Craftsman 917271815 lawn tractor Parts

For a Craftsman lawn tractor like model 917271815, a full engine replacement typically costs about $800 to $2,500 total (engine plus labor). The biggest cost drivers are the exact engine type, whether the replacement is new or rebuilt, and the shop labor time.

Typical cost breakdown

• Engine (new): $500 to $1,800
• Engine (rebuilt/used): $250 to $900
• Labor: $300 to $900 (often 4 to 8 labor hours)
• Extra parts/fluids: $25 to $150 (oil, filter, fuel filter, clamps, hardware)

What you replace	Typical parts cost	Typical labor cost	Best when
Full engine	$500 to $1,800	$300 to $900	Engine has low compression, rod knock, or major internal damage
Tune-up and fuel service	$25 to $200	$100 to $300	Engine cranks but runs poorly or will not start
Electrical start repair	$10 to $250	$75 to $250	Engine clicks or will not turn over

Before you replace the engine (save money first)

Many “needs an engine” symptoms are caused by fuel, ignition, or safety interlock issues. We use these quick checks first:

• Confirm the clutch/brake pedal is fully depressed and the attachment clutch is disengaged (the tractor should not start otherwise).
• Check the operator presence and interlock system; the engine should shut off if you leave the seat without setting the parking brake.
• Inspect fuel quality; drain stale fuel and refill with fresh gasoline.
• Check the spark plug wire connection and basic ignition condition.
• Clean or replace the air filter and clear debris from engine cooling fins.

For the exact starting and safety-interlock behavior for this tractor, follow the 917271815 owner's manual.

Why it matters

Engine replacement is one of the highest-cost repairs on a riding mower. A correct diagnosis prevents spending $1,000+ when a tune-up, wiring fix, or interlock adjustment restores normal starting and running.

For a Craftsman riding mower like model 917271815, we look up the correct model number by finding the model and serial tag on the tractor, then matching that exact number when ordering parts or checking diagrams. On most Craftsman lawn tractors, the tag is on the frame under the seat or on the underside of the seat.

Where to find the model and serial number tag

Check these common locations first:

• On the frame under the seat (lift the seat and look down at the frame rails)
• On the underside of the seat pan
• Near the rear fender area close to the seat mounting points
• On a sticker or metal plate that lists both model and serial numbers

For model 917271815, the owner documentation identifies it as “Model No. 917.271815” (the dot is often omitted on the tag), so 917271815 is the number to use for parts lookup. See the 917271815 owner's manual for model identification and parts information.

How to use the number once you find it

Use the model number exactly as shown on the tag to ensure the right parts fit.

• Enter the full model number (example: 917271815) when searching parts
• Use the model to match the correct mower deck size, drive system, and diagrams
• Keep the serial number for service history and production variations

Quick check: model vs. serial

What you found	What it’s used for	Example
Model number	Parts diagrams, correct replacement parts	917271815
Serial number	Manufacturing run info, service reference	Varies by unit

Why it matters

Craftsman tractors can look similar across years, but belts, blades, mandrel assemblies, and decals can differ by model. Using the exact model number prevents ordering the wrong deck parts or drive components.

On many Craftsman riding mowers and lawn tractors, the serial number is a date code: the first 2 digits are the month, the next 2 digits are the day, and the last 2 digits are the year. For Craftsman model 917271815, confirm the exact serial tag format in the 917271815 owner's manual.

How to decode the 6-digit date-style serial number

If your serial number is MMDDYY, read it like this:

• MM = month (01 to 12)
• DD = day (01 to 31)
• YY = year (00 to 99)
• Example: 072811 = July 28, 2011
• Write the date down before ordering parts or scheduling service

Where to find the serial number on a riding lawn tractor

Most Craftsman lawn tractors place the serial/model tag in a spot that stays readable but protected.

• Under the seat pan or on the seat deck
• On the rear fender area near the seat
• On the frame rail (left or right side)
• Near the engine compartment or hood opening
• On a sticker or metal plate with the model number

Why it matters (parts and service accuracy)

Craftsman tractors can have production changes within the same model family. Using the serial number date helps match the correct diagrams and parts, especially for wear items like blades, belts, and ignition components.

