How to look up Craftsman model number?
To look up the correct Craftsman model number for parts and manuals, we use the model and serial tag on your tractor. On Craftsman model 917276901, you will typically find it on the frame under the seat or on the underside of the seat; match that number exactly when searching.
Where to find the model and serial number
Check these common locations on a Craftsman front-engine lawn tractor:
- Frame rail under the seat (look for a sticker or metal tag)
- Underside of the seat pan
- Rear fender area near the seat mounting points
- Near the engine compartment on the frame (less common)
- On the mower deck shell (occasionally, but the frame tag is the best reference)
For diagrams and the exact identification details used for this tractor family, use the 917276901 owner's manual.
How to use the number once you find it
Use the model number to pull the right parts list, diagrams, and maintenance specs.
- Enter the model number exactly as printed (no spaces, no extra characters)
- Use the serial number to confirm production variation when ordering parts
- If the tag is worn, clean it gently and use a flashlight at an angle to read embossed text
Quick check: model number vs. serial number
| Item | What it does | Example format |
|---|---|---|
| Model number | Identifies the tractor design and parts breakdown | 917.276901 or 917276901 |
| Serial number | Identifies the specific unit and build run | Varies by unit |
Why it matters
Craftsman tractors often have similar-looking frames and decks, but parts like the PTO switch, starter solenoid, and deck components can vary by model and serial range. Using the exact model number helps ensure the right fit the first time.

Is it worth replacing a lawn mower engine?
Yes; replacing the engine on your Craftsman front-engine lawn tractor model 917276901 is worth it when the deck, chassis, steering, and drive system are still in good condition and the total swap cost stays well below the cost of a comparable new tractor. If multiple major systems are worn out, replacement makes more sense.
Quick decision checklist
- Deck and chassis are solid (no cracks, severe rust-through, or bent structure)
- Tractor drives and steers safely (no slipping drive, excessive play, or brake issues)
- Engine problem is truly internal (low compression, knocking, seized)
- You want to keep your current attachments and setup
- You can handle the labor, tools, and safe lifting needed for an engine swap
Cost and effort: compare your options
| Option | Typical cost | Effort | Best when |
|---|---|---|---|
| Fix the existing engine | Low to medium | Medium | Fuel, spark, wiring, starter, or safety-interlock issue |
| Replace with a short block | Medium | High | Bottom-end failure but external parts are reusable |
| Replace the complete engine | Medium to high | Medium | Fastest, cleanest reset |
| Replace the tractor | High | Low | Deck, transmission, steering, and engine all show heavy wear |
Rule of thumb we use
If the engine swap total is more than about 50% of the price of a comparable new riding mower, replacing the tractor is usually the better value. Under that, a solid chassis and deck make an engine swap a smart investment.
Rule out common “bad engine” symptoms first
Many no-start complaints are electrical or interlock related. Check:
- Battery condition and cable connections
- PTO disengaged and brake/clutch interlocks working (operating steps are in the 917276901 owner’s manual)
- Starter circuit and solenoid function (clicking with no crank often points here; see lawn tractor starter solenoid 582042802)
Why it matters
An engine swap can extend the life of a good Craftsman tractor for years, but only if the rest of the machine is safe and mechanically sound.

What year is a Craftsman 917276901 riding mower?
The Craftsman riding mower model 917276901 does not have a single “model year” printed in the operator’s manual; the exact build date is typically identified from the product ID/serial label on the tractor (commonly under the seat or near the frame). Use the 917276901 owner's manual to confirm the correct label location and identification details.
How to find the exact year on your tractor
We recommend using the tractor’s serial or product ID information (not just the model number) because the same model series can be produced across multiple years.
- Look for a product ID/serial number label under the seat, on the frame rail, or near the rear fender area
- Write down the model number (917276901) and the serial/product ID exactly as shown
- Check for a date code or manufacturing code printed on the label
- If the label is dirty or faded, clean it gently and take a clear photo for reference
- Match the tractor’s configuration to the manual cover details (engine HP, deck size, transmission type)
What the manual tells us about this model family
The operator’s manual cover shows this tractor family as a 26.0 HP, 54-inch mower, electric start, automatic transmission, and it lists model numbers 917.276900 / 276901. That confirms you have the correct manual family, but the manual itself is not a “year identifier.”
| Identifier | What it tells you | Where to find it |
|---|---|---|
| Model number (917276901) | Parts and manual match | Tractor label, paperwork |
| Serial/product ID | Build date and production run | Tractor label |
| Engine model/type code | Engine build info | Engine shroud/label |
Why it matters
The year (and production run) affects parts fitment for items like the PTO switch, starter solenoid, deck components, and wiring. Using the serial/product ID helps us match the correct diagrams and replacement parts the first time.
