Craftsman 917255470 lawn tractor Parts

A 547cc engine typically produces about 14 to 18 horsepower, depending on the engine design and the RPM where horsepower is measured. For Craftsman model 917255470, the tractor is identified in our documentation as a 14 HP model; see the 917255470 owner's manual for the model-specific engine listing.

Quick way to estimate horsepower from cc

Engine displacement (cc) is only one piece of the puzzle. Horsepower changes with RPM, compression, carburetion or fuel injection, governor settings, and emissions tuning.

Common real-world ranges for small 4-cycle mower engines:

• 500 to 600cc: usually 14 to 20 HP
• Single-cylinder engines often land on the lower end of the range
• V-twin engines often land on the higher end of the range
• Peak HP is usually higher than the “working” HP you feel under load

What we know for Craftsman 917255470

In the parts and wiring documentation for model 917255470, the tractor is labeled as a 14 HP 38-inch tractor. That means the correct horsepower to use for this specific model is 14 HP, even if another brand’s 547cc engine advertises a different number.

Why the numbers can look different

Spec you see	What it usually means	Why it varies
cc (displacement)	Engine size	Does not account for RPM or tuning
HP (horsepower)	Power output	Can be rated at different RPMs
Torque	Pulling strength	Often a better indicator for mowing load

Why it matters

Matching the correct horsepower for your exact tractor helps when you are selecting maintenance parts (belts, pulleys, and engine components) and when you are comparing performance expectations for mowing, towing, and hill use.

For the Craftsman lawn tractor model 917255470, the engine manufacturer is Briggs & Stratton (engine model 287707, type 0115-01). For this tractor, the manual’s engine parts breakdown is specifically labeled as a Briggs & Stratton engine. See the 917255470 owner's manual for the engine identification and parts listing.

How we identify the engine maker on this model

The most reliable way to confirm who makes the engine is to match the tractor model number to the engine section in the documentation.

• Look for the engine model and type in the engine parts section
• Match the tractor model number 917255470 to the engine pages
• Use the engine’s model-type-code on the blower housing tag when ordering parts
• Confirm you are not mixing up marketing names (like IntelliPOWER) with the actual engine OEM

What to check on the engine itself (fast confirmation)

On most Briggs & Stratton single-cylinder riding mower engines, the ID tag is on the blower housing or valve cover area.

What you’ll see	What it tells you	Why it matters
Engine brand name	Briggs & Stratton	Confirms the OEM
Engine model number	287707	Needed for correct parts lookup
Type number	0115-01	Narrows down exact configuration

Why it matters

Engine parts (starter, carburetor parts, ignition parts, filters) are selected by the engine model and type, not just the tractor model. Using the Briggs & Stratton identifiers prevents wrong-part returns and speeds up repairs.

For a Craftsman riding mower like model 917255470, the most reliable way to identify the build year is to use the serial number on the product ID tag and decode the date code (many use a MMDDYY pattern). Confirm the exact tag location and format in the 917255470 owner's manual.

Where to find the serial number tag

On most Craftsman riding lawn tractors, the product ID tag is easy to spot once you know where to look.

• Under the seat pan or on the seat deck
• On the rear fender area near the seat
• On the frame rail near the engine compartment
• Near the transaxle area on the frame

How to decode the year from the serial number

Many Craftsman-built riding mowers use a 6-digit date code embedded in the serial number.

• First 2 digits: month (MM)
• Next 2 digits: day (DD)
• Last 2 digits: year (YY)

Example

If the first six digits are 071294, that reads as July 12, 1994.

Quick reference table

Use this to sanity-check what you are reading off the tag.

Code pattern	What it means	Example	Result
MMDDYY	Month, day, year	071294	July 12, 1994
MMDDYY (embedded)	Same, but appears within a longer serial	XX071294XX	July 12, 1994

If your tag does not match MMDDYY

Some Craftsman walk-behind mowers and a few tractor variants use a different serial format. When that happens, we use the model number (917255470) plus the full serial number to match the correct production run and parts list.

