrams align with what you see on your machine
Why it matters
Craftsman tractors often share similar frames, but the mower deck setup, motion drive belt routing, and safety interlock wiring can vary by model. Using the correct model number helps ensure you get the right items, such as a lawn tractor seat switch 532421062 or a lawn tractor blade drive belt 532106085 when applicable.

What engine does Craftsman riding mower use?
For Craftsman model 917254450, the exact engine make and model is listed in the tractor’s documentation and on the engine ID label; this tractor uses a single-cylinder gasoline engine configuration typical of front-engine riding mowers. For the most accurate match when buying tune-up parts, we use the engine’s model-type-code numbers.
How to identify the engine on model 917254450
Use the 917254450 owner's manual to locate the engine identification area and confirm the correct engine information before ordering parts.
Check these common ID points:
- Engine shroud or blower housing (often near the recoil area or top cover)
- Valve cover area
- Frame rail near the engine (sometimes a secondary equipment label)
- Under the hood near the air intake and carburetor area (engine off and cool)
- Your tractor’s product label (model and serial; engine details may be separate)
What to write down (so parts match the first time)
Most small engines used on Craftsman front-engine tractors are identified by a set of numbers that look like:
| What you see on the label | What it means | Why we need it |
|---|---|---|
| Model | Engine family/model | Determines the correct parts list |
| Type | Build/spec variation | Prevents ordering the wrong carburetor, muffler, or starter |
| Code/Date | Production code | Helps match mid-year design changes |
Why it matters
Many Craftsman tractors share the same tractor model number but can ship with different engine variants over time. Using the engine label prevents mismatches on ignition parts, fuel system parts, and maintenance items.
Related safety and operation notes
The manual also calls out key engine-related safety items that affect troubleshooting and maintenance:
- Do not run the engine with the air cleaner or cover removed
- Do not operate without a muffler or with a damaged exhaust system
- Do not change governor settings or overspeed the engine
- Let the engine warm up before engaging the clutch or attachment

What kind of oil do you use in a Craftsman lawn tractor?
For the Craftsman lawn tractor model 917254450, use 4-cycle engine oil with the viscosity matched to temperature; the manual specifically calls for SAE 5W30 when temperatures are below 32°F (0°C). For warmer conditions, follow the viscosity chart in the 917254450 owner's manual.
Recommended oil type and viscosity
Use oil that meets API service classification SD, SE, or SF (as listed in the manual). Choose viscosity based on the temperature range you expect before the next oil change.
- Below 32°F (0°C): SAE 5W30 (protects the starting system in cold weather)
- Above 32°F (0°C): use the SAE viscosity grade chart in the manual
- Use 4-cycle (not 2-cycle) engine oil
- Keep the oil level at the FULL mark; do not overfill
- Check oil with the tractor on level ground and the engine off
Oil capacity and change intervals (model 917254450)
The manual lists a refill capacity of 1.4 liters (1-1/2 quarts) after draining.
| Maintenance item | When to do it | What to do |
|---|---|---|
| Break-in oil change | First 2 hours (about 2 mowings) | Drain warm oil, refill to spec |
| Oil level check | Every 5 hours (about 5 mowings) | Check level after engine stops; top off if needed |
| Routine oil changes | Follow your mowing schedule and conditions | Use the viscosity chart for your temps |
Why it matters
Correct oil viscosity helps your Craftsman tractor engine lubricate properly during cold starts and stay protected at operating temperature. Using the wrong viscosity can cause hard starting, extra wear, and overheating.
