Many problems can occur with the lawnmower during use. And the fact that the lawnmower suddenly loses power when the saw blade is operating is one of those problems.

Regardless of the lawnmower, this problem cannot be avoided during the operation of even the most modern machines.

Not only affects the cooling system, but the dirt on the machine also affects the carburetor. If not carefully checked, it is easy to accumulate dirt and water here. This makes the process of burning fuel operate less efficiently. Then the motor stops automatically and does not continue.

2. The operating capacity of the machine

Depending on the terrain, there will be suitable lawnmowers. There will also be machines that can operate stably on many terrains.
