Dongfeng mini tractor

Numerous diplomas and awards that the Dong Feng technique are winning once again prove its quality. The lineup is represented by machines with 3 and 4 cylinder engines, which are characterized by power and thrust. The company's specialists are constantly working on the modernization of equipment, therefore, they have achieved significant results in reducing the level of noise and vibration.

Advantages and disadvantages of the DongFeng model 244 mini tractor

A short list of benefits includes:

• four-wheel drive chassis;
• combination of excellent traction and coupling performance and low specific ground pressure;
• economical consumption of fuels and lubricants;
• two functional clutch mechanism;
• the presence of a two-speed power take-off and power steering;
• modern design of the driver's workplace.

Judging by the reviews of the owners, the structural and operational shortcomings of this model are typical for the entire range of small cars made in China.

First of all, this is a moderate build quality, the lack of complete information on how to eliminate failures and malfunctions on your own. In some lots, cheap, short-lived bearings are installed. Leaves much to be desired in the quality of rubber gland seals.

Features of the device

The Dong Feng 244 minitractor has all-wheel drive and a locking differential, which, together with an adjustable track, provides excellent maneuverability, cross-country ability and ease of control of the machine.

The model has a fairly high performance compared to analogues and at the same time has a relatively low cost. According to the latter indicator, this model is much cheaper than cars of Korean and Japanese production, although in terms of reliability and power it is in no way inferior to them. Currently, the production of a mini-tractor is fully automated, which excludes product defects.

Reliability

The high reliability of the mini tractor is due to the fact that the manufacturer uses only its own developments and parts. Moreover, the entire production process of equipment is accompanied by strict control and a variety of modern technologies, therefore, each machine produced has full serviceability, since defects are immediately recognized at the assembly stage.

Repair features

The equipment is quite easy to maintain and does not require large material investments. First, this is due to the extended service intervals. Secondly, each element of the tractor is characterized by increased durability and quality. And thirdly, all key mechanisms, components and assemblies are located in the most accessible place. It should be noted that the cost of consumables and spare parts is currently very acceptable.

Appointment

The DongFeng DF 244 mini tractor can really be called an ideal option for performing farming tasks. It can help you plow, fertilize, mow, remove snow, transport heavy loads, pump water and even dig a trench when you install the right attachments. In terms of versatility, the technique may well compete with heavier special vehicles, however, unlike them, this model exerts much less soil pressure, thereby not causing significant damage to the fertile soil layer. This is due to the relatively small mass.Also, the machine can boast of its maneuverability, which makes it possible to use it in a limited working space.

Transmission

The mechanical power train includes a gear transmission. 8 forward and 2 reverse speeds provide a choice of speed modes in the range from 1.12 to 25 km / h.

The undercarriage is made according to the 4x4 all-wheel drive scheme with the possibility of locking the closed two-satellite differential. The cross-country ability of the tractor is additionally ensured by high road clearance, chevron lugs of wide-profile tire tires.

To control the attachments, an on-board hydraulic system with a gear pump and a valve-spool hydraulic switch for operating modes is used. The universal suspension allows the machine to be aggregated with attachments of domestic and foreign production.

Price and offers

The average cost of a new mini-station wagon DF-224 is 140-150 thousand hryvnia (5100 - 5500 $). Modifications with power steering, safety arches and ballast weights are more expensive. A model with a cabin will cost 180,000 - 200,000 UAH (6600 - 7500 $).

On the market for used tractor equipment, there are offers, the cost of which is determined by the remaining resource, availability of standard equipment and appearance. You can buy a used DF model 224 in working order for 50-60 thousand (1800 - 2200 $).

The cost of cars with relatively low mileage is at the level of 100-120 thousand hryvnia ($ 3700 - $ 4400). A bonus attachment to such a purchase can be a plow, cultivator or other attachments of the middle price range.
