Tractor mts 1221 its modifications. Design features of the machine. Device, technical specifications

  "Belarus" was created specifically to perform a wide range of agricultural work and is able to satisfy all the needs of the farmer in hard work. The tractor's tractor class is 2.0, which allows it to be used both for preparing the soil in the pre-sowing company and for carrying out transport and utility works. The versatility of the MTZ-1221 is in the classic layout for this class of tractors. It is possible to use the tractor when processing various types of soils in the most severe climatic conditions.

Thanks to a wide range of additional equipment, devices and traction coupling devices, MTZ-1221 can be aggregated with modern equipment and agricultural machinery. The tractor inherited from its predecessors the traditional simplicity of design, high performance and reliability.

Engine mTZ tractor-1221

As a power unit, the tractor uses a diesel engine D-260.2S with a power of 130 hp. (96 kW) equipped with a turbocharger. The modern inline six-cylinder engine meets all the requirements for safety and environmental friendliness, and also differs in very modest oil and diesel fuel consumption. The MTZ-1221 engine can use both imported and domestic fuels and lubricants and may well make up foreign analogues of this class.

Cabin

The modern comfortable cabin is installed on the MTZ-1221 tractor. Cab frame are bent shaped profiles to ensure the safety of the driver. To protect against direct sunlight during operation, tinted spherical glasses are used. Inside the cab are the main controls of the tractor. The interior of the cab of an agricultural tractor is distinguished by a simple taste with the use of carpets and upholstery. In the roof of the cabin MTZ-1221 is an emergency hatch and ventilation system. For greater comfort, the cabin has sound insulation with sound absorbing upholstery and mastic. Outside the cab mounted rearview mirrors, sun visor and light signaling devices. The cab complies with ROPS and OESD safety standards. Electric windshield wipers are provided on the front and rear windows.

Hydraulic system MTZ-1221

In order for the tractor to be able to control various trailed and attachments, it has a hydraulic system that controls the trailed, mounted and semi-mounted agricultural equipment. It is possible to install two types of a separate-modular hydraulic system on a tractor:

- with two vertical hydraulic cylinders built into the hydraulic lift;
  - with a horizontally autonomous hydraulic cylinder.

The tractor's hydraulic system is simple and easy to maintain. The oil tank has a sufficiently large capacity to work with hydroficated equipment, requiring a large amount of oil to drive the working bodies. In the hydraulics of MTZ-1221 can be poured both domestic and imported oil.

Technical characteristics of MTZ-1221

Without this technology can not do! Construction, utilities, forestry - everywhere there is a job tractors.

Pull the "car" out of the mud - and then a tractor will come in handy! Let's take a look at one of them and focus on a second-class tractor, model 1221.

MTZ 1221 whose technical characteristics, we will consider later - this is the 2.0 class of special equipment. Purpose:

1. Perform all sorts of tasks in agriculture.
2. Preparation of the sowing company.
3. Work related to harvesting.

In addition, MTZ 1221 is used in the public sector, the construction industry, industry. Used for work in the forest industry.

MTZ 1221 photo equipment that you see, works in different climatic zones and on different soils. Including serves the soil with low bearing capacity.

Due to the possibility of using a wide sector of attachments and additional equipment, it aggregates a class 2 with a large number of special equipment. It can work with some machines a class 3.

The MTZ 1221 video tractor, the work presented in the article, gives an idea of ​​its capabilities and potential. The simplicity of the design, the reliability of components and mechanisms in combination with high performance make it a reliable and indispensable assistant in many areas of the economy.

  In addition, the MTZ 1221 tractor consumes the minimum amount of fuel. There are no problems with its repair. Minor malfunctions can be carried out in the field, without resorting to the constant movement of equipment in stationary workshops.

Reliability and continuous operation of the tractor is possible with proper maintenance. For these purposes, a special set of measures has been developed, which includes:

1. Daily activities. Maintenance MTZ 1221 is carried out every 10 hours of its work.
2. Then the complex TO perform after 125 working hours. The next 250 and 500 hours.

On MTZ 1221 reviews are positive. In operation, the technique is experiencing maximum loads. In connection with the constant power impact on the mechanisms, the role of maintenance increases. To learn about adjustment of MTZ 1221 valves and in general about maintenance   tractor MTZ 1221, we recommend that you familiarize yourself with the video.

We remind you that subsequent repair and preventive measures must be performed after 1000 and 2000 hours of work. All detailed information is described in

  General technical indicators

Please note that these are general technical indicators of the MTZ 1221, the characteristics of the state of the components and assemblies will be given below.

After consideration of the common for tractor MTZ 1221 technical characteristics, let's get acquainted with the power unit installed on it, find out the state of the brake system. Go through the installed gearbox and electrical equipment. Video MTZ 1221 in the field, its potential, see the beginning of the article.

Device of the MTZ 1221 tractor

Let us consider in more detail the power unit, gearbox and electrical equipment of the MTZ 1221 tractor.

Power unit

The tractor is fitted with a turbocharged diesel power unit. Location inline. The number of cylinders is six. The motor is characterized by low consumption of oil and diesel. Diesel meets all necessary requirements for exhaust emissions into the atmosphere. The unit is omnivorous and can run on domestic and imported fuels.

Transmission

At MTZ 1221 transmission 16/8. Step option, with gears of constant gearing. Switching takes place using synchronizers. Closed clutch. The type is permanent. Dual-disc friction principle of operation.

Electrical equipment

Figure 2 - Assembly units of equipment, electrical circuit MTZ 1221.

The working scheme of MTZ 1221 includes:

• generator with a rated power of 12 kW;
• on-board network for consumers of electric energy at 12 V;
• brake system.

MTZ 1221 devices, which we are considering, are equipped with disc service brakes. Principle of action: load on the rear part with the subsequent transfer of effort through the FDA drive to the front wheels.

The parking brake is synchronized with the service brakes. The system is considered reliable and balanced in size and weight of equipment, designed for additional loads of trailing devices.

Trouble-shooting

Table 3 shows the classic malfunctions of MTZ 1221.

The MTZ 1221 tractor the price for new and second-hand equipment

A complete set with full and additional attached equipment will cost the potential buyer 2 155 000 r. MTZ 1221 price with a hydraulic decelerator is more expensive.

Conclusion

Without exaggeration, we can say that the technique is reliable. MTZ 1221 in work, see the video material. The versatility, the ability to use additional equipment and various configuration options make MTZ 1221 in demand in many areas of the economy.
