Craftsman 917257400 tractor Parts

On a Craftsman riding mower like model 917257400, the most reliable way to identify the year is by using the serial number and date-of-manufacture code on the product ID label, then confirming the format in the 917257400 owner's manual. Many Craftsman-built tractors use a 6-digit date code that reads MMDDYY.

Where to find the date code or serial number

Look for a sticker or metal tag in one of these common locations:

• Under the seat pan (lift the seat)
• On the frame rail near the engine
• Near the rear axle or transaxle area
• Under the hood near the dash tower
• On the mower deck shell (less common)

How to read the code (common Craftsman format)

A common date code format is MMDDYY:

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

Example

Code	Interprets as	Year
072811	July 28, 2011	2011
031905	March 19, 2005	2005

If the label does not show a clear date code

Some labels show only a serial number. In that case, use these steps:

• Write down the full model number (917257400) and the entire serial number
• Compare the label format and ID locations shown in the 917257400 owner's manual
• Use the model and serial when ordering parts or requesting service (this is the same information typically needed for correct part matching)

Why it matters

Knowing the build year helps us match the correct parts and specifications for your tractor, especially for items that change over production runs (mower deck components, belts, and electrical parts like a starter solenoid).

For the Craftsman 917257400 front-engine lawn tractor, use the engine oil type and viscosity listed in the 917257400 owner's manual. Most Craftsman riding mowers of this design use a 4-cycle engine oil such as SAE 10W-30 for typical mowing temperatures, with SAE 30 often used in consistently warm weather.

How to choose the right oil for your conditions

Use these common guidelines, then match them to the temperature chart and specs in your manual.

• SAE 10W-30: best all-around choice for changing spring and fall temperatures
• SAE 30: good for steady warm-weather mowing
• Synthetic 5W-30: helps cold starts and wider temperature swings
• Avoid 2-cycle oil: this tractor uses a 4-cycle engine oil system
• Do not overfill: check level on the dipstick after adding oil

Quick oil selection table

Outdoor temperature range	Common oil choice	What you get
Cool to mild	10W-30	Easier starting, good protection
Warm and steady	SAE 30	Simple, stable viscosity
Cold starts common	Synthetic 5W-30	Faster lubrication at startup

Oil change tips that prevent engine wear

The manual’s storage section calls out changing engine oil at season end; that same practice helps year-round reliability.

• Run the engine a few minutes to warm the oil (it drains better)
• Park on level ground, set the parking brake, remove the key
• Drain completely, then refill slowly and recheck the dipstick
• Wipe spills off the frame and deck to reduce dirt buildup

Why it matters

Correct viscosity keeps the engine lubricated at startup and under load. Oil that is too thick can make starting harder; oil that is too thin can increase wear when the engine is hot.

For the Craftsman front-engine lawn tractor on this page, the model number is 917257400. If you are asking about a different Craftsman 42-inch riding mower, the model number is printed on the tractor’s model and serial number label; confirm it there before ordering parts.

Where to find the model number on a Craftsman riding mower

We recommend checking the model and serial number label on the tractor (not the mower deck). Common locations include:

• Under the seat pan or on the seat bracket
• On the rear fender or rear frame area
• On the frame near the engine compartment
• Near the transaxle area on the rear frame rail
• Inside the hood area on the chassis

For diagrams and label-location guidance specific to this tractor, use the 917257400 owner's manual.

Why the “42” description is not a model number

“42-inch” usually describes the mower deck cutting width, not the tractor model. Craftsman uses the model number to match the correct parts list for items like blades, belts, mandrel assemblies, and steering components.

Quick identification: what to match before buying parts

• Model number (example: 917257400)
• Product type (front-engine lawn tractor)
• Deck size (often 42-inch on many Craftsman tractors)
• Engine family (varies by build)
• Serial number (helps confirm production run)

Common 42-inch deck parts you may need (examples)

Once you confirm the tractor model number, you can match common wear items. For model 917257400, examples include:

Part type	Example part for this model	What it affects
Mulching blade	Husqvarna lawn tractor mulching blade, 21-in 532134149	Cut quality and mulching
High-lift blade	Lawn tractor 42-in deck high-lift blade 532138971	Bagging and discharge lift
Ground drive belt	Lawn tractor drive belt 532138255	Forward and reverse drive

Why it matters

Using the exact model number prevents ordering the wrong blade set, belt length, or deck hardware, which can cause poor cutting performance, belt slip, or fit issues.
