Over more than 40 years of operation, the MTZ 82(80) tractor has proven its ability to be used in a wide range of jobs. The layout of the transmission and hydraulic attachment system makes it possible to combine the tractor with various special mounted machines, which has become proof of the versatility of application in various sectors of economic activity. The presence of an arsenal of mounted machines allows you to quickly re-equip a tractor to perform one or another technological operation, which has a positive effect on the level of machine loading and optimization of production costs. This article describes the classification and types of attachments for the Belarus tractor, and also contains a short list of the main models of devices used.
MTZ 82
Classification of mounted machines
By mounted we mean equipment installed on the tractor chassis by connecting it to its rear or front hydraulic linkage, as well as using additional brackets in the structure installed on the MTZ frame.
Based on their purpose, mounted machines are divided into groups:
- agricultural
- construction and utilities
- forest
- general purpose
Based on bringing the equipment into working condition, they are divided into non-drive ones and those requiring power take-off from the PTO or tractor hydraulic system to ensure operation of the active components of the mounted machine.
Tractor bucket design
The most common way to divide buckets for MTZ tractors is by working volume, but it is far from the only one. Tractor hitches can also differ in their design, which makes them more suitable for performing certain, highly specialized tasks.
The tractor bucket can be:
- Communal.
Such attachments usually have a working volume of up to 0.8 m3 and are designed to perform a wide range of municipal and agricultural tasks. They are used for collecting garbage and clearing sites, pouring grain, fertilizers, feed, building materials, removing manure, feeding livestock, etc.
Typically, the design of the utility bucket for the MTZ tractor is lightweight, because the hitch is operated in relatively favorable conditions. To increase productivity, such buckets are often equipped with stiffeners. To successfully grip sticky masses, forks or knives can be installed on the edge.
- Bulldozer.
The bulldozer bucket for the MTZ tractor has a small volume and a reinforced design, since it is intended for leveling work, clearing sites, and removing construction waste. It is possible to lift loads using a bulldozer bucket with a tractor, but this is not its main purpose - usually special equipment removes debris and moves bulk materials, moving the mass in front of it. That's why they are called bulldozers. To improve the quality of work, they are often equipped with knives along the edge of the bucket.
- Snow removal.
The bucket for the MTZ tractor for snow removal is a shovel. Actually, this is the popular name for snow removal tractor buckets. The design feature, as in the previous case, is a small bend and a structure reinforced with stiffening ribs. Like a bulldozer, the snow removal bucket on the MTZ tractor pushes the mass (not necessarily snow, it can be dirt, lumpy debris, tree branches and windbreaks) in front of itself, practically without lifting it. The main difference from bulldozer-type tractor attachments is that the edge of the shovel is equipped with a rubber band to prevent damage to the road surface.
Specialized buckets for MTZ tractors
Depending on the need to perform certain work, you can select the following tractor buckets and shovels:
- Loading.
By installing a loading bucket on a Belarus tractor, you can turn it into a front loader. Such canopies have a lightweight design. Their main purpose is to perform loading and unloading operations.
- Lattice.
A mesh or lattice bucket on a tractor allows you to simultaneously perform two operations: reloading bulk materials and sifting them. Similar structures are also used when digging up root crops, so that the crop can be immediately separated from the earth clods.
- Trench.
The trench bucket for the MTZ tractor has a reinforced design: it must have reinforced sidewalls and stiffeners. This attachment simultaneously cuts out a portion of the soil and lifts it. To facilitate work on heavy soils, the edge of the trench tractor knife is equipped with pointed teeth, which can be welded or removable.
- Grab.
The clamshell or jaw bucket for the MTZ tractor is a structure of two parts - jaws. Usually the lower jaw is fixed, and the upper jaw can rise and fall, “biting off” a portion of hay, compost, and bulk materials. Such attachments work well with viscous substrates that would stick to conventional equipment in a lump.
- Reinforced.
The reinforced bucket is installed on Belarusians of the middle and heavy classes. The attachments are designed for the development of hard, rocky, frozen soils. Usually these are not the most capacious tractor buckets, but they have a design that is maximally reinforced with stiffening ribs and may also have a serrated edge or removable knives.
- Silos.
Belarus tractors operating at agricultural enterprises are mounted with silage attachments. They are a classic lifting bucket, with forks lowered on top of it in the manner of a grab. This design of the hitch ensures reliable capture of hay, silage, compost, feed and other heterogeneous masses and prevents them from flying out while the tractor is moving.
- With side unloading.
This bucket for the MTZ tractor has a small bending radius and looks more like an elongated container, one of the sides of which does not have a wall. The possibility of side unloading is convenient if you need to quickly reload fine-grained bulk materials into containers or the body of a truck.
Agricultural mounted machines
The popular use of MTZ in the agricultural sector as part of mounted and trailed units is due to the classification of the tractor as a universal row-crop machine. A wide range of agricultural equipment mounted on the tractor allows the MTZ 80 to be actively used in technological processes of crop and livestock production.
According to their intended purpose, agricultural attachments are divided into the following subgroups:
- for continuous and inter-row tillage
- for sowing and planting crops,
- applying mineral fertilizers and treating crops with chemicals.
- for mowing green masses
- harvesting forage and vegetable crops
- for livestock maintenance
- for preparing feed in livestock farming
Devices for continuous and inter-row tillage
The traditional arable attachment for the Belarus tractor is the three-body ploughshare plow PLN 3-35. In parallel with the development of cultivation technologies and the improvement of plowing machines, innovative developments have appeared that, under certain conditions, make it possible to increase the speed and quality of plowing. A significant increase in productivity is provided by plows with body rotation, machines with a wide working grip of bodies and increased processing speed.

