disk tiller

A disk tiller, also known as a disk harrow, is an agricultural implement used to prepare soil for planting. It works by pulverizing the soil, breaking up crop residues, uprooting weeds, and covering seeds.1

Disk tillers feature concave disks that rotate through the soil. Different configurations exist, such as the single-action two gang, which has two groups of disks that throw soil in opposite directions, and the tandem harrow, which uses two to four gangs in succession. Offset disk harrows are also used, particularly around low-hanging fruit trees.1

Disk plows, a type of primary tillage equipment, use round, concave disks to reduce friction by rolling rather than sliding. They are effective in sticky soils, fields with plow sole, dry ground, and peat soils, and are also used for deep plowing. Disk tillers are essential tools in the broader practice of tillage, which involves manipulating soil to create optimal conditions for crop growth.23
