Top-5 used tractors for the farmer| ||87
Ефективна діяльність фермерських господарств України зумовлює об’єктивну необхідність певний час використовувати бувші у використанні трактори зарубіжного виробництва, які мають достатній ресурс, і за умови помірного річного завантаження ще тривалий час забезпечать високу продуктивність, надійність та якість виконання робіт.
Let's try to characterize the Top-5 used tractors for farms, which are presented on the Ukrainian market.
John Deere
On the secondary market of Ukraine, one of the most popular areJohn Deere wheeled tractors 6D series. According to statistics, approximately 370,000 of these tractors work in the fields of the world. Ukrainian farmers prefer 6D series tractors due to a harmonious combination of high reliability, engine power, economy, maximum comfort and versatility.
6D series tractors exist in two models: 6115D with 118 hp engine power, and 6130D with 130 hp Both tractor models are equipped with upgraded 4-cylinder 4.5L PowerTech diesel engines with common rail fuel injection, variable geometry turbines, intercooling system and rated engine speed of 2100 rpm.|| |101

Електрогідравлічна трансмісія Power Reverser має 9 передач переднього та 9 заднього ходу. Якщо необхідно виконувати такі роботи, як скошування трав чи пресування соломи, то для таких операцій краще підходить трансмісія Top Shaft з синхронізованим верхнім валом, 9 передачами переднього та 3 передачами заднього ходу з «сухим» зчепленням. У будь-якому випадку, завдяки вдало підібраним оптимальним передаточним відношенням трансмісії, завжди можна вибрати рекомендовану швидкість.
The 6D Series tractors offer a choice of two drivetrains: Mechanical Front Drive (MFWD) for maximum tractive effort and power transfer, or Adjustable Single Drive (2WD) for more economy and it is used, as a rule, during the performance of light work (for example, transport).
The hydraulic system of the 6D series tractors is equipped with a constant flow hydraulic pump, which has a capacity of 67 l/min. and creates a pressure of 19.5 MPa at an engine speed of 2100 rpm. For precise operations with the use of a hydraulic motor, a hydraulic system configuration with three valves is provided.
To drive aggregated machines that have active working bodies, 6D series tractors are provided with an independent two-speed power take-off shaft (PTO), which has a frequency of 540 or 1000 rpm. When changing to a lower or higher gear, or even when the tractor stops, the GDP will always maintain the set frequency. The presence of such a GDP makes it possible to perform almost any work, including the use of tools that require high power in a wide range.
The 6D series tractors are equipped with a reliable three-point hitch system, the load capacity of which is 3150 kg.
Fendt
On the secondary market of low-power tractors, Ukrainian farmers quite often preferFendt tractors 200 Vario with engine power from 77 to 111 hp .with. Characteristic features of these tractors are high reliability and fuel economy. Tractors are produced in five modifications, the difference between which is mainly in power.

The tractors are equipped with 3 - cylinder engine AGCO Power with a working volume of 3.3 liters. The engines are equipped with an AGRex external exhaust gas recirculation system and a DOC diesel oxidation catalyst. The nominal frequency of the crankshaft of the engine is 2100 rpm, and at a frequency of 1750 rpm, the engines develop the maximum torque, which can be from 306 to 463 N*m. The torque reserve reaches 37%. The specific fuel consumption for Fendt 200 Vario tractors is 288 g/kW*h. The tractors have a fuel tank with a volume of 125 l.
Vario stepless gearbox guarantees comfort while driving and saves fuel. The forward movement of the tractor in the range of speeds from a minimum of 0.02 km/h to a maximum of 40 km/h takes place without shifting gears, which allows you to precisely adjust the speed. The speed range for reversing is from 0.02 km/h to 12.5 km/h. The transmission allows the machine to come to a complete stop even on steep slopes, lock it using the active stop control function, and then start smooth movement again.
The basis of the hydraulic equipment of Fendt 200 Vario tractors is a Load-Sensing pump with a capacity of up to 104 l/min and a pressure in the hydraulic system of 200 bar. Thanks to this, it is possible to intensively use the front loader at low engine speeds. The maximum load capacity of the rear linkage is 4204 kg, and the front one is 2540 kg.
For the aggregation of working machines with active working bodies, a rear PTO is provided, which has working modes 540, 540E and 1000. The front PTO 540 E reaches a frequency of 540 rpm even at low engine speeds, and thus reduces fuel consumption.
All the main functions of the Fendt 200 Vario tractor can be controlled with one hand. The Variostick joystick, which is conveniently located on the right console, provides control of the tractor in full compliance with the work being performed.

In conclusion
Despite the popularity of the new equipment, among small and medium-sized farmers of the leading European countries there is an increasing demand for used tractors. Agricultural producers in England, France, Germany, and the United States have three or four used tractors for one new tractor purchased. According to statistics, more than 50% of mechanized work is performed by farmers with tractors purchased on the secondary market.
In developed countries, the main sellers of used tractors are dealerships, which are able to carry out high-quality pre-sale preparation, ensure proper maintenance, and if necessary, and repairs.
In Ukrainethe secondary market of tractors for domestic farmers will develop under the conditions of creating a network of dealerships and service enterprises, workshops and purchase sites and restoration of used machines, components and aggregates, their sale, rental or leasing, maintenance and repair during warranty and post-warranty periods, provision of spare parts to farms.
