A rotavator, also known as a rotary tiller or rototiller, is a farm implement used for preparing soil for planting by breaking it up, mixing in amendments like fertilizers or compost, and creating a smooth, uniform seedbed. It typically consists of rotating blades or tines that churn and aerate the soil as the implement is pulled or driven across the field by a tractor or other power source. Rotavators are commonly used in agriculture and gardening to facilitate soil cultivation and seedbed preparation.
