What model number is a Craftsman 917271750 lawn mower?
The model number for this Craftsman riding lawn tractor is 917.271750 (often written without the dot as 917271750). You can confirm it on the tractor’s model label and in the 917271750 owner's manual.
We recommend checking these common locations on Craftsman lawn tractors:
- Under the seat on the seat pan or frame
- On the rear fender pan near the seat
- On the frame rail near the engine compartment
- Near the transaxle area (rear of the tractor)
- Inside the hood area on the chassis
They refer to the same model; the dot is just formatting used in some manuals and labels.
| How it may appear | What it means |
|---|---|
| 917.271750 | Model number with a dot (manual/label format) |
| 917271750 | Same model number without the dot (parts lookup format) |
Using the exact model number ensures you get the right diagrams, parts, and specs for your tractor, especially for deck and drive components like the v-belt 532138255 and mower deck parts.
Match these details to avoid mix-ups with similar Craftsman tractors:
- Product type: front-engine lawn tractor (riding mower)
- Deck size: typically listed as 42 in. on this model’s documentation
- Engine rating: commonly listed as 18.0 HP in the manual
- Always match the full model number (all digits)

What year did Craftsman make the 917271750?
The Craftsman lawn tractor model 917.271750 is from the early 2000s era (commonly associated with Craftsman LT1000-style tractors), and the most reliable way to confirm the exact production year is by matching your tractor’s product identification label details to the specifications in the 917271750 owner's manual.
We use the model number to identify the correct parts and diagrams, but the build year is tied to the product ID/serial information on the tractor.
- Look for the product identification label under the seat, on the frame rail, or near the rear fender area.
- Record the serial number and any date code shown.
- Compare the engine and drivetrain identifiers to the manual’s component listings (for example, the manual shows a Briggs engine model 31H777 and a Peerless transaxle 206-545C for this tractor).
- If your tractor has had major replacements (engine, transaxle, hood), use the tractor label, not the replacement part label.
The documentation for model 917.271750 confirms the tractor’s configuration and major assemblies, which helps narrow the era and ensures you are looking at the right identification label.
| Item in documentation | What it helps confirm | Why it matters |
|---|---|---|
| Tractor model number 917.271750 | Correct platform | Prevents ordering mismatched parts |
| Briggs engine model 31H777 | Engine family used on this tractor | Helps cross-check ID label info |
| Peerless transaxle 206-545C | Drivetrain family | Helps confirm the correct tractor series |
Craftsman tractors can share similar styling across multiple years; the exact year affects small but important differences such as deck linkage, belt routing, decals, and chassis hardware. Confirming the year using the tractor’s ID label helps us match the right diagrams and parts the first time.

What kind of engine does a Craftsman riding lawn mower have?
The Craftsman lawn tractor model 917271750 uses a low-emission, 18.0 HP engine (gas) as specified in the 917271750 owner's manual. It is an electric-start riding mower designed to run best at full throttle for mowing performance and battery charging.
From the model-specific documentation, this tractor is described as:
- 18.0 HP lawn tractor
- 42-inch mower deck
- Electric start
- 6-speed transaxle
- Low-emission engine design (operates differently than older engines)
For normal mowing, we recommend following the operating guidance in the manual:
- Run the engine at full throttle while mowing
- Avoid idling on grass for long periods (hot exhaust can brown grass)
- Come to a complete stop before shifting gears to protect the transaxle
- Keep the engine and deck area clear of grass and debris buildup
| Item | What it means on this tractor |
|---|---|
| Engine rating | 18.0 HP (low-emission gas engine) |
| Starting system | Electric start |
| Deck size | 42-inch |
| Drive type | 6-speed transaxle |
Knowing the correct engine type and rating helps you buy the right tune-up parts (spark plug, air filter, fuel filter) and operate the tractor correctly. On the 917271750, full-throttle mowing also improves cut quality and keeps the battery charging properly.

Who makes Craftsman lawn mower engines?
For Craftsman lawn tractor model 917271750, the engine manufacturer is Briggs & Stratton. The parts list in the 917271750 owner's manual identifies the engine as Briggs model 31H777, which is the engine family used on this tractor.
We recommend verifying the engine ID on the engine itself so you get the right tune-up and repair parts.
- Lift the hood and locate the engine label (usually on the blower housing or valve cover)
- Write down the model, type, and code numbers from the label
- Match that information to the engine listing in the manual (Briggs model 31H777)
- Use the engine numbers when shopping for engine-specific parts (air filter, spark plug, carburetor parts)
- Use the tractor model 917271750 when shopping for chassis and deck parts (belts, blades, mandrels)
The tractor model number tells us the mower platform; the engine model tells us the engine parts.
| What you’re working on | Use this identifier | Examples |
|---|---|---|
| Engine parts | Briggs model number on the engine (31H777) | Spark plug, air filter, starter, carburetor |
| Tractor and mower deck parts | Craftsman model 917271750 | Deck belt, blades, mandrel, idler parts |
If you are troubleshooting cutting issues (like blades not rotating), these model-matched parts are common wear items:
- V-belt 532138255 (mower drive belt style used on many Craftsman/Husqvarna-built decks)
- Husqvarna lawn tractor mandrel assembly 532130794 (spindle/mandrel that turns the blade)
- Husqvarna lawn tractor mulching blade, 21-in 532134149 (blade option for compatible decks)
Briggs & Stratton engines use engine-specific service parts and settings; using the correct engine model (31H777) prevents wrong-part returns and helps ensure proper starting, power, and fuel economy.

Does a Craftsman riding mower have an oil filter?
Yes. The Craftsman riding mower model 917271750 is designed to use an engine oil filter (when equipped), and the maintenance schedule in the 917271750 owner's manual includes oil changes “with oil filter” plus a separate “replace oil filter (if equipped)” interval.
On this Craftsman lawn tractor, the quickest confirmation is a visual check on the engine.
- Park on a level surface, set the parking brake, and let the engine cool
- Open the hood and look for a spin-on canister-style filter on the side of the engine block
- If you see a filter, plan to change it at least every season (or every other oil change if you run over 100 hours per year)
- If you do not see a filter, follow the “without oil filter” oil-change schedule in the manual
- Always verify oil level with the dipstick after refilling
The manual lists different oil-change lines because some engine versions use a filter and some do not.
| Your engine setup | What to do at oil change time | Typical result |
|---|---|---|
| With oil filter | Change oil and replace the oil filter | Cleaner oil longer; better protection under load |
| Without oil filter | Change oil only | Oil needs changing more often |
An oil filter traps fine debris that accelerates engine wear. If your 917271750 has a filter, replacing it on schedule helps prevent loss of power, overheating, and premature engine damage.
- Check engine oil level before every use
- Clean or service the air filter (dirty filters cause poor running)
- Inspect the deck for grass buildup and loose fasteners
- Check V-belts for wear and cracking
