A tiller is a gardening tool used to prepare soil for planting. It breaks up and aerates the ground, making it easier for seeds to grow. Tillers can be manual, requiring physical effort, or powered by engines, which makes the task quicker and less labor-intensive. In agriculture, tillers are essential for maintaining healthy soil structure. They help mix organic matter into the soil, improving its fertility. Additionally, tillers can control weeds and pests, contributing to better crop yields. Many farmers and gardeners rely on tillers to enhance their planting processes and ensure successful harvests.
