In addition, the successful design and technical characteristics allow the MTZ 1221 to be used equally effectively in various works in industry, utilities, construction and forestry. A distinctive feature that ensures such widespread use of the tractor is the combination of high power with both drive axles and fairly compact dimensions of the tractor.

The presence of a high agrotechnical clearance of 465 mm and traction parameters belonging to the second class allow the Belarus 1221 to additionally perform full care of tall agricultural crops. Taking into account the great demand for a multifunctional tractor, the MTZ company is currently assembling and producing five modifications of this agricultural machine with different operational and technical characteristics.

The differences between them are related to the parameters of the power unit used in the design, or more precisely, the degree of its compliance with certain environmental indicators. Increasing the environmental options for manufacturing the modification increases its export attractiveness. The modification MTZ 1221 Tropic (tropical version) also stands out for its unique design.

The use of tractors in ordinary agricultural life is far from uncommon. Self-propelled vehicles at different travel speeds can really help in carrying out heavy work in fields, cities, large areas, when towing transportation, etc.

Special equipment is designed for various types of rural work ; it requires preliminary care like any vehicle, as well as proper storage, care, and operation.

It is very important that at the beginning of work, if you are a beginner, you clarify all possible and important questions. It is necessary to clarify what kind of oil needs to be poured into the on-board “MTZ 1221” so that its operation is long and safe. This information is always contained in the technical documentation from the manufacturer.

An excellent choice would be M8DM, corresponding to GOST 8581-78, or M-10DM. High-quality analogues will also work.

Description and scope of application

The tractor of the MTZ 1221 model range is used to perform various types of rural and household work , ranging from the fact that it can be used to prepare the soil for sowing, ending with harvesting and transportation operations. The MTZ-82 tractor can be used for the same purposes.

Most often, this unit can be seen in forestry and public utilities among ordinary workers, or in larger industrial areas and construction sites. Special equipment is fully adapted for difficult working conditions under different temperature and climate conditions.

It works in areas where the soil may be loose, liquid or otherwise sinking , and the soil itself may have a bearing capacity (within not very large soil suctions, so that the equipment does not sink to the bottom).

Use of tractor in agriculture

There is an additional wide range of accessories and assemblies on the market. If necessary, you can purchase traction and coupling means, since sometimes it needs to be used with a combination of second-class vehicles.

That is, you may find all its functionality useful, and if necessary, combine it with a tractor from the third category, which has the same mechanism coupling elements, such as front and rear linkages.

The functionality is very common , although the design of the special equipment “MTZ 1221”, the photo of which only confirms this, is traditional, simple, and reliable. Regarding performance:

is very important for such tractors , since this is where all the work begins . Since it is equipped with a turbocharger, it can achieve high power levels during operation. The environmental side of its use meets the European level, so you can work on it from refueling to refueling.

All systems of special equipment are fully synchronized, so you can operate this machine safely.

European tractor models differ from Russian ones primarily in their higher price. The Bobcat tractor is no exception.

At the same time, they are characterized by increased reliability during operation. Read about one of these New Holland tractors.

Another example of European technology, which is written about on our website, is the Tatra-t815 dump truck.

What performance characteristics are affected by changes in tire pressure?

MTZ wheel pressure directly affects the performance characteristics of Belarus. Why is this question relevant for every tractor driver, since you can find out the optimal pressure readings in the operating manual and always set them? The fact is that MTZ tractors are universal. This means that the machines are suitable for a wide range of jobs depending on the attachments installed.

Tractors are equipped with attachments for plowing, sowing, harvesting and applying manure, digging, and snow removal. For popular models, you can find on sale more than 100 different attachment options. And that means it is simply impossible to answer unequivocally what pressure should be in the tires of the front and rear wheels of MTZ. For each task, taking into account the season and installed equipment, you will have to select your own pressure.

The pressure in the wheels of the MTZ tractor affects:

• Fuel consumption.

If the pressure in the tires of the Belorus tractor decreases, the contact area with the ground increases. And this, in turn, leads to an increase in fuel consumption: more power is spent on overcoming the increased friction force at the point of contact.

