What is an implement to break up clods of earth?

An implement used to break up clods of earth is called a "cultivator." Cultivators are designed to loosen and aerate soil, making it easier to plant seeds and improve water penetration. They can come in various forms, including hand-held tools or larger, tractor-mounted equipment. Using a cultivator helps prepare the soil for gardening or farming by breaking apart compacted soil clumps.
