Are Lawn Mower Blades Universal?

Are Lawn Mower Blades universal

The most straightforward answer is no. Manufacturers make lawnmower blades according to different specifications, which means each lawn mower model has its customized blade.

As much as you want lawn mower blades to be universal, sadly, they are not made general to every lawn mower present in every home.

Even when mower blades are not universal, you can still replace your lawnmower blade with another manufacturer’s blade, so long as the blade matches the required width, thickness, and much more specific customization that your original blade has.

Lawn mower blades are mower-specific, so if you think of replacing them with a new blade brand, ensure it’s the perfect fit for your mower to keep you away from danger while in use.

Types and Uses of Lawn Mower Blades

Reel blades

The reel blades, also known as cylinder blades, comprise seven helical blades that create cutting action like scissors. These blades are used in reel or cylindrical mowers, and they require sharpening tools if ever blades become rusty or dull.

Reel blades move in the opposite direction of the bed knife, which gathers the grass and cuts them as it moves across the bed knife cutting edge.

Mulching blades

From the name itself, these blades mulch the grass on your lawn. The mulching blade has a more distinct design than the other blades since it does more work.

This blade is known as an all-purpose blade because it features a curved or bent surface that allows the mower to work in three different ways: either lift, mow or mulch the grass, which operates the way people want to work.

The middle part of the mulching blade has a weird cut, but this cut allows your mower to deliver fine cut and nutrient-rich clippings back to the surface of your lawn to feed the soil healthily.

Deck blades

Deck blades are also known as the standard blades, and these blades probably get the most uses when it comes to lawn mowing.

These blades are referred to as straight blades because they do not cause strain on the engine during use.

The front cutting blade remains flat in view, and the back portion has a slight bend or curve that contributes to the suck and cut action of the mower.

Lifting blades

Lifting blades have a slightly curved surface creating a vertical upward airflow, which contributes to lifting the grass, allowing you to cut them depending on which type of lifting blade you want.

These blades render a more neat and polished result in cutting grasses than any other blade type.

There are three different types of lifting blades: low-lift, medium-lift, and high-lift blades.

  • Low-lift blades

A lifting blade with just enough power in providing lift to cut your grass is the low-lift blade.

These blades have just the right amount of cutting ability, but these do not suit thick grass on your lawn.

They won’t do as much trimming or cutting thick grass, but they won’t kick up as much dust.

This is a low-powered lifting blade that can be your friend if you only want a gentle movement to cut your grass.

  • Medium-lift blades

The medium-lift blades are medium-powered blades that provide the right suction amount compared to the low-lift blades.

These are much less mild than the low-lift blades, which means you can have this lifting blade if you want a bit more power when cutting the grass.

The medium-lift blades use less horsepower than the higher ones, and they can help you cut thick grass on your lawn.

  • High-lift blades

The high-lift blades provide the highest power of suction compared to the other lifting blades.

These blades offer more climactic upturn when suctioning before cutting the grass, producing much more lift. These blades can be your best help if you deal with thick grass as this makes the job a lot easier and time-saving. 

This blade is the best for tall grass and fits bagging up clippings.

Final Words

Now that you know about lawn mower blades not being a “universal” use, it is safe to say that you are now aware of what type your blades are and which blades fit for your mower.

Each blade is made uniquely specified for the mowers, so never attempt to use blades of different sizes and specifications on your chosen lawn mower.

Yes, some blades have your desirable blade type, but you’d instead choose the most suitable blade for your mower over something you only want, personally.

If you change your lawnmower blades with those still suited for their size and work, you will achieve the best results in keeping your lawn clean and grass healthy.
