Things to Consider Before Purchasing Lawn Mower Blades

First things first, you will need to consider just a few things before you go ahead and purchase lawn mower blades.

Rushing into it and choosing the first pair which looks attractive is not always the best option, just because you might end up paying more than necessary for an otherwise sub-par pair of blades, which might disappoint you in the end.

Granted, it will be time-consuming, but it will be worth it in the end. Here are the aspects to consider before purchasing lawn mower blades:

#1. Type Of Lawn Mower Blades

Not all lawn mower blades come in the same type, let alone function. In fact, there are a few, and we list them down below:


Standard Medium Lift

This particular lawn mower blade has a distinctive upward angle on the back edges for improved airflow.

It is also the best for getting a lot of lawn grass cut in a short amount of time, even though it might not be easy to bag up afterwards, due to its limited storage construction.


High Lift

On the other hand, high lift lawn mower blades have an even more drastic upward angle on the back edges, which actually allows for grass clippings to get funneled through the bag, thereby reducing clogging when it comes to cleaning up the area after a long day's’ worth of trimming.



This specific lawn mower blade has an elongated cutting edge, which allows for it to chop up the overgrown grass into small particles, thereby reducing clumps and the frustration it usually takes to bag them up afterwards.

You might also be surprised to learn that having this certain lawn mower blade can be beneficial to the overall growth of the grass, in that it leaves behind some grass clippings which give natural fertilizer to the ground, thereby cultivating the grass even more so.

If you intend to keep the grass growing and healthy, then the mulching lawn mower blade can be a solid option for you.

#2. Length And Width

These are probably the trickiest aspects to consider, since you will have to roughly gauge just how long and how big the lawn mower blades can fit into the machine itself.

For instance, the blades’ length should not be too long, or else it will be difficult to manage, nor should it be too short, since that would lead to less coverage of the lawn. Finding the right balance between the two lengths, then, is the way to go.​

On the other hand, width can be a hassle to go by, since you might not be sure of your machine’s measurements in order to fit the blades in.

That said, it is a good idea to take some measurements for your machine, and from there you can have a better idea of what to get for the blades themselves.

#3. Sharpness

Of course, you would like the sharpest possible blades for the cleanest and quickest cuts. However, it is also a matter of looking into just how you can sharpen them afterwards when they start to dull.

Perhaps also look into sharpening tools to help you out, and from there it can be a more worthwhile investment.

#4. Tilt Degree


As previously mentioned in the types of lawn mower blades, it is a good idea to consider the blades’ tilt degrees, for they can make a difference in just how you go about operating, cutting, and otherwise bagging the grass clippings afterwards.

​Usually, the higher the upward angle is, the more likely that grass clippings will be conveniently bagged into the container, so that you would not have to worry about cleaning it up after work, thereby saving you an extra step in the process.

However, if you intend on leaving some of the grass clippings on the lawn as a natural fertilizer, then using a lower-angled blade is the better option to consider.

#5. Thickness

Finally, it comes down to how thick you would like your lawn mower blades to be. Generally speaking, the thicker the blades are, the more powerful and efficient they are in terms of cutting through a larger area in a shorter amount of time.

However, if they are too thick, then they can be difficult to handle, which can pose a problem for the user.

On the flip side, a thinner blade can allow for more-refined cuts, should you desire just a light trim from time to time. In the end, it is up to you as to what you want and what you need to make your lawn-mowing experience a good one.​
