How Will Tall Grass Affect Your Lawn Mower Performance?
Tall grass can have a significant impact on the performance of your robotic lawn mower, especially if it’s not designed to handle such conditions. Here are the main factors that can diminish the efficiency of your robotic mower:
- Battery and Power Consumption: Cutting through tall grass can drain your mower's battery much faster, requiring more frequent recharges.
- Potential Damage to Your Lawn: It’s generally advisable to only trim one-third of the grass height at a time. Cutting tall grass all at once can shock the plants, weakening them and making them more vulnerable to pests and diseases.
- Strain on your Mower: TTall grass can put extra stress on the mower's motor and battery, leading to overheating or potential damage to components like the belt and blades.
