Craftsman 917276180 tractor Parts

The Craftsman riding mower model 917276180 uses a 20.0 HP engine (with a 42-inch mower deck and electric start). For the exact engine family details and operating requirements for your tractor, use the specifications and maintenance sections in the 917276180 owner's manual.

What “20.0 HP” tells you (and what to check next)

Horsepower is the headline spec, but the correct replacement parts and tune-up items depend on the engine’s exact model and type code (often found on an engine label).

• Look for the engine ID label on the engine shroud, valve cover, or blower housing
• Record the full engine model and type numbers before ordering ignition or fuel parts
• Use the correct oil type and service intervals listed for this tractor
• Keep the cooling fins and air screen clean to prevent overheating
• Follow the safety interlock and starting procedure to avoid no-start symptoms

Where to find the engine identification

Most riding mower engines have an ID tag or stamped numbers. Common locations include:

What to look for	Typical location	Why it matters
Engine model/type code	Blower housing or shroud	Ensures correct carburetor, starter, and ignition parts
Serial number	Near the model/type	Helps match production changes
Emissions label	Shroud or valve cover area	Confirms engine family and compliance info

Related parts and systems that affect starting and power

If the engine cranks slowly, clicks, or will not crank, the starting circuit is often the issue (battery, wiring, solenoid, safety switches). A common service part for this tractor is the lawn tractor starter solenoid 582042802.

Why it matters

Using the correct engine identification prevents ordering the wrong tune-up parts and helps you follow the right maintenance schedule (oil checks, blade and belt inspections, and cooling system cleaning) so your 917276180 runs reliably.

Yes, replacing the engine on your Craftsman tractor model 917276180 is worth it when the deck, transmission, and steering are solid and the total engine-swap cost stays well below the cost of a comparable new riding mower. If multiple major systems are worn, replacement makes more sense.

Quick decision checklist

• The mower deck is straight (no major rust-through or cracks)
• The transaxle drives smoothly forward and reverse (no slipping)
• The PTO and blades engage normally (no constant belt squeal)
• You can still get common wear parts like belts, blades, and pulleys
• The engine failure is isolated (thrown rod, low compression, seized) and not part of a bigger maintenance backlog

Cost and value guide (simple rule)

Use this rule to decide quickly: engine swap is a good value when the total repair is under about half the price of a comparable new tractor.

Situation	Usually the better choice	Why
Deck and drive system are in good shape	Replace the engine	You keep a solid chassis and save money
Deck is damaged or multiple systems are failing	Replace the tractor	Costs stack up fast
You mow large acreage and need reliability	Replace engine (if rest is strong)	New engine improves uptime
You rarely mow and want minimal hassle	Replace the tractor	Less DIY time and setup

What to inspect on model 917276180 before you buy an engine

We recommend checking these items first because they often determine whether an engine swap will actually solve your problem:

• Deck spindle area: listen for rumbling and check for wobble; a worn spindle housing can cause vibration and belt wear (see lawn tractor mandrel housing 587819701)
• Blade condition: bent or badly worn blades can mimic engine problems by causing heavy load and poor cut (common replacements include lawn tractor 42-in deck high-lift blade 532138971)
• Belts and idlers: worn belts slip under load and reduce performance; inspect for glazing and cracking
• Battery and starting circuit: many “bad engine” complaints are actually starting issues; the manual troubleshooting points to checking wiring, switch, solenoid, and starter (use the 917276180 owner's manual)

Why it matters

An engine swap only pays off when the tractor’s cutting system and drivetrain can take advantage of the new power. If the deck is out of level, blades are dull, or belts are slipping, you can spend engine money and still get poor mowing results.

For a Craftsman riding tractor like model 917276180, a full engine replacement (parts plus labor) typically runs about $260 to $1,800 installed, with labor time commonly around 6 hours depending on the shop rate and any extra repairs found during teardown.

What drives the total cost

Engine replacement cost varies mostly by engine type, labor rate, and whether related wear items get replaced at the same time.

• Engine price: new, rebuilt, or used engine options
• Labor rate: local shop hourly rate and minimum charges
• Extra parts: belts, pulleys, wiring, fuel filter, battery, hardware
• Condition issues: stripped mounting bolts, damaged wiring, worn PTO or deck components
• Setup/tune: throttle/choke linkage adjustment, charging system check, test run

Typical cost breakdown (installed)

Cost item	Typical range	Notes
Engine (part)	$200 to $1,400	Biggest variable by brand and horsepower class
Labor	$200 to $600	Often 4 to 8 hours total time
Fluids and small parts	$20 to $150	Oil, filter, clamps, fuel line, fasteners
Optional related repairs	$0 to $500+	Belts, pulleys, battery, wiring fixes

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

Many tractors get labeled “needs an engine” when the issue is electrical, fuel, or safety interlocks. Your 917276180 manual troubleshooting steps include basics like depressing the brake, disengaging the attachment clutch, checking wiring, and checking the solenoid/starter.

• Recharge or replace the battery; clean terminals
• Check the fuse and wiring connections
• Test the starter solenoid and starter
• Replace a dirty fuel filter and drain stale fuel
• Check spark plug condition and plug wire fit

If you suspect a starting circuit issue, the riding lawn mower engine clicks but doesnt turn over video is a good quick diagnostic walkthrough.

Parts that commonly get replaced during engine service

Even if the engine is the main job, we often see these items addressed at the same time to prevent repeat downtime:

• Lawn tractor starter solenoid 582042802 (no-crank or intermittent crank)
• Husqvarna lawn tractor belt, 1/2 x 101-1/6-in 592855001 (worn or glazed belt)
• Fuel filter, spark plug, air filter, engine oil and filter (if equipped)

Why it matters

An engine swap is one of the highest-cost repairs on a riding mower. Confirming the real failure first can save hundreds of dollars and get your Craftsman 917276180 back to mowing faster.

For maintenance intervals and safety steps (shut off engine, remove key, wait for moving parts to stop), use the 917276180 owner's manual.
