Do Craftsman mowers use Briggs and Stratton engines?
Yes, some Craftsman mowers use Briggs and Stratton engines, but it depends on the specific model and engine originally installed. For Craftsman model 917273201 (24.0 HP, 46-inch deck), the correct engine identification is listed in the 917273201 owner's manual and on the engine label itself.
How to tell what engine your Craftsman 917273201 has
Use these quick checks to confirm the engine brand and model without guessing:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (common on Briggs and Stratton engines)
- Compare that information to the engine section in the 917273201 owner's manual
- Check for signs of an engine swap (non-original mounting, wiring changes, different muffler)
- If you are ordering ignition or PTO electrical parts, match by tractor model and wiring layout
What varies by Craftsman mower type
Craftsman used multiple engine suppliers across different mower lines and years. Here is what typically changes:
| Craftsman equipment type | Common engine brands used | What to verify before buying parts |
|---|---|---|
| Push mower | Briggs and Stratton, Honda, others | Engine model and carburetor/air filter style |
| Riding mower or garden tractor | Briggs and Stratton, Kohler, others | Engine model plus tractor model wiring and PTO setup |
| Zero-turn mower | Varies widely by series | Engine model and frame-specific mounting |
Why it matters
Engine brand affects tune-up parts (spark plug, air filter, fuel filter) and some safety and charging components. Tractor model affects chassis and deck parts like belts, mandrels, and PTO controls.
If your mower deck will not engage or the blades will not rotate, the PTO circuit and switch are common checks; the switch.pto.3 582107601 is one of the model-matched parts used for PTO engagement on this tractor.

How much does it cost to replace a riding lawn mower engine?
For the Craftsman 917273201 front-engine lawn tractor, replacing the engine is a major repair; the installed total is usually driven by the engine price plus several hours of labor. Most riding mower engine swaps land in the high hundreds to a few thousand dollars installed, depending on the exact engine and shop rate.
Typical cost ranges (installed)
These ranges reflect common riding mower engine replacement pricing (parts plus labor) and help you budget before you request a quote.
| Cost item | Typical range | What changes it most |
|---|---|---|
| Replacement engine | $500 to $2,500 | Brand, horsepower, crankshaft size, charging system |
| Labor | $300 to $1,200 | Shop rate, rusted fasteners, pulley and belt transfer |
| Fluids and tune-up items | $30 to $200 | Oil, filter, spark plug, fuel filter |
| Misc. parts and hardware | $20 to $250 | Fuel line, clamps, wiring repairs, belts as needed |
What you should confirm before buying an engine
Many “bad engine” symptoms are caused by fuel, ignition, or safety interlocks. The 917273201 uses operator-presence and interlock switches that can prevent starting or shut the engine off.
- Verify the PTO/attachment clutch is disengaged
- Fully depress the clutch/brake pedal when starting
- Check for fresh gasoline (water or old fuel causes hard starting)
- Service the air filter and cooling fins
- Inspect wiring connections for looseness or damage
- Replace a clogged in-line fuel filter (seasonal maintenance)
For the exact interlock behavior and maintenance schedule, follow the 917273201 owner's manual.
Getting an accurate quote (what to ask the shop)
- Confirm the replacement engine’s crankshaft diameter, length, and keyway match
- Ask whether they will transfer pulleys, wiring harness connections, and throttle/choke controls
- Request an itemized estimate (engine, labor hours, shop supplies, pickup/delivery)
Why it matters
An engine swap can cost more than other common repairs (belts, fuel system service, ignition parts). Verifying interlocks and basic maintenance first helps you avoid paying for an engine when a lower-cost fix restores reliable starting and power.

What are the most common issues with 917273201?
On the Craftsman 917273201 46-inch 24-HP electric-start automatic garden tractor, the most common issues are no-start or intermittent starting, blades not engaging, poor cutting (uneven cut or vibration), and drive problems such as slipping or no movement. Many of these trace to belts, switches, steering wear parts, or fuel delivery.
Common symptoms and what usually causes them
- Engine will not crank: worn key switch/key, safety interlock switch not closing, loose wiring, weak battery connections
- Engine cranks but will not start: stale fuel, restricted fuel flow, plugged venting, fuel tank or stem issues
- Blades will not engage: PTO switch failure, clutch wear, deck belt worn or off
- Poor cut quality or vibration: worn deck drive belt, mandrel/spindle wear, debris buildup under deck
- Tractor will not move or slips: ground drive belt worn, idler/pulley issues, linkage adjustment needed
- Loose steering or wandering: tie rod/drag link wear, sector gear wear, steering shaft play
Quick checks we recommend first
- Park on level ground, set parking brake, remove key, and disconnect the spark plug wire.
- Confirm the PTO is OFF and the operator is seated; safety interlocks must be satisfied.
- Inspect belts for glazing, cracking, or slack.
- Check for loose fasteners on steering and deck hardware.
- Look for fuel leaks or a collapsed fuel line; confirm the tank cap vent is clear.
Parts that commonly fix these problems (when symptoms match)
| Symptom | Likely part area | Example part for this model |
|---|---|---|
| Blades do not engage | PTO control or clutch | Switch.pto.3 582107601, clutch 532174509 |
| Deck stops or squeals | Deck belt/mandrels | Riding lawn mower blade drive belt 532148763, lawn tractor mandrel assembly 532143651 |
| No drive or slipping | Ground drive belt | Lawn tractor ground drive belt, 1/2 x 84-1/2-in 532140218 |
| Steering play | Linkage components | Tie rod 532186799, drag link 532175572 |
Why it matters
Catching belt wear, interlock switch problems, and steering looseness early prevents bigger failures like damaged pulleys, mandrel housings, or unsafe handling while mowing.
