How Can You Properly Maintain Your Push Gas Lawn Mower for Longevity?
Proper maintenance of your push gas lawn mower is essential for ensuring its longevity and optimal performance.
- Regular Oil Changes: Changing the oil regularly is crucial for keeping the engine lubricated and preventing wear and tear. Typically, you should change the oil after every 20-50 hours of use, or at least once a season, using the manufacturer’s recommended oil type.