Of course, the difference in fuel consumption when operating a tractor with inflated and deflated tires will not be colossal. But it is still worth striving to reduce operating costs.

• Tire wear.

The pressure in the front and rear wheels of MTZ directly affects the wear rate of tires. In general, tractor tires are consumables: Belshina and Voltair, which are not the most reliable, have to be changed almost every year. But even on reliable Kama, incorrectly set pressure will not have the best effect.

In the case of low pressure, the contact area of ​​the wheels with the road surface increases, resulting in increased friction and internal stress of the tire frame. Over time, this will lead to cracks and blowouts, as well as increased wear on the edge of the tread.

In the case of high pressure in the wheels, the frame is under tension all the time, and the risk of cord rupture is high. Due to a decrease in the contact area, the load on the tread increases, and its pattern wears out faster. Also, tractor tires can be punctured if they are overinflated, which is especially important for tractors working on virgin soil.

• Wear of chassis elements.

By selecting the correct pressure of the MTZ wheels, you can extend the life of the chassis, which is the weak point of any tractor. The higher the wheel pressure, the worse they dampen vibrations and vibrations when driving over uneven surfaces. This means that the entire load goes directly to the chassis and suspension.

When the tires are overinflated, the tractor begins to “bounce” like a ball. This operating mode is dangerous for Belarusians; in this case, the tire pressure must be reduced. Lower pressure allows tires to better dampen vibrations. In this regard, when working in very difficult conditions, some tractor drivers reduce the pressure. But it is not recommended to operate the tractor in this mode for a long time.

Advantages and disadvantages

The Belarusian tractor MTZ-1221, the technical characteristics, description and some features of which are discussed above, has a number of objective advantages and certain disadvantages. The advantages of the unit include the following:

• Easy to operate, maintain and repair.
• Unpretentiousness and reliability.
• A cold start is provided, allowing you to start the engine in the cold.
• Availability of spare parts.
• Acceptable price.

Among the disadvantages is the possibility of engine overheating. When working in the heat at maximum power, it may simply boil. In addition, with economical fuel consumption, the tank reserve does not last long.

Conclusion For its technical data, Belarus has an affordable price.

At the same time, the unit is universal, can be used in various industrial and economic sectors, and is adapted to be equipped with various types of trailed and mounted devices.

Among domestic models, the vehicle is among the leaders in its class and can compete on equal terms with many foreign analogues.

How to choose the right radius of the front wheels for the MTZ-82

It must be said that the radius of the R20 front wheels installed on this model of the Belarusian tractor is optimal under standard operating mode.

However, the machine can also be used in winter, in conditions of high snow cover, as well as when working in quarries, swamps and other more difficult conditions.

That is why the manufacturer allows drivers to intervene independently and select wheels with other recommended parameters.

• If the equipment makes long journeys along asphalt roads, then the driver can install 7...8 - 18 wheels on it, which will reduce the tread height and the tractor will become more stable on hard surfaces.
• On the contrary, when it comes to using equipment in winter, which requires higher ground clearance, it is permissible to install wheels in dimensions 9...11.5 - 22...24, and the tractor will rise slightly above the ground, and soft mud grips will begin to more confidently pave the way in deep snow.
• When using equipment in the most extreme conditions, when driving through peat bogs or other unsteady surfaces, you will need to create a large torque not only on the rear, but also on the front wheels, which will require the installation of tires 12...14 - 25...26.

Important!

When installing wheels of an off-design radius, the driver should be prepared for more frequent routine maintenance to repair the suspension, bearings in the hub, change the oil and other procedures, since an off-design load on all systems provokes rapid wear of all parts.

Cabin

The driver's workplace is safe. The frame of the cabin itself is made of rigid, curved shaped profiles into which tinted spherical glass is inserted. In the roof of the cabin there is an emergency hatch and a ventilation and heating system, as well as a control system for some electrical alarm and lighting devices. The use of special sound-absorbing mastics and upholstery ensures the required level of sound insulation and moisture insulation.

