The three-point hitch ( British English : three-point linkage ) is a widely used type of hitch for attaching ploughs and other implements to an agricultural or industrial tractor . The three points resemble either a triangle, or the letter A. In engineering terms, three-point attachment is the simplest and the only statically determinate way of rigidly joining two bodies.
52-500: The JCB Fastrac is a high-speed agricultural tractor series manufactured by JCB Landpower, part of the JCB group. Production began in 1991, with continual development to the present day. Generally the maximum speed of most models is 65 km/h (40 mph), but slower (40 km/h) and faster (80 km/h) versions are produced. All models have six-cylinder diesel engines. Initially supplied by Perkins Engines then Cummins ,

The hydraulically operated and controlled three-point hitch used the draft of the mounted tool to moderate the depth of the tool and therefore the load on the tractor (automatic depth control or draft control). In addition,

780-467: Is often present in modern three-point hitch systems. The draft of the implement, the amount of force it is taking to pull the implement, is sensed on the top link and the hydraulic system automatically raises the arms slightly when the draft increases and lowers the arms when the draft decreases. There are five different hitch sizes, called categories. The higher category hitches have sturdier lift arms and larger connector pins. There are also variants to

On 22 August 2006 the Dieselmax, driven by Andy Green , broke the diesel engine land speed record, attaining a speed of 328.767 mph (529.099 km/h). The following day, the record was again broken, this time with

The particular geometry of the linkage that attached the plough to the tractor enabled forces generated by the plough to be applied to the rear wheels of the tractor. This redirected the plough's resistance into downward force on the drive wheels, which enabled Ferguson's tractor to be much lighter and more manoeuvrable than earlier models of farm tractor with equivalent tractive force and traction .

1196-442: The 1950s and 1960s, farmers often would have to purchase the same brand implements as their tractor to be able to hook up the implement correctly or to best effect. If a farmer needed to use a different brand of implement, an adaptation kit—which were typically clumsy, ill-fitting, or unsafe—was sometimes needed. The pressure toward vendor lock-in was a two-edged blade for the salespeople. It was an advantage in cases where it encouraged

Hydropneumatic suspension is used on the rear of all models and on the front of the 4000 and 7000 series Fastrac. This is similar to that used on some Citroën cars. These Fastrac machines have hydrostatic steering similar to most agricultural tractors with only

The hitch's utility and simplicity have since made it an industry standard. The three-point hitch is made up of several components working together. These include the tractor's hydraulic system, attaching points,

The N variations are common in "quick hitches" and allow larger tractors to easily hook onto smaller utility implements.

The implement is secured by placing a pin on the ends of the posts. The hitch lifting arms are powered by the tractor's own hydraulic system. The hydraulic system is controlled by the operator, and usually a variety of settings are available. A draft control mechanism

Towing with a drawbar is a good, practical system for many purposes, and it has continued to be used even up to today, but the three-point hitch outperforms it in several ways (described below). Harry Ferguson patented the three-point linkage for agricultural tractors in Britain in 1926. He had long been a champion of the importance of rigid attachment of

With the advent of nonproprietary status,

The two lower arms—the hitch lifting arms—are controlled by the hydraulic system, and provide lifting, lowering, and even tilting to the arms.

Some of these systems, with one-point or two-point hitching, were not well suited to lifting heavy implements. They also presented the problem of incompatibility between brands of tractors and implements, applying pressure toward vendor lock-in that many farmers resented. During

During the decade of 1916 to 1926 he developed his ideas through various iterations, duplex and triplex, mechanical and hydraulic, to arrive at the patented form. During the next decade, he continued explaining and selling his hitches and implements and even produced his own model of tractor in cooperation with David Brown Ltd. via

Ferguson often faced

At one time he made vehicles in Eckersley's coal yard in Uttoxeter. The first trailer and the welding set have been preserved. In 1948, six people were working for the company, and it made the first hydraulic tipping trailer in Europe. In 1950, it moved to an old cheese factory in Rocester , still employing six. A year later, Bamford began painting his products yellow. In 1953, he developed JCB's first backhoe loader, and
2444-616: The three-point hitch system is to transfer the weight and resistance of an implement to the drive wheels of the tractor . This gives the tractor more usable traction than it would otherwise have, given the same power , weight , and fuel consumption. For example, when the Ford 9N introduced Harry Ferguson 's three-point hitch design to American production-model tractors in 1939, it was a light and affordable tractor competing principally with row-crop tractors such as Farmalls that did not yet have three-point hitches. At 2,500 pounds (1.1 t),
2496-538: The three-point hitch would prevent the tractor from flipping backwards on the drive wheels if the implement being dragged were to hit a rock or other immovable obstruction. Ferguson and his colleagues developed several innovations to this device (e.g., the hydraulic lift and depth control) which made the system workable, effective, and desirable. In 1938, after almost two decades of trying to sell Henry Ford on using Ferguson's system on tractors mass-produced by Ford, Ferguson finally convinced Ford. The American mass-market debut
2548-534: Was a flat bar with holes in it, and the implements were trailers, with tongues that attached to the drawbar with a pin through a hole. The main reason why this was the default hitching idea is that it was the natural follow-on from the days of horse-drawn implements, which were towed as trailers by the horse or team (and often had an operator's seat). In fact, for decades during the mechanisation of agriculture in Europe and North America, as tractors gradually replaced horses in increasing degrees, existing implements from
