LTZ-155 tractor. Description, specifications, maintenance, video, reviews
Universal tractor for row crops LTZ 155 with an integrated circuit is an innovative development for its time. Integral scheme implies non-standard arrangement of nodes and units to solve certain problems – for example, to reduce the overall dimensions or increase productivity. Thanks to the efforts of the designers, the LTZ 155 has taken a special place in the history of domestic agricultural machinery. More precisely, it would have taken a special place, if its history had developed more cheaply. At the moment, in addition to production.
History of the creation of the tractor LTZ-155
History of the creation of the Lipetsk tractor began in the pre-war years with the machine-building plant “Stankostroy”, which was built in 1932-1936. A whole residential area with well-developed infrastructure was created near the production. At the beginning of 1940s Stankostroy was already an important town-forming enterprise.
In 1943 at the height of the Great Patriotic War the country experienced an acute shortage of tracked tractors both at the front and in the agriculture. At that time it was decided to build the tractor plant “Lipetsker” on the production facilities of “Stankostroy” enterprise.
Simultaneously with construction and reconstruction works, LTZ team was working on the first “Kirovets-35-Rauptractor”, which was ready for use on June 1, 1944. This was the first vehicle of LTZ brand that came off the assembly line in various models and modifications after more than a million and a half of its counterparts.
During its existence the plant has mastered the production of caterpillar tractors KD and KDP-35, T-38M for serial crops. There was mastered the production of versatile LTZ-55 with wheels, famous T-40, LTZ-60.
The crowning achievement of the Lipetsk tractor industry was the LTZ-155, the chief designer of which was Alexander Durmanov. It was designed and put into production in 1988, but went into mass production only in 1995. This tractor is the 2nd traction class, integrated circuit, in many ways ahead of its time and proved its unique versatility and excellent performance characteristics.
But, unfortunately, like many outstanding developments in our country, it was underestimated. Although the car was made of iron and went into mass production, the output was small and perished in the ruin of the 1990s. The last point in the sad history of this unique truck was in 2004, when bankruptcy was declared and the entire LTZ series was withdrawn from production.
Popular Manufacturer
Depending on the manufacturer and model of the device, the technical characteristics also change. The logging tractor is produced by many special-purpose vehicles. If we talk about the Russian market, both domestic and foreign assemblies are offered here.
Among Russian tractors in demand are products, Lespozhmash (Barnaul plant), Kirov plant, Onega tractor plant, and others. Imported tractors of this type include such brands as John Dir, Velte, Caterpillar, LKT, etc.
In order to make the work of garbage equipment more understandable, consider the different models of such machines.

LTZ-155 – all-wheel drive machine with wide wheels of the same diameter. It can be equipped with twin narrow wheels for inter-row cultivation. In this case, the row passes between the sparks.
The rear axle with balancing deviates relative to the body by 11 degrees. This allows you to copy the terrain separately with the rear and front implements. The tractor’s weight is distributed as follows: 60% on the front axle and 40% on the rear. Such weight is distributed on all four wheels when working with tractive load.
The LTZ-155 tractor cabin
The tractor is equipped with a frame single-place cab mounted on the chassis for four insulators-emitters. The cab is located in the center of the base and can be a working equipment on a specially equipped platform.
It is sealed inside with soundproofing materials. It is equipped with forced ventilation and heating systems, thanks to which the tractor will work throughout the year. An air conditioner can be installed as an option.
The main driver’s seat is vertically and horizontally adjustable and weight-adjustable. In addition to the driver, there is also a folding passenger seat.
The control panel is equipped with an automatic system for controlling the operation of tractor systems and assemblies. Control elements are maximally convenient for the operator and can be converted to work in reverse mode.
Operating of LTZ-155 tractor
The main distinguishing feature of our hero is a unique tractor control scheme. Here the designer surpassed the LTZ under the leadership of Alexander Durnimanov, creating a tractor with all four wheels steering. This allowed the machine to perform maneuvers previously inaccessible to vehicles of this class.
