Comparing YuMZ and MTZ: advantages and disadvantages

Not guys. YuMZ is real shit compared to MTZ. I competed with YuMZ at MTZ, and we went to the forest and participated in haymaking, where your YuMZ ended up, where YuMZ smoke doesn’t get into the chimney, MTZ at least gives a shit, and for repairs, for All 30 years at MTZ, among the serious breakdowns, I only changed the reverse gear and that’s all

So I became the owner of this tractor. I took it from a person who didn’t service it on time, but seemed to keep the bundles safe (not all of them are true).

Minus - the engine oil was black, the oil filter was clogged, the centrifuge did not work. Replaced with regular diesel. oil, 40 rubles per liter, sold at gas stations. (by the way, it needs to be changed every 250 hours, according to the book). With new oil the pressure is 3+, when hot 2+, at the lowest speeds and hot 2-. There are no electrics at all, it will need to be restored. But judging by the diagram, all electrical equipment consists of lighting devices. Well, no big deal. The rubber is all bald and has radial cracks here and there.

pros

- inherent in any tractor - cross-country ability.
I drove about 12 kilometers in a day. On clay and mud. Where the rear wheels are slipping (the tires are almost zero), I turned on the lock and immediately came out. Puddles and ruts of at least 30-40cm are no longer a problem! Autumn has passed, the roads in the forests are terrible, but at least there’s nothing on the tractor. I came across one swamp on the road, 5-6 wheel tracks wide, so many paths were made because everyone goes around this road swamp (UAZ, etc.) - I drove along the most hopeless rut, even for trucks, probably - well, I left as I entered - even with the gas pedal didn’t work Like setting the machine to 800 or 1000 rpm, turning on the second one, it goes and goes, I only held the lock with my heel. Nivovody set up camp nearby, because They can’t drive further - from where I left, they just sighed heavily in the wake Article on the topic: Ford Explorer 2016 owner reviews
It starts from the launcher, but I learned better from rolling, it’s more convenient than pulling the starter.

I met YuMZ-6 by chance. I bought it as a decommissioned piece of equipment for pennies. It took a couple of months to recover. A couple of spare parts are new, the rest I found in advertisements for used ones. Now he is my indispensable assistant in housekeeping.

pros

:
Simple Soviet tractor, sufficient power, simple design, long service life
Cons

:
The vibration is not weak when plowing, the seat is not the most comfortable, I still haven’t adjusted the gear shift, it’s tight.
Since 2007 I have been the owner of a YuMZ-6 1982 model. In a previous life, he was an excavator, and then he was converted into an ordinary tractor. I use it for plowing, cultivation, planting, making hay and firewood. In general, he helps me with almost everything. There is no power steering, but the steering wheel is easy to turn. In the future, of course, I am going to switch to hydraulic control with a dispenser. Engine – D-65.

There are no serious comments about him. I will say more, in cold weather it is easier to start than many other engines. The fuel tank is located at the front. In the cabin, under the seat, there is a starter battery for the starting engine and a tool box. There have been no problems with the clutch in three years of operation (I try not to burn it). The box also works properly.

The only thing is that the locking mechanism has recently been replaced. By the way, I didn’t have to remove the cabin for this - I did everything through the hatch. Of course, there are problems with spare parts - they are often out of stock. But they can bring anything you want to order. That's why I don't worry too much about it. In principle, the tractor suits me. I have never regretted buying it. The only sad thing is that you can’t put a front drive axle on it.

Advantages:

Yumz itself is a very reliable tractor. Its big disadvantage, as many have noticed, is that it does not have a front end. The front end helps a lot in the forest or in the field when you plow, for example. The checkpoint is also a minus. The tractor is very slow compared to MTZ. Speed ​​may not play a big role if the tractor is working in the forest. But when transporting any cargo, this significant drawback immediately comes to the fore. It is also now difficult to get spare parts for it. The weak point is the clutch. I advise you to buy this tractor if you are limited in money. Why essentially buy MTZ for 250 thousand if you can buy UMZ for 90 thousand (if you are limited in money, I repeat).

