For a Craftsman riding mower like model 917271042, we look up the model number by finding the model and serial tag on the tractor itself, then using that exact number when searching parts and diagrams. On most Craftsman tractors, the tag is on the frame under the seat or on the underside of the seat.

Where to find the model and serial tag

Check these common locations first:

• On the frame directly under the seat (lift the seat and look on the chassis rails)
• On the underside of the seat pan
• Near the rear fender area close to the seat hinge (sometimes adjacent to the frame tag)
• On a sticker or metal plate with both model and serial information

How to use the number once you find it

Use the model number exactly as printed (including all digits).

• Enter the full model number (example: 917271042) in the model search
• Match the product type (front-engine lawn tractor) to avoid similar results
• Use the parts diagrams to confirm fit before ordering belts, blades, or steering parts

Quick checklist: what to write down

• Model number
• Serial number
• Any additional product number on the same tag

Common mistakes that cause the wrong parts lookup

• Mixing up the serial number with the model number
• Dropping digits (for example, searching 91727104 instead of 917271042)
• Using a number from the engine label instead of the tractor frame tag

Why it matters

Craftsman tractors often share similar frames and decks across multiple model numbers. Using the exact model number ensures we show the correct parts list for items like the ground drive belt, blade drive belt, and deck components.

What you find	What it’s used for	Example
Model number	Parts lookup and diagrams	917271042
Serial number	Production identification	Varies

A “42-inch” riding lawn mower refers to the cutting deck width, not the tractor’s overall width. For Craftsman model 917271042, most 42-inch deck tractors measure about 48 to 52 inches wide overall (outside tire to outside tire), depending on tire size and deck configuration.

What “42-inch” actually means

The 42 inches is the approximate swath the blades cut in one pass.

• Deck width (cutting width): 42 inches
• Overall width: typically wider than the deck
• Why wider: rear tires, deck shell overhang, and discharge chute area

Typical width ranges you can expect

Because we do not have model-specific dimension documentation for 917271042 on this parts page, we use common 42-inch lawn tractor sizing to guide you.

Measurement you care about	Typical size for a 42-in deck tractor	What to measure on your tractor
Cutting width	42 in	Blade path under the deck
Overall width (mowing setup)	48 to 52 in	Outside of left tire to outside of right tire
Clearance width to fit through a gate	52 to 60 in	Add a safety margin for steering and uneven ground

How to measure your mower width accurately

Use a tape measure with the tractor on level ground.

• Measure outside edge of left rear tire to outside edge of right rear tire
• If the discharge chute sticks out, measure to the widest point on that side
• Measure with the deck set to a normal mowing height
• If you are fitting a shed or trailer, add 2 to 4 inches of clearance

Why it matters

Overall width determines whether your Craftsman riding mower fits through gates, onto a trailer ramp, and into storage. The deck size alone does not guarantee clearance.

Related parts that can affect “overall width”

Tire size and wheel setup can change the outside-to-outside measurement. If you are replacing wheels or tires, match what your tractor uses.

A Craftsman front-engine lawn tractor such as model 917271042 uses a small gasoline engine made up of fuel, air, ignition, and internal rotating parts that work together to create power. The exact layout varies by engine family, but the core components are consistent across most riding mowers.

Main lawn tractor engine parts (and what they do)

• Fuel tank: stores gasoline and feeds the fuel line
• Carburetor (or fuel injection on some models): mixes fuel and air for combustion
• Air filter: keeps dirt out of the intake so the engine can breathe clean air
• Ignition system: typically the ignition coil and spark plug that ignite the fuel-air mix
• Starter system: starter motor, solenoid, battery, and key switch that crank the engine
• Flywheel: helps smooth engine rotation; often includes magnets for charging/ignition timing
• Crankshaft and connecting rod: convert piston movement into rotating power
• Crankcase: houses internal components and holds engine oil
• Muffler: reduces exhaust noise and directs hot exhaust away

Quick “system view” of how the engine works

System	Key parts	Common symptom when it fails
Fuel	tank, fuel line, carburetor	cranks but will not start, surging
Air	air filter, intake	black smoke, loss of power
Spark	coil, spark plug	no-start, misfire
Mechanical	piston, crankshaft, crankcase	knocking, low compression
Exhaust	muffler	loud operation, power loss

Parts on the tractor that are often confused with “engine parts”

On riding mowers, some problems feel like engine trouble but come from the deck or drive system:

• Ground drive belt (moves the tractor): lawn tractor ground drive belt, 1/2 x 82-in 532140294
• Blade drive belt (spins the cutting blades): lawn tractor drive belt 532144200
• Mulching blade (cuts grass, not part of the engine): husqvarna lawn tractor mulching blade, 21-in 532134149

Why it matters

Knowing which system you are dealing with helps you troubleshoot faster. For example, a no-start usually points to fuel, spark, or safety interlocks, while “won’t move” is commonly a belt or transmission issue.

For the Craftsman riding mower model 917271042, the exact engine make and model varies by build and prior service history; we identify it by checking the engine ID tag on your tractor. Most Craftsman front-engine lawn tractors in this class use a single-cylinder gasoline engine.

How to identify the engine on model 917271042

Look for the engine identification label, then record the numbers exactly as shown.

• Check the valve cover or blower housing for an ID sticker or stamped plate
• Write down the engine model, type, and code (common on Briggs and Stratton)
• If it is a Kohler engine, record the spec number along with the model
• Compare the ID to your parts diagrams before ordering ignition, carburetor, or muffler parts
• If the label is missing, use the tractor’s frame tag plus visible engine features (starter location, air filter style, fuel pump) to narrow it down

Common engine brands you may see on Craftsman tractors

These are the most common engine families used on many Craftsman riding mowers; your ID tag confirms which one you have.

