The Dual-Blade System is a critical feature in robotic lawn mowers designed for thick grass, offering superior cutting efficiency, durability, and adaptability. Below is a detailed analysis of its advantages and technical specifications, supported by data from remote-controlled mower designs.
Why Dual-Blade Systems Excel for Thick Grass
Enhanced Cutting Power
Dual blades rotate at high speeds (e.g., 6000 RPM), doubling the cutting frequency compared to single-blade systems. This reduces clumping and ensures even mulching.
The LyCut dual-blade design (observed in some models) increases cutting width (e.g., 405 mm), improving coverage and reducing missed spots.
Improved Mulching & Grass Health
Dual blades finely chop grass clippings, distributing them as natural fertilizer. Integrated high-speed fans further disperse clippings uniformly.
Reduces manual cleanup and promotes healthier regrowth.
Durability & Terrain Adaptability
Thick grass often includes debris (e.g., twigs). Dual-blade systems paired with hey-duty motors (e.g., 300W rated, 1200W peak) withstand tougher conditions.
Some systems feature adaptive floating decks to maintain consistent cutting height (30–100 mm) on uneven terrain.
Efficiency & Battery Optimization
Dual blades reduce strain on individual blades, extending lifespan.
Balanced load distribution improves energy efficiency, critical for robotic mowers operating on LiFePO4 batteries.
Technical Comparison: Single vs. Dual-Blade Systems
| Feature | Single-Blade System | Dual-Blade System |
|---|---|---|
| Cutting Width | 250–300 mm | 350–405 mm |
| RPM | 3000–4000 | 5000–6000 |
| Grass Handling | Struggles with thick grass | Efficient for dense growth |
| Mulching Quality | Moderate | Excellent |
| Terrain Adaptability | Limited | High (floating deck) |
Key Applications
Residential Lawns: Ideal for tall fescue, Bermuda, or mixed grasses.
Commercial Landscapes: Handles large, dense areas with minimal maintenance.
For optimal performance, dual-blade systems should integrate AI nigation (e.g., RTK-VSLAM) to oid obstacles while maintaining cutting precision.