Advantages:

savings easy start

no front axle

This year I bought a not new but quite passable tractor because I decided to start collecting firewood not only for myself but also for the population, and one car was not enough. What can I say about this technique from my conclusions: easy starting due to the decompressor, fuel efficiency, high torque due to the large mass. The downside is that the locking jumps, but I managed to adjust the traction and there is no front axle, which makes it difficult to work in the forest, but otherwise it’s all right.

The lineup

The range of tractors from YuMZ was truly extensive. Conventionally, it can be divided into two categories - the original MTZ 5 LS and YuMZ 6, which included certain modifications of the machines:

• MTZ-5LS “Belarus” - under this brand the world saw the original model MTZ-5LS;
• YuMZ-6L “Belarus”;
• YuMZ-6M “Belarus” (rounded radiator grille, as on the 6L modifications);
• YuMZ-6AL;
• YuMZ-6AM (like the AL, it was distinguished by a rectangular hood, a more comfortable steering wheel, and an improved instrument panel);
• YuMZ-6KM;
• YuMZ-6KL (like the 6 KM models, improved visibility of the cabin, without an agricultural attachment system, adapted for working with equipment for a bulldozer, excavator).

In the designation abbreviation, the letter “L” means the presence of a starting motor, and the letter “M” means the presence of an electric starter.

The basis for the YuMZ 6 and their modifications was the MTZ-5. The production of the cars finally ceased in 2001. Since then, only used models of YuMZ tractors can be found in public and private farms.

It is well known that in 1974 the documentation for the production of YuMZ6 was sold to Sweden. It was this tractor that served as the basis for the development of the future Volvo VM700 tractor.

MTZ 82

The model, developed back in the 70s of the last century, is still popular today. Unlike the MTZ 80, on the basis of which the 82nd series was created, the vehicle received two drive axles, which made it possible to expand its functionality. Subsequently, the MTZ 82 was modernized several times, so today buyers often have doubts which MTZ 82 tractor is considered the best.

The 82nd model itself is presented in 3 modifications:

1. Wheeled universal row-crop machine of 1.4 traction class. Used in agriculture, municipal services, forestry, road work and construction. It is considered an all-wheel drive tractor with a plug-in front drive axle and a 4x4 wheel arrangement. Semi-frame construction. The base is equipped with a friction single-disc permanently closed clutch.
2. 82R. Designed for working in rice fields. Unlike the base model 82.1, this tractor is equipped with wide-profile low-pressure tires with star hooks, a portal front and rear axle. This machine also has increased agricultural clearance.
3. 82N. Model for farmland in mountainous areas. A machine with a lower center of gravity, with enhanced lateral and longitudinal stability. The tractor is equipped with a modernized PTO, as well as wheels of reduced diameter.

• spring-loaded driver's seat;
• steering device, with the ability to change the height and angle of inclination;
• control levers;
• clutch and brake pedals;
• dashboard, on which sensors are located to monitor the functionality of all systems and working parts.

The cabin is equipped with large rear-view mirrors and sun protection elements. The heating device and fans are responsible for climate control. The package includes a water tank and a device for securing it in the cabin.

High-quality equipment for your tasks

The Minsk Tractor Plant and the Southern Machine-Building Plant are constantly improving the quality of their products in accordance with the growing demands of consumers. The main improvement of tractor technology occurs in several areas:

• Improvement of technical characteristics. The latest models of special equipment have reduced fuel consumption with a concomitant increase in power.
• Increased cabin comfort.
• Simplifying equipment maintenance and increasing reliability. Existing models are regularly improved by introducing new changes to the design of units, components and parts.

Engine YuMZ-6

The tractors were produced equipped with two types of diesel power plants D65 and D-241-71. Early versions of the tractor were equipped with a D-241-71 diesel engine with a power of 45.6 horsepower and a displacement of 4.75 liters. The base for the tractor was the 5-liter D-65 engine with a power of 60 horses. This 4-stroke 4-cylinder engine with a direct fuel injection system had an in-line vertical arrangement of cylinders. The engine is started by a starting device or an electric starter.

General information and history

YuMZ-6 is a wheeled tractor for industrial and agricultural purposes, which is produced at. It began to be produced from 1970 to 2001.

