How to look up Craftsman model number?
To look up the correct parts for your Craftsman riding mower, we use the model number from the tractor’s ID label. On Craftsman model 91725300 (super 12 hydro-trac tractor), the model and serial label is typically on the frame under the seat or on the underside of the seat.
Where to find the model number on a Craftsman riding mower
Check these common locations first:
- Under the seat on the frame rail (lift the seat and look at the chassis)
- Underside of the seat pan (tilt the seat forward and inspect the bottom)
- Rear fender or rear frame area near the seat mounting points
- Near the engine compartment on the frame (less common)
How to use the model number once you find it
Use the model number exactly as printed (letters, numbers, and dashes if shown).
- Match the model number to the parts list for your tractor
- Use the model number to confirm fit for belts, pulleys, wheels, and hardware
- If the label is worn, clean it gently and use a flashlight to read stamped characters
Quick checklist
| What to capture | Why we need it |
|---|---|
| Model number (example: 91725300) | Identifies the exact tractor configuration |
| Serial number | Helps confirm production run and compatible revisions |
| Engine model (if listed) | Helps match engine-specific parts like filters and ignition parts |
Why it matters
Craftsman riding mowers often share similar looks across multiple series, but parts like a ground drive idler pulley, axle bearing, or wheel hardware can vary by model. Using the exact model number helps prevent ordering the wrong part.
Example of model-matched parts you might see for 91725300
If you are already shopping parts for this tractor, these are examples of model-specific items that can appear in the parts list:
- Flange bearing 532009040 (front axle support)

What brand engine does Craftsman use?
Craftsman riding mowers and lawn tractors use engines from several major manufacturers, most commonly Briggs & Stratton, with some models using Kohler or Kawasaki. For your Craftsman model 91725300 (super 12 hydro-trac tractor), the exact engine brand is best confirmed from the engine ID tag on the engine itself.
How to identify the engine brand on model 91725300
Look for an engine identification label (usually on the blower housing, valve cover, or near the starter). Use these quick checks:
- Find the engine manufacturer name (Briggs & Stratton, Kohler, Kawasaki, etc.)
- Write down the engine model and type/spec numbers
- Check the valve cover shape and air filter housing style (often brand-specific)
- Match the engine numbers when ordering tune-up parts (spark plug, air filter, fuel filter)
- If the label is missing, use the tractor’s frame tag plus engine photos to narrow it down
Common engine brands used on Craftsman tractors
Craftsman has sourced engines from multiple suppliers over the years. Here is what we see most often on riding mowers and tractors:
| Engine brand | Typical use on Craftsman equipment | What you’ll see on the label |
|---|---|---|
| Briggs & Stratton | Very common on many Craftsman tractors | Model and type numbers (often two lines) |
| Kohler | Common on mid to higher output tractors | Model and spec numbers |
| Kawasaki | Less common, often on premium models | Model code and serial number |
Why it matters
The tractor model number (91725300) helps us match chassis and drive parts, but engine parts are matched by the engine’s model/spec numbers. Confirming the engine brand prevents ordering the wrong carburetor parts, ignition parts, or filters.
Parts tip while you’re servicing the tractor
If you’re also addressing steering or front axle wear while doing engine maintenance, a worn bearing can cause sloppy steering and uneven tire wear. The flange bearing 532009040 is one of the front-end wear items commonly replaced during a refresh.

What year is Craftsman model 91725300?
Craftsman model 91725300 is a model number, not a date code; it does not directly tell the year. To find the year your Craftsman riding mower was built, we use the product’s date code (often on the ID tag) or the engine model and code stamped on the engine.
Where to find the build year information
Check these common locations on a Craftsman front-engine lawn tractor like model 91725300:
- Under the seat pan or on the seat support
- On the frame near the rear fender or left rear wheel
- Under the hood near the dash tower
- On the engine shroud (engine model/type and a separate date or code)
- On a sticker/plate that also lists serial information
How to decode the date once you find it
Many Craftsman-built riding mowers use a separate date code that can be read as month, day, year (for example, MMDDYY). Once you locate that code, the last two digits typically indicate the year.
Quick example (format only)
| Code format | Example | What it means |
|---|---|---|
| MMDDYY | 072811 | July 28, 2011 |
| MMDDYY | 041506 | April 15, 2006 |
Why it matters
The build year helps us match the correct parts and revisions for your tractor, especially for wear items like belts, steering hardware, and front axle components.
Parts that commonly depend on the exact build/version
- Front axle and steering bushings/bearings
- Ground drive idlers and pulleys
- Wheels, tires, and hub hardware
- Electrical items (switches, gauges)
If you are already working on the front end, the flange bearing 532009040 is one of the model-matched parts we commonly see used around axle and wheel support points.
