DT–20 is a Soviettractor with rubber wheels. It had 6kN pulling force. 248 400 pieces were produced from 1958 to 1969 in Kharkiv. Its main aim was the usage in the gardening and in orchards.
The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a socialist state in Eurasia that existed from 30 December 1922 to 26 December 1991. Nominally a union of multiple national Soviet republics, its government and economy were highly centralized. The country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic. Other major urban centres were Leningrad, Kiev, Minsk, Alma-Ata, and Novosibirsk. It spanned over 10,000 kilometres east to west across 11 time zones, and over 7,200 kilometres north to south. It had five climate zones: tundra, taiga, steppes, desert and mountains.
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery used in agriculture or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, but nowadays a great variety of tasks. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
Kharkiv, also known as Kharkov, is the second-largest city in Ukraine. In the northeast of the country, it is the largest city of the Slobozhanshchyna historical region. Kharkiv is the administrative centre of Kharkiv Oblast and of the surrounding Kharkiv Raion, though administratively it is incorporated as a city of oblast significance and does not belong to the raion. Population: 1,439,036 (2017 est.)
Plans of DT-20 were based on the DT-14B’s structure, but it had better power. It can handle trucked and mounted devices as well. It had five variants, each with a dedicated purpose, with variant gages and with little modifications.
It is a 1500 tractor with an angular suspension. It has no hydraulic system. There is built to the system a D-20 diesel engine which has a 13.2 kW power. Its transmission has six onwards and five backwards scales. Its maximum speed varied between 5 and 17.6 km/h high speed.
The Diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel, which is injected into the combustion chamber, is caused by the elevated temperature of the air in the cylinder due to the mechanical compression. Diesel engines work by compressing only the air. This increases the air temperature inside the cylinder to such a high degree that atomised Diesel fuel injected into the combustion chamber ignites spontaneously. With the fuel being injected into the air just before combustion, the dispersion of the fuel is uneven; this is called a heterogenous air-fuel mixture. The process of mixing air and fuel happens almost entirely during combustion, the oxygen diffuses into the flame, which means that the Diesel engine operates with a diffusion flame. The torque a Diesel engine produces is controlled by manipulating the air ratio; this means, that instead of throttling the intake air, the Diesel engine relies on altering the amount of fuel that is injected, and the air ratio is usually high.

A dual-clutch transmission (DCT) is an automated automotive transmission, closely related to a manual transmission. It uses two separate clutches for odd and even gear sets. It can fundamentally be described as two separate manual transmissions with their respective clutches contained within one housing, and working as one unit. Although usually operated in a fully automatic mode, many also have the ability to allow the driver to manually shift gears in semi-automatic mode, albeit still using the transmission's electrohydraulics.
