Rollers are a secondary tillage tool used for flattening land or breaking up large clumps of soil, especially after ploughing or disc harrowing. Rollers are typically pulled by tractors today. Before mechanised agriculture, a team of working animals such as horses or oxen provided the power.
Small tilling equipment, used in small gardens such as household gardens and small commercial gardens, can provide both primary and secondary tillage.

Primary heavy duty disc harrows of 265 to 1,000 pounds (120 to 454 kg) per disc are mainly used to break up virgin land, to chop material/residue, and to incorporate it into the top soil.
