Craftsman 917378841 gas walk-behind lawn mower Parts

For Craftsman model 917378841, the serial number is printed on a decal on the rear of the mower housing. Use that serial number (and your recorded purchase date, if available) to determine the mower’s age; the serial is the key identifier for date lookups.

Where to find the model and serial number

Check the decal on the rear of the mower housing; it lists both identifiers.

• Look on the back (rear) of the deck/housing, not the handle
• Write down the model number (917378841) and the serial number exactly
• Record the date of purchase if you still have it (receipt, warranty card, or notes)
• Take a clear photo of the decal in case the print is worn

How to use the serial number to estimate age

Once you have the serial number, compare it to your purchase records first; that is the fastest way to pin down the mower’s age.

What you have	What it tells you	Best next step
Serial number only	Identifies the production run	Use the serial for a date lookup and compare to maintenance history
Serial number + purchase date	Confirms “in service” age	Use purchase date as your practical age reference
Model number only	Identifies the parts list, not the build date	Find the serial number on the rear decal

Why it matters

Knowing the mower’s age helps us match the right Craftsman parts (like a drive belt, control cable, or wheel hardware) and plan maintenance intervals such as blade service, oil changes, and tune-ups.

Helpful reference

For decal location and recording the numbers, use the 917378841 owner’s manual.

Gas walk-behind mowers like the Craftsman 917378841 are still widely used and sold, but many areas are tightening rules on small gasoline engines over time. The practical trend is a gradual shift toward battery-powered equipment, not an immediate nationwide phase-out; check your local regulations and follow the maintenance and safety guidance in the 917378841 owner's manual.

What “phased out” usually means

Most changes happen in one of these ways:

• New sales restrictions in certain states or cities (often focused on small off-road engines)
• Fleet or commercial rules (landscaping companies, government purchasing)
• Noise and emissions ordinances that limit when or where gas equipment can be used
• Incentives and rebates that make battery mowers more attractive
• Product availability shifts as manufacturers expand cordless lineups

How to decide what to do with your 917378841

If your mower runs well, keeping it maintained is typically the most cost-effective choice.

• Keep fresh fuel and avoid long-term storage with untreated gasoline
• Replace wear items on schedule (blade, air filter, spark plug)
• Clean grass buildup under the deck to prevent poor cutting and power loss
• Store safely: let the engine cool and avoid storing with fuel indoors near ignition sources
• Plan ahead for parts you commonly replace each season

Common “keep it running” parts for this model

These are examples of parts categories the manual calls out as routine maintenance items.

Maintenance item	What it affects	When to address it
Blade and blade adapter	Cut quality, vibration	If cut is ragged or mower shakes
Belts	Self-propel drive	If mower will not move or slips
Air filter and spark plug	Starting and power	If hard starting or loss of power

If you are troubleshooting self-propel issues, the lawn mower wont move troubleshooting video motion drive failure is a good next step.

Why it matters

Local restrictions, fuel storage practices, and maintenance costs affect whether it makes sense to keep a gas mower or switch to battery. For the Craftsman 917378841, good fuel handling and routine tune-up items prevent the most common “won’t start” and “loss of power” problems.
