disc harrow
Noun: A disc harrow is a type of agricultural implement used for soil cultivation. It consists of a series of concave metal discs (or disks) mounted on a common axle, set at an angle to the direction of travel. Its primary function is to cut into, break up, and smooth out the soil, often after initial plowing, to prepare a seedbed or to incorporate crop residue.
The term "disc harrow" is used to refer to the specific farm implement. It is a compound noun where "disc" (or "disk") describes the shape of the cutting components, and "harrow" indicates its function as a soil-pulverizing tool. * The farmer attached the disc harrow to the tractor to break up the clods of earth. * Using a disc harrow helps to level the field and control weeds before planting.
