A rototiller is a gardening tool used to prepare soil for planting. It features rotating blades or tines that dig into the ground, breaking up compacted soil and mixing in organic matter. This process improves soil aeration and drainage, making it easier for plants to grow. Rototillers come in various sizes, from small, handheld models to larger, tractor-mounted versions. They are commonly used in home gardens, farms, and landscaping projects. By using a rototiller, gardeners can save time and effort compared to manual tilling methods, such as using a shovel or hoe.
