Craftsman 917271635 lawn tractor Parts

For a Craftsman riding lawn tractor like model 917271635, a full engine replacement typically runs about $800 to $2,500 installed (engine plus labor). The total depends on engine type, whether the replacement is a direct-fit, and how much related hardware (belts, pulleys, wiring) needs attention.

What drives the total cost

• Engine price: Most riding mower engines commonly fall in the $500 to $1,800 range.
• Labor time: A typical shop job is 4 to 8 hours for removal, swap, and setup.
• Extra parts: You may need a new drive belt, fuel line, battery cables, or mounting hardware.
• Deck and PTO condition: Worn pulleys, mandrels, or blade hardware can add time and cost.
• Diagnosis vs. replacement: Many “dead engine” symptoms are actually electrical or fuel related.

Quick cost breakdown (typical ranges)

Cost item	Typical range	Notes
Replacement engine	$500 to $1,800	Varies by horsepower and crankshaft specs
Labor	$300 to $900	Based on 4 to 8 hours shop time
Misc. parts/fluids	$25 to $200	Oil, filter, clamps, hardware
Estimated total	$800 to $2,500	Most common real-world range

Before you replace the engine (save money first)

We recommend checking these common no-start causes first because they can mimic a failed engine:

• Battery charge and cable connections
• Starter solenoid operation (a click with no crank is common)
• Safety interlock switches (seat, brake, PTO)
• Fuel quality and carburetor condition
• Compression and spark (basic engine health)

For model-specific safety interlock behavior and starting conditions, use the owner's manual.

Helpful parts that often come up during engine or starting repairs

If the tractor clicks or has intermittent cranking, a starter solenoid is a frequent fix:

• Solenoid with brass plunger 532146154

If you are also servicing the mower deck while the tractor is down, blade and mandrel wear are common:

• Husqvarna lawn tractor mulching blade, 21-in 532134149
• Husqvarna lawn tractor mandrel assembly 532130794

Why it matters

An engine swap is one of the highest-cost repairs on a riding mower. Confirming the starting system, safety interlocks, and deck load issues first helps you avoid replacing a good engine and keeps your Craftsman 917271635 reliable for the long term.

The Craftsman riding mower model 917271635 uses a 16.5 HP low-emission engine (as specified for this tractor in the 917271635 owner's manual).

How to confirm the exact engine on your tractor

Even within the same mower family, the most reliable way to confirm the engine make and model is to match the tractor and engine ID labels.

• Check the engine shroud or valve cover area for the engine brand badge (commonly Briggs & Stratton, Kohler, or similar)
• Locate the engine ID tag (often near the starter, blower housing, or valve cover)
• Record the engine model, type, and code/spec numbers from the tag
• Compare those numbers to the engine section and parts list in the 917271635 owner's manual
• Use the engine ID numbers when ordering tune-up parts (spark plug, air filter, oil filter)

What we know for model 917271635 (from the manual)

The owner’s manual for this specific Craftsman lawn tractor identifies the tractor as:

Spec item	Model 917271635 (manual)
Engine output	16.5 HP
Starting system	Electric start
Mower deck size	42-inch
Transmission	6-speed transaxle

Why it matters

The engine brand and exact engine model determine the correct maintenance parts and settings (spark plug type and gap, air filter style, oil capacity, and governor settings). Using the tractor model alone can be enough for many chassis and deck parts, but engine service parts often require the engine ID.

Craftsman model 917271635 is a specific lawn tractor model number, but the exact build year is determined by the tractor’s serial number/date code, not the model number alone. Use the identification label on your tractor and the decoding steps in the 917271635 owner's manual to pinpoint the manufacturing date.

How to find the build date on your tractor

Most Craftsman 917-series tractors have an ID label under the seat or on the rear fender pan area. Look for a serial number and any date code printed on that label.

• Park on a level surface, set the parking brake, and remove the key.
• Lift the seat and locate the product/serial label.
• Write down the model number (917271635) and the serial number exactly as shown.
• Look for a date code on the label (often formatted as numbers that indicate month/day/year).
• Match what you find to the identification information in the 917271635 owner's manual.

What “917” means (and what it does not)

The 917 prefix is commonly associated with Craftsman riding mowers and lawn tractors built for Sears, but it does not identify a single production year by itself. The same model family can span multiple seasons with running changes.

Quick guide

What you have	What it tells you	What it does not tell you
Model number: 917271635	The exact configuration family for parts lookup	The exact year it was built
Serial number/date code	The manufacturing date or date range	Nothing about optional attachments

Why it matters

The build year affects parts details such as deck components, steering hardware, and chassis pieces. For example, parts like the lawn tractor chassis 579841401 and lawn tractor grille with lens assembly 532178987 can vary by production run, so confirming the serial/date code helps ensure the right match.
