The tractor model MTZ-82 can be called the real pride of the post-Soviet industry. Their release was begun in the USSR, when in 1974 the first model left the assembly line.

It successfully continues today at the Minsk Tractor Plant, producing MTZ-82. So any domestic company can purchase proven equipment over the years, but manufactured in accordance with modern quality standards under the brand Belarus-82.

MTZ-82 is a deeply modernized MTZ-52, which was one of the most popular in the Soviet Union. MTZ-82 today does not lose its popularity in the CIS due to reliability, power and relatively compact size.

It should be remembered that the MTZ-82 design includes up to 70% of unified parts that can be used on other tractors, including the MTZ-50 and MTZ-52 models. All models MTZ -.

The MTZ-80/82 family of tractors was developed in the 70s of the last century, when the need arose to create universal special equipment competitive with foreign counterparts. This was the MTZ-82 model with an engine of up to 80 hp, which could be used to solve a whole range of tasks, from transporting felled trees in public utilities to cities to efficient plowing of fields. MTZ-82 belongs to the 1.4 class.
  Belarusian 82 It is important to understand that constructively even modern Belarus-82 tractors represent deeply modernized MTZ-52  and they are distinguished mainly by modern exterior cladding, a functional and safe cabin, the equipment of a modern high power engine. Of course, we must not forget about the huge number of minor design changes that increase the overall strength and reliability of the structure.

Characteristics of the MTZ tractor to look at the video.

Today, the MTZ-82 tractor of various years of production can be used almost everywhere, they easily tolerate both northern frosts and the difficult road access of rural roads, driving through mud during snowmelt.

Most models have increased engine speed and good speed, so it can be used to transport heavily loaded trailers over long distances (compare with). On the Internet there is confirming this video.

Fuel consumption

For each model, be it a modern Belarus-82 tractor or the Soviet MTZ-82, or, the accompanying documentation indicates the rate of fuel consumption on the basis of which it can be assumed real consumption, often slightly different from the standard.

It must be remembered that the actual fuel consumption depends largely on the following aspects:

• Climatic conditions.
• Season.
• Wear design.
• The quality of fuel and lubricants.
• Weight attachments.
• The complexity of the work performed.

Therefore, it is always necessary to apply a correction factor to the linear norms, which increases the base parameter.

The easiest way to measure fuel consumption is to fill the unit with a full tank and drive 100 kilometers on a tractor with a uniform load. Then you can determine exactly how much fuel was used  both at the whole distance, and per kilometer, liters per hour.

Calculation formula for MTZ-82

  Determination of fuel consumption To determine the exact amount of fuel consumption, you can use a formula that has been successfully tested by time and is actively used for MTZ-82 tractors.

The formula includes the following basic parameters:

• Fuel consumption kg / hour, denoted as "P".
• The power of the tractor is a standard value of 0.7, the result of transferring the power of the MTZ-82 motor from kW to horsepower.
• Specific fuel consumption, denoted beech "R". For the model MTZ-82 is equal to 230 kW per hour.
• Engine power in horsepower is denoted as “N”. In the basic configuration MTZ-82 is usually equipped with an engine with a power of 75 horsepower, but today there are often options with motors with a capacity of 80 horsepower.

To accurately calculate the fuel consumption, it is necessary to calculate by the following formula: P = 0.7 * R * N.

The fuel consumption for the tractor in the basic configuration will be 12 kg per hour. Given that a liter of diesel fuel weighs about 840-875 grams, the flow rate is quite large.

However, during the survey, some tractor owners identified real fuel consumption from 7 to 10 liters per hour. Perhaps this is due to the fact that the engines in modern models (for example) are more economical.

Specifications

The MTZ-82 tractor was originally produced in several modifications, and to this day the units used in the CIS countries can differ greatly from each other, primarily in the method of starting the engine, appearance, attachments and type of transmission, which often gear ratios differ.


