Engine mts 1221 specifications. Description and modification of the tractor

  (otherwise "Belarus") releases "MTZ-Holding". This is the second most popular model after the MTZ 80 series. The successful design, versatility allows this car to remain the leader in its class in the countries of the former USSR.

Description and modification of the tractor

The MTZ 1221 model is considered a versatile row crop tractor. 2nd grade. Due to the various options for execution and a variety of attachments and trailed equipment, the list of work performed is very wide.

  First of all, it is agricultural work, as well as construction, municipal work, forestry, transportation of goods. Available in such   modifications:

• MTZ-1221L - option for the forest industry. Can perform specific work - planting trees, collecting whips, etc.

• MTZ-1221V.2 - a later modification, the difference is the reversible control post with the ability to rotate the operator’s seat and twin pedals. This is an advantage when working with rear-mounted units.

• MTZ-1221T.2 - with an awning-frame type cabin.

Other modifications, characterized by higher power.

Did you know?The first model MTZ 1221 was released in 1979.

Device and main nodes

Consider a little more detail the main components and the device MTZ 1221.

  This model is a wheeled front-wheel tractor. That is, planetary gears are mounted on the front axle.

  Front wheel drive - small radius, rear - large. It is possible to install twin rear wheels. This reduces the pressure on the ground, increases the maneuverability and maneuverability of the machine. On the model 1221 is installed diesel engine D 260.2 130 l. with. This six-cylinder engine with in-line placement of cylinders has a volume of 7.12 liters, unpretentious to fuel and lubricants.

  Such an engine is distinguished by operational reliability and ease of maintenance. Spare parts and components for the engine are not a deficiency, and it is easy to find them.

Important! The engine fully complies with the latest international environmental and safety standards.

Fuel consumption MTZ 1221 - 166 g / hp at one o'clock.   Later modifications are completed with engines D-260.2S and D-260.2S2.

The difference between them and the main model is in increased power of 132 and 136 hp. respectively, against 130 hp at the base model.

• Transmission

  MTZ 1221 gearbox for 24 driving modes (16 forward and 8 reverse). The rear axle is equipped with planetary gearboxes and a differential (with three modes "on", "off", "automatic").

  The power take-off shaft is installed in a two-speed version, with a synchronous or independent drive.

Forward speed   - from 3 to 34 km / h, back - from 4 to 16 km / h

The hydraulic system of the described model serves to control the work with the trailed and mounted units.

  Exists two options   hydraulic systems:

1. With two vertical hydraulic cylinders.
2. With an autonomous horizontal hydraulic cylinder.

  In any variant of the hydraulic system, it is possible to adjust the force and position of the equipment.

• Cabin and management

The workplace is made of reinforced metal profile. Comfortable work provide sunscreen and noise insulation. Control is carried out from the post to the right of the operator and an additional post in the top dashboard of the cabin.

  From the post adjustment of fuel supply, control of electrical equipment.

Use of MTZ-1221 in agriculture

The versatility of the tractor allows it to be used for various jobs. But the main consumers were and remain farmers.

The machine shows itself well in all types of field work - plowing, sowing, irrigation. The dimensions of the MTZ 1221 and a small turning radius make it possible to process small and complex portions of the fields.

Did you know?With this tractor, almost all mounted and trailed equipment (seeders, mowers, diskators, etc.) produced in the CIS countries is aggregated.

When installing additional electrical equipment and a compressor, the 1221 series successfully works with the equipment of world manufacturers.

Advantages and disadvantages

The main advantages include:

• price   - costs much lower than the majority of world models of tractors. Only Chinese manufacturers can compete with it;
• reliability and simplicityin service. Repairs can be carried out by a single mechanic in the field;
• availability of spare parts.

  Among the shortcomings should be noted:

• small tank capacity;
• frequent overheating of the engine, especially when working in hot climates.
• incomplete compatibility with equipment of European and American manufacturers.

  Today, the described tractor is the most massive and popular tractor in its category. Reliable, powerful, unpretentious machine created by our experts for our fields.

Considering the high cost of imported equipment, an insufficient number of spare parts and high-quality service, and a lack of high-class machine operators and mechanics, MTZ 1221 will be found in agricultural enterprises of our country for quite a long time.

Cost and purchase of MTZ 1221 tractor

A tractor Belarus 1221 can be bought both from authorized dealers and in the market of used vehicles.
  It is better to purchase a new tractor from an authorized dealer, where it is possible to select a modification in accordance with the stated requirements, as well as to receive subsequent warranty and post-warranty service. The cost of the initial configuration ranges from 2 million 200 thousand rubles and above. In addition, it is also possible to purchase various attachments for the production of MTZ, as well as other agricultural equipment needed in the economy. Another advantage of purchasing an MTZ 1221 tractor from a dealer is the ability to retrofit an agricultural machine purchased. Among the possible additional equipment can be identified: air conditioning, creeper, additional ballasts, front PTO.
  But if there are restrictions on financial assets, you can pick up ads for the sale of used MTZ 1221, which in 2006-2008 will cost about 1 million 300 thousand rubles.

The high-quality technical characteristics, high economic indicators, and the successful construction of the MTZ 1221 tractor make it a highly efficient and reliable helper for a variety of agricultural work throughout the year.
