Is it possible to mow wet grass with a trimmer and lawn mower and how to do it?

Arrangement of a suburban area (and even a local area in the city) is a very complicated matter. Especially because you have to take care of the household all the time. Many people have questions about how to do this or that job, for example, is it possible to mow wet grass with a trimmer.

Features of the situation

Of course, such a question does not arise for those who live in the immediate vicinity of the lawn. Then you can wait a while, and work when the grass dries. But the need to clean wet grass arises immediately if you can visit the site only occasionally. What to do if you have to mow the lawn at the weekend, on another day with rainy weather, that’s the subtlety. The opinions of the summer residents themselves differ, therefore focus on their position does not make much sense. You need to understand the nuances yourself.

Equipment role

From the very beginning, it must be pointed out that there are two main types of trimmers, which in different ways “relate” to wet vegetation. Some devices are equipped with a gasoline engine, while others are driven by connecting to the mains or installing a battery. In turn, electric mowers are divided into two subgroups: with the location of the motor in the lower or upper part of the apparatus. It is safe enough for the user to remove wet grass can only petrol trimmers or hand braids.

Using an electric mower in this case is categorically undesirable. Sometimes you can come across allegations that this requirement applies only to devices with a lower motor placement. Such an electric motor comes into direct contact with water. Due to this contact, short circuits can be feared.

However, you should not use an electric mower with an overhead engine after rain.

If water does get inside the power plant, there is a risk of not only a short circuit, but also an electric shock. It is worth noting that these restrictions apply not only to trimmers, but also to full-fledged lawn mowers. The assurances of manufacturers and marketers about security should not be taken into account. To minimize the risk for yourself and your equipment, you should use a lawn mower. But there are a few more subtleties that must be taken into account.

Even if the mowing machine does not fail, and its owner is not shocked (let’s say such a favorable situation for a minute), you still cannot mow the raw grass with a trimmer. This is a known abnormal mode of operation, due to which the equipment wears out too quickly. Wet vegetation has a much greater resistance to cutting elements than it should be. Therefore, even very well insulated motors operate with overload.

Due to the sticking of wet grass to the knives and the spindle, the load on them will necessarily increase. This can not be avoided, and no skill kosets, no methods and schemes for clearing the lawn do not help. Not only the motor suffers, but also the shaft, which sometimes cranks.

Problems with mowing wet grass can occur in gasoline devices. Yes, they are more powerful than electrical counterparts, but the load is still higher than normal. First of all, “under the blow” are piston pairs and other moving parts. If there is no way out other than using a gas mower, you must protect it. When mowing raw grass, the device is periodically switched to idle without load. 30 seconds is enough to remove excess heat, as well as save the life of the trimmer.

And about different situations

When talking about mowing wet grass, you need to distinguish the following possible situations:

  • it is wet after rain;
  • it’s raining;
  • the cause of moisture is a moist area (lowland or soil water).

In the first case, it is quite possible to take a chance and try to clean up the lawn mower. In the second mowing is impractical. In the third, you will first have to decide something with humidity and only then put the lawn or lawn in order. If you often have to mow wet grass after rain or "in the dew" in a small area, it is better to use not a trimmer, and not a lawn mower, but a simple hand-held scythe. You need to look not only at the grass that is being cleaned, but also at the one where the network wire is laid.

Moisturizing it can be a very serious risk factor. To mow grass after rain, you need to wait a bit. A few minutes, even with a very large hurry, will not noticeably reduce the time that can be allocated for mowing.

And the result may be clearly better. Mowing grass along dew, even with an electric lawn mower or trimmer, is usually permitted.