Engine brand	Typical ID format you will see	Why it matters for parts
Briggs and Stratton	Model / Type / Code	Tune-up parts and carburetor kits are engine-specific
Kohler	Model plus spec number	Spec number controls the correct starter, regulator, and gaskets
Tecumseh (older units)	Model and spec	Parts availability varies; exact ID is critical

Parts that often depend on the engine ID

Even on the same tractor model, these items can differ by engine version.

• Air filter and pre-filter
• Spark plug and ignition coil
• Carburetor or carburetor rebuild kit
• Fuel filter and fuel shutoff solenoid
• Muffler and exhaust hardware (for example, the exhaust muffler 532159420)

Why it matters

Using the engine ID prevents ordering the wrong tune-up or fuel system parts. The tractor model number (917271042) identifies the chassis and deck; the engine tag identifies the correct engine parts.

If the engine cranks but will not start, we use the same ID information to troubleshoot spark and fuel issues; the steps in riding lawn mower engine spins but wont start video align with the most common causes.

For this Sears PartsDirect model page, the Craftsman 42-inch riding mower model number is 917271042. If you are looking at a different Craftsman 42-inch mower, the model number can vary by series and year, so matching the number on your tractor’s ID tag is the fastest way to confirm parts fit.

Where to find the model number on the tractor

On most Craftsman riding mowers and lawn tractors, the model number is printed on an ID label in one of these common spots:

• Under the seat (seat pan area)
• On the rear fender or frame near the seat
• Under the hood near the engine compartment
• On the frame rail near the front axle

Why “Craftsman 42-inch” is not enough by itself

“42-inch” usually describes the cutting deck width, not the exact tractor model. Craftsman used multiple 42-inch deck configurations over time, and parts like belts, blades, and mandrel components can differ.

Quick fit-check examples for model 917271042

What you are replacing	What must match	Example part for this model
Blade (42-inch deck)	Deck type and blade mounting pattern	Husqvarna lawn tractor mulching blade, 21-in 532134149
Ground drive belt	Belt length and width	Lawn tractor ground drive belt, 1/2 x 82-in 532140294
Blade drive belt	Belt length and width	Lawn tractor drive belt 532144200

Why it matters

Using the exact model number (917271042) helps us narrow your Craftsman tractor to the correct diagrams and parts list, which prevents ordering the wrong deck belt, mandrel assembly, or blade style.

For Craftsman model 917271042 with a 42-inch deck, the belt size depends on which belt you mean: the blade drive (deck) belt or the ground drive belt. For this model, our listed belts are 1/2-inch wide and either 88 inches (deck belt) or 82 inches (ground drive belt).

Identify which belt you need

Most “42-inch riding mower belt” questions refer to the deck belt that spins the blades, but the tractor also uses a separate belt to drive the transmission.

• Deck belt (blade drive belt): runs from the engine pulley to the mower deck pulleys
• Ground drive belt: drives the tractor forward and reverse
• If your issue is “blades won’t engage,” focus on the deck belt and idler system
• If your issue is “tractor won’t move,” focus on the ground drive belt and pulleys

Belt options for Craftsman 917271042 (42-inch deck)

Belt type	Listed part	Listed size	Common symptom when worn
Blade drive (deck) belt	Lawn tractor drive belt 532144200	1/2 x 88-in	Blades slip, squeal, or stop in heavy grass
Ground drive belt	Lawn tractor ground drive belt, 1/2 x 82-in 532140294	1/2 x 82-in	Tractor slows, won’t climb, or won’t move

Why belt size matters

A belt that is even slightly too long can slip and burn; a belt that is too short can over-tension the idler arm, damage bearings, or prevent proper engagement. Matching the correct belt to the correct system (deck vs. ground drive) prevents repeat failures.

Quick checks before you order

• Confirm whether the problem is blade drive or ground drive
• Inspect for glazing, cracks, frayed cords, or a “V” that looks flattened
• Spin deck pulleys by hand; roughness points to a bad mandrel or bearing
• Check idler pulleys and springs for free movement and proper tension

Craftsman model 917271042 was made during the LT1000-era production run (typically late 1990s through mid-2000s), but the exact build year is identified by the product identification label on the tractor (usually under the seat or on the rear fender area). Use that label to match the manufacturing date and engine family.

How to find the exact year on your 917271042

Check the tractor’s ID label first; it is the fastest way to pin down the year without guessing.

• Lift the seat and look for a white or silver sticker with the model and serial numbers
• Check the rear fender pan area if you do not see it under the seat
• Write down the full serial number exactly as shown
• Also note the engine model/type/code stamped on the engine (Briggs & Stratton or Kohler, depending on what’s installed)
• Use the serial and engine code together when ordering parts or confirming production details

What “917” means (and why it matters)

Many Craftsman riding mowers with model numbers starting with 917 were built for Sears by a major OEM (commonly AYP/Husqvarna group). That is why you may see Husqvarna-labeled replacement parts that still fit your Craftsman tractor.

Why it matters

Knowing the exact year helps you get the right deck, belt routing, and steering or mandrel parts the first time, especially when similar LT1000 tractors changed pulleys, spindles, and guards across different years.

Parts that often vary by year (examples)

If you are troubleshooting fitment or replacing worn deck components, these are common “year-sensitive” items:

System	Part type	Example from this model’s parts list
Mower deck	Blade	Husqvarna lawn tractor mulching blade, 21-in 532134149
Mower deck	Mandrel/spindle	Husqvarna lawn tractor mandrel assembly 532130794
Drive	Ground drive belt	Lawn tractor ground drive belt, 1/2 x 82-in 532140294
Mower deck drive	Blade drive belt	Lawn tractor drive belt 532144200
