Best Lawn Mower Blade Sharpeners.

A mower blade cannot do without its sharpness, the center of its cutting power. Without sharpness, they lose their cutting power and instead end up destroying whatever it is they were meant to mow.

How does the destruction occur? Instead of cutting through the grass, they tear it up leaving behind serrated edges that weaken the plant. Then instead of attractive beautiful grass, your lawn becomes home to brownish or yellowish looking grass. In short, a dull blade will hurt your lawn.

A lawnmower blade becoming blunt never happens overnight but is a gradual process especially if you use it frequently or for heavy commercial purposes. Blade sharpeners were invented to be a solution to this problem.

We have compiled a list of the best lawn mower blade sharpeners because sharpening is already heavy a task, so allow us quickly run you through some of the options available.

Choosing the Best Lawn Mower Blade Sharpeners

Here are some guiding points elaborating on the details to look for in lawn mower blade sharpeners

Spinning Speed

How much time are you willing to spend sharpening? Manual sharpeners take more time before you can get a good edge. If you go the electric way you can save on time better than with the manual option. Electric sharpeners rely on rotations per minute and horsepower to deliver the desired edge. Be careful not to mistake speed for efficiency because it could result in the destruction of the blade through overheating and could even hurt you. Always find a sharpener whose speed matches your blade.

Power Type

Preferences will differ so you may find yourself choosing a manual blade sharpener over an electric or vice versa. Manual sharpeners are very affordable but will require a lot of your input. Electric ones on the other hand may be of higher price and will require little effort on your part.

Quality and Durability

Quality and longevity of use will always be among the major factors in any purchasing decision. The two factors intertwine a lot therefore high-quality material on a sharpener should top your list if it is to be used for a long period.

Safety

A lot of friction is involved in blade sharpening and some sparks may escape once in a while. Is the blade sharpener you are getting providing safety against these? If not then you might want to consider changing to a safer option. Like the handheld grinders that often have finger guards. Alternatively, you can purchase safety gear like gloves, non-flammable clothes, and eye protection as well.

Versatility

Best lawn mower blade sharpeners are not restricted to sharpening a single blade. The more it can handle the better. This is a money saver when you own different types of blades. Remember also that some sharpeners are good on large blades but can easily destroy smaller ones. Others can do a mulching blade well but do not affect a standard one. Keeping this in mind will save you in the long run.

Guide Material

This refers to the guide that directs the angle at which sharpening occurs. This helps keep the blade incorrect position. Most are made of plastic which if mishandled come apart easily. Before making a purchase ensure the guide is strong enough to handle the pressure that comes with sharpening. Also, check to be certain that the plastic is not the one that overheats or even melts during sharpening.

Warranty

For your peace of mind consider getting a sharpener with a warranty. Some encompass a return policy in case of dissatisfaction with good reasons. This is one of the ways manufacturers guarantee the quality and durability of items.

Best Lawn Mower Blade Sharpeners FAQs

Q: How to Use a Lawn Mower Blade Sharpener?

A: Step1: Disconnect the plug for corded mowers or detach the batteries for the cordless ones. This helps prevent the engine from starting when your hands are on the blade area. Tip the mower to the side. Uninstall the blade and note how it came off so you can have an easy time putting it back. Marking the top or bottom can make it easier to identify the parts during reinstallation. Clean up the area in case of any stuck dirt or clippings.

Step 2: Put on protective gear then using a vise grip clamp it in position ensuring that the cutting surface is facing upwards. You can now start sharpening.

Step 3: Balance the blade. This ensures all the parts of the blade get sharpened evenly. Uneven sharpening results in one side becoming thinner than the other eventually ruining the blade and even the mower. If there is a slight difference during sharpening try and even it out.

Step 4: Reinstall the blade and reconnect any parts like the plug.

Step 5: Get back to mowing!

Q: How Sharp Should a Lawn Mower Blade be?

A: A well-balanced lawn mower blade in terms of sharpness is what you desire to have. That is not too sharp to cause chipping or rollover in the deck and not too dull to destroy the lawn.

Q: Do I Need to Sharpen a New Lawn Mower Blade?

A: It is often unnecessary but some lawnmower blades come coated causing interference with their sharpness and may call for sharpening before you can use them. usually, it is good practice to first install and mow a little part and see how the blade performs so you can decide whether it is deserving of sharpening or not.
