In this publication it is a question of the first sample of domestic tractors of a TYa Yarilo series of production of JSC Ukragrokom. On a tractor the Oyep12 AO firm engine in capacity of 180-260 h.p. It is established meets both to requirements of the European EUKO-2 standard, and requirements of resource-saving technologies. Maintaining agricultural production.
Specific fuel consumption of 208 and 200 g/kW x hour that allows to spend about 17 l/hectares of a plowed land.

Among domestic tractors it is necessary to pay attention to the first samples of a TYa Yarilo series of production of JSC Ukragrokom, a traction class 3-4 with engine capacity of 180-260 h.p. which is executed at higher technological level in comparison with other domestic tractors. On it establish engines of DeutzAG firm of a model range of Vr6m1013 E (180 h.p.), VR6M1013 to EU
(215 h.p.), VR6M1013 ESR (260 h.p.) that meets as requirements of the European standard
EVRO-2, and requirements of resource-saving technologies of maintaining agricultural production. On engines the three-stage system of purification of fuel – the SEPAR filter + is established
two filters of thin cleaning and advanced coupling of coupling of LUK firm.
As a result of tests of the Yarilo TYa-200 tractor it is established that the stock of a torque of engines, makes 37,42 and 47 %. Specific fuel consumption of 208 and 200 g/kW · hour,
That allows to spend about 17 l/hectares of a plowed land.
Structurally the tractor has a continuous bearing frame and forward rotary wheels. At the expense of design features rational distribution of its weight respectively on a forward axis and a back axis – 62 and 38 % is reached that at an agregatirovaniye with agricultural cars provides the maximum coupling of wheels with the soil and increase in traction effort.
The torque stock in 37-42 % allows to overcome short-term overloads, thus engine turns within 1400-1700 rpm provide constant pressure in a gear shifting box and by that increase its reliability and durability.
The hydraulic system on a tractor is divided into hydrosystem of a steering and hydrohinged system that doesn’t allow mixing of oils of these two systems and thus increases durability, reliability of work of hydrosystems of a tractor.
Also bandage system of a binding of hydrodistributors and hydropumps that provides convenience and ease at performance of repair work is applied. In hydrosystem of hook-on cars of a tractor highly reliable explosive couplings are used, and also gate-type couplings which at pressure drop in hydrosystem on 10-20 units (i.e. at a rupture of a hose of a high pressure or other breakages), block supply of oils from the pump are developed and pump over it back in a hydrotank.
On a tractor the ergonomic cabin with the central arrangement of a post of management that allows to work with the different hook-on and hinged equipment is established, including to use a tractor on processing of row-spacings and harvesting. In a cabin the adjustable seat on the pneumoshock-absorber that creates comfortable conditions for the machine operator in operating time is established, reduces his fatigue. Comfort is provided by tinted glasses of a cabin and doors. In the middle the cabin is covered with shumopogloshchayushchy materials that considerably reduces level of a stream of sound pressure which gets into a cabin. The cabin is equipped with central air and heating.
In wheel reducers of the forward leading bridge firm cuffs are used
Sim-Rit that excludes an effluence of oil and increases motor potential of a tractor as a whole.