This tractor was created on the basis of the MTZ-5, which was also produced at this plant. There is some similarity with MTZ-50, but still YuMZ left more similarities with MTZ-5. In the USSR, the YuMZ-6 was considered the simplest and most reliable tractor. By the way, Sweden bought the rights to produce this tractor and, having modernized the design, created their own Volvo BM-700 tractor.

There are four modifications of the tractor.

YuMZ-6 was produced from 1970 to 1978.

YuMZ-6A was produced from 1978 to 1986.

YuMZ-6K - 1986-1993.

YuMZ-6AK - 1993 - 2001

In addition, the modifications also included the letters L and M, which corresponded to how the diesel engine was started, M-electric starter or L-starter.

Specifications

The tractor weighs 3400 kg. And the dimensions are 4.06 x 1.8 5 x 2.75 meters. The tractor belongs to traction class 1.4

There are two types of engine.

The first models were equipped with four-cylinder D-65 engines with a capacity of 5 liters and a power of 60 horses.

A more economical option is the D242-71, which has a smaller displacement and only 46 horsepower.

Average fuel consumption is 245 g/kW per hour.

Advantages and disadvantages of the unit

The tractor was created based on the already more or less advanced machine of that time, the MTZ-5, so there was no particular need to change anything radically. However, there are certain differences.

Article on the topic: Metabo kgs 216 m owner reviews

The tractor is characterized by durability and high quality of all components. The design is such that it is quite easy to repair. An important point is interchangeability. Here it reaches 70% of all units. In addition, the tractor is unpretentious to fuel and oils. All this makes it economical and easy to use.

And if we take the working conditions for a tractor driver, then everything was thought out quite professionally at the level of ergonomics, comfort and design. Moreover, the unit was not inferior in these indicators to Western analogues of that time.

Of course, many people also note shortcomings. This is primarily a shifted center of gravity. It is located too high, so it is dangerous for the tractor to operate on slopes of more than 10 degrees. But this can also be solved by increasing the track to its maximum of 180 cm.

There is also unsatisfactory fixation of maximum speeds on the gearbox. This is most noticeable when driving the tractor from trailers on uneven surfaces.

There may also be problems with the rigidity of the tractor chassis suspension. There is also a decrease in tractor operating time at low and idle speeds.

But all these shortcomings can be easily overcome if the performance characteristics are not violated.

Many people note that all the components and assemblies on old tractors of this model have long expired, but still continue to function. In addition, they can be easily replaced in your workshop, where they can be restored. But all of these significantly lack the tractor's front drive axle.

A normal unit can be purchased for 3 thousand.e. or even more expensive. And given that the tractor has not been produced since 2001, now you can only purchase a used unit. But if you take into account the interchangeability of many components, it will not be difficult to repair if necessary.

Results

The unit is quite necessary and easy to use. It is capable of hauling three tons of coal with a trailer. It can be used both for yourself and for earning money. It is easy to repair, it is not picky about fuel, which is very important in conditions of low-quality fuel.

In my opinion, the YuMZ-6 tractor is in all respects not inferior to modern models. I’ve been using the car since back in 1983, all components and assemblies have exceeded their service life with a large margin, individual parts are successfully restored even in a home workshop. The machine easily pulls a double-furrow plow and pulls up a tractor trailer with three tons of coal. The only thing this tractor lacks is a driven front axle. Garik Nikolaevich

YUMZ, written off and bought on occasion for little money, restored it with my own hands. I had to buy some spare parts, but the main range is used. As a result, I have a reliable assistant on the farm and a constant extra income. Mikhail Vasilievich

Features of operation and maintenance

The YuMZ tractor is operated in compliance with the following rules:

• gear shifting is carried out only when the clutch is disengaged;
• engine idling should not exceed 15 minutes;
• after reducing the load, let the engine run for several minutes in low load mode, and only then turn it off;
• when the tractor is moving, only one person can be seated in the cabin;
• regularly lubricate mechanisms and key components of the tractor, use universal lubricant (with special markings for different seasons);
• Activate the starting engine only when the gearshift lever is in neutral;
• for the starting engine it is allowed to use gasoline A76, A72, in the absence of such - A92, to create a combustible mixture for the operation of the PD, mix 20 parts of gasoline and one part of oil for diesel engines, and then pour into the starting engine;
• the fuel needs to sit for about 48 hours before being poured into the diesel engine tank;
• oil for DD - GOST 305-82, oil for PD - according to GOST 2084-77;
• for the gearbox - TEP-15 or TAP-15V.

