How to Choose a Lawn Mower Knife?

Caring for the lawn is a necessity that is simply impossible to avoid. However, this is correct, since a beautiful lawn is the face of the owner of the house, which means that it shows you only from the best side. But do not forget that you need to take care not only of the grass, but also of the tool itself. And it’s absolutely unimportant here whether you cut the lawn with a lawn mow or lawn mower, cut it with a mini-tractor or use the services of a modern robot. But what is there, even the ancient braid needs sharpening! What to say about more modern devices.

What do you need to take care of first?

Of course, your attention requires a fairly large number of things, but some of them are more important than others. The most important is the lawn mower knife. This attitude is justified, since with a blunted blade it is impossible to achieve a high-quality cutting.

If we talk about bent or damaged devices, then this can lead to a number of consequences, where one of the easiest is a complete breakdown of the device. As examples of the most dangerous results of such indiscretion are cases of severe injuries during mowing.

In addition, you definitely need to check the engine from time to time. All work is based on it. So you should not neglect technical inspection, even if time is sorely lacking.

If you are using a lawn mower, then there are other problems. A knife for a gas lawn mower can be put on one step with the wheels. Such a base for movement plays an important role. If something breaks right during the movement, then subsequent damage can affect the more fragile internal parts of the machine.

Which cutting tool can be replaced?

If you use various mechanical devices for grass care, you should know that as a cutting tool not only a lawn mower knife can be used, but also a trimmer line, or, as it is also called, cord.

If we talk about the first separately, then a little emphasis needs to be made on the second. The trimmer line can vary in thickness as well as in shape. These two aspects are very important to consider. In addition, there are still differences in materials. This is especially important for woods from Chinese manufacturers. However, it is better to acquire exclusively European brands in general. Its own security is more important.

Lawn mower knife

The choice of cutting blade for a lawn mower depends on several factors.

Such data is usually indicated in the technical specifications of the purchased machine. However, the use of a slightly shorter knife will not lead to terrible consequences. Unless the process itself will take a little longer, and the missed sections will be not uncommon, but commonplace.

The brand

Do not forget that all manufacturers of lawn mowers use individual mounts for cutting surfaces. The safest thing for you will be a replacement for the same brand, or even a model. For example, an Al-Ko lawnmower knife is only suitable for this brand and so on.

If you make a mistake in the choice, this will lead only to one thing. You cannot connect the knife to the machine. But in the event that you succeed, it will only get worse. During operation, such a blade will be very unstable, since it will not be fastened at all as it should, which means that the quality will become much worse than it should be. But these are only flowers. Berries will go when the blade flies out of the socket. And this could very well happen, because unreliable fastening plus fast turns. In general, physics will do everything as it needs. Subsequently, either your lawnmower or you yourself will be injured. A combined option is not excluded.

However, there are other possibilities besides buying the exact same cutting mechanism as the one that stood on your typewriter before. We will discuss them below.

Using adapters

They use it to connect the engine with a knife, and it performs the following functions: firstly, it makes it possible to use almost any blade with each engine, which is produced in series. It does not damage the engine. If the load exceeds the permissible limit, then the adapter, along with the cutting surface, will simply fail, thereby saving the motor. Sometimes it also acts as a wheel drive belt pulley.

Adapters can be very different, since each manufacturer needs its own mount. Despite this, finding the right one is not difficult. Even the largest brands have no more than a couple dozen such devices in production. The rest, indicated as possible, are simply no longer available, although they can be used.

Universal knives

There is another option for replacement. It’s still quite difficult to find a specific model. That is why universal mowing knives are firmly included in the sale. Their peculiarity is that they can be fixed in several ways, which makes work safe on many lawn mowers at once.

Also, such devices are usually equipped with a whole set of washers and adapters, which allow them to be securely fixed on machines of most brands.

Electric models

So-called cutting devices for trimmers. Actually, electric knives for lawn mowers are disks of the most diverse shapes, although there are more interesting options for an outside observer.

They are used in this way. They are inserted into the head of the trimmer, fixed, and then it’s a matter of technology and time.

Such knives are made mainly of plastic. This is most likely due to the safety of the user, since the metal disc can be thrown back, which cannot be allowed on braids with a curved bar. If your lawn mow is equipped with a direct barbell, then you can use iron discs. With their help, you can mow anything. From grass to shrubs or even young trees. However, such units also have drawbacks. If you stumble upon a stone, the disk will simply flatten. This is not because the metal is of poor quality, but to protect the entire trimmer from breaking.

In conclusion

You should remember that buying any cutting mechanisms is only in reliable places.

Before making a purchase, read the instructions and technical specifications of your lawn mower.
