Craftsman 917270710 lawn tractor Parts

For a Craftsman lawn tractor model 917270710, a full engine replacement typically runs $800 to $2,500 installed (engine plus labor). The total depends on the exact engine spec, whether you replace related wear items, and local shop labor rates; confirm your engine details in the 917270710 owner's manual.

What drives the total cost

• Engine type and horsepower (exact replacement vs. repower kit)
• Labor time (removal, wiring, throttle/choke setup, belt and pulley alignment)
• Extra parts often replaced at the same time (belts, pulleys, hardware)
• Shop fees (pickup/delivery, disposal, diagnostics)
• Condition of the tractor (rusted fasteners, damaged wiring, worn deck spindles)

Typical price breakdown (installed)

Cost item	Typical range	Notes
Replacement engine	$500 to $1,900	Biggest variable; exact match costs more
Labor	$300 to $900	Commonly 3 to 6 hours depending on complexity
Misc. parts and supplies	$25 to $200	Fuel line, clamps, oil, filter, hardware
Total installed	$800 to $2,500	Most common real-world range

When replacement makes sense vs. repair

Engine replacement is usually the right call when the engine has low compression, severe internal noise, thrown rod, or repeated overheating damage. If the engine still cranks and runs poorly, a tune-up and fuel system service can be far cheaper.

Quick checks that can save money first

• Verify the engine is not overheating from clogged cooling fins (cleaning is routine maintenance)
• Replace the spark plug if it is due (often every 100 hours/season)
• Replace a clogged in-line fuel filter if fuel flow is restricted
• Confirm safety interlocks and starting circuit basics before condemning the engine

Why it matters

An engine swap is one of the highest-cost repairs on a riding mower. Pricing it correctly up front helps you decide whether to invest in the tractor, or put that money toward a newer machine with a warranty and updated features.

On the Craftsman lawn tractor model 917270710, we find the model number and serial number on the tractor’s frame under the seat area; on many units it’s also printed on the underside of the seat itself. Use that exact model number to match the correct parts list and owner's manual.

Where to check on the tractor

Look in these common spots first:

• Frame under the seat (most common location)
• Underside of the seat pan
• Rear frame area near the hitch plate (sometimes)
• Fender or frame rail near the battery tray (sometimes)

How to record it correctly

Write the information exactly as shown on the tag so parts and diagrams match.

• Copy every digit and punctuation (for example, 917.270710 vs 917270710)
• Record the serial number too; it helps confirm production variations
• If the tag is dirty, wipe it with a damp rag and mild cleaner (avoid soaking the label)
• Take a clear photo before the label fades further

Why it matters

Craftsman tractors often share similar looks across years, but belts, blades, and deck parts can differ by model series. Using the correct model number helps us match the right diagrams and parts the first time.

Quick examples (what you might see)

What you see on the tag	What it means	What to do
917.270710	Model number format with a dot	Use it to look up parts and specs

Craftsman uses engines from several manufacturers across its lawn tractor lineup. For Craftsman model 917270710, the tractor is equipped with a Briggs & Stratton engine; use the engine’s model and type numbers (on the engine shroud) to match the correct tune-up parts and service specs in the 917270710 owner's manual.

How to confirm the engine brand and exact engine model

Even when the brand is known, the engine model and type numbers are what ensure you get the right air filter, spark plug, and carburetor parts.

• Park on level ground, set the parking brake, and remove the key.
• Let the engine cool completely.
• Lift the hood and locate the engine ID label on the blower housing or valve cover.
• Write down the engine model, type, and code.
• Use those numbers when ordering engine-specific maintenance parts.

Common Craftsman engine brands you may see

Craftsman tractors and riding mowers commonly use these engine brands depending on model and year.

Brand	Where you’ll see it most often	What to use for parts matching
Briggs & Stratton	Many Craftsman lawn tractors	Engine model and type numbers
Kohler	Some mid to higher HP tractors	Spec number and serial
Kawasaki	Some premium models	Model and spec code

Why it matters

Ordering by tractor model alone can lead to the wrong ignition or fuel-system parts. Matching parts to the engine ID prevents hard starting, poor performance, and repeat repairs.

For the Craftsman 917270710 front-engine lawn tractor, use SAE 30 4-cycle engine oil when temperatures are above 32°F and SAE 5W-30 when temperatures are below 32°F. Fill to the dipstick full mark; the 917270710 owner's manual lists an oil capacity of 3.0 pints.

