Do Brand New Lawn Mower Blades Need Sharpening

When changing the blades, you might wonder if they need sharpening because they often dont look that sharp at a glance. However, you will be glad to learn that you dont need to sharpen a new blade.

Most replacement blades have a powder-coated paint finish making them look thick at the cutting edge and less sharp to the touch. But they leave the manufacturing facility ready to start cutting. They apply the powder coat paint to the edge for the following reasons:

• It helps protect the blades edges from mechanical damage. The paint shields the angled side when it comes into contact with a hard surface before use or during installation.
• It makes sure you are protected from injuries, as the paint finish protects you from cuts when installing the blade. Even if you dont have protective gear, you are less likely to nick your fingers when replacing the blades.
• To prevent the blade from rusting as a long period usually passes between manufacturing and when you install it for use. Protecting it from moisture is paramount in preserving its integrity, and also, nobody wants to put a rusty part on their shiny mower.

You should also note that the powder-coated paint around the cutting edge starts to disappear after a few minutes or so of mowing.

Remove And Clean The Blade

Once youve determined that you need to sharpen the blade, its time to remove the blade from the lawn mower.

Before you begin, disconnect the power source from an electric mower, whether battery or corded. Disconnect the spark plug wire from a gas mower. This protects you from any surprise hiccups of power. Follow these steps to remove the lawn mower blade.

• Put on work gloves and protective eyewear for safety.
• Drain the gas tank to avoid fuel spills.
• Carefully turn the mower on its side. Be sure that the air filter and the carburetor are facing up.
• Find the nut that holds the mower blade to the drive shaft. Use a ratchet and socket or a wrench to loosen the nut until the mower blade releases.
• If its tough to grip the nut, get more leverage. Brace the blade with a piece of scrap wood and clamp the blade still. You should be able to remove the nut now.
• If the nut and threaded shaft are rusted or stuck together, apply penetrating oil and allow to sit for a few hours.
• Clean the blade with a dry rag or microfiber cloth before sharpening it.

Maxpower 331981b Universal 21

As the name indicates, it is a universal blade that can fit many mowers, including Husqvarna, John Deere, Troybilt, Craftsman, and MTD.

The best thing I observed about these blades is their lightweight 2 pounds only, which is comparatively less than other mulching blades. A lightweight profile helps the mower to rotate the blade fast and whip the grass into pieces.

Additionally, this blade has a greater cutting surface which means the sharp cutting teeth are extended in a way to produce the qualitative fertilizer called mulch.

It has a centrifugal airlift design which means the cutting edges are curved so that they produce suction, just like a vacuum pump. It means the suction will hold the grass up, and the rotating blade will hit it in the middle to cut it into small clippings.

You can observe the design in the picture below:

With a central hole of 1-inch and reducing washers that come with the blade, mounting this blade is damn easy.

It works equally on wet or dry grass, but it doesnt mean you should mow your lawn just after rain.

• It doesnt fit 21 inch Ego, Kobalt 80V, Honda HRR216, Ariens, Greenworks lawnmowers

Summary

This 21-inch mulching blade is a lightweight, sharp, easily installable, and durable blade. If you sum up all these features and finally decide to buy it for your mower, you wont regret it.