In conclusion, I would like to note that the Belarus-1221 tractor, the price of which can range from 5-6 to 20-25 thousand US dollars, according to its owners, fully justifies the money invested in its purchase and is capable of trouble-free service for many years, reducing thereby, to some extent, the cost of agricultural products grown. In addition, the engine of this tractor operates in the least forced mode, which, of course, significantly contributes to an increase in service life. This point is noted by many owners of this car. The most wear-out component in a tractor is the gearbox bearings. This drawback also did not go unnoticed.

Advantages

Each special technique has its pros and cons. Naturally, it is important for every client who purchases such a unit to hear more about the advantages of this model. One of the main factors is that the tractor is very reliable and is absolutely suitable for any type of repair work in case of breakdowns. There will be no problems with servicing the Terrion tractor.

If we compare it with the MTZ 1221 2 model, it is just as innovative and has a well-equipped assembly.

Each customer will most likely compare the model with foreign competitors (for example, the Challenger tractor). It is believed that high-quality equipment can only be made in Europe. But the Minsk Plant proved the opposite, as it released a new MTZ 1221 onto the market, the price of which is more affordable, and the equipment is the same.

The tractor has already presented itself as one of the best and has not only a good diesel engine (as well as the T-70s), but also low maintenance, good power in order to perform and not fail when performing heavy work tasks.

In addition, the convenience is that you can fill it with foreign-made lubricating oils. This will not affect the operation of the vehicle in any way. A significant advantage is the interior, which is made for the convenience of drivers.

In addition to the modern style interior design, it has a comfortable seating and shaped carpets, panels and upholstery that are very easy to get used to.

The most important point is safety, so the cabin is made completely and the frame is of high rigidity, it ensures integrity from the tractor tipping over. The upper part of the body is made with a folding hatch so that the driver, if necessary, can urgently leave the cabin in the event of an accident.

Dimensions

Unlike pressure, MTZ tire sizes vary less. It is recommended to use the tire sizes specified in the owner's manual. But the manual contains several dimensions (for different conditions) that are suitable for a particular tractor. For each size, it is necessary to select a rim or disk so that the tractor can fully move and perform its functions. For example, for tires on MTZ-82 with a standard size of 15.5R38, a rim of size DW-14L38 is suitable, and for the front (8.3-20) - W7-20.

Attention: for each model in Belarus, there are factory recommendations for the selection of tires. You can find the data in the vehicle operating brochure.

Successful technical characteristics and economic indicators for the MTZ 1221 tractor make it a multifunctional, reliable assistant for performing work throughout the year; a detailed operating manual will allow you to immediately use the tractor with the greatest efficiency.

Positive qualities of the machine

The following advantages of the tractor deserve special attention:

• Simplicity of design.
• Excellent performance.
• High reliability.
• Unification of parts.
• Low cost of spare parts.
• Economical fuel and lubricant consumption.
• The ability to quickly diagnose a breakdown and short time to fix it.
• Safe use in the ambient temperature range from -40 to +40 degrees Celsius.

Maintenance

As everyone knows, special equipment can also break down. The main thing is that you carry out clutch repairs and steering repairs on time. The fact is that when one specific part breaks, it can “pull” the breakdown of another.

So, if there is play in the steering wheel, it is necessary to inspect and replace worn parts, and then adjust all mechanisms. As for the clutch, the signal to replace it is a decrease in power and noticeable “slippage” .

Maintenance repair of the MTZ-1221 clutch is necessary first of all. Without it, you will not be able to use the vehicle. Carry out diagnostics systematically in order to detect in advance a problem that is gradually developing.

In principle, such security measures are provided for by inspection coupons, so you just need to not violate the law and pass it when you should. Timely maintenance allows you to limit yourself to lubrication and replacement of worn parts, without rush jobs.

Maintenance of the steering control of the MTZ 1221 tractor is also very important . The life and health of the driver directly depends on it. If this system malfunctions, you can be very seriously injured when carrying out agricultural or other work.

Periodic inspection of the system is required for the presence of play, jamming and jerking when operating the tractor. Often a simple adjustment is all it takes to avoid major costs.

There are several specific thresholds that must be adhered to when servicing special equipment:

It is best to replace all the parts with new ones , but if you don’t have that kind of money, buy used ones. Of course, no one will provide you with any warranty periods for them, and you need to be prepared for this. You can also do tuning of the MTZ 1221 tractor yourself out of necessity or personal desire.

