Model features

In order to convert the tractor into an excavator, a strapping frame was designed and attached to it, which is necessary to enhance the power. On this frame there is a rotary column with a rotation angle of 160º, operating from a two-cylinder hydraulic drive. The boom and bucket operate from the same drive. The excavator is equipped with various attachments.

Excavator equipment

The backhoe loader is equipped with;

several replaceable buckets;
grabs of various sizes;
loader.

This makes it a universal transport vehicle, which is also small in size and indispensable for carrying out work in places that are difficult to reach for other equipment.

Excavator Application

Using a grab, fertilizers, straw, bulk materials, and other cargo are loaded. Using a backhoe:

digging pits with a dump or removing the excavated soil;
digging trenches and holes.

All work can be carried out on various soils:

clay;
earth;
salt marshes;
slag, etc.

There is a hook for loading and a bulldozer for raking.

Description of those parts of the excavator

Using a YuMZ excavator, they develop small faces, create embankments, clear the territory and perform other installation work. This technique can be used as a crane or hydraulic hammer, a fork or a straight shovel.

The high quality of steel from which spare parts for excavator equipment are made is of great importance. Due to its high maneuverability, this equipment is in great demand in a wide variety of farms.

Initially, the YuMZ excavator was intended for use in construction and public utilities. After modernization, it became suitable for use in the agricultural industry.

These machines are still used in various farms, although they have already been discontinued.

The key to their success is their relatively small size, maneuverability combined with high productivity. And their low cost is another indisputable proof of their advantage over imported cars of the same class.

Specifications

The YuMZ-6 excavator is a descendant of the well-known MTZ-5 tractor.

Despite its small dimensions, this excavator operates at the level of larger and more powerful equipment.

The advantage of the unit, which makes it possible to optimize operation, is that the chassis is wheeled and not tracked. The rear wheels act as drive wheels, and the front wheels act as guides. The working surface of the wheel is equipped with pneumatic tires, which are excellent for working on loose or uneven surfaces.

The steering mechanism consists of a worm, a helical sector and a hydraulic booster.

Front non-driving axle of MTZ tractor

Hydraulic system

Includes two independent hydraulic drives with piston-type hydraulic cylinders. One of the drives is responsible for the operation of the bucket, handle and boom, the second is responsible for the operation of the rotating mechanism, outriggers and bulldozer. Both hydraulic drives have a common filling tank.

The hydraulic system includes a set of equipment:

oil pump;
filling tank;
oil filter;

Grab loader on an old YuMZ-6

Good afternoon

What does it take to make a child happy? I need my father to let me drive his tractor. What could be cooler? What if you don’t just steer, what if you control a loader?

My father worked on a YuMZ-6 tractor: he raked hay into windrows, transported hay, and plowed the villagers’ gardens in spring and autumn.

Once his YuMZ-6 was even used for corn harvesting: they attached a trailed forage harvester. I don't remember its model, but it was very old. They restored it because the KSK-100 couldn’t handle it (always under repair).

And often I went with my father.

One fine day, the authorities decided to re-equip this tractor. We decided to hang a grab loader on it for the winter.

This YuMZ-6 and a loader, only with forks

The fuel tank was moved forward and the rear window was removed. And it seems that not only the window, the entire rear wall of the cabin was removed (I don’t remember exactly) and replaced with another insert that was included with the loader. The sprung seat was removed and a sofa was put in its place, without a back, of course. Now it has become more convenient to ride with a passenger.

A free space formed behind the back where the loader controls were located. We arrive at the place, throw our legs back and there they are, the loader control levers. There were six of them, but I could be wrong. One controlled the rotation of the boom around its axis, two more controlled this boom (raising/lowering and bending the boom), the fourth lever was used to grab the load. Another pair of levers are designed to move the stops into the working position.

It was cool, I’m sitting behind these levers, a horse with a sleigh rides up, I grab some hay (or it was straw), and put the load into this sleigh. Simply unforgettable emotions!

The loader also had a blade at the front, which my father used to clear farm roads and village streets. Then spring came, the loader was dismantled from the tractor. And YuMZ returned to its usual work. For some reason, they only put the loader on it for one winter, and they didn’t do it again. Apparently it didn’t live up to expectations or there was no longer a need.

The PE-0.8 backhoe loader was initially installed on the MTZ-5 tractor. The PE-0.8A loader was designed for YuMZ-6. It could be used both for earthmoving work and as a loader. It can be used to load bulk materials, fertilizers, straw, manure, etc. The main elements of the loader: frame, blade, rotary column, boom, support jacks, hydraulic drives and replaceable working parts: claws (forks), bucket, hook and etc.. The next stage in the development of the loader was the PE-F-1 model.

Loader-excavator PE-F-1BM

Yes, there were times. Not long ago, I returned to the places where these actions took place. If anyone doesn’t know that there were farms there, they’ll never guess: everything is flat and overgrown with nettles. Only a couple of columns indicate that there was something there. Birch trees grow in the adjacent fields. And the village street is no longer a village street, but just a street. Everything was overgrown, not a single living soul, the poplars dried up, the fences fell, the houses were dismantled, and what they didn’t have time to dismantle was burned during one of the fires: someone set fire to the grass, and the grass there was as tall as a man, the fire swept through, no one noticed!

That's all!!! I recommend watching the articles on the channel

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.

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.

Excavator equipment

The machine can be equipped with the following equipment:

a variety of buckets depending on their purpose;
hydraulic hammer;
tooth for loosening;
grabs of various sizes.

The design of the machine allows you to work with replaceable equipment.

The ripper tooth is used for loosening dense or frozen soil, uprooting stumps and roots, opening paving stones and road surfaces, etc.

Using a hydraulic hammer, you can crush concrete floors, walls of buildings, loosen soil, etc.

A grab is equipped with a backhoe loader for loading bulk materials.

Existing modifications of the YuMZ excavator

The Southern Machine-Building Plant has developed several modifications of the YuMZ-6 tractor:

YuMZ-6L is distinguished by a rounded radiator grille; outwardly the car resembled the MTZ-50. Has a starting motor.
YuMZ-6AL had a rectangular hood, a steering rack adjustable in height and tilt. The appearance of the dashboard was changed and improvements were made to the design of the brake system.
YuMZ-6AK with an adjustable hydraulic system (power and position control), with improved visibility of the cabin. It was first produced in 1978.
YuMZ-6KL. In this model, the manufacturer installed standard mounts for a bulldozer and an excavator, and this particular modification is considered an excavator.

The YuMZ-6KL model eventually became the base model, and an agricultural machine was developed on its basis. A tractor based on the YuMZ-6KL model began to be used for leveling and field preparation, sowing and harvesting, and for loading for transportation.

Excavators of this type are still successfully used in construction and utility work, in agriculture for row cropping and loading and unloading operations, and in other industries for laying pipelines, cable lines, digging pits and other work.
