Sharpening Speed

The speed of your lawn mower blade sharpener is one of the most vital things to consider before making your choice. Ideally, the speed of the grinder should be related to the edge you are working on. You do not want a very fast grinder, as it is not always the best. It could cause overheating and excessive vibration, which could fall and hit your leg.


It is equally important to consider the safety of your lawn mower blade sharpener before making a choice. When sharpening, excessive speed could result in friction, which could trigger injury. In addition, the sharpener should be mounted on a rigid surface with a limited tendency to fall.

Quality and Design

It is important to note that quality is the most vital thing to consider in choosing a lawn mower blade sharpener. In addition, a higher price does not necessarily translate to a better quality. Thankfully, the majority of the lawn mower sharpener we reviewed in this article is less than $25.

Best Lawn Mower Blade Sharpener: FAQ

We thought to explore some questions users might have on the best lawn mower blade sharpener. We hope it might answer some of the concerns you might have. A few of these are:

Q: What Should be the angle of a Sharp Mower Blade?

It is important to be mindful of the original angle of your mower blade before sharpening. This is important to guide you to prevent the performance from being affected. You should not file the bottom surface of the file to prevent altering the sharpening angle.

File only the top angle and work with an angle of 40 to 45 degrees. This is the most common angle for blade sharpener.

Q: How often Should You Sharpen Your Lawn Mower Blade?

There is no definite answer to this as the frequency of sharpening your lawn mower blade is a factor of how you use the lawn mower. If you use the lawn mower at home only, it is enough to sharpen the blade once a year. This is, however, different if you use the mower for business or quite often. You might have to sharpen it more often.

Ideally, be on the watch out for the reduced performance of the mower. This could be a sign that you need to sharpen the blade. In addition, watch out for a damaged blade as well. You will have to replace such.

Q: How Tights Should the Blades be?

On tightening the mower blades, it is also important to have them installed correctly on the lawn mower. This is a very important process as if you do not get it right, it might lead to unnecessary injury.

When it comes to the tightness of the mower blade, the blades should be installed between 70 and 90 foot pounds of the torque. We recommend between 38 and 50 foot pounds of the torque for installation of walk behind mower blades.

Q: Can a Power Drill Sharpen my Mower Blade?

A power drill alongside a grinding stone is part of the most important accessories you will need when sharpening your lawn mower blade.

All you need to do is power the drill and run it on the dull blade with the sharpener attached. While there is no set time on the frequency of sharpening the blade, it is a matter of usage time.

Sharpen your blade every month if you are a heavy user. You will reduce the chances of having a dull blade and increase effectiveness.

Q: How Sharp Should the Mower Blade be?

The blades of your lawn mower should be sharp enough to handle all your cutting needs. While it should be aggressively sharp, a razor-sharp blade is not recommended. In other words, you should be able to touch the lawn mower blade without getting injured.

A razor-sharp mower blade edge might gradually chip off the blades. Also, it increases the tendency of the blades becoming dull. This decreases the overall life expectancy of the blade.
