How to find Craftsman model number?
On a Craftsman riding mower like model 917288573, we typically find the model and serial number on the tractor frame under the seat, or on a label on the underside of the seat. Use that exact model number to match the correct parts list and diagrams in the 917288573 operator's manual.
Where to look on the tractor
Check these common ID-label locations first:
- On the frame directly under the seat (lift the seat up)
- On the underside of the seat pan
- Near the rear fender area close to the seat mount
- On the frame rail near the battery tray (if equipped)
- On the mower deck shell (sometimes a separate deck tag)
What to write down (and why)
Record the information exactly as printed so parts fit the first time.
- Model number (example format in the manual: 917.28857; your parts model is 917288573)
- Serial number (unique to your tractor)
- Any product number or engine model/type/code listed on nearby labels
Quick ID checklist
| Item | What it does | Example you might see |
|---|---|---|
| Model number | Matches the correct parts diagrams | 917288573 |
| Serial number | Identifies production run details | Varies |
| Engine ID | Helps match engine tune-up parts | Varies |
Why it matters
Craftsman tractors often have multiple versions that look similar but use different belts, blades, and steering parts. Using the exact model number helps us match the right components, such as the correct deck blade like the 46-in deck high-lift blade 532405380 or the correct blade belt like the blade drive belt 584453101.

What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917288573 uses a low-emission internal combustion (gas) engine. We recommend using fresh gasoline with up to 10% ethanol (E10) and following the operating and maintenance guidance in the 917288573 owner's manual to keep starting, power, and cutting performance consistent.
What “kind of engine” means on this model
On the 917288573 tractor, “engine type” typically refers to fuel and emissions design rather than a specific brand name.
- Gas-powered internal combustion engine (not electric)
- Low-emission engine design (operates a bit differently than older engines)
- Electric start system
- Designed to run on gasoline up to E10 (10% ethanol)
Fuel guidance (what to use and what to avoid)
Using the right fuel helps prevent hard starting, surging, and poor power under load.
| Fuel type | OK to use? | Notes |
|---|---|---|
| Regular unleaded gasoline | Yes | Use fresh fuel for best results |
| Gasoline with up to 10% ethanol (E10) | Yes | Acceptable for this tractor |
| Gasoline over 10% ethanol | No | Avoid to prevent performance and warranty issues |
Why it matters
Low-emission small engines are more sensitive to stale fuel, incorrect throttle use, and maintenance lapses. Correct fuel and proper operation help the engine run at full governed speed, which also improves mower deck performance and grass discharge.
Related maintenance that protects the engine
These basics reduce no-start and poor-running complaints on riding mowers and tractors:
- Keep the air filter clean
- Change oil on schedule
- Use the correct spark plug and gap (per the manual)
- Store fuel properly; do not leave old fuel sitting for long periods
- Run the engine at full speed (fast) while mowing for best cutting performance

What year did Craftsman make the 917288573?
Craftsman model 917288573 (shown in the operator’s manual as 917.28857) is a later-generation Craftsman lawn tractor, not an early-1990s unit. The most accurate way to pin down the exact build year for your specific tractor is to use the serial number and product identification information in the 917288573 operator’s manual.
How to find the exact build year (fastest method)
The model number identifies the tractor family; the serial number identifies the production run and build date.
- Locate the model and serial tag (commonly under the seat, on the frame rail, or near the rear fender)
- Record the serial number exactly as printed
- Check the manual’s product identification section for where the tag is located and how it’s formatted
- Keep the serial number with your parts list for future belt, blade, and deck service
What the manual tells you about the tractor
From the operator’s manual cover, this tractor is configured as a Craftsman lawn tractor with:
- 46-inch mower deck
- Electric start
- Automatic transmission
Quick reference
| Identifier | Where you’ll see it | What it’s used for |
|---|---|---|
| Model number 917288573 | Frame tag, parts lookup | Finds correct diagrams and parts groups |
| Manual model format 917.28857 | Manual cover and pages | Same model family, different punctuation |
| Serial number | Frame tag | Determines the specific build/run details |
Why it matters
The production year and serial range affect parts compatibility for common wear items such as deck belts, blades, and spindle components. For example, deck hardware and spindle parts like the lawn tractor mandrel housing 587819701 can vary by production run.