You can install wide wheels and boost the engine, giving it more power. It is enough to visit thematic forums to get a lot of ideas.

Device

The MTZ-1221 tractor is a large-sized 4-wheeled motor vehicle, which is equipped with 2 wheels measuring 14.9R24 and 2 wheels measuring 18.4R38. Overall dimensions of the vehicle: width – 2250 mm, length – 4950 mm, height – 2850 mm. At the same time, the wheelbase is 2760 mm.

The carrying capacity of the vehicle is no more than 4500 kgf, which is an order of magnitude greater than that of the MTZ-50 tractor. The device allows work to be carried out on all types of soil, including weak-bearing ones. The track on the front wheels is 1545-2265 mm, and on the rear wheels 1500-1900 mm.

There are 2 types of brakes: main and parking.

They are designed in a dry, mechanical disc design, but can be converted to an oil-bath design upon request.

Cabin and controls

The main tractor controls are located to the right of the tractor driver. They are levers: control of hydraulics of the linkage and attachments, manual supply of diesel fuel, activation of the PTO, control of the FDA, etc....

Since the MTZ-1221 can operate in reverse mode, the levers and switches are placed so that their use is convenient in both modes. The steering is fully hydraulic.

An additional advantage of this tractor model is a completely modern interior, designed for comfortable work. A well-designed, modern interior with upholstery made of high-quality fabrics and plastic panels is pleasing to the eye.

They also didn’t forget about the driver’s safety; a reliable metal frame will protect the driver when the tractor rolls over, and seat belts will keep them inside the cabin. There is a hatch in the roof, it serves as additional ventilation and as an emergency exit in an emergency.

The interior is equipped with heating and forced ventilation, which allows you to operate the car at any time of the year, but there is a serious lack of air conditioning in the basic configuration.

The large glass area provides a good overview. The rear window opens for additional ventilation. The noise insulation is pleasing, which is reflected in the use of high-quality soundproofing materials in the upholstery and special mastic for the cabin body.

Advantages and disadvantages

In addition to the already noted main advantage of the Belarus 1221, the combination of compactness and power, as well as high-quality technical characteristics, in their reviews, owners and machine operators note the following advantages of the MTZ 1221 tractor:

But also, based on the available reviews, we can conclude that there are certain shortcomings that are present in the MTZ 1221 tractor. Among them are:

• the need for frequent adjustment of the clutch, which is accompanied by labor-intensive work to remove the clutch housing and then install the clutch;
• difficulties starting the engine in winter;
• lack of a filter in the hydraulic system for cleaning and cooling hydraulic oil;
• inconvenient location of the differential lock adjustment switch.

Features of use

It is necessary to pay attention to the fluid in the radiator when the air temperature drops to +5 °C and below, as it freezes and makes it difficult to start the engine. /p>

The manufacturer recommends using antifreeze instead of water, which is more resistant to low temperatures.

You can fill the engine crankcase with M-8DM GOST 8581-78 motor oil, and TAD-17 and GOST 23652-79 transmission oils into the power transmission housing.

Run-in

The need for running-in is difficult to underestimate, because it is during this process that not only the running-in of all components and mechanisms is carried out, but also the following malfunctions are identified:

There are three types of running-in:

The car should be pre-prepared for running in:

The Belarus MTZ-1221 tractor idles for approximately 20 minutes. After this, the load increases.

The engine is listened to for the presence of extraneous noise. If leaks are detected, measures must be taken to eliminate them.

After some time, the speed is added and the load increases.

It is necessary to attach attachments up to 200 kg to the tractor, and slowly raise and lower the attachment.

Do not break in off-road or in areas with deep snow.

At the final stage of running-in, a control examination of the tractor and its mechanisms is carried out:

The entire break-in period will take about 30 hours, but you will be sure that the tractor is working correctly.

The manufacturer does not recommend using excessive loads on the machine during the first month.

If the running-in was carried out incorrectly or the period was shortened, then the operational life of the mechanisms and components, which begin to fail more quickly, is thereby reduced.