Recommended oil by temperature

Match viscosity to the season for easier starting and better protection:

• Above 32°F: SAE 30 (API SF/SG/SH)
• Below 32°F: SAE 5W-30 (API SF/SG/SH)
• Use 4-cycle engine oil (not 2-cycle mix)
• Check oil level before each use, especially during hot-weather mowing

How to fill and check oil correctly

Use this routine to avoid overfilling and oil-related smoking:

• Park on level ground and shut the engine off
• Let the engine cool a few minutes
• Remove dipstick, wipe clean, reinstall fully, then recheck
• Add oil in small amounts and recheck often
• Stop at the FULL mark; do not fill above it

Specs at a glance

Item	Craftsman 917270710 specification
Oil type above 32°F	SAE 30 (API SF/SG/SH)
Oil type below 32°F	SAE 5W-30 (API SF/SG/SH)
Oil capacity	3.0 pints

Why it matters

Using the correct viscosity helps the engine lubricate properly as temperatures change. Filling to the correct level prevents hard starting, smoking, and power loss caused by low oil or overfilled crankcase.

On the Craftsman lawn tractor model 917270710, a no-start is usually caused by a weak battery or bad cable connection, a blown fuse, a safety interlock not being satisfied (seat, brake, PTO), or an ignition/starting component issue such as the solenoid, starter, or ignition switch. Use the 917270710 owner's manual troubleshooting chart to narrow it down fast.

Quick checks we recommend first

• Make sure the clutch/brake pedal is fully depressed.
• Make sure the attachment clutch (PTO) is disengaged.
• Check the battery charge; recharge or replace if weak.
• Clean and tighten battery terminals and cable ends.
• Check the fuse and inspect wiring for loose or damaged connections.

What the symptom tells you

What you hear/see	Most likely causes	What to do next
Engine clicks but will not start	Weak battery, dirty terminals, loose/damaged wiring, faulty solenoid or starter	Charge battery, clean terminals, then test solenoid/starter
Engine cranks but won’t start	Stale fuel, dirty air filter, fouled spark plug, fuel delivery issue	Replace fuel, service air filter, inspect spark plug
Starts then dies when you release the brake	Safety interlock circuit issue	Check seat/brake switch operation

Common causes (and the fix)

• Battery or connections: A low battery or corroded terminals can cause clicking or slow cranking; clean terminals and recharge/replace the battery.
• Blown fuse or wiring problem: A blown fuse or loose/damaged wiring can stop power from reaching the starter circuit.
• Faulty solenoid or starter: If the battery is good but it only clicks, the solenoid or starter is a top suspect.
• Ignition switch issue: A worn ignition switch can prevent the start circuit from energizing.
• Fuel and tune-up items: Old gas, a dirty air filter, or a bad spark plug can prevent starting even when it cranks.

Why it matters

Starting problems on a riding mower are often electrical and safety-interlock related. Checking the brake/PTO position and battery condition first prevents unnecessary parts replacement and gets you to the real failure point faster.

Craftsman model 917270710 is a specific lawn tractor configuration, but Craftsman model numbers do not map to one single “model year” the way cars do. The most accurate way to identify the year for your exact tractor is to use the identification information and documentation in the 917270710 owner's manual.

How to pinpoint the year for your exact 917270710

We use these checks because Craftsman tractors were often sold across multiple seasons with small running changes.

• Locate the model and serial number label (commonly under the seat, on the frame, or near the rear fender pan).
• Write down the serial number exactly as shown (letters and numbers).
• Compare the tractor’s configuration to the manual specs (engine HP, deck size, transmission type).
• Check for date codes on major components (engine tag, battery sticker, or wiring harness label).
• If the tractor has had major parts replaced (engine, transaxle, deck), rely on the frame serial number, not the replacement part.

What the manual tells us about this tractor (helps confirm you have the right model)

The documentation for 917270710 identifies it as a 17.0 HP, electric start, 42-inch mower, 6-speed transaxle lawn tractor. That combination helps confirm you are matching the correct manual and parts list to your machine.

Item in documentation	What to look for on your tractor	Why it helps
42-inch mower deck	Deck width and blade setup	Confirms deck family and parts fit
6-speed transaxle	Shift pattern and lever	Separates gear-drive from hydro models
Electric start	Key switch start	Confirms electrical starting system

Why it matters

Getting the correct “year” is mainly about getting the correct parts and adjustments. Even within the same model number family, belt routing, deck hardware, and steering components can vary by production run.

If you are ordering wear items for this tractor, match by model number and diagrams first; for example, the ground drive belt v-belt 532138255 is a common fitment-sensitive part where length and routing must match your exact setup.
