Electric starter

The presence of an electric starter in a gasoline or diesel lawnmower engine (see "Engine type")

Such a system is an electric motor powered by a separate battery. It greatly simplifies the starting procedure: no need to pull the cord or turn the handle — the rotation of the shaft necessary for starting is provided by an electric motor. In essence, the user only needs to press a button. On the other hand, electric starters are rather heavy, bulky and expensive, and the battery can be discharged during long-term storage. Therefore, this function is found mainly in high power motors, which would be difficult to start manually.
