# The Dangers of Wet Grass: How to Safely Use a Lawn Mower in Damp Conditions
Mowing wet grass presents unique challenges that can compromise both your lawn's health and your safety. While robotic lawn mowers offer convenience, understanding the risks and proper techniques for damp conditions is crucial for effective lawn maintenance.
Why Wet Grass Poses Risks
Safety Hazards: Wet grass increases slip risks for manual mowers and can cause traction issues for robotic models.
Equipment Damage: Moisture accelerates corrosion in metal components and may short-circuit electrical systems.
Lawn Health: Wet grass tears rather than cuts cleanly, leing ragged edges vulnerable to disease.
Robotic Lawn Mower Considerations
Modern robotic lawn mowers feature rain sensors and slip-resistant wheels, but performance varies:
| Feature | Wet Grass Performance | Dry Grass Performance |
|---|---|---|
| Traction | Reduced (30% more wheel slippage) | Optimal |
| Cutting Efficiency | 15-20% slower due to clumping | Peak performance |
| Battery Drain | Up to 25% faster | Normal runtime |
Best Practices for Damp Conditions
Timing Matters:
Wait 2-4 hours after rainfall
Mow during late morning when dew evaporates
Robotic Mower Adjustments:
Increase cutting height by 20%
Enable "wet grass mode" if ailable
Clear boundary wires of debris
Maintenance Tips:
Wipe blades dry after use
Check wheel treads for grass buildup
Inspect electrical contacts weekly
When to Avoid Mowing Entirely
Postpone mowing if:
Standing water is present
Soil feels spongy underfoot
Thunderstorms are forecast within 6 hours
For robotic models, hey rain may trigger automatic shutdown systems. Always consult your manual for moisture tolerance specifications.
By following these guidelines, you can minimize risks while maintaining a healthy lawn—even when weather conditions aren't ideal.