The fundamental factor when choosing a cultivator is the design, shape and principle of operation of the working bodies in accordance with the characteristics of the physical composition of the cultivated soils and cultivation technology. In terms of the main working parts, cultivators can be equipped with pointed shares, spring chisel-shaped rippers, and flat-cutting shares. Additionally, the cultivator includes leveling rollers or tine harrows.

Row-crop cultivators for inter-row cultivation of KRN and USMK crops are equipped with a number of working parts. The nature of the equipment of the cultivator sections depends on the row spacing, the cultivated crop and its growing season, as well as on the weediness and physical condition of the soil. Additionally, in their design, cultivators can be equipped with fertilizer sowing devices for simultaneously fertilizing crops with mineral fertilizers. The above interrow machines have a number of improved modifications and imported analogues.

Grass cutting devices
Mounted mowers differ in their design by the segment or disk principle of operation of the cutting element. The drive is carried out from the rear PTO of the tractor; the unit is transferred from the transport position to the working position by a hydraulic cylinder as part of the mounted machine. There are many modernized versions of these mowers on the market. Due to their high maneuverability, mounted mowing units are used in mowing fields, small irregularly shaped areas, gardens, as well as in public utilities when mowing roadsides, park areas and lawns.

Vegetable harvesting machines
In the arsenal of mounted vegetable harvesting machines for the Belarus tractor, there are several versions of potato diggers and digging devices for harvesting carrots, onions and garlic. The vegetable digger consists of a digging plowshare organ, adjustable in stroke depth, and two conveyors driven from the PTO. The cut soil along with the tubers enters the main conveyor, where the soil spills through the rods of the device. Then the tubers without soil are fed onto a cascade conveyor and thrown out over the treated area.

Active use of mounted machines with MTZ 80 is associated with work on small farms. For work in large enterprises, the arsenal of cx. Belarus tractor machines are complemented by a fleet of trailed equipment with higher productivity and power utilization.
In addition to the active use of tractors with trailed and semi-trailer special machines that have separate chassis, in the agricultural sector the power of MTZ is used to drive stationary devices. This group may include: portable conveyors, grain sorting stations, threshers and crushers, feed grinding plants.
What volume of bucket is needed for different types of work?
Figuring out what volume a bucket is needed for a MTZ tractor is not so easy. It is clear that the capacity and productivity of the hitch largely depends on its design (we will consider this parameter later) and the type of material with which you have to work.
Here is the approximate amount of materials and products (in tons) that will fit into the bucket of a MTZ tractor. For convenience, the data is presented in the table.
| Volume, m3) | 0,3 | 0,4 | 0,6 | 0,8 | 1 | 1,2 | 1,5 | 1,8 |
| The ground is dry | 0,48 | 0,64 | 0,96 | 1,28 | 1,6 | 1,92 | 2,4 | 2,88 |
| The ground is wet | 0,6 | 0,8 | 1,2 | 1,6 | 2 | 2,4 | 3 | 3,6 |
| Gravel | 0,54 | 0,72 | 1,08 | 1,44 | 1,8 | 2,16 | 2,7 | 3,24 |
| Dry coarse sand | 0,48 | 0,64 | 0,96 | 1,28 | 1,6 | 1,92 | 2,4 | 2,88 |
| Wet sand | 0,66 | 0,88 | 1,32 | 1,76 | 2,2 | 2,64 | 3,3 | 3,96 |
| Newly fallen dry snow | 0,05 | 0,07 | 0,1 | 0,14 | 0,18 | 0,22 | 0,27 | 0,33 |
| Snow is wet | 0,24 | 0,32 | 0,48 | 0,64 | 0,8 | 0,96 | 1,2 | 1,44 |
| Beets/carrots/potatoes | 0,19 | 0,26 | 0,39 | 0,52 | 0,65 | 0,78 | 0,98 | 1,18 |
| Corn | 0,22 | 0,3 | 0,45 | 0,6 | 0,75 | 0,9 | 1,13 | 1,36 |
| Sawdust | 0,07 | 0,09 | 0,14 | 0,19 | 0,23 | 0,28 | 0,35 | 0,42 |
How to choose the volume depending on the type of work performed? General recommendations for working with buckets of different capacities and designs are given in the table.
| Types of jobs | Basic, m3 | Reinforced, m3 | Maxillary, m3 | ||
| 0,4 | 0,6/0,8/1,0 | 1,2/1,5/1,8 | 0,6/0,8/1,0 | 0,6/0,8 | |
| For light work (grain, wood chips, hay, feed and fertilizer, dry snow) | + | + | + | + | + |
| For medium work (dry sand, dry soil, hay, root crops) | + | + | + | + | |
| For heavy work (gravel, wet soil, wet sand) | + | + | + | + | |
| For leveling work (soil removal, ice removal, frozen soil, large stones) | + | + | + | + | |
But the main criterion when choosing a bucket is compliance with the Belarusian class. Large and reinforced attachments will not help in the work if they are installed on a low-power tractor.
