Craftsman Gas Walk-Behind Lawn Mower 917378460 FAQs

Gas walk-behind mowers like the Craftsman 917378460 are not being phased out everywhere at once; the shift is gradual and depends on where you live, because some areas are restricting new sales while many others still allow gas equipment and support parts and service.

What to expect (sales vs. ownership)

Even where new gas mower sales are restricted, owners typically can keep using and maintaining existing mowers. For the Craftsman 917378460, routine maintenance and common wear-part replacement (blade hardware, wheels, cables, tune-up items) keeps the mower reliable for years.

  • You may see fewer new gas models on store shelves over time.
  • Parts support remains important because many gas mowers stay in service long after purchase.
  • Maintenance becomes the deciding factor in lifespan more than “phase-out” headlines.
  • Local rules often focus on new sales, not continued use.
  • Electric options are growing because they are quieter and lower-maintenance.

Practical maintenance that keeps a gas mower worth owning

Our best advice is to maintain what you have. The manual emphasizes basics like safe servicing (stop engine, disconnect spark plug wire) and regular cleaning under the deck and drive cover. Use the owner's manual for model-specific procedures and safety steps.

Common upkeep items for this model include:

  • Keep the underside of the mower housing clean after each use (scrape buildup).
  • Clean under the drive cover at least twice a season.
  • Avoid spraying water into the engine, muffler, air filter, or carburetor.
  • Use fresh fuel; do not store old gasoline season to season.
  • Replace tune-up parts on schedule (spark plug, air filter, oil).

Helpful part examples (when wear shows up)

If you are fixing a drive or cutting issue, these model-matched parts are commonly involved:

Symptom Often related area Example part for this model
Engine runs but mower will not propel Drive control linkage Drive flat bail 583107601
Engine stops when you release the handle Operator presence/zone control Lawn mower zone control cable 532133107
Vibration or blade feels loose Blade mounting hardware Lawn mower blade adapter 581547901

Why it matters

If your area is shifting toward electric, keeping your Craftsman 917378460 maintained protects your investment and avoids downtime. A well-maintained gas mower also starts easier, runs cooler, and cuts more consistently.

On Craftsman model 917378460, the serial number is printed on a decal on the rear of the mower housing; once you have that serial number, you can use the manufacturer’s date-code format (mower or engine) to determine the build month and year. The best reference is the 917378460 owner's manual.

Where to find the serial number on this mower

The manual for model 917378460 places the model and serial numbers on a decal on the rear of the mower housing.

  • Check the rear of the deck (mower housing) for the decal
  • Write down the model number and serial number exactly as shown
  • Record the date of purchase for your maintenance history
  • Clean the decal gently with a damp rag and mild soap, then dry it

How to decode the mower’s age from the serial number

Walk-behind mowers typically use one of these methods to encode the build date:

  • A date code embedded in the serial (often month and year)
  • A manufacturer code that maps to a production date
  • An engine identification code (common on Briggs & Stratton engines)

Common date-code patterns

What you see in the serial What it usually means Example result
Starts with 4 digits like MMYY Month, then year 0419 = April 2019
Starts with 4 digits like YYMM Year, then month 1904 = April 2019
Includes 6 digits like MMDDYY Full date 041519 = April 15, 2019

Why it matters

Knowing the build date helps us match the correct Craftsman parts because manufacturers sometimes change components mid-production (for example, control cables, wheels, or hardware).

If the decal is missing or unreadable

  • Take a clear photo in bright light and zoom in
  • Look for an engine ID tag on the engine shroud; engine model and code numbers often identify the build date
  • If you are servicing the handle controls, compare your parts to the diagrams and listings in the 917378460 owner's manual

Last updated: January 2026

The model number is 917.378460 (often written without the dot as 917378460) for this Craftsman gas walk-behind lawn mower. You can also confirm it on the model and parts list pages in the 917378460 owner's manual.

Where to find the model number on the mower

We typically see the model number on the mower’s ID label, not on the engine itself.

  • Check the rear of the mower deck near the discharge opening
  • Look around the handle mounting area (left or right side)
  • Check near the rear door or bagger opening
  • Wipe dirt and grass residue off the label so the digits are readable

Model number vs. engine number (common mix-up)

The mower model number identifies the Craftsman unit; the engine has its own separate model/type/code.

What you’re reading What it identifies Example format
Mower model number The Craftsman mower (parts diagrams match this) 917.378460 or 917378460
Engine model/type/code The engine manufacturer’s build info Varies by engine

Why it matters

Using the correct mower model number ensures you get the right parts for the drive system, wheels, control cables, and deck hardware. For example, the parts list for model 917.378460 includes items like the drive flat bail 583107601 and the lawn mower zone control cable 532133107.
