Disc Plow Introduction

A tillage machine that uses a concave disc to turn over soil. When a disc plow is pulled forward by a tractor, the disc rotates around its central axis, cutting through the soil around its perimeter. The tilled clods rise along the concave surface of the rotating disc and flip over to the side and rear, leaving furrows after tilling. Its tilling effect is the same as that of a moldboard plow, but the tilling quality is not as good. When tilling green manure fields, grassy areas, stony areas, and wet clay soils, it has a stronger cutting ability, better soil penetration, easier soil removal, and is less prone to clogging than a moldboard plow. The disc plow was invented around the end of the 19th century and subsequently saw significant development. By 1962, the world's disc plow production accounted for 10-16% of the total number of plows. It is widely used in the southern United States and central Oceania. China began using disc plows in the late 1950s, and began producing suspended, towed, and small disc plows for use with walking tractors in the mid-1960s.
