8 Common Problems Encountered During Lawn Mowing (Causes & Solutions)
1. Uneven cutting with rough grass stubbles
- Causes: Dull blades, reversed blade installation, excessively low cutting height, wet and overgrown grass
- Solutions: Sharpen or replace blades; raise cutting height first for finishing trim; never mow wet grass
2. Grass clogging, grass bag leakage and poor grass collection
- Causes: Wet grass sticking to the deck, overlong grass, blocked discharge chute
- Solutions: Clean the deck before mowing; mow in passes; empty the grass bag timely
3. Mower fails to start with no response when pressing the switch
- Causes: Loose battery connection, low battery, unlocked safety interlock, overheat protection activation
- Solutions: Reinsert the battery; fully charge the battery; let the machine cool for 10–15 minutes before restarting
4. Actual battery runtime shorter than advertised
- Causes: High power consumption from thick grass and slopes, battery aging, low-temperature power loss
- Solutions: Prepare a spare battery; avoid continuous heavy-load mowing
5. Excessive vibration and abnormal noise
- Causes: Loose or deformed blades, loose body screws, grass tangled around the deck
- Solutions: Fasten blades; remove debris; check all fastener screws
6. Poor climbing performance and heavy pushing
- Causes: No power assistance on push mowers, excessive slope, grass winding on wheels
- Solutions: Mow across slopes; clear grass around wheels; choose self-propelled mowers for slopes
7. Battery charging failure and rapid power drain
- Causes: Dirty battery contacts, incompatible charger, long-term storage with empty battery
- Solutions: Clean battery contacts; use original charger; avoid long-term low-battery storage
8. Yellowed and bare lawn patches after mowing
- Causes: Over-short single cutting, damaged grass stems from dull blades, repeated rolling on the same area
- Solutions: Only cut 1/3 of grass height each time; keep blades sharp
Exclusive Tips for Greenworks 40V 16-inch Lawn Mower
- Advantages: Lightweight, easy to push, low noise, universal battery, extremely simple maintenance
- Limitations: Non-self-propelled, laborious on slopes; requires slow pushing for long thick grass; moderate efficiency of 16-inch cutting width
- Optimal usage: Regular lawn maintenance only, do not let grass grow excessively; mow on dry grass; clean the cutting deck after each use
Final Buying Conclusion
- For lawns ≤600㎡ with flat/gentle slopes pursuing quiet and convenient maintenance: this model is highly recommended
- For large lawns, abundant thick grass and frequent slope mowing: Upgrade to self-propelled higher-voltage models