• Write down the entire serial number (not just the first 6 digits)
• Compare the tag format and examples shown in the 917255470 owner's manual
• Use the decoded year to choose correct maintenance parts (belts, tires, pulleys) for your exact build

Why it matters

The production year helps ensure you get the right replacement parts and service procedures, especially for items that change across runs like a drive belt, blade drive belt, or deck hardware.

For the Craftsman lawn tractor model 917255470, use 4-cycle engine oil with a viscosity that matches your outdoor temperature; the tractor is shipped with summer-weight oil, and you switch to a lighter viscosity for cold-weather starting. For the exact viscosity chart and service details, use the 917255470 owner's manual.

How to choose the right oil viscosity

We match oil viscosity to temperature because it affects starting, lubrication, and engine wear.

• Warm weather mowing: use the manual’s summer-weight recommendation
• Cold weather operation (below 32°F / 0°C): change to the manual’s cold-weather viscosity for easier starting
• Always use 4-cycle oil: never use 2-cycle oil in this engine
• Keep oil at the FULL mark: low oil can damage the engine
• Check oil on level ground: for an accurate dipstick reading

Oil service schedule (what we follow)

The manual calls out a break-in oil change and a regular interval after that.

Maintenance item	When to do it	Why it matters
First oil change	After the first 2 hours of operation	Removes break-in debris
Routine oil changes	Every 25 hours or at least once a year	Prevents sludge and wear
Oil level checks	Before starting and after each 8 hours of continuous use	Prevents low-oil damage

Quick oil check and change tips

• Let the engine cool enough to work safely; warm oil drains faster during changes
• Remove the dipstick, wipe it clean, reinstall, then recheck the level
• Do not overfill; keep the level at the FULL line on the dipstick
• Catch and dispose of used oil properly

Why it matters

Using the correct oil viscosity helps the 917255470 start easier in cold weather and stay properly lubricated in heat; following the 2-hour and 25-hour intervals reduces engine wear and extends engine life.

For a Craftsman riding mower like model 917255470, we look up the model number on the model plate under the seat. Lift the seat and read the plate; record the model and serial numbers so you can match the correct parts list and diagrams in the 917255470 owner's manual.

Where to find the model and serial number

On Craftsman lawn tractors, the identification plate is typically mounted on the frame under the seat.

• Park on a flat surface, set the parking brake, and turn the key off
• Lift the seat up and look for the model/serial plate on the frame
• Write down the model number and serial number exactly as shown
• Keep the numbers with your maintenance records for future parts lookups
• If the plate is dirty, wipe it gently so every digit is readable

Tractor model number vs. engine model number

Your tractor and engine use different model numbers. For parts accuracy, we match the part to the correct number.

What you are identifying	Where to look	What it’s used for
Tractor model number (example: 917255470)	Plate under the seat	Mower deck, belts, steering, chassis, wheels
Engine model number	On the engine blower housing	Engine-specific parts (carburetor, ignition, gaskets)

Why it matters for ordering parts

Using the exact model number prevents wrong-fit parts, especially on common wear items like belts, tires, and deck hardware.

• Drive and deck belt routing can vary by model
• Wheel and tire sizes can differ by rim and axle setup
• Deck mandrel and pulley styles change across tractor series

If you are replacing wheel hardware after confirming your model, a common example part for this tractor is the hub cap 532104757 (match by part ID to avoid mix-ups).

For the Craftsman lawn tractor model 917255470, belt size depends on which belt you mean (ground drive belt vs mower deck blade drive belt). We match belts by the OEM part number for your exact deck and drive setup; confirm routing and belt type in the 917255470 owner's manual.

Identify which belt you need

Most riding tractors use at least two belts, and they are not interchangeable:

• Ground drive belt: drives the transaxle so the tractor moves
• Blade drive (deck) belt: spins the mower blades
• Secondary deck belts (some setups): used on certain deck designs

A quick check: if the tractor will not move, suspect the ground drive belt; if it moves but will not cut, suspect the deck belt.

