You should focus on the power source

Electric lawn mowers are environmentally friendly. If you have a lovely small garden, this will be the best choice. Moreover, it’s cheap and easy to store. An electric mower costs about $60. It needs a cable to run, so it’s suitable for a large garden.

Choosing the width blade deck is a should
