MTZ 320: technical characteristics and features

The Belarus-320.04 minitractor is a multi-purpose wheeled station wagon that allows you to perform a lot of different operations in the industrial, municipal and agricultural fields. The model can be equipped with various attachments depending on the type of work, but it is worth highlighting that the range of equipment offered includes a huge number of variations and types.

This model belongs to the 0.6 traction class of agricultural special equipment. In the standard version, the minitractor has a four-by-four wheel arrangement, with the front axle being the drive axle. Due to the locked center differential of the drive wheels and fairly high ground clearance, the Belarus-320.04 can overcome very large obstacles and work on various categories of soil.

The distinctive features of all MTZ mini tractors are still a high level of maintainability, increased reliability and simple design, unpretentiousness, availability of spare parts and fairly good technical and operational performance. All this is also characteristic of the Belarus-320.04 model. Due to this, the equipment has gained great popularity not only in the Russian market, but also in many CIS countries. Currently, this machine is one of the most leading among the products produced by the Minsk Tractor Plant.

The standard configuration, like all others, uses a diesel power plant with a capacity of 26.5 kilowatts or 36 horsepower. For its class, this figure is rightfully the highest, since this power is quite enough to perform very labor-intensive tasks.

Purpose

The Belarus-320.04 minitractor is most popular on farms, as it allows you to carry out a fairly large amount of work in a short period of time. Together with attachments, the model performs such work as preparing feed, planting and digging up tuber crops, pre-sowing and main cultivation of the fertile soil layer, inter-row cultivation, sowing grain crops, as well as harvesting the grown crop and transporting it to the storage site.

In addition, the equipment is also in demand in livestock farming, where it is mainly used to move any cargo, in particular feed.

Application

The compact tractor MTZ-320 is used with mounted and trailed equipment. The universal machine is used in agriculture, as well as industry, construction, and public utilities. Low price and operating costs make this tractor a good choice for small businesses.

Device Features

The Belarus-320.04 minitractor has many different advantages, which are what allowed the equipment to stand out among similar models. First of all, the machine has fairly compact overall dimensions and a very affordable price. It should be noted that the established price tag fully justifies the build quality and reliability of the equipment as a whole. The mini tractor was first introduced to Russian markets quite a long time ago, and during all this time the model has gained very great popularity in private and rural households. The key advantage of the Belarus-320.04 minitractor is its high cross-country ability. The machine is able to easily move on viscous and loose soils, which is especially valued among Russian consumers.

The frame of this model consists of a half-frame, gearbox, axle housings of the rear and front wheels mounted on the half-frame, as well as a clutch housing. On the supporting frame of the equipment, a driver’s cabin was installed on vibration isolators, which provide increased comfort, since these elements help reduce shaking and absorb vibrations. The cabin itself is sealed, has a rigid protective awning frame or a special protective arc. These elements are included in the mini tractor package at the request of the consumer. In any version of the tractor, the cabin is equipped with rear-view mirrors and a single seat, which has several adjustment modes.

The track of the front and rear axles, depending on the work requirements, can take on different values. The steering mechanism is equipped with a hydraulic booster, providing increased operating comfort. The steering column includes two adjustment modes, allowing the operator to select the desired angle and height.

The power take-off mechanism, located at the rear of the minitractor structure, ensures the transfer of the full power of the power unit to the mechanical devices used. The PTO has two two-speed drives, which allows for greater efficiency when working with additional equipment. The equipment can be equipped with a variety of mechanisms that allow the use of trailed and stationary units.

The manufacturer offers as additional equipment:

1. Front power take-off mechanism, which occupies a place in the front of the semi-frame. It turns off if the clutch has been completely stopped. The same thing happens with inclusion.
2. A towing fork designed for use with trailers and semi-trailers. It should be noted that in the standard configuration the minitractor is not capable of working with trailed implements.
3. A pneumatic system used to operate trailer and semi-trailer brakes.
4. Several ballast weights, giving a total weight of 175 kilograms. This addition is used to improve handling, longitudinal stability and traction characteristics.

