Excavator YuMZ-6
The YuMZ-6 excavator is used when working in soil categories 1-4 and loading all kinds of materials.
The YuMZ-6 excavator is equipped with a blade and at the same time a backhoe bucket, which can also function as a straight shovel, which depends on the installation. The YuMZ-6 excavator has the ability to operate at temperatures from -40 to +40 °C. To operate an excavator in frozen soils or soils above category 4, preliminary loosening of the soil is necessary. With this machine design, it is possible to work with replaceable equipment.
Features of operation
This technique is easy and simple to operate. The spacious, bright and safe excavator cabin has excellent visibility.
Technical characteristics allow the YuMZ excavator to operate in any weather with air temperatures from -40ºС to +40ºС. The equipment is not afraid of increased levels of dust.
To prevent premature wear of the hydraulics and extend the service life of the machine, it is necessary to regularly clean the bottom of the oil tank, timely replace filters, oil and wipers, and check the tightness of all components in the engine.

Cost of ownership
The EO 2621 excavator, the price of which does not exceed one and a half million rubles (this is lower than that of Caterpillar), is available to most commercial and government enterprises involved in agriculture, construction, and maintenance of utility and energy systems.
On the secondary market, its average price is six hundred thousand rubles, and the amazing reliability of the excavator’s systems and mechanisms gives the owners of these used machines reason to believe that they own practically new equipment.
Consumables and spare parts for this tractor are quite cheap. In addition, he is unpretentious in terms of service. It can be repaired at any site equipped with electric hoists and a welding machine, which also reduces the cost of ownership.
Engine
The manufacturer installed a 4-stroke, 4-cylinder, water-cooled diesel engine without turbocharging on the wheeled YuMZ-6. The basic model of the tractor was equipped with two different models of power units: D-65 and D-242-71.

general information
YuMZ-6 is a representative of universal wheeled tractors for general purpose, part of the “Belarus” line, initially produced by the tractor plant in Minsk, but later developed at YuMZ. Types of work and operations permitted for the tractor:
- agricultural activities using semi-mounted, mounted devices, multifunctional trailers;
- Men at work;
- construction;
- forestry operations;
- other types of special work;
- drive functions for stationary and mobile units;
- transportation on trailers.
An individual line of mounted units has been created for the YuMZ-6, adding various functionality to the tractor necessary for certain jobs. The car can be transformed into:
- earth mover;
- loader;
- bulldozer;
- excavator, etc.
Thanks to its successful design and ease of maintenance, the tractor can be converted both at the factory and in a specialized workshop on site.

Modifications
During the period of time that the Southern Machine-Building Plant produced the YuMZ-6 tractor, various modifications created on the basis of the basic model were available to consumers.
There were four in total:
The power unit of models whose names included the letter “L” was started using a starting engine (if instead of the letter “L” the letter “M” appeared, this meant that the engine was started by an electric starter). The “K” in the model name indicated that the tractor was equipped with a cabin with increased dimensions.

Separately, I would like to highlight the YuMZ-6K model, which was originally planned to be used for industrial purposes. In this regard, the plant decided to abandon the agricultural attachments (located at the rear), installing instead mounts for a bulldozer blade and an excavator bucket. When the basic YuMZ-6 tractor was discontinued, this modification, however, took its place in agricultural use.
Attachments
It is difficult to select the most popular ones among the attachments. Due to the wide range of applications of YuMZ6, the number of attachments is quite large.
The most popular devices are:
- two- and three-furrow plows;
- hillers;
- snow shovels;
- trailers;
- trolleys;
- seeders;
- potato planters;
- root diggers;
- harrows;
- mowers;
- hay rollers;
- fertilizer spreaders.

