In agriculture, a plowshare or ploughshare (UK; / ˈ p l aʊ ʃ ɛər /) is a component of a plow (or plough). It is the cutting or leading edge of a moldboard which closely follows the coulter (one or more ground-breaking spikes) when plowing.
Wooden plows were carefully constructed of individually fitted boards and painted frequently to maintain a smooth surface. Steel plows can be sprayed with water in sub-freezing temperatures to form a smooth layer of ice on the plow surface. [2] The plow has a horizontal wedge to lift snow above the level of snow accumulation beside the track.
A reconstruction of a wooden mould-board plough. To grow crops regularly in less-fertile areas, it was once believed that the soil must be turned to bring nutrients to the surface. A major advance for this type of farming was the turn plough, also known as the mould-board plough (UK), moldboard plow (U.S.), or frame-plough. [21]

Ransome Victory Plough (American spelling "plow") is a type of single-share mouldboard plough commonly used throughout Southern Africa. Introduced into much of Southern Africa in the mid-1920s via European farmers and missionaries, it was quickly adopted over earlier, heavier models that required multiple spans (teams) of oxen.

A long-pole body ard with a knee-like brace is still found in some parts of China. In some parts of Europe with moist soils, the body ard's path was cleared by a ristle, a coulter-like implement used to reach greater depth. In Spain and Portugal this remains a separate tool, but elsewhere it was the precursor to the coulter.