Compared to similar Chinese-made models, the Belarus-320.04 minitractor is the most reliable. Another important advantage can rightfully be called:

• Wide functionality of technology.
• Economical in operation and maintenance.
• Increased levels of performance and reliability.
• A wide range of additional trailed, stationary and mounted devices. But besides all this and this mini tractor, there is a downside. Firstly, many owners find it difficult to start the power plant at low air temperatures. Often the unit refuses to work at temperatures of minus 30 degrees Celsius and minus 35 degrees Celsius. Secondly, sometimes there are malfunctions in the transmission system, in particular the clutch. And thirdly, according to some owners, the car turned out to be clumsy and slow.

Reliability

The Belarus-320.04 minitractor is characterized by increased reliability, unless, of course, we take into account the problems presented above. The main structural elements have a very long service life. The lifting capacity of the equipment is 1100 kilograms. This means that the equipment can use fairly heavy units and work under high loads without any breakdowns.

Repair features

The owner will not go broke on the maintenance of this machine, because there are two reasons for this:

1. Spare parts, consumables and many other parts can be purchased at a very affordable cost.
2. Some components of the mini tractor are unified with many other tractors of the MTZ brand.

The device of the Belarus mini-tractor

The MTZ-320 is equipped with several different engines. One of them is the Italian Lombardini power unit, produced in Estonia. Its volume is 7.2 l, power 36 hp. The name of this motor is LDW 1503 NR.

Tractors with MMZ (Minsk Motor Plant) engines are also produced.

• Transmission and chassis

A large number of gears (16 forward and 8 reverse) and a reduction gear allow you to vary the traction over a very wide range, so you can use the tractor in a wide variety of conditions.

The front axle is portal, which improves its geometric cross-country ability. The rear axle is equipped with a differential lock to increase stability on slippery surfaces.

Also in the MTZ-320 it is possible to change the tractor track width.

• Cabin

The operator's cabin is equipped with heating and ventilation systems. Controls are within easy reach for the operator. The driver can adjust the steering column.

MTZ-320 operators note good visibility in all directions from the operator. When developing the machine, the designers thought about noise level and operator comfort. The cabin also has a rear-view mirror, sun visor, first aid kit and space for a fire extinguisher.

• Electrical equipment

The MTZ-320 tractor is equipped with a 630 W generator. A battery with a capacity of 88 ampere hours produces a voltage of 12V.

Owner reviews

• This mini tractor is used not only in the garden, but we also do work on it in the autumn on a fairly large field. In my opinion, the technique is very effective for plowing and planting, since processing the area does not take a long time. At the moment, everything is working properly and does not even raise suspicions about a possible breakdown.
• This machine has been in use on the field for quite some time. Last year, Belarus-320 was used in the construction of a bathhouse, where, by the way, it helped a lot with the delivery of building materials. The car drives confidently on soft ground. The same thing applies to working with a three-furrow plow.

History of creation

The decision to create the Vladimir Tractor Plant was made in 1943, at the height of the Great Patriotic War.

The construction of the plant was a real labor feat; in these difficult years for the country, it was necessary to build not only the plant itself, but also the entire infrastructure, as well as train qualified personnel!

In the middle of the summer of 1944, the first Universal U-2 tractors were ready. By April 1945, another 500 cars had been assembled, and on the 24th of the same month a solemn meeting was held, at which it was decided to consider this day the birthday of the plant. For the first ten years, the plant produced Universal tractors. These were simple and cheap cars with metal wheels and a carburetor engine. Tractor T-25 model 1966 In 1955, a new tractor DT-24 was created, a new diesel engine was installed on it, and the wheels were shod with rubber tires. A year later, 10,000 cars were produced. A further, significant step in the development of the plant in 1958 was the start of mass production of the new T-28 “Vladimirets”. This model received a gold medal and was awarded first prize at the World Exhibition in Brussels. Over the entire period, more than 250 thousand of these machines were assembled. In 1972, production of the T-25 tractor, produced in Kharkov since 1966, was transferred to VTZ from the Kharkov plant, and a year later it was replaced by a completely updated T-25A, which became the calling card of the plant for many years! It is the T-25A, and not its predecessor, that is considered the base model for all future modifications.