For the LTZ-155 there were four options to turn:
- Turn only the wheels of the front axle;
- Turn only the rear axle;
- Rear and front wheels turn in the same direction (this maneuver was called “crabbing”);
- The front and rear wheels turned in opposite directions (in this case, the rear wheels copied the front track).
Wheel control of the front axle is hydraulic, of the rear hydromechanical with a tracking effect, the signal to the tracking device from the front axle.
Tractor control post is quickly reversible. This allowed the tractor to successfully perform both front and rear tasks.
Only after the launch of LTZ-155 series in Europe began to develop tractors with similar control system. And in 2004, when the production of LTZ-155 was already discontinued, Uralvagonzavod launched a tractor with identical control system RT-M-160.
device
The LTZ-155 has a unique feature that sets it apart from other representatives of this class. The tractor design allows to make turns with front and rear wheels. When performing various tasks in difficult conditions, it gives the technique unusual advantages. The tractor has steerable and drive wheels of the same size and a half-closed frame.
The model is equipped with a reliable transmission, whose mechanical joints and parts are made of high-quality materials. This keeps maintenance costs to a minimum. High technical characteristics of LTZ-155 nodes exclude regular replacement of worn parts. This increases the service life of the tractor components.
The equipment is equipped with a suspension device with an increased safety margin. As a result, this model is not afraid of the constant heavy loads. The leading device of LTZ-155 is the rear axle support.
The tractor wheels are turned by the steering wheel. The synchronous drive of wheels is carried out with the help of differential gear with electric control interlock and self-locking differential of the front axle.
The vehicle is equipped with a single cab with heating and ventilation systems, which allows to work in any season and weather conditions. The cab of LTZ-155 is equipped with a sunroof and side-opening glass that provides natural ventilation.
The main characteristics of the tractor are:
- good visibility and fast language rotary mail;
- high cross-country capability and a large loading capacity;
- a significant number of pneumatic, electric and hydraulic power units;
- Placement of implements and agricultural machinery directly on the tractor in front and behind;
- Possibility of simultaneous activation of the working elements.
Price of new and used
The LTZ-155 is currently discontinued, so there are only used tractor options on the market. The cost ranges from 135000 (running version) to 800000 (variants of the last years of production or after a complete overhaul).
analogues
There are practically no analogues of the LTZ-155. MTZ-82 tractor has similar technical characteristics.
Hydraulics and trailer system of LTZ-155 tractor
The tractor is equipped with a separate hydraulic system of agent type, which provides regulation of position, power, height and mixed control on the rear hitch. Agricultural implements arrangement. The task is also equipped with hydraulic control of the power to hitch the weight of the implements.
There are 4 pairs of independent hydraulic outlets for remote hydraulic cylinders and other hydraulic units. Front and rear problems as well as attachment and hitch hydraulics are controlled by the operator from the cab.
Both rear and front attachments on the tractor are three-point linkage. The two handicappers differ in places and method of attachment of equipment only in terms of carrying capacity. For the front one 2,500 kg, for the rear one 5,000 kg.
Both folding units are equipped with a mechanical transport linkage limiter, automatic bag and remote control.
Operation of LTZ-155 tractor
LTZ-155 tractors work effectively with the vast majority of agricultural equipment created for both MTZ-82 class machines and more powerful ones, such as T-150K. It can be easily coupled with a 4-hulled plough, coupling with a pair of cultivators KPS-4, three C3-3,6 seeders for sowing cereals, beams LDG-10 and other equipment.
The tractor has shown the best performance compared with counterparts in the cultivation of various row crops by wide-cut and cleaver machines.
Let us analyze the advantages and disadvantages of these machines.
Undeniable advantages are:
- Simultaneous placement of equipment on the front and rear linkage, as well as on a special place behind the cab. Four drives for simultaneous activation of the working elements of the placed equipment;
- The control post is quickly reversible;
- Gear shifting in idle range;
- Best maneuverability in its class.
It would seem, what could be the disadvantages of such a unique machine, but it was not without a fly in the ointment. And the reason for that to a large extent was the human factor.
The main years of the tractor production were in the 90s. Those were the years of general settling and confusion, which could not but affect the quality of assembly. In addition, by this time the plant was slowly dying.
