Do Craftsman mowers use Briggs and Stratton engines?
Yes, many Craftsman mowers and lawn tractors use Briggs & Stratton engines, but it depends on the exact model and production run. For Craftsman lawn tractor model 917255840, the engine brand is not identified in the model-specific information we have here; the sure way to confirm is by checking the engine ID label on your tractor and the specifications in the 917255840 operator's manual.
How to confirm the engine brand on model 917255840
We recommend verifying the engine itself because Craftsman tractors can be built with engines from different manufacturers.
- Look for an engine label on the engine shroud, valve cover, or blower housing
- Record the engine model, type, and code (or spec number)
- Match that information to parts and service references for the engine manufacturer
- Use the tractor model number 917255840 when ordering chassis and deck parts
- If you are ordering engine-related parts, use the engine model/type/code from the label
What we can confirm from the 917255840 manual
The operator’s manual for Craftsman 917255840 describes this tractor as a 19.0 HP, 46-inch mower with electric start and automatic transmission, and it lists general maintenance specs (oil type, spark plug type, fuel guidance). It does not explicitly name Briggs & Stratton as the engine manufacturer in the excerpted model documentation.

What are the most common issues with 917255840?
The most common problems we see on the Craftsman 917255840 front-engine lawn tractor involve the mower deck drive (belt slip or blade engagement issues), steering looseness, and no-start electrical faults. These issues usually trace back to normal wear items like belts, pulleys, and the starter solenoid.
Common symptoms and what they usually point to
- Mower deck will not engage or cuts unevenly: worn or stretched deck belt, damaged blade, or a failing mandrel/pulley.
- Squealing or burning rubber smell: belt slipping from misrouted belt path, weak tension, or a seized idler pulley.
- Tractor will not move or drive feels weak: worn ground drive belt or idler pulley problems.
- Loose steering or poor tracking: worn drag link or pivot link components.
- Clicking but no crank: weak battery connections or a failing starter solenoid.
Parts that commonly fix these issues (when worn)
If your symptoms match, these model-compatible parts are common solutions:
| Symptom | Common wear item | Example part for 917255840 |
|---|---|---|
| Deck won’t spin blades | Deck drive belt | Husqvarna lawn tractor blade drive belt 584453101 |
| Tractor won’t drive | Ground drive belt | Lawn tractor ground drive belt 587086101 |
| Clicking, no crank | Starter circuit | Lawn tractor starter solenoid 582042802 |
| Rough cut, vibration | Blade or spindle wear | Husqvarna lawn tractor 46-in deck high-lift blade 532405380 |
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, cracking, fraying, or slack.
- Spin idler pulleys by hand; they should turn smoothly and quietly.
- Check blade condition and tightness; replace bent or heavily nicked blades.
- For no-start: verify battery terminals are clean and tight; listen for a solid solenoid click.
Why it matters
On riding mowers and tractors, worn belts and pulleys reduce blade tip speed and traction, which leads to poor cut quality and extra strain on the engine and deck components. Catching wear early helps prevent bigger repairs.
For model-specific maintenance intervals, belt routing, and adjustment procedures, use the owner's manual.