Maintenance of the YuMZ6 tractor involves monitoring the status of the following parameters:

• tire pressure;
• control of the rear linkage mechanism;
• fuel level;
• control of the movement of all mechanisms, the condition of fastenings;
• engine operation;
• seasonal maintenance as necessary;
• once a year - prevention of gearbox breakdowns.

For new models, running-in is required to increase the life of the tractor so that all parts get used and fit into the grooves. This procedure takes about 6-8 hours, during which the tractor is operated at 50% of its power. Upon completion of the procedure, it is necessary to change the engine oil.

For used tractors, running-in is not necessary.

At the end of the operating season, the tractor must be mothballed. It must be cleaned, placed in a dry place, the oil drained, the spark plug wires disconnected and the parts lubricated to prevent corrosion from forming.

Main malfunctions of YuMZ tractors and their elimination

Next, we will look at the main malfunctions that may arise during the operation of YuMZ tractors, as well as ways to eliminate them:

• The engine does not start - perhaps it is not warmed up enough or the fuel filters are clogged;
• the diesel engine operates intermittently and does not reach full power - you should check the fuel filter and the condition of the fuel pump;
• the starting engine is acting up - check the carburetor bolts, replace the gasket, check the condition of the spark plug, if necessary, clean the spark plug or replace it;
• the attachment does not stay raised - replace the seals, examine the condition of the hose connectors.

Device and technical characteristics

The YuMZ-6 tractor, according to its technical characteristics, belongs to the category of machines of the 1.4 ton traction class. The design of the tractor is classic, the front axle and engine are mounted on a semi-frame, rigidly fixed to the clutch housing and gearbox. The box housing is part of the power structure of the machine. The YuMZ-6 tractor uses a 2-flow clutch, which allows for separate control of the drive shaft of attachments.

The equipped YuMZ-6A tractor weighs from 3.4 to 3.9 tons. The weight of the machine depends on the modification, the list of attachments and the type of power unit. To change the weight distribution, install additional weights.

Engine

The tractor was equipped with 2 types of diesel engines:

• 60-horsepower YuMZ D-65 with a displacement of 4940 cm³;
• 62-horsepower D-242 with a displacement of 4750 cm³.

Both engines are 4-cylinder and equipped with liquid cooling. The lubrication system is forced, the oil supply and the pump are located in the engine crankcase. The engines do not have a turbocharger; a mechanical pump with a centrifugal regulator is used for fuel injection.

The fuel consumption of the YuMZ-6 depends on the condition of the dosing equipment and the nature of the work performed. The factory consumption value per hour is 5.6 liters at idle. The cockerel tractor (with an excavator boom) consumes up to 14.4 liters of diesel fuel per hour.

To start the power plant, a PD-10 gasoline engine or an electric starter is used. The power of the PD-10 engine is 10 hp. The type of start is reflected in the description of the modification - L (gasoline starter) or M (electric). Engine repair does not require special equipment and equipment and can be carried out in auto repair shops.

Transmission

The tractor uses a mechanical 5-speed gearbox. To transmit torque to the YuMZ gearbox, a single-disc clutch is used. The gearbox and clutch are controlled from the operator's cabin. A gear shift diagram is located next to the lever, making the operator's work easier.

The rear axle of the car is equipped with a differential with a mechanical locking system.

The lock is activated by pressing the pedal; when the pedal is released, the differential returns to its original state.

YuMZ vehicles with a front drive axle are assembled by owners using elements from T-40 wheeled tractors. From the T-40, a front axle, a transfer gearbox and a cardan drive are used. The 4x4 drive is realized from the 2nd gear gear mounted on the secondary shaft of the gearbox. The FDA (front drive axle) is engaged using a separate lever.

Chassis

The tractor is equipped with a swing-type front beam. Retractable elements used to adjust the track are mounted at the ends of the beam. The beam controls the front wheels. Steering wheel of the YuMZ-6 of early releases of the mechanical diagram. The later version of the tractor is equipped with hydraulic power steering.

