How do I identify my Craftsman lawn mower?
To identify your Craftsman riding mower or tractor, match the model number on the product ID label to your parts listing; for this page, the model is 91757591. On most Craftsman riders, the label is under the seat (often on the underside of the seat or the seat pan).
Where to look for the model and serial label
Check these common locations first (clean off grass and dirt so the numbers are readable):
- Under the seat: flip the seat forward and look on the underside or seat pan
- Frame rails near the rear wheels or under the fender
- Under the hood near the engine compartment (less common)
- Near the footrest area on the chassis (varies by design)
What numbers you need (and how to use them)
For ordering parts and confirming fitment, we use the model number first, then the product number and serial if present.
| Label item | What it does | Example format |
|---|---|---|
| Model number | Primary identifier for parts diagrams | 91757591 |
| Serial number | Helps confirm production run | Letters and numbers |
| Engine model/type/code | Used for engine-specific parts | Varies by engine brand |
Quick checks to avoid ordering the wrong parts
These steps help when the tractor has been repowered, modified, or has missing decals:
- Confirm the model number is exactly 91757591 (all digits, no spaces)
- Compare your tractor’s key features (deck size, transmission type, attachment setup)
- If you are working on a hitch or attachment connection, compare your hardware to common items like a hitch pin, 2-pack 596919601
- If you are servicing linkage or detent-style mechanisms, compare to small hardware items like a ball 532100482
Why it matters
Craftsman tractors can look similar across multiple model series, but parts like belts, blades, spindles, and hitch hardware often change by model and production run. Using the exact model number keeps your parts match accurate and reduces returns.

How to look up Craftsman model number?
To look up the model number for your Craftsman equipment, we first locate the model number tag on the machine, then use that exact number (for example, 91757591) to search parts diagrams and compatible replacement parts such as the ball 532100482.
Where to find the model number on a Craftsman riding mower or tractor
On most Craftsman riding mowers and lawn tractors, the model and serial number label is typically found in one of these spots:
- On the frame under the seat
- On the underside of the seat pan
- Near the rear frame rails behind the seat (visible when the seat is raised)
- On the fender pan area near the seat mounting points
How to use the model number to look up parts
Once you find the tag, copy the model number exactly as shown (including any leading zeros). Then:
- Search using the full model number (example: 91757591)
- Match the product category (riding mowers and tractors vs. tillers and attachments)
- Use the parts diagrams to confirm fit before ordering
- Compare the part name and part ID when selecting a replacement
Quick checklist: model number vs. serial number
| Item | What it does | Example | Why you need it |
|---|---|---|---|
| Model number | Identifies the design family | 91757591 | Ensures correct parts list |
| Serial number | Identifies your exact unit | Varies | Helps confirm production run |
Why it matters
Craftsman model numbers often look similar across different tractors and attachments; using the exact model number prevents ordering the wrong hardware, hitch parts, or drivetrain components.

What year is a Craftsman 91757591 riding mower?
The Craftsman model 91757591 does not map to one single “model year”; Craftsman tractors were often sold across multiple seasons with the same base model number. The most accurate way to date it is by using the product identification label (model and serial) on the tractor and matching the serial to the manufacturer’s date code.
Where to find the date information on model 91757591
Check these common locations on Craftsman riding mowers and tractors:
- Under the seat pan or on the seat support
- On the frame rail near the engine
- Near the rear hitch plate or transaxle area
- Under the hood near the dash tower
- On a fender well (inside edge)
If the label is damaged or missing, replacing missing hardware like a hitch fastener can help you reassemble safely after inspection; for example, a hitch pin, 2-pack 596919601 is a common retention pin used on tow points and attachments.
How to estimate the year when you only have the model number
For Craftsman model numbers that start with 917, the tractor was commonly built by a major OEM (often AYP/Husqvarna-built platforms) and sold for multiple years. Use this quick process:
- Record the full model number (91757591) and the full serial number from the ID label.
- Look for a separate engine model and code on the engine shroud (Briggs & Stratton, Kohler, etc.).
- Use the engine code date as a practical “not earlier than” build date for the tractor.
What the numbers usually tell you
| What you have | What it can tell you | Accuracy |
|---|---|---|
| Model number (91757591) | Product family and parts platform | Medium |
| Tractor serial number | Build date range when decoded | High |
| Engine date code | Engine manufacture date (helps bracket tractor age) | Medium to high |
Why it matters
Knowing the build timeframe helps us match the correct parts diagram and avoid ordering the wrong steering, deck, or hitch components. It also helps when selecting wear items and attachment hardware such as a ball 532100482 used in linkage or steering-related assemblies on many lawn and garden platforms.

Where is Craftsman's model number?
On Craftsman model 91757591, the model number is on the product identification label attached to the equipment frame or chassis (not on the engine). We use that exact model number to pull the correct parts diagrams and ensure replacement parts fit.
Where to look on model 91757591
Check these common label locations; clean off grass and dirt so the numbers are readable:
- Under the seat or on the seat support bracket
- On the frame rail near the footrest area
- On the rear fender area near the seat
- Under the hood area on the chassis
- Along the main frame near the front axle
What to record from the label
Write down every identifier shown so you can match the right Craftsman parts:
- Model number (example: 91757591)
- Serial number (helps confirm the exact build)
- Product number (sometimes listed in addition to the model)
- Engine model/type/code (only needed when ordering engine-specific parts)
Quick reference
| Label item | What we use it for | Example format |
|---|---|---|
| Model number | Matching equipment parts diagrams | 91757591 |
| Serial number | Narrowing version/build | Letters and numbers |
| Engine numbers | Matching engine parts | Model/type/code |
Why it matters
Craftsman equipment can have multiple versions that look similar but use different hardware. Using the exact model number helps prevent ordering the wrong fit-critical items such as a hitch pin, 2-pack 596919601 or a ball 532100482.

Who makes engines for Craftsman lawn mowers?
Craftsman lawn mowers and front-engine lawn tractors (including model 91757591) have used engines supplied by multiple manufacturers over the years; the most common are Briggs & Stratton, Kohler, and Kawasaki. The exact engine maker depends on the specific Craftsman model and engine ID tag.
How to identify the engine manufacturer on your Craftsman 91757591
Look for the engine identification label, then match the brand and model/type numbers.
- Check the engine shroud (top cover) for a brand badge or decal
- Look near the starter, valve cover, or blower housing for an ID label
- Record the engine model/type/code (Briggs & Stratton) or spec number (Kohler) or model/spec (Kawasaki)
- Use those numbers when ordering tune-up parts like filters, spark plugs, and belts
- If the label is missing, use the tractor model number 91757591 plus the engine mounting layout to narrow it down
Common engine suppliers you may see (and what it affects)
Different engine brands can use different maintenance parts even when the tractor looks the same.
| Engine brand | What you’ll typically see on the label | Why it matters for parts |
|---|---|---|
| Briggs & Stratton | Model / Type / Code | Air filter, carburetor parts, ignition parts vary by code |
| Kohler | Model / Spec / Serial | Spec number drives the correct kit and gasket selection |
| Kawasaki | Model / Spec | Filters and tune-up parts are brand-specific |
Why it matters
Ordering by the engine ID prevents wrong-part returns and helps you get the right maintenance items (air filter, fuel filter, spark plug) and repair parts (carburetor, starter, ignition coil) the first time.
