Best Lawn Mower Blade Sharpener in 2018

While using a lawn mower, whether gasoline or electric, it is important to monitor the condition of the cutting headset – a blade or blades (depending on the model). Regularly inspect the blade for integrity: damages, deformations and chips. Any violation of integrity affects not only the correct operation of the mechanism but also safety. A deformed or cracked knife can break at any time and debris can cause considerable harm to the rider! Also, the deformed cutting device rotates in imbalance with the engine, which directly affects the service life. Therefore, even if you do not see the deformation visually, but feel an increased vibration during operation, it would be better to stop the work immediately and contact the specialists if the vibration remains after lawn mower blade sharpening.

A simple knife replacement can help, but unfortunately not always! As a rule, deformation of a knife is a consequence of a blow against an obstacle. Most lawn mowers are designed so that the blade is attached to the engine master, by means of a coupling. And often when a blow can be bent not only the knife, but also the motor shaft.

By the way, do not try to level the cutting part! You are unlikely to succeed, the knives of lawn mowers are not just a metal strip. Virtually all of them have a special shape, for better mulching and ejection of grass. If you really want to give a second life to the cutting devices of your grass cutter, purchase a professional lawn mower blade sharpener, as it may solve all the issues.
