Let’s get that perfectly trimmed grass for your lawn!
Buying Guide
The first question you need to ask yourself is either you want an electric-powered lawn mower or a manual one. While each one has its pros and cons, both the types work very well. Electric blade sharpeners are costly as compared to manual ones but require very little physical power. For manual sharpeners, you will spend very less, but they need a lot of physical input from you. If you are looking for a good weekly workout routine for your arms, the manual one is a nice option for you. For people running short on time, electric sharpeners are an excellent option. You can also get a blade that connects with your standard drilling machine and then sharpens your lawn mower blade.
Electric Blade Motor Power
For electric sharpeners, one critical factor is the motor power. A blade with a motor power of ¼ or ½ HP is excellent. A higher motor power results in better performance but also consumes more energy to run.
Compatibility
One thing you may ignore is the compatibility of the sharper with your blade. The best way to do is to measure the blade size of your lawn mower and then to check it with the sharper. If it is compatible with your blade size, you are good to go with this sharpener.
Spinning Speed
Spinning speed means how many times the grinder will move in one minute, and it is measured in RPM (revolution per minute). A higher spinning speed means better blade sharpening and better grass cutting. Most powered blades sharpeners come with a speed of 1500-2000 RPM.
Material and Durability
Look for a durable sharpener, carbide is more durable than stone and lasts longer than other materials. If you can get a warranty on the blade sharper, it adds value to your purchase.
Safety
The blade should be safe. Look for additional safety features like blade covers. Always take the necessary safety precautions while working with such machines like safety gloves, safety goggles, work boots, and safety clothing. Do not let children get near your working space.
Ease of Use
Along being safe, your sharpener must be easy to use. Look for factors that make it user-friendly.
