What to look for when buying the best lawn mower blades? 

Now that you have checked out the best lawn mower blades that are available in the market, let us take a look at the different aspects that you should consider before settling on one. Not all mower blades are made equal and different blades are suited for different uses. Knowing what works for you is essential if you want to get a product that is not only compatible with your needs but also your lawn mower itself.

Just figure out what features are the most crucial to you:

Blade Lift


The lift of a blade will determine how it cuts the grass and how much area it can cover at a time. There are three different blade lifts that we will go through, namely – low lift, medium lift, and high lift.


Low Lift


These blades are mainly suited for residential purposes. These blades usually are not found on professional-grade lawnmowers since they are shorter in size. Though they may not cover a lot of area, they do get the job done without much hassle for a small mower used on a small lawn.


Medium Lift


These blades are much bigger compared to low lift blades and can do much more. They can even pluck out thicker grass and even weeds from your lawn. Since they are capable of cutting large and small grass alike, these blades are used both for residential and commercial purposes.


These are also the most standard blades that you will find in the market. It is the ideal option for people with larger lawns since it strikes a great balance in terms of size. It is much stronger than a low lift blade but not too harsh that it would eat at your lawn the way high lift lawns do.


High Lift


If you have grass that grows too fast or if it is too thick, then you should be looking for blades with a high lift. These blades can clear away much more in one single sweep and clear out grass of all types from your lawn.


It is way stronger and bigger than its counterparts and work for long periods of time. It is also a time saver since it can do much more in a short span of time. For all commercial lawn work, this is the type of blade that you should be looking for.


Blade Mount


Mounts are the center holes that are found in blades. These are also quite important when you are looking for best lawn mower blades. There are various different kinds of holes that you will find on mower blades and each of them have a unique purpose of connection with spindles. There are many shapes including circular, rectangular and star-shaped mounts. Of these, the point star shapes are the most common and are further available in 5-point, 6-point, and 7-point star mounts.


Mulching Blade


Also known as a gator blade, these are much favored by designers and veteran gardeners. The mulching blades are much more interesting in the way they handle grass clippings. Mulching blades cut grass so fine that you won’t need to dispose it off since it is thrown over the grass as fertilizer.


The cuts that a mulcher provides can vary and allow for professionals to have their own creative touch on their lawns. These blades are used for aesthetic purposes since they can change the appearance of lawns, parks, and gardens.


These best lawn mower blades also come in different blade lifts and can be used for residential lawns just fine, and are beneficial for your gardens as well.


Length and Width


This aspect can be quite tricky to consider since you can only get a rough gauge of how long and wide the blades need to be to fit into your mower. The length of the blades cannot be too long or it may be difficult to manage. Or if it’s too short, it won’t allow you to cover enough lawn area. You need to find the exact balance between the two.


Similarly, the width can be a hassle as well since you may not be sure of the mower’s measurements that should be compatible with the blades. Therefore, it is paramount that you get some measurements of your mower and that should guide your decision when choosing the best lawn mower blades.


Tilt Degree


You should get a good idea of the blade’s tilt degree since that can make a big difference in how you operate, cut, and bag the grass clippings. Usually, the higher tilt degree there is, the easier it will be for the grass clippings to be bagged into the container so you won’t have to worry about cleaning up after you are done which saves a lot of time. However, if you want to leave the clippings as fertilizer then a low tilt blade is a better option for you.


Thickness


As is usually the case, the thicker the blades, the more powerful and efficient they are going to be in terms of cutting through large areas of the lawn in a relatively short amount of time. At the same time, thicker blades can also be harder to handle which can be a problem for the user.


On the other side, thinner blades allow you to get much more refined cuts since they are easier to operate. However, it can take a lot of time to go through a huge yard with them. Ultimately, your needs should dictate which blade type should purchase to make your mowing experience pleasant.
