Disc plough have three or more individually mounted concave discs that are inclined backward to achieve maximum depth.
They are particularly adapted for use in hard, dry soils, shrubby or bushy land, or on rocky land.
It reduces friction by making a rolling bottom in place of a sliding one.
Its draft is about the same as that of the moldboard plow.
The disc plough works to advantage in situations where the moldboard(MB) will not, as in sticky nonscouring soils; in fields with a plow sole; in dry, hard ground; in peat soils; and for deep ploughing.
The disc-plough bottom is usually equipped with a scraper that aids in pulverizing the furrow slice.
Disc plough are either trailed or mounted integrally on a tractor.
