te20 hydraulic pump free sample

Many thanks for the T20 Hydraulics Video – Very well put together. I bought it because my T20 hydraulics are under-performing. I wonder if you might be able to give me a bit of advice?

It was restored and rebuilt by the students at Bicton Agricultural College as part of their engineering course. It is pretty much in excellent condition, but the links will not lift anything much above the weight of a man (not my cutter bar mover for example), and even then only if the engine is at full revs. As soon as the revs drop or the engine is switched off, the links start to fall. I have had a good look through, pulled the pump out and most things seem to be in good nick. No movement on the bushes etc. The one thing that I did notice is that, although the pump has an oscillator fork, there is no oscillator drive strip…. I think it is otherwise an old style pump – it has the old style combined relief valve and does not have spaces for o rings on the valve chambers suggesting it is the gasket type. Would the lack of an oscillator drive strip cause any real problems apart from making it more likely that the control valve will stick? The relief valve looks like it is in good shape, and so I am not sure that is the cause of the links dropping…. The only thing I can see that might be causing it is the fact that they didn’t put any gaskets between the valve chambers and the body of the pump. As it doesn’t have o rings (or space for them) either, would this be enough to let the linkage drop?

The Ferguson TE20 is an agricultural tractor designed by Harry Ferguson. By far his most successful design, it was manufactured from 1946 until 1956, and was commonly known as the Little Grey Fergie. It marked a major advance in tractor design, distinguished by lightweight, small size, manoeuvrability and versatility. The TE20 popularised Harry Ferguson"s invention of the hydraulic three-point hitch system around the world, and the system quickly became an international standard for tractors of all makes and sizes that has remained to this day. The tractor played a large part in introducing widespread mechanised agriculture. In many parts of the world the TE20 was the first tractor to be affordable to the average farmer and was small and light enough to replace the draft horse and manual labour. Many TE20s remain in regular use in farming and other work and the model is also a popular collector"s item for enthusiasts today.

By the early 1930s, the linkage design was finalised and is now adopted as international standard category I. Just one prototype Ferguson System tractor, known as the Ferguson Black, was built to further technical development and for demonstrating to potential manufacturers. During 1936, the first production Ferguson tractors were built in Huddersfield, Yorkshire, by the David Brown Company. That tractor, the Ferguson Model A, incorporated Harry Ferguson"s "suction side" hydraulic control system, the key to solving sensitive automatic control of three-point mounted implements, patented on 5 February 1936 (patent no 470069). The combination of Ferguson"s converging three-point hitch, patented on 3 July 1928 (patent no 320084) with his "suction side control" valve is the key to the success of all subsequent Ferguson and later Massey Ferguson "Ferguson System" tractors, the most important of which are the TE and TO 20 models. (It was the production of the Model A that led to the David Brown line of tractors in 1939).

During the war years, the Ferguson design team developed many improvements to both tractor and implements and started to make arrangements to manufacture in the United Kingdom. The agreement with Ford in 1938 was to include production at the Ford plant at Dagenham, Essex, but the UK Ford company would not do it.Standard Motor Company of Coventry to produce a Ferguson tractor incorporating all their latest improvements and to be known as the TE20. As well as allowing Ferguson to get his tractor into full production, the deal was of great benefit to Standard, because the tractor would be built in its huge "shadow factory" which had been an aero engine plant during World War II but was then standing empty. Standard developed a new wet-liner engine for the tractor, and for Standard"s road cars, such as the Vanguard.

Production started in the late summer of 1946, nearly a year before the last Ford Ferguson came off the line in Detroit in June 1947. The break with Ford left Harry Ferguson and his US company with implements to sell but no tractors. To make up the gap until the new Ferguson factory in Detroit started in October 1948, more than 25,000 Coventry-built TE20s were shipped to the US and Canada. The TO (Tractor Overseas) 20 was virtually the same as the TE20 with a Continental engine Z-126 fitted instead of the Standard engine.

At the time of its introduction the Ferguson three-point linkage was unique to the TE20, and to gain the full utility of the tractor the farmer also had to purchase specially-designed implements to work with the tractor. Ferguson initially designed and manufactured a range of implements for the TE20 in-house, but as the tractor"s popularity spread other manufacturers began designing their own machinery for the TE20 in agricultural, industrial, construction and horticultural applications. The idea that the three-point linkage made the tractor and its implement into a single mechanised unit was marketed as "The Ferguson System", presenting a wholly new and entirely mechanised form of agriculture. By 1950 there were over 60 official Ferguson implements for the TE20, many of which had not been seen in mechanised tractor-mounted form before. As well as basic implements such as ploughs, harrows and cultivators, the range included a number of trailers and loaders, seed drills, a side-mounted baler, a very rare "wraparound" combine harvester, a muck spreader, a sickle mower and a powered auger. With its power take-off, the tractor could also drive stand-alone equipment, such as pumps, milking machinery or circular saws, by belt or driveshaft.

Harry Ferguson merged his worldwide companies with Massey-Harris of Toronto in July 1953, three years before TE and TO20 production ended, hence the change of name on the serial plate to "Massey-Harris-Ferguson". The Ferguson 35 replaced the old line in the US in 1955 and the TE20 in the UK in 1956; production in the UK starting in September of that year following re-tooling of the factory. Harry Ferguson remained Chairman of Massey Harris Ferguson until 1957, when he left over an argument over the Ferguson TE60 or LTX project as it is known. He continued his hobby of motor racing and set up Harry Ferguson Research, which produced the P99 Race car, which won the Oulton Park Gold Cup in 1961 with Stirling Moss at the wheel.

517,651 TE20 tractors of all models were built at Banner Lane, Coventry. In mid-1953 Ferguson merged with Massey-Harris to become Massey-Harris-Ferguson. The new company continued both Massey Harris and Ferguson brands until December 1957, when it became Massey Ferguson. The new FE35 was introduced in October 1956 in grey and gold livery and became the red and grey MF35 at the Smithfield Show in December 1957.

A fleet of seven Ferguson TE-20s was used on the 1955–58 Commonwealth Trans-Antarctic Expedition which was led by Edmund Hillary. Four petrol-engined and three diesel models were used. Some were supplied as half-tracks, with steerable front skis, whilst others of the New Zealand team were fitted with an extra wheel on each side and full caterpillar tracks, developed by the expedition in the Antarctic. In both cases, the track kits were easily removable and in light conditions the tractors were used on standard wheels and tyres. A canvas cabin was added for windproofing. Other than this, the tractors were totally standard – two were even fitted with a standard farmyard hydraulic front-loader for loading and unloading supplies. Reports were made at regular intervals to the Ferguson company and these show the tractors to have been reliable and effective – being capable of climbing a 1-in-7 slope of "hard polished ice where a man cannot walk without crampons", as well as operating in conditions of −10 degrees Fahrenheit. Under Hillary these tractors were driven to the South Pole, becoming the first vehicles to be driven to the pole, and the first overland journey to the pole since Captain Scott. The tractors were left at the pole for the use of American researchers.

A TE20 is the star of a TV series for preschool children, The Little Grey Fergie, which premiered in the UK on 17 October 2013. The show is based on the Norwegian children"s story and TV series Den lille traktoren Gråtass.
