The most important organ of any lawn mower is the engine. In the electrical unit, the motor runs on the mains, in the battery pack. The most popular mowers are equipped with gasoline internal combustion engines, which can be 2- or 4-stroke.
Each of them consists of many parts and mechanisms that are in a state of continuous friction. This leads to the heating of the elements and their rapid failure. It is precisely this problem that oil is designed to solve. Every owner of the lawn mower is required to know which oil is used for its purposes, correctly choose it, and fill it into the component.
