An electric tiller is a piece of machinery that uses power mains or a battery to run. They operate by pressing a start button which sends power to a set of tines (or blades) that rotate. The tines of electric tillers will churn and stir earth that has been previously worked on to create a softer soil with less density. Electric tillers have small, tight tines that break and loosen up the soil so you can plant seeds and bulbs easier into your land. An electric tiller is perfect for use on smaller gardens with medium hard soil - these are not used to create new garden beds. The purpose of using an electric tiller is to create loose soil for planting as well as weeding and aerating soil and stirring organic matter into soil such as compost.
