How to find Craftsman model number?
On the Craftsman lawn tractor model 917255830, the model number is typically shown on the product identification label located on the tractor frame under the seat area (sometimes on the underside of the seat). For label location and operating details, use the 917255830 operator's manual.
Check these common label locations first:
- On the frame directly under the seat (lift the seat to view)
- On the underside of the seat pan
- Near the rear fender area close to the seat mounting points
- On the frame rail near the engine compartment (less common)
We recommend recording both numbers from the label:
- Model number (used to match parts and diagrams)
- Serial number (helps confirm production run and correct revisions)
- Any product number or manufacturing code listed
Craftsman riding mower model numbers are often printed in a few different ways. Here is what to expect:
| How it may appear on the label | What it means |
|---|---|
| 917.25583 | Same model as 917255830 |
| 917255830 | Full model number used for parts lookup |
| 917.XXXXX | Craftsman model family prefix |
Using the exact model number helps us match the correct parts for your mower deck, belts, blades, steering, and engine-related components. Even small model-number differences can change which replacement parts fit.

What brand engine does Craftsman use?
On the Craftsman lawn tractor model 917255830, Craftsman-branded tractors can be equipped with engines from multiple manufacturers; the exact engine brand on your unit is best confirmed by checking the engine ID label and the engine section of the 917255830 operator's manual.
Look for the engine manufacturer label on the engine itself. Common locations include:
- On the blower housing (top or side of the engine shroud)
- Near the spark plug wire or valve cover area
- On the engine block near the starter or muffler
- Under the hood on a decal near the engine compartment
The label typically lists the engine brand, model, type, and code/spec numbers.
Craftsman has used engines from several major small-engine makers across different tractor model years and configurations, including:
- Briggs & Stratton
- Kohler
- Kawasaki
- Other OEM suppliers depending on production run
Because Craftsman model numbers can span multiple production variations, we use the engine ID tag (not just the tractor model number) to confirm the engine manufacturer.
| What you have | Where to find it | What it tells you |
|---|---|---|
| Tractor model 917255830 | Tractor frame tag (often under seat or on frame rail) | Which tractor parts fit |
| Engine model/type/code | Engine label on the engine shroud/block | Exact engine brand and engine parts |
The engine brand and engine model numbers determine the correct tune-up parts (spark plug, air filter, oil filter) and the right service procedures. Using the engine ID prevents ordering the wrong maintenance parts.

What kind of engine does a Craftsman riding lawn mower have?
The Craftsman riding lawn mower model 917255830 uses a gasoline-powered, low-emission internal combustion engine with electric start and a 19.0 HP rating. The engine’s manufacturer and displacement aren’t identified in the model-specific information; you can confirm them from the engine ID label on the tractor.
From the 917255830 operator’s manual, these engine basics are specified:
- Fuel: regular unleaded gasoline (up to E10)
- Fuel capacity: 2.5 gallons
- Engine type: low-emission internal combustion engine
- Starting system: electric start
- Spark plug: Champion RC12YC (gap .030 in)
- Oil type: SAE 30 above 32°F, SAE 5W30 below 32°F
On model 917255830, the most reliable way is to read the engine’s ID decal (usually on the blower housing, valve cover, or near the starter).
- Look for manufacturer name (brand)
- Record the model/type/code (or similar ID numbers)
- Match those numbers when buying engine maintenance parts
- Use the manual’s maintenance schedule for service intervals
| What you’re trying to confirm | Where to check | Why it matters |
|---|---|---|
| Engine manufacturer | Engine shroud or valve cover decal | Ensures correct filters and tune-up parts |
| Engine model/type/code | Engine ID label | Needed for exact carburetor and ignition parts |
| Horsepower rating | Tractor hood decal or manual | Helps match performance specs |
“Kind of engine” often affects which air filter, oil filter, and fuel system parts fit. Confirming the engine ID first helps prevent ordering the wrong maintenance parts for your Craftsman 917255830.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman 917255830 front-engine lawn tractor can be worth it when the tractor is otherwise in good condition and the total engine job (engine plus labor) is under about 50% of the cost of a comparable replacement rider. Use the 917255830 operator’s manual to confirm symptoms and rule out simpler causes first.
A simple rule that works well for the Craftsman 917255830:
- Replace the engine when the total engine job is under 50% of the cost of a comparable replacement tractor.
- Replace the tractor when the engine job is 50% or more, especially if the deck, steering, or transmission also needs work.
| Comparable replacement tractor cost | Engine job target (50%) | Usually best choice |
|---|---|---|
| $1,000 | $500 | Replace engine if the rest is solid |
| $1,500 | $750 | Replace engine if deck and transmission are strong |
| $2,000 | $1,000 | Replace engine only if you plan to keep it long-term |
Before you price an engine, make sure the rest of the tractor is worth saving:
- Mower deck: no rust-through or cracks; spindles are not roaring or wobbling
- Transmission/drive: moves smoothly forward and reverse; no slipping or loss of drive
- Steering/front end: no severe looseness or bent linkage
- Electrical/safety: starts and runs consistently; safety interlocks behave normally
- Maintenance basics: fresh fuel, correct oil level, clean air filter
On the Craftsman 917255830, the engine can seem weak when the blades are engaged if the deck drive system is dragging or the belt is worn.
- Check belt condition and routing; replace if glazed, cracked, or stretched
- Inspect idler pulleys and mandrel pulleys for rough bearings or wobble
- Clear packed grass buildup under the deck
If you need the deck belt, use the exact replacement listed for this model: husqvarna lawn tractor blade drive belt 584453101.
An engine swap can restore years of mowing, but it will not fix a worn transmission, failing deck components, or loose steering. Using a 50% cost threshold helps you avoid investing heavily in a tractor that still will not be reliable.
