disk harrow

Modern disc harrows are tractor-driven and are raised hydraulically.

It is a largely outdated piece of farm equipment, having been replaced by more modern disc harrows and deeper, stiff-toothed rippers.

Some highly skilled farmers, particularly in dry areas, prefer disc harrows to the plough, believing that it is never wise to invert the topsoil.

Disc harrows consisting of gangs of concave steel discs are dragged at an angle to the line of draught.

The chief implements made by the Stoddard Manufacturing Company were mowers, hay rakes, press drills, and disc harrows.

Before the invention of the modern tractor, disc harrows typically consisted of two sections and which were horse-drawn and had no hydraulic functionality.

Disc harrows are primarily used to chop up soil that has been recently plowed to eliminate clumps and loosen the soil if it has been packed.

Throughout World War II H.V. McKay Massey Harris exported over 20,000 Sunshine drills, disc harrows and binders to England to facilitate the increase in food production.

Chain harrows are often used for lighter work such as levelling the tilth or covering seed, while disc harrows are typically used for heavy work, such as following ploughing to break up the sod.

Brinly-Hardy designs, manufactures and sells lawn care products including aerators, carts, lawn vac systems, dethatchers, sweepers, broadcast spreaders, sprayers, and rollers; gardening equipment such as plows, disc harrows, and cultivators and landscaping products such as rear blades and box scrapers.

In the southern hemisphere the so-called 'giant discs' are a specialised kind of disc harrows that can stand in for a plough in very rough country where a mouldboard plough will not handle the tree-stumps and rocks, and a disc-plough is too slow (because of its limited number of discs).

But later, as a young reporter in rural Orange County, N.Y., my beat was an endless parade of the dead: farmers mangled by disc harrows, highway victims smeared over the blacktop, suicides with heads turned inside out by shotguns, picnicking families electrocuted by lightning, drowned children, bludgeoned husbands and wives, ad nauseam.
