Best Lawn Mower Blades
When it comes to lawn mower blades, the brand does not always matter, but the most important thing is that it is a type of blade suitable for the machine you have. If you buy a smaller one, or a very large one, it will simply not be useful to you.
Therefore, before choosing a lawn mower blade, you should check which one you already have. Once you know the model of your lawn mower blade, you can buy the one that is best in its style.
With that being said, we’ll recommend a few blade styles for you to consider, mostly based on the type of grass you need to cut. That’s another factor you have to take into account: how big the field is, what type of grass it is, etc.
If you have hard grass, then it is recommended that you buy gator blades or shredding blades. This type of blade is prepared to cut on hard grass without any problems. For this same reason, you should be extremely careful to avoid cutting other things.
It can happen that if these blades run into stones they break them, and the pieces of the stones are thrown to any side which can be dangerous if they go in your direction. Remember that the lower power cutters are not prepared to support the weight of a shredder blade, so if you need one you should buy a machine that can support that type of weight.
If you have a regular type of grass, which is what is found naturally in areas with a temperate climate, then the low lift blades or standard blades are perfect for you.
If you have to cut the grass and it has grown a lot, then you should go for high lift blades. These types of blades are used to cut long grasses without any problem.
Keep in mind that at the end of the day the most important thing is that the blades are sharp. If they have the right edge then they can be used practically on any type of grass, even if they are better on a certain type.
How To Replace A Lawn Mower Blade?
Some people think that to replace lawn mower blades you need to take them to a technician or let a professional take care of them. Although this is a good idea in case you don’t feel safe doing it, the truth is that you can also do it yourself without any problem.
First of all, it is always recommended that you wear some kind of protective gloves. These gloves should protect your hands, but they should also allow you to move your fingers without a problem.
Once you have your safety geared up, it’s time to get down to business. You must remove the retaining screw, it is recommended to block the blade with a board, this way you prevent it from coming loose and hurting you.
Once the screw is out and the blade is loose, you can carefully remove it. There you can determine if it needs to be changed completely or if you can fix everything by sharpening it.
Once you determine this, all you have to do is make the change and put the new blade on the mower. It is important that if you buy a new one it has the exact measurements, otherwise, you can run the risk of breaking your machine while trying to put it on.
Finally, put the screw and make sure to give it all the necessary turns so that it is correctly hooked on the machine. It is very important that you make sure that the screw is properly tightened, otherwise, you run the risk of the blade flying off while cutting the grass.
How To Know If The Mower Blade Is Upside Down?
To know if the blade is upside down, the first thing you should do is know which side is correct. You can tell this by looking at which is the cutting and sharp edge, differentiating it from the side that is blunt. Some blades come with labels that help you know which side is up and which is down.
If they don’t, then you should know that the cutting edge should face the grass, while the blunt edge should face the “inside” of the mower.
It is important that you make sure that it is on the correct side before using the lawn mower, since you can damage the machine if you use it incorrectly, and it will also not work to cut the grass.
How To Balance Lawn Mower Blades?
Lawn mower blades can become unbalanced if you sharpen them unevenly. This means it is not done uniformly so there is one side that is thicker, and consequently, heavier than the other. This causes a lack of balance and that is what makes the blade lean more to one side than the other.
It is always essential to check the balance of a blade before replacing it, so as not to put your mower or your safety at risk.
To check if you can drive a nail into a wooden plank and balance the mower blade on the end of this nail by putting the hole in the center of the blade over the nail head.
Then you need to turn the blade and release it. If it stays in place, that’s a good sign. If it continues to move and leans to one side then this means it is not balanced.
Look at which side it tilts, so you can know which one has a problem (since it is the heaviest). You can sharpen that side until it is the same weight, and so your blade is back in balance. Or you can take it to a specialist to fix it for you.
How Often Should Blades Be Sharpened?
Although this depends on each blade, there are certain average numbers to know how long you should wait to sharpen your blade. On average, a lawn mower blade should be sharpened after every 20 to 25 hours of use.
Of course, this can vary depending on how often you mow, how long the mowing lasts, and the most important factor is the type of grass. There are longer grasses that practically ruin your blade with a single cut. Or if you cut the grass when it’s damp or wet this also dulls the blade faster.
New lawn mower blades do not need to be sharpened because they are always sharpened during manufacture. However, lawn mower blades generally need to be sharpened at the start of each new season.
How Often Should The Blades Be Changed For New Ones?
It is always recommended to have your lawn mower blades changed annually. If the blade continues to cut grass effectively, once a year is a good amount of time, but there are several factors that can affect this.
You may need to replace the blades sooner if they become damaged. It is always important to make sure you take protective measures whenever you have to sharpen or change your lawn mower blades at home.
As we said before, if you don’t feel comfortable doing it yourself, you can take it to a technician without any problem and they will complete the job right away.
