tillers

Tillers are agricultural implements used to loosen and turn soil in preparation for planting. They range from manual hand tools to powered machines that employ rotating tines to break up compacted earth. The term commonly refers to rotary tillers (rototillers), which churn soil as they move. Tilling is a form of soil preparation; it is distinct from cultivation, which focuses on weed control and mixing soil around existing plants.

Manual tillers include hand-operated cultivators with prongs or blades driven by the user’s motion. Powered tillers are motorized and come in front-tine and rear-tine configurations, using gasoline, electric, or other power sources. Front-tine models are generally lighter, while rear-tine units deliver more digging power for tougher soils. Larger varieties include tractor-mounted tillers for fields.

Operation involves selecting an appropriate depth, guiding the machine across the soil, and maintaining steady movement to avoid gouges. Safety practices include clearing debris, keeping hands away from the tines, and turning off the engine before adjustments. After use, inspect and clean the tines and store the machine dry.

Environmental considerations include soil structure and erosion. Deep or frequent tillage can disrupt soil ecology; many modern practices emphasize reduced tillage or no-till methods to preserve residue and soil health.

Origin of the term: a tiller can refer to a person who tills land; to till means to cultivate soil.
