Craftsman 917273201 46" 24-hp electric start mower automatic garden tractor Parts

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.

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.

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

1. Park on level ground, set parking brake, remove key, and disconnect the spark plug wire.
2. Confirm the PTO is OFF and the operator is seated; safety interlocks must be satisfied.
3. Inspect belts for glazing, cracking, or slack.
4. Check for loose fasteners on steering and deck hardware.
5. 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.

For model-specific diagrams, adjustment points, and maintenance intervals, use the owner's manual.
