The performance of a lawn mower is not solely dependent on its specific components such as engine power or cutting deck. The sharpness of the lawn mower blades plays a significant factor when it comes to creating a manicured and clean-cut lawn.
Dull cutting blades cause ragged tears on the grass blades as these cutting blades rip and pull them off instead of cutting them smoothly. Sharpened blades do not only cut cleanly, but it also helps the plants heal and recover quickly. Lawn mower blades with dull edges do only result in a poorly mowed lawn but can also extend the lawn mowing time.
