If you are a house owner, then a lawnmower is a must for you to keep your yard adequately maintained. Cutting your lawn’s grass makes it look neat and clean.

However, you have to choose a lawnmower based on what look you want to give to your yard. But the crucial part of buying a lawnmower is having a decent knowledge regarding the different types of lawnmower blades.

Lawnmower blades are the cutting component of mowers.

Below we have provided all the information concerning lawn mower blades, including their advantages and disadvantages.

Do Different Types of Lawn Mower Blades Have Different Dimensions?

Yes. Each lawn mower blade can be different when it comes to shape, length, measurements, and the type of mounts.

So, you can say that every individual blade will not be able to be attached to every type of lawnmower.

The variation of dimension is essential when we are talking about lawnmower blades.

5 Types of Lawn Mower Blades Explained

Standard or Deck Blade

These blades are typically used in standard lawnmowers. And these blades usually rotates horizontally.

Standard or deck blades are also known as straight mowers blades. If you own a lawnmower that discharges the grass debris sideways, you can equip this type of blade.

Moreover, these blades tend to have a slight curve on each edge. This feature generates a continuous airflow when the blade rotates. That’s how it creates sucking and cutting action.

Most people choose this kind of blade due to its high performance on both dry and damp surfaces.

However, our suggestion is to use this blade only if your yard has thick patches of grass. This kind of blade can cut your yard’s dense grass very swiftly and send them to the bagging very quickly.

If your yard has light grass all over, then this type of blade may not be able to remove the smaller clumps of grass. This may leave you with an irregular lawn.

Reel or Cylinder Blade

This kind of blades feature between 3 to 7 screw-like blades and are used in cylinder or reel lawnmowers.

These blades generate a scissor-like movement while mowing as they are connected in a horizontally rotating cylinder.

Moreover, these kinds of blades have a helical shape and cut the grasses just like a scissor cutting a paper.

The process of cutting the grass is unique to this blade. It cut grass by trapping them between sharp rotating blades and stationary bottom blades.

Lifting Blades

For being prepared with a curved surface lawnmower, these blades can create a steep flow of air. This flow of air is essential in moving the grass up.

And most importantly, this rising of grass will make sure you get a smooth yard that you may not get from other types of blades.

However, you will find three types of lifting blades. They are classified by the angle of the lift or curvature.

Low Lifting Blades

From the name, we can say that this blade provides the lowest suction power. Specifically, it does not have more than ¾ inch blade lift and 3-4 inches in length.

However, this low lift blade is very advantageous for cutting small and dry lawns in sandy and dusty terrain.

The side discharging characteristics make them ideal for cutting your grass efficiently and allows you to keep the amount of dust, noise, and debris very low.

Medium Lifting Blades

Generally, these blades have a lifting range of approximately ¾ to 15/16 inches.

It creates quite a good amount of airflow, which helps them to cut grass of different sized lawns.

High Lifting Blades

No other lifting blades can generate as much suction power as the high lifting blades. These blades have a lifting range of 1 to 3/16 inch and 1-21 inches in length.

These high lifting blades are efficient in collecting grass clipping. For that reason, these blades are mostly used in collecting and bagging.

You do not like to use these blades on sandy or dusty terrain as the dust and sand can quickly wear them out too early.

3 in 1 Gator Blades

These blades tend to have several characteristics. It is considered as an all-rounder solution for covering all the bases with it’s 3 in 1 feature.

Moreover, you can use it for mulching, bagging, and side discharging.

In fact, these blades have a very uncommon design where the curved part is cut into several teeth.

These teeth are used to push the grass clipping into the centre of the blade where the grass is cut into smaller pieces.

Additionally, the serrated part of the blade is designed to have a bigger curve. This assists in better suction and lifting of the grass.

Mulching Blades

The design of these blades is very unlike the other different types of lawnmower blades.

The blades tend to have a wider cutting edge and a distinct curvature. This curvature allows it to function in three ways,

Lifting process – Firstly, these blades start by dragging the grass upward and cutting it.

Mowing process – To cut the grass into small pieces, the grass clippings are pulled inside the deck.

Mulching process – The innermost curvature of these blades produces pressurized air to cut the clipping by force.

You can use these blades for mulching, discharging, or bagging the grass clips. Most importantly, for having more curves, the surface area of the cutting edge is greater than the others.

The larger surface area of the cutting edge allows the grass to cut several times before bagging and discharging.