  Attachments MTZ 82 MTZ-82 can be equipped with different attachment points, have a different agrotechnical prospectus, have or not have a system for working on sharp slopes and a hydraulic control system. Often used a variety of rubber, selected for climatic conditions.

But the semi-frame construction of various modifications of the MTZ-82 always has unified elements, such as:

• Front wheel guides.
• Rear wheels of large diameter.
• 75-80 hp diesel engine, located in front of the hull.

Dimensions and weight

MTZ-82 differs in relatively small dimensions., and has the following dimensions:

The standard agroscall for this model is 46.5 centimeters, for modifications with a wheel reduction gear, it is 65, for the MTZ-82N version, the ground clearance is 40 centimeters. The mass of the unit is 3,600 kilograms. It can be used everywhere, including for public services in cities, it should not harm the road surface, as well as.

  MTZ hydraulic system According to standard MTZ-82 is completed with mechanical transmission  with power steering and nine-speed gearbox with two ranges, equipped with a reduction gear.

Initially, the model did not assume the presence of a hydraulically controlled gearbox, but on modern tractors it is often installed with the ability to switch under load. The hydraulic system allows you not to turn off the clutch when shifting gears within the four speed ranges.

The separate-modular hydraulic system includes a gear pump, a hydraulic distributor and a hydraulic cylinder, with the help of which the attachments are controlled.

On the old tractors, most of which were produced in the USSR, the locking is controlled mechanically, with a pressure pedal located on the floor. Modern modifications are equipped with a hydraulic system - you can switch the mode using the switch located under the dashboard.

Engine

On the tractor MTZ-82 installed four-cylinder engine D-240 or D-243. This four-stroke unit produced at the Minsk Motor Plant  and has a liquid cooled sub-split combustion chamber. The camera is located in the piston.

On some tractors, you can also find a preheater, which allows you to quickly and efficiently prepare the engine for operation in the winter. The heater ПЖБ-200Б is installed only if the ambient temperature during tractor operation is below 0 ° С, as soon as it reaches a value of 5 ° С in spring, the heater must be removed, dried and set aside until autumn.

The MTZ-82 engine has an average working volume of 5.75 liters. and power of 80 hp in modern models and 75 hp in earlier versions. The unit can be equipped with an electric starter or a 10 horsepower starting motor and a start blocking function in case the gear is already engaged.

Transmission

MTZ-82 is equipped with a modern transmission and has a stiff suspension of the rear wheels and a semi-rigid front, has a balance bridge. To secure the rear wheels, the terminal connections on the axles are used, thanks to which the tractor operator can smoothly change the track width, varying it from 140 to 210 cm. The track can be varied for the front wheels, but only in steps, each step is 10 cm.

Attachment Equipment

The MTZ-82 tractor can be equipped with the following attachments:

• Loader.
• Front loader.
• Blade.
• Snow dump
• Road brush.
• Ladle.
• Plow.

Thanks to the unified work elements on the MTZ-82, you can install a wide range of modern attachments for municipal and construction equipment.

It is important to remember that maintenance of MTZ-82 should be carried out systematically. The priority can be called maintenance in the spring and autumn, as well as preparing the equipment for work in particularly difficult conditions, for example, in desert areas, mountains, tundra.

It is advisable to adhere to the following scheduled maintenance schedule:

• Superficial - every 60 hours.
• Standard - every 240 hours.
• In-depth - every 960 hours.

It is important not only to perform basic operations, but also   timely repair any damage found  and prevent malfunctions.

Operating Instructions - Guide to Action

In order for the tractor to serve the owner as long as possible, and his work was uninterrupted, the following requirements must be observed when operating the unit:

• After the end of the shift, check for leaks of oil, fuel, and water.
• Add fuel regularly to the starting engine.
• Check the oil level only 20 minutes after the engine is running.
• Regularly check the water level in the radiator and drain the condensate from the pneumatic system.

When operating in difficult weather conditions - necessarily inspect the tractor according to individual requirements.

For example, clean the radiator net when working in a desert area.