Belt options we commonly see for this model

Based on the parts listed for model 917255470, these are the two belt types you will most often replace:

Belt type	What it drives	Common identifier for this model	Typical size shown on part listing
Ground drive belt	Rear wheels (transaxle)	Lawn tractor drive belt 532125907	1/2 x 90-in
Blade drive belt	Mower deck blades	Lawn tractor drive v-belt 532144200	1/2 x 88-in

How to confirm the correct belt (best practice)

We recommend confirming before ordering because belt routing and deck configuration matter.

• Check the belt routing decal (often under the hood or on the deck)
• Compare your old belt’s printed number (if readable)
• Measure the old belt length if the number is worn off
• Verify the belt path and pulley locations in the 917255470 owner's manual
• Inspect idler pulleys and guides; a seized pulley can destroy a new belt quickly

Why it matters

Using the wrong belt length or profile can cause slipping, poor blade speed, premature belt wear, or the belt jumping off the pulleys. Matching the correct Craftsman belt to the correct drive system keeps tension and routing correct.

The Husqvarna LGT2554 is typically equipped with a 54-inch cutting deck (often a 3-blade deck). For the exact deck size and the correct belt and blade specs for your specific tractor, confirm the deck information in your 917255470 owner's manual.

How to confirm deck size on your tractor

• Measure the cutting width from the left blade tip to the right blade tip (with blades aligned side-to-side).
• Check the deck model/serial label on the mower deck shell.
• Count blades; many 54-inch decks use 3 blades.
• Compare your deck belt routing and pulley layout to the diagrams in the manual.
• If you are replacing deck parts, match by deck size and configuration, not just tractor name.

Why the model number matters (LGT2554 vs. Craftsman 917255470)

“LGT2554” is a Husqvarna tractor designation, but this Sears PartsDirect page is for Craftsman model 917255470, which the manual identifies as a 14 HP 38-inch tractor with a 38-inch mower.

Quick comparison

Item	Husqvarna LGT2554 (common spec)	Craftsman 917255470 (manual spec)
Deck size	54 in	38 in
Blade count (typical)	3	2 (typical for 38 in decks)
Deck belt length (varies)	Varies by deck	88-1/2 in mower belt listed in parts section

Parts tip if you are shopping by deck size

If your goal is to buy deck parts (belt, mandrel, idler pulley), match the parts to the deck on the tractor you own:

• For the Craftsman 917255470 38-inch deck, the manual parts list includes a mower V-belt; a common replacement on this model page is the lawn tractor drive v-belt 532144200 (verify application by deck and routing).

Why it matters

Deck size drives the correct blade length, belt length, mandrel assemblies, and idler pulley setup. Ordering by the wrong deck size is the fastest way to end up with a belt that will not route correctly or blades that do not fit.

A “Craftsman 6.75” description by itself is not a single model number; Craftsman used 6.75 HP on multiple walk-behind mowers. For an exact match, we use the model number from the mower’s ID label, then confirm it in the Craftsman 917255470 owner's manual.

Where to find the model number on a Craftsman mower

On Craftsman equipment, the model number is printed on a product ID label (sometimes called a model plate). Common locations include:

• Rear of the mower deck near the discharge chute
• On the back of the deck between the rear wheels
• Under the seat on riding models (like model 917255470)
• Near the engine mounting area on the frame
• On the handle support brackets (some walk-behind designs)

What “6.75” usually refers to

“6.75” is typically an engine power rating used in marketing and on decals; it does not uniquely identify the mower. Two mowers can both say 6.75 but use different decks, wheels, belts, and blade systems.

Quick ID checklist (what to write down)

• Full model number (often starts with 917.)
• Product number (if listed)
• Serial number
• Deck size (example: 21 inch)
• Engine model number (found on the engine blower housing)

Model number vs. engine model number

Use this as a quick guide when you are ordering parts.

Item you’re identifying	Where it’s found	What it’s used for
Mower model number (example: 917.xxxxxxx)	Product ID label on the mower	Correct parts diagrams and chassis parts
Engine model number	Engine blower housing	Engine-specific parts (carburetor, starter, air filter)

Why it matters

Parts fit is driven by the mower model number, not the 6.75 rating. Using the exact model number prevents ordering the wrong blade, drive belt, or wheel components.