Excavator-tractor YuMZ-6: technical characteristics
The YuMZ-6 tractor itself became a descendant of the famous MTZ-5 tractor from the same manufacturer. The car retained the continuity of its design and was in many ways similar to its predecessor. The agricultural universal row-crop tractor belongs to the 1.4 traction class and is distinguished by a classic semi-frame layout for machines of this purpose.
Engine and transmission
YuMZ-6 excavators were equipped with two types of four-stroke diesel engines without turbocharging:
- D-65 volume 4.94 l;
- D-242-71 with a volume of 4.75 liters.
The engine power of the YuMZ-6 excavator was determined by its model. The factory D-65 produced 60 hp, and the D-242-71 produced 62 hp. The D-65 power unit was supplemented with an electric starting engine. The nominal crankshaft speed was 1800 rpm.
The transmission system of the YuMZ-6 tractor-excavator consists of a five-speed gearbox with a two-flow dry clutch. The car reaches speeds of up to 24.5 km/h. The gearbox is equipped with double gears. Some tractor models were supplemented with a doubler gearbox. The specific fuel consumption of YuMZ-6 reaches 185 g/hp*h. The machine can climb slopes of up to 10 degrees.
Device
The ordinary YuMZ-6 tractor of draft class 1.4, the prototype of which is the MTZ tractor, became the basis for several modifications of YuMZ excavator-loading equipment. The traditional semi-frame base consists of a strapping frame and a bulldozer support frame. To operate the working equipment, a rotary column and a boom with a bucket are used. Drives of working equipment are hydraulic.
The basic design uses piston hydraulic cylinders. Both hydraulic drives are completely independent devices, the operation of which is ensured by one tank. The functioning of the boom and bucket in the YuMZ excavator is ensured by one of the hydraulic drives using a distributor and pumps. The second hydraulic drive ensures the operation of the bulldozer shovel, supports and turning mechanism.
The popularity of this equipment is explained by its versatility and the fact that most of the attachments are unified. Small dimensions make it possible to operate in urban environments, or in areas where access to large construction equipment is limited. The wheelbase ensures the excavator's mobility and good maneuverability.
Modifications
During the work on the YuMZ-6, the Yuzhny Machine-Building Plant produced not only more than 100 thousand vehicles, but also offered the consumer several special modifications:
- YuMZ-6L, externally reminiscent of the MTZ-50, was distinguished by a rounded radiator grille. The vehicle was equipped with a starting motor;
- YuMZ-6AL - a vehicle with a steering rack adjustable in height and angle, a modified instrument panel, a rectangular hood and structural modifications in the brake system;
- YuMZ-6KL is an industrial modification of the tractor, produced without a rear linkage system. Instead, the manufacturer installed standard mounts for bulldozer and excavator equipment. In essence, it is the YuMZ-6KL modification that can be considered an excavator. After the first model YuMZ-6A was discontinued, this version took the place of the base one. An agricultural machine was developed on its basis;
- YuMZ-6AK - was first released in 1978. The equipment cabin had better visibility, and the hydraulic system began to be equipped with power and position control.
Development and release
YuMZ tractors are universal wheeled vehicles that perform agricultural and transport work. The developer of the tractors was the Southern Machine-Building Plant, also known as the plant named after. L. I. Brezhnev. The company produced not only tractors.
The main object of production of the plant were rockets, rocket engines, as well as other high-tech products, the development and production of which was carried out by the efforts of designers, mechanics and engineers of the then Soviet state. Other names of YuMZ are “Yuzhmash”, “DAZ” (Dnepropetrovsk Automobile Plant).
According to the opinion that developed over the years of existence of tractors produced by YuMZ, these machines were considered the best in Ukraine and in neighboring countries. YuMZ tractors were supplied to the Baltic countries, Russia, Kazakhstan, Uzbekistan and Poland. Some of the equipment was even exported abroad, for example, to Cuba, China and Japan. Two years after the release of the first YuMZ 6, 100 thousand copies of this equipment were already produced.
The start of production began with the launch of the MTZ-5LS tractor production line in the early 60s of the last century. They were produced by the Minsk Tractor Plant together with Ukrainian engineers and mechanics. The markings of the equipment were preserved, and the tractors that came off the MTZ assembly line became known as “Belarus”.
Later, after the creation of its own tractor machine from Yuzhmash, the production and export of the already famous “Belarus” continued. At the end of the 70s, the YuMZ trademark finally appeared, cars with the sign of which can now be bought on the move and in good condition throughout the country.
Tractor machines from YuMZ were considered the best in those years and received about. Also, they have been repeatedly recognized as the best agricultural machine of the year. This equipment was distinguished by its high engine life, because the production base was a defense enterprise with the best specialists, materials and the latest technical developments.

Application
A modification of the YuMZ-6 tractor with excavator equipment has become widespread among domestic consumers. Despite the fact that the machines have been out of production for quite some time, the technician continues to work on farms of various types.
Initially, the YuMZ-6KL model with a 65-horsepower engine and excavator equipment was intended for use in construction and public utilities. Relatively small dimensions and high performance became the key to the machine’s success in Russia. In addition, the YuMZ-6 excavator has an undeniable advantage over its Western counterparts, and this advantage is its price.
A tractor based on the YuMZ-6KL adapted for agriculture has become suitable for row-crop work, harvesting, planning and preparing fields, sowing and transporting goods in conjunction with agricultural and industrial machines.

Design
The entire structure of the EO 2621 excavator is based on the YuMZ 6AK wheeled tractor . The semi-rotating hydraulic boom is mounted on a vertical column resting on the tractor rear suspension bracket.
Initially, the design of the YuMZ tractor was not designed for use as an excavator chassis. Therefore, at ChTZ, its frame was strengthened with additional strapping, and the fuel tank was moved forward, installed in front of the radiator grille. The rear support legs of the excavator hitch were not enough to provide a tight stop during work.
Therefore, a straight bulldozer blade, which has its own frame and hydraulic drive, also plays the role of additional support, as well as a counterweight when digging pits, trenches and loading operations. About
