The Science Behind Dual Blade Mowing
Understanding the science behind how dual blade mowers work is crucial to appreciating their benefits. The primary mechanism involves the interaction between the two blades, which creates a more efficient cutting process.
Cutting Action and Air Flow
When a single blade cuts grass, it creates a lot of air turbulence and can leave the grass torn or shredded, especially if the blade is dull. In contrast, dual blade mowers utilize the principle of counter-rotating blades. The upper blade, often referred to as the primary blade, cuts the grass and lifts it upwards. Simultaneously, the lower blade, or the secondary blade, cuts the already lifted grass into finer pieces. This bi-blade cutting action not only ensures a cleaner cut but also improves the overall appearance of the lawn by reducing the amount of torn or shredded grass.
Aerodynamics and Vacuum Effect
Another significant aspect of dual blade mowers is the aerodynamic effect they produce. As the blades rotate, they create a vacuum effect that helps in lifting the grass for a cleaner cut. This effect also aids in the collection of clippings, making it easier to mulch or bag them, depending on the mower’s design and the user’s preference.
Benefits of Dual Blade Mowers
The advantages of using a dual blade mower are numerous and contribute to their popularity among lawn care enthusiasts.
Improved Cutting Efficiency
One of the most significant benefits of dual blade mowers is their ability to cut grass more efficiently.