The rear wheels are mounted on the gearbox housing without suspension. The track is adjusted by moving the hub along the splines of the axle shafts. The tire pressure on the rear axle is low. This improves the machine's maneuverability and also reduces vibrations transmitted to the tractor.

Hydraulics

The machine uses a separate hydraulic system, which allows you to control several units simultaneously. The characteristics of the tractor allow the use of various agricultural and industrial equipment. The source of pressure is a gear pump located on the engine. The pump has a capacity of 44-49 l/min at a pressure of 20 MPa.

The tractor is equipped with main and remote cylinders designed for direct control of the hitch. Installation of equipment with power drive from the shaft is allowed. The shaft is located on the back of the box and has 1 rotation speed (540 rpm).

Electrics

The YuMZ-6 tractor is equipped with a direct current electrical system. The electrical circuit is based on connecting the negative terminal of the battery, electrical wiring and instruments to the machine body. To distinguish the wires, different color markings of insulation are used. The tractor has 3 fuse blocks installed in the instrument panel. Each block is designed for 4 fuse links. There is a spare fuse in the central unit.

Article on the topic: Nissan Juke reviews from CVT owners

The operating voltage is 12 V. The current sources are the generator (belt driven from the engine crankshaft) and the battery. On cars with an electric starter, a battery of increased capacity is installed (up to 215 A*h instead of 50 A*h). The electrical circuit of cars with gasoline and electric starters is different, since the gasoline engine is equipped with a separate ignition system and a small-sized electric starter.

Cabin

The machines use a 1-seat metal cabin, equipped with 2 swing doors. At the base of the cabin there is a power frame that protects the operator from injury when the tractor overturns. The cabin is equipped with noise and vibration protection and glass with a heat-insulating coating. The windshield and rear window are installed in folding frames. A wiper and washer system are installed to clean the windshield.

The cabin floor has removable hatches for servicing the gearbox. The operator's seat is sprung with a torsion bar suspension and equipped with a seat belt. The seat is adjusted according to the weight of the operator, as well as the distance to the pedals and the angle of the backrest. The cabin is equipped with a heater installed on the floor. The heater is connected to the engine cooling system.

Comparison of tractor parameters

Let's look at how the cars differ. To understand which is better than YuMZ or MTZ, you need to pay attention to the following indicators:

The engine power is 62 hp, which allows you to install various attachments on the tractor.

Each of the models has a portal front axle; only the MTZ has a spring suspension installed on its wheels, which is a telescopic type. YuMZ has a rigid suspension, which affects the movement and level of comfort while driving the car.

YuMZ has a double-flow clutch installed, which has a higher level of reliability, lower wear and longer operation, compared to the single-flow clutch found at MTZ.

Let's compare the parameters of YuMZ versus MTZ and find out all the differences. The equipment of the Southern Machine-Building Plant is equipped with an improved gearbox and gearbox with 1 lever. The Minsk machine has 2 levers, each one controls a separate unit.

The southern model has a PTO drive, which switches to different modes - synchronous and two-speed (independent). The Minsk unit also has a two-speed drive system, but it is of the independent type.

The Belarus tractor is equipped with a high-quality hydraulic linkage system, which is automatically adjusted. This allows you to change the plowing mode, including depth, and change the amount of coupled weight. Such functions are not provided on the YuTZ unit, so the Minsk model is better suited for agricultural work, rather than the machine from the Southern Machine-Building Plant. Although the southern design has an improved operator's cab for greater comfort, a machine with a modern control system is better suited for field work. This will allow you to install any equipment and drive on difficult soils.

Tractors have continuous track adjustment systems, which are located at the rear wheels. Steering columns on YuMZ allow adjustment in height and steering angle, as a result of which tractor drivers independently select a convenient and comfortable control mode. Most Belarus models do not have such a function; it is provided only on the MTZ-80 model.

Thus, farmers must decide for themselves which tractor to buy. It is necessary to study the description of each model in detail before spending money on purchasing special equipment. Units that differ in technical characteristics must be studied both according to the model range and user reviews.

Both units are reliable, economical and unpretentious equipment that will not let you down during work in the field, city, construction site or other sites.
