Craftsman 917274761 tractor Parts

For a Craftsman riding tractor like model 917274761, a full engine replacement typically costs about $800 to $2,500 installed (engine plus labor). The engine itself is usually the biggest cost; labor commonly runs 3 to 6 hours depending on how much has to be transferred from the old engine.

What drives the total price

• Engine type and horsepower (single-cylinder vs. V-twin)
• Whether the replacement is new, rebuilt, or used
• Extra parts needed (belts, pulleys, wiring, fuel line, battery)
• Shop labor rate and minimum charges
• Condition of the tractor (rusted fasteners, damaged mounts, worn PTO components)

Typical cost breakdown (what most owners see)

Cost item	Typical range	Notes
Replacement engine	$500 to $1,900	Varies widely by brand/spec and availability
Labor	$300 to $900	Often 3 to 6 hours total
Misc. parts and supplies	$25 to $200	Fuel line, clamps, oil, filter, hardware

Before you replace the engine, rule out common “no-start” causes

Many tractors that seem to need an engine actually have a starting or fuel issue. The troubleshooting chart in the 917274761 owner's manual points to checks like battery condition, wiring, ignition switch, and solenoid.

Start with these quick checks:

• Battery and terminals: clean and tighten connections
• Fuse and wiring: inspect for corrosion or broken connectors
• Ignition switch and key: worn switch or key can prevent cranking
• Starter solenoid: clicking or intermittent crank often points here
• Fuel quality: drain stale fuel; replace the fuel filter if restricted

If you’re hearing a click but the engine will not crank, follow the steps in riding lawn mower engine clicks but doesnt turn over video.

Why it matters

An engine swap is one of the highest-cost repairs on a riding mower. Confirming the problem first can save hundreds of dollars and may point to a simpler fix such as replacing the solenoid with brass plunger 532146154 or the lawn tractor ignition switch 532193350.

Yes, replacing the engine on your Craftsman 917274761 front-engine lawn tractor is worth it when the tractor’s deck, steering, and transmission are still solid and you want to extend the machine’s life; it is usually not worth it when multiple major systems are worn and the total repair cost approaches the price of a replacement tractor.

Quick decision checklist

• Deck and frame condition: no cracks, severe rust-through, or major deck damage
• Drive system health: tractor moves smoothly; no persistent slipping or loss of drive
• Steering and braking: steering is tight enough to control safely; brakes can be adjusted to work properly
• Parts availability: common wear parts are still easy to get for your model
• Total cost: engine + install parts + any “while you’re in there” repairs stay well below replacement cost

What to inspect before you commit

Use the maintenance and safety guidance in the owner's manual and do these checks with the engine off and cooled down.

• Look for excessive vibration; it can point to deck or blade issues (not just engine-related)
• Inspect blades and mandrels; bent or damaged components can mimic engine problems
• Check that nuts and bolts are tight and safety devices operate correctly
• Confirm the tractor is free of heavy grass and debris buildup around the deck and engine area

Common “not the engine” items that change the math

Symptom	Often caused by	Example part on this model page
Rough cut or vibration	Worn or bent blade, loose hardware	Lawn tractor 42-in deck high-lift blade 532138971
Poor mulching or uneven cut	Blade type mismatch, dull blade	Husqvarna lawn tractor mulching blade, 21-in 532134149
No-crank or intermittent start	Electrical switch/solenoid/key issues	Solenoid with brass plunger 532146154

Why it matters

An engine swap can be a smart investment, but only if it restores a tractor that is already mechanically sound. If the deck, drive belt system, or safety interlocks also need major work, you can end up paying for an engine and still have an unreliable mower.

Safety notes we follow during evaluation

• Never adjust or repair anything with the engine running.
• Blades are sharp; we wrap the blade or wear gloves when servicing.
• After striking an object, stop and inspect before restarting.
