How to look up Craftsman model number?
For Craftsman riding mowers like model 917257573, we look up the model number on the model plate under the seat. Once you have the model number and serial number, you can match the correct parts list and maintenance information in the owner's manual.
Where to find the model and serial number
On Craftsman tractors, the identification plate is located under the seat.
- Park on a flat surface, set the parking brake, and remove the key
- Lift the seat (or look at the frame directly under the seat)
- Find the plate that lists MODEL NUMBER and SERIAL NUMBER
- Write both down exactly as shown (including dots or dashes if present)
- Keep the numbers with your purchase and maintenance records
Tractor model number vs. engine model number
Your tractor and engine use different model numbers. This matters when ordering engine-specific parts (like ignition or fuel system items).
| What you are identifying | Where to find it | Example from this tractor’s manual |
|---|---|---|
| Tractor model number | Plate under the seat | 917.257573 (commonly written as 917257573) |
| Engine model number | Blower housing on the engine | Engine model and type are listed on the engine label |
Why it matters
Using the correct model number helps us match the right diagrams and parts for your exact deck, drive system, and steering setup. For example, parts like the seat 532401042 are model-matched, and using the wrong model number can lead to ordering a part that does not fit.

What are the most common issues with 917257573?
The most common issues we see on the Craftsman 917257573 front-engine lawn tractor involve belt wear (loss of drive or blades not engaging), uneven cutting from deck and spindle wear, and starting or safety-interlock problems. Use the owner's manual for model-specific checks, adjustments, and maintenance intervals.
Common problems and what they usually point to
- Tractor will not move or slips under load: worn or stretched drive belt, misrouted belt, or idler/tension issues
- Blades will not engage or stop cutting in tall grass: worn deck belt, weak idler spring, or pulley wear
- Uneven cut, vibration, or loud deck noise: bent/dull blade, worn mandrel (spindle) bearings, or loose hardware
- Poor discharge or clumping: dull blade, deck packed with wet grass, missing/bent deflector
- No crank or intermittent starting: ignition key wear, seat/brake safety switch issues, or wiring connections
Parts that commonly fix these symptoms
If your symptoms match, these are frequent wear items for this model:
- Lawn tractor drive belt 532144200 for loss of drive or slipping
- V-belt 532138255 for deck belt related engagement and cutting issues
- Lawn tractor blade idler pulley 532139245 when the belt squeals, jumps, or will not stay tensioned
- Husqvarna lawn tractor idler arm return spring 532105709 when belt tension feels weak
- Husqvarna lawn tractor mandrel assembly 532130794 for grinding noises, wobble, or persistent vibration
Quick checks we recommend before ordering parts
- Park on level ground; set parking brake; remove the key and disconnect the spark plug wire.
- Inspect belts for glazing, cracks, fraying, or a “narrowed” look.
- Spin deck pulleys by hand; roughness or play indicates bearing or mandrel wear.
- Confirm the blade is tight and not bent; clean packed grass from the deck.
- Test safety switches and wiring for looseness or damage.
Symptom-to-part guide
| Symptom | Most likely area | Common part to inspect |
|---|---|---|
| Slips or will not drive | Drive system | Drive belt |
| Blades will not stay engaged | Deck drive | Deck belt, idler pulley, spring |
| Vibration or rumble from deck | Spindles/mandrels | Mandrel assembly |
| Won’t start (intermittent) | Controls/safety | Key, switch |
Why it matters
Catching belt and mandrel wear early prevents thrown belts, damaged pulleys, and poor cut quality; it also reduces strain on the engine and deck components.

What year is Craftsman Model 917257573?
The model number 917257573 identifies the Craftsman tractor family and parts breakdown, but it does not tell the exact build year by itself. To find the year, we use the date/serial information on the product identification label and confirm it using the 917257573 owner's manual.
Where to find the build date information
On Craftsman front-engine lawn tractors, the product identification label is typically in one of these spots:
- Under the seat pan
- On the frame near the rear wheels
- Under the hood near the engine compartment
- Near the steering column area
How to determine the year (practical steps)
Use this process so the date code is readable and complete:
- Clean the label so every character is visible
- Write down the serial/date code exactly (include letters, dashes, and spaces)
- Look for a field labeled DOM, Date, or a grouped numeric code
- Compare what you recorded to the identification information in the 917257573 owner's manual
- Use the full model and date/serial code together when selecting parts
Common date-code formats you may see
These are the most common patterns on riding mower and tractor ID labels.
| Label format | How it reads | Example |
|---|---|---|
| 6 digits in a row | Often MMDDYY | 072811 = July 28, 2011 |
| Separate “DOM” or “Date” field | Direct manufacture date | Read as printed |
| Letters plus numbers | Series/plant plus date info | Match by pattern in the manual |
Why it matters
The build year and full ID label information helps us match the correct configuration for your tractor, especially when parts change during a production run.
Parts that commonly vary by production run
- Ground drive belt (example: v-belt 532138255)
- Deck drive belt (example: lawn tractor drive belt 532144200)
- Ignition components (example: molded ignition key 532140403)
- Electrical items such as switches (example: switch 532158913)
