Why Sharpen your Mower Blades?

A blunt mower blade pulls and rips the grass blades, causing ragged tears that enhance fungal growth and weaken the plant. However, a sharp blade cuts clean, giving the plant a chance to heal quickly. A sharp lawnmower blade also helps you to complete your cutting tasks faster and without straining.

FAQs

What is the Best Lawn Mower Blade sharpener?

All the reviewed products below are among the fastest sharpeners in the market and offer a fast and effective sharpening solution out there.

Is it Worth Sharpening Lawn Mower Blades?

Absolutely! Sharpening the mower’s blade is not only worth it, but it’s a must. Dull blades will damage your grass and leave uneven grass patches. As a result, your grass turns brown and becomes more vulnerable to diseases and pests. Sharpening the edges of your lawnmower will greatly reduce the time you spend mowing your yard.

After all, everybody wants to keep the lawn healthy and green, and a blunt lawnmower blade is among the things that can destroy a lush lawn. If you use a dull blade, the grass hairs will be damaged instead of being trimmed.

What is the Right Way to Sharpen a Lawn Mower Blade?

If you spot a piece of grass in your lawn that doesn’t have an even and clean-cut, this is a clear indication that your blade needs sharpening. First, disconnect the spark plug from the mower for safety precautions. Then, depending on the sharpener you have and the type of machine, you can either leave the blade in the mower or remove it. Lastly, wear your safety gloves and goggles and start moving the sharpener in small and gentle strokes. This process will take a couple of minutes.

What is the Best Angle to Sharpen a Lawnmower Blade?

The right way to sharpen a blade is to position your sharpener at a 45° angle. One of the most important stages in sharpening the mower blade is to use one direction. You should go back and forth when sharpening the blade. When you follow the right angle and the blade’s edge, you’ll easily cut out the missed spots.

Should I Sharpen Both Sides of a Lawn Mower Blade?

Normally, you should sharpen one side of the mower blade. Most landscaping enthusiasts don’t flip the blade to sharpen the other side, which can change the cutting height. However, you should never sharpen it fully.

Power Type

There are various kinds of mower sharpener options out there. This mainly includes manual blade sharpeners and powered ones.

It is crucial to go for a sharpener that has a secure attachment procedure but, most importantly, one that suits your needs. Check whether the tool is perfect for your dominant hand or can be used by any hand.

Spinning Speed

Check the spinning speed of the powered blade sharpener to determine its overall performance. A sharpener with a higher spinning speed has better performance while sharpening the blades. You can get options like 1500 or 1750 RPM spinning speeds; a higher RPM will result in better performance.