What you’re doing	What to use	Why it helps
Ordering replacement parts	Model number + serial/date code	Prevents mismatched parts
Troubleshooting starting issues	Serial/date code + wiring diagram	Helps identify correct electrical layout
Replacing a lost key	Key style and ignition listing	Ensures the key fits the switch

Yes, replacing the engine on your Craftsman lawn tractor model 917271815 is worth it when the tractor’s deck, steering, and chassis are solid and the total engine swap cost stays well below the cost of a comparable new rider. If the tractor has multiple worn systems, replacement makes more sense.

Quick decision checklist

• The mower deck is straight, not rusted through, and still cuts evenly after leveling
• The transaxle drives smoothly (no slipping, whining, or loss of power under load)
• Steering and front axle are tight enough to track straight
• You can do the work safely (or have a shop install the engine)
• The engine replacement cost is under about half the price of a comparable new riding mower

Cost and effort: what to compare

Engine swaps are usually most successful when you treat them like a full refresh, not just a single part change.

Option	Best when	What you gain	What to watch for
Replace engine	Tractor is in good overall condition	Fresh reliability and typically a warranty	Upfront cost, installation time
Rebuild/short block	You want to save money and keep original setup	Lower parts cost than a full engine	More labor, more downtime
Replace tractor	Multiple major systems are worn	New machine, less project time	Higher total spend

Related wear items to inspect while deciding

These items often determine whether the tractor is “worth it” because they affect cut quality and drivability.

• Deck drive belt condition and routing (a worn belt can mimic power problems)
• Blade and mandrel condition; a noisy spindle points to deck wear
• Blade hardware torque and correct blade installation (the manual calls out 27-35 ft-lbs on the blade bolt)
• Deck buildup and vent holes around mandrels; packed grass can cause poor cutting and overheating
• Safety interlock operation (seat switch, clutch/brake start interlock, PTO engagement rules)

If you’re already replacing deck components, pricing a known-fit blade like the husqvarna lawn tractor mulching blade, 21-in 532134149 can help you estimate the “all-in” refresh cost.

Why it matters

A new engine will not fix problems caused by deck airflow restrictions, dull blades, worn belts, or failing safety interlocks. Confirming those basics first prevents spending engine money on a tractor that still will not cut or run correctly.

For operating and service safety steps (including blade handling and interlock checks), follow the 917271815 owner's manual.

Craftsman lawn tractors use engines sourced from multiple manufacturers, depending on the specific tractor and production year. For Craftsman model 917271815, our 917271815 owner's manual confirms it has a low-emission engine, but it does not identify the engine brand in the excerpted specifications.

How to identify the engine brand on model 917271815

Use the engine’s ID plate, not the tractor model number. On most front-engine riding mowers, the engine label is on the blower housing, valve cover area, or near the starter.

• Look for an engine model and type/spec number (often on a sticker or stamped tag)
• Record the full engine model exactly as shown
• Match that engine model to the correct tune-up parts (spark plug, air filter, oil filter)
• If the label is missing, check for casting marks and the carburetor style as clues
• Use the tractor’s parts diagrams to confirm related items like belts and deck hardware

Common engine brands used on Craftsman lawn tractors

Across Craftsman riding mowers, the most common engine suppliers are:

Engine brand	What you’ll typically see on the label	Notes
Briggs & Stratton	“Briggs & Stratton” plus model/type/code	Very common on many Craftsman tractors
Kohler	“Kohler” plus model/spec	Common on some mid to higher HP tractors
Kawasaki	“Kawasaki” plus model/spec	Often found on select premium models

Why it matters

The engine brand determines the correct maintenance parts and service specs (oil type, spark plug, air filter, valve clearance). Using the engine model from the ID plate prevents ordering the wrong parts even when the tractor model is correct.

Related parts you may replace during maintenance

If you are doing a seasonal service on the mower deck or drive system, these model-matched parts are commonly replaced:
