Craftsman 917255572 lawn tractor Parts

To tell the year of your Craftsman riding mower, we use the model and serial number information on the tractor’s ID label. For model 917255572, the most reliable method is to match the serial number format shown on the label with the date-coding guidance in your owner's manual.

Where to find the model and serial number

On most Craftsman front-engine lawn tractors, the ID label is typically located in one of these spots:

• Under the seat pan (lift the seat and look on the frame or fender area)
• On the rear fender near the seat
• On the frame rail near the engine compartment
• Near the footrest area on the chassis

How to decode the build date from the serial number

Many Craftsman tractors use a serial number where the first 6 digits represent a date code:

• First 2 digits = month
• Next 2 digits = day
• Last 2 digits = year

Example:

• 031398 = March 13, 1998

Some newer Craftsman products use a different format (including a letter code for the year). If your serial number does not look like a 6-digit date, use the format notes in the owner's manual and compare them to what’s printed on your label.

Quick checks to confirm you have the right label

Use these checks so you do not decode the wrong number:

• Confirm the model number reads 917255572 (not a deck or engine number)
• Look for wording like “MODEL NO.” and “SERIAL NO.”
• Ignore numbers stamped into the engine; those identify the engine, not the tractor
• If the label is damaged, write down every character you can still read before cleaning it

Why it matters

Knowing the year helps you choose the correct repair parts and diagrams for your Craftsman lawn tractor, especially for wear items like belts, deck components, and steering parts.

What you have	What it tells you	What it’s used for
Model number (917255572)	Tractor family and configuration	Matching parts diagrams and assemblies
Serial number	Build date code (varies by format)	Determining the mower’s year
Engine model/type	Engine identity	Engine-specific tune-up and repair parts

Yes, replacing the engine on your Craftsman lawn tractor model 917255572 is worth it when the tractor’s deck, steering, and drive system are still solid and the total engine-swap cost stays well below the cost of replacing the whole machine. If the tractor has multiple major wear issues, put the money into a replacement instead.

Quick decision checklist

• The mower deck is structurally sound (no major rust-through or cracks)
• The tractor still drives and stops correctly (brake and transmission feel normal)
• You can do the swap yourself or have a clear labor estimate
• You can still get common wear parts (belts, pulleys, switches) for this model
• The engine failure is truly internal (not a battery, solenoid, or safety switch issue)

Cost and condition: a simple rule of thumb

Use this to decide fast:

What you’re comparing	Good sign to replace engine	Bad sign (replace tractor)
Total engine swap cost vs. replacement tractor	Under ~50%	Around 50% or more
Deck condition	Straight, solid, serviceable	Rusted through, cracked, warped
Drive and cut system	Mostly normal	Multiple failures at once

Before you blame the engine (common “no start” look-alikes)

A lot of “dead engine” complaints are actually starting or interlock problems. Before committing to an engine swap, we check these first:

• Battery connections and battery condition
• Safety interlock system (seat switch, brake/clutch switch, PTO switch)
• Starter circuit components, especially the starter solenoid
• Fuel quality and basic tune-up items (old fuel, dirty air filter, spark plug)

If you hear a click but the engine will not crank, the riding lawn mower engine clicks but doesnt turn over video walks through the most common causes.

Why it matters

An engine swap can extend the life of a good tractor, but it does not fix worn deck hardware, belt routing issues, or safety problems. Your owner's manual also stresses safe service practices like disconnecting the spark plug wire before repairs and avoiding adjustments with the engine running.

Craftsman lawn tractor model 917255572 uses a gasoline engine, but the exact engine make, model, and horsepower are identified by the engine’s own ID tag, not by the tractor model number alone. Use the engine numbers and match them to the engine section of the owner's manual.

How to identify the exact engine on model 917255572

Look for the engine identification label or stamped numbers, then use those numbers when selecting engine parts.

• Turn the key off, remove it, and let the engine cool
• Open the hood and locate the engine ID tag (often on the blower housing or valve cover area)
• Record the model, type, and code (wording varies by engine brand)
• Use those numbers to cross-reference the engine parts breakdown in the owner's manual
• Order tune-up parts by engine ID to avoid mismatches (spark plug, air filter, fuel filter)

What the manual helps you confirm

The manual for 917255572 is the best place to verify the correct engine parts listing and service procedures for your specific build.

What you need	Where to find it on the tractor	How you use it
Engine model/type/code	Engine ID tag or stamping	Confirms exact engine family and parts fit
Engine parts breakdown	Manual engine repair parts section	Matches part illustrations to your engine
Maintenance specs	Manual maintenance section	Oil type, spark plug gap, service intervals

Why it matters

Craftsman tractors can be built with different engine variants across production runs. Using the engine ID prevents ordering the wrong ignition parts, filters, carburetor parts, or starter components.

“6.75” is an engine size label used on many Craftsman walk-behind mowers, so it is not a single model number. The model number is printed on your mower’s model tag; for Craftsman model 917255572 (a front-engine lawn tractor), the model plate is under the seat as shown in the owner's manual.

How to identify the correct model number

Use the model tag on the equipment, not the engine cover label.

• Look for a sticker or metal plate that says “MODEL” (often starts with 917 on Craftsman units)
• Record the full model number exactly as printed (including dots or dashes)
• Record the serial number too; it helps match the correct parts list
• If you are checking a walk-behind mower, look on the deck or rear frame (no seat)
• If you are checking a riding tractor like 917255572, look under the seat

Walk-behind mower vs. riding tractor: quick comparison

Item you’re identifying	Walk-behind mower (often labeled “6.75”)	Craftsman 917255572 lawn tractor
“6.75” marking	Common on engine shroud	Not the identifier for this tractor
Where the model number is found	Deck, rear frame, or handle mount area	Under the seat
What the model number is used for	Matching blades, wheels, drive parts	Matching belts, deck parts, steering parts

Why it matters

Craftsman used the same “6.75” engine class across many different mower builds. The model number is the only reliable way to match the correct blade, belt, wheels, and hardware for your exact unit.
