Craftsman 917389011 lawn mower Parts

A gas walk-behind lawn mower like Craftsman model 917389011 typically lasts about 10 years with normal residential use. Lifespan depends most on maintenance (oil changes, air filter service, blade care) and keeping the deck and engine clean per the 917389011 owner's manual.

Typical lifespan by mower type

Most homeowners see these averages when the mower is maintained and stored properly:

Mower type	Typical lifespan	Notes
Push (manual) walk-behind	8 to 12 years	Fewer drive parts to wear out
Self-propelled walk-behind	7 to 10 years	Drive system adds wear items
Riding mower	10 to 15 years	More maintenance points
Zero-turn mower	10 to 15 years	Heavy-duty, but higher upkeep

What makes a mower last longer

The biggest difference between a mower that lasts 5 years and one that lasts 10+ is routine upkeep.

• Change engine oil on schedule (more often in heat or heavy loads)
• Clean or replace the air filter regularly
• Replace the spark plug at least yearly
• Keep the underside of the deck scraped clean after mowing
• Keep engine cooling fins and exterior clear of debris (a hot-running engine wears faster)
• Store it clean and dry at the end of the season; stabilize or remove fuel for storage

Quick maintenance habits that protect the engine

The manual calls out two key practices that directly impact engine life: keeping the engine clean (to prevent overheating) and cleaning the underside of the mower after each use. We also recommend avoiding water intrusion around the muffler, air filter, and carburetor during cleaning.

Why it matters

A longer mower lifespan means fewer breakdowns during peak mowing season and lower total cost of ownership. Consistent maintenance also helps the mower cut cleaner, bag better, and start more reliably year after year.
