Above are pictures of a Greenworks mower after two seasons. The mower came in for making noise. You can see how the motor is clogged with grass on the left side motor, the right side motor is after cleaning and replacing the bearings
Electric mower also need service , just because they run on batteries or 120 volt doesn't mean they will not need yearly maintenance, see the pictures below for more information.
This is another reason for yearly service. We remove the top cover of your equipment and clean it out. This can cause the motor to overheat and fail.
This is the motor pulled apart for cleaning and a rebuild. A new motor is about $90 if we had to replace it. This mower had two.
Don't forget blades also have to be sharpened.
