Which Features to Check in a Mower Blade?

Buying a replacement mower blade is easy if you know what to look for. You need to understand the basic features of the blades and some of these include:

• Length of the blade
• Build material
• Deck size

Length of the blade 

The length is the first thing you need to check before buying a blade. This way you’ll know exactly what you need and whether the blade can fit in your lawn mower. The average size range of mower blades goes from 16.75-inches to 22-inches and our article reviews these different sizes, so we’re certain you can find what you need. Make your decision based on the mower model.

Build material

The choice of the build material doesn’t depend on the model of the lawn mower you have. Most blades are made of metal and you should purchase good quality metal that can last for years. This isn’t something to compromise on, because the lesser the quality of the metal the more difficulties you’ll have maintaining your lawn. Mower blades are a long-term investment, so even if you chip in more it’s worth the while.

Deck size

Deck sizes in blades can vary between 16-inches to 30-inches and you can easily check this from the specifications of the blade.

It’s good to know the type of mower blades to get the one you need. Some of the most common types include:

• Cylinder or reel blades
• Deck blades
• Mulching blades
• Lifting blades

Lifting blades are further divided into low-lift, medium-lift, and high-lift blade.

When to Sharpen My Mower Blades?

Sharpening your mower blades is essential in their upkeep. Ideally, you’ll need to sharpen them every few months in the season and this can greatly depend on how much you use them as well as the size of the lawn.

Depending on this, you might need to sharpen the blades only once in n a year. There isn’t a strict rule about this, but you must watch out for the performance. If the blade isn’t cutting the grass as it should, then it’s time for a change.

Changing a damaged or worn-out blade on time is important for the overall condition of the mower as well as the health and growth of the lawn grass. Also, damaged, and dull blades can cause damage and injuries if not replaced on time.

Although you might want to get the most out of your blades have in mind that these are expendable tools and won’t last forever.

Proper maintenance is key.

How to Sharpen Lawn Mower Blades?

There’s not much choice when it comes to blade sharpening. If you have the tools and know-how to do it, you can sharpen them on your own or go to a professional shop and get them sharpened.

Have in mind that most new replacement blades, like the ones we reviewed, have a protective coating that shouldn’t be removed by sharpening. After a few cuttings, the coating will wear off on its own.

How to Replace a Blade?

Replacing a blade might not be intuitive to everyone and most of the blades don’t come with instructions to help you through the process.

You just need to go with the flow and figure out on your own; be extremely careful when doing this and make sure you have the mower turned off before adjusting anything on it.

When working with sharp tools, don’t forget to wear protective equipment such as a pair of gloves that can protect your hands.

Which Blade Fits My Lawn Mower?

When it comes to buying replacement blades, make sure you consult the instruction manual for your mower and get the needed information there.

You’ll need to check the center hole on the blade which can be star-shaped or circular and these two shapes represent different types of blades altogether.

How to Clean the Lawn Mower Blade?

Proper blade maintenance includes regular cleaning. The combination of proper use and maintenance can prolong the life of the blade and improve its performance.

It’s recommended that you remove your blade from time to time and check it for any damages and clean it.

Obviously, you can use your garden hose to clean it off and remove any leftover clippings. If you want to remove residue or muck you can use a wire brush and scrape it off.

To finish off, coat the mower blade with lubricating oil, put it back in the mower and it’s ready for your next mowing session.