As a result: Much of the machinery on the farm was defective, factory defective, and was failing quickly.
The lack of spare parts could also be considered a significant disadvantage. The machine has long been adjusted, and the installation has not worked for more than ten years.
I would like to note that when Uralvagonzavod gave the tractor a second life in the form of RT-M-160, serious work on the errors and corrected many design flaws.
Feedback from the owners
- Mikhail, Kaliningrad. Very productive and at the same time cheap tractor. It is very technological for its time and now it is just actual against the background of some modern models. Simple design, compact size, availability of front and rear attachments, good cross-country ability and wide glazing surface for these and many other advantages we very much appreciate the tractor LTZ-155. The machine has been used in our farm for more than 15 years. It is possible to repair the necessary tools in the field. The technique is fuel quality and at the same time very economical. As for the reliability, this model, like other machines, is not remarkable for perseverance. But it is very easy to service it, and all spare parts can be found on the aftermarket. The interior is heated, but the air conditioner has long been broken – as a result, I have to store by the windows before the heat, but it’s not bad, even taking into account the age of the model.
- Boris, Stavropol Territory. LTZ-155 is the best tractor we have in our farm. It efficiently copes with milling and crumbling of the soil, is adapted to tillage in different ways. It is used for sowing grain and vegetable crops, harvesting, cleaning, etc. In general, it should be admitted that the Lipetsk engineers did their best, having created the tractor ahead of its time. Despite the large number of breakages, only positive emotions remained from the machine. The front and rear hoods are not so increased in carrying capacity that they can be beaten with concrete weights. Fuel consumption is at an acceptable level. The cabin is well insulated from noise and vibration – at least in winter there is no construction.
Buying a used LTZ-155 tractor: selection features
Due to the fact that the tractor is not widespread, there are no offers on the market. And what there is, mostly with a lot of development. How to choose a used LTZ-155 and not to miscalculate?
When inspecting especially pay attention to the transmission, when working it should not give extraneous noises. Very often they sniff the hydraulics, and this is a reason to negotiate.
The engine in general of these tractors does not cause complaints, YMZ after all. But it is worth to drive it at work, give load and pay attention to the exhaust. Under heavy load any diesel smokes, but if the load is not critical, but the engine still smokes or regularly spits black, then there is a high probability that the fuel gauges will need adjustment or repair, it costs another reason to negotiate.
You can buy a LTZ-155 in the early 2000s for anywhere from 120,000 to 500,000 rubles. Anything below that price is spare parts.
CJSC Agrotehmash
Agrotehmash is a young production company that produces tractors at the production site in Tambov. Its history began in the 1990s, when “Agrotehmash” was a dealer of well-known European brands. In 2005, a sponsor was established in St. Petersburg, and the development of the first models and production of the first tractors under the “Kirovets” brand began. In 2008, the plant moved to Tambov on the territory of the former “Tambovmash” and created its own brand “Terronia”. At present, the plant produces four models with horsepower from 180 to 360 hp, the most powerful – Terrion 7380 ATM.

Terrion is considered the best Russian tractor. However, it has a disadvantage – the degree of localization is extremely low, all the main units are imported. Accordingly, the prices of tractors are high, repairs are not cheap and can take a long time in case of a severe breakdown. On average, about 400 tractors are now produced per year. Of course, this is not much, but the dynamics are strictly positive.
LTZ 155: Technical Specifications
This unique tractor was designed to perform the entire spectrum of agricultural work and many other areas of activity. Its design allows successful work in industry, forestry, road and construction.
In agriculture, the tractor is capable of performing the full cycle of work in cultivation of arable and grain crops. It can work with powerful wide-cutters, aggregate various units and work simultaneously with front and rear power arms. Great for tillage, plowing, transport and loader work.
Front and rear power arm, perforated shaft (front, rear, rear-upper and side), crawler, narrow twin wheels and attachments make the tractor truly versatile.

Modifications of LTZ-155 tractor
In addition to the basic model LTZ-155, the Lipetsk tractor plant produced a modification of the LTZ-155U. All their differences were that the rear wheels of tractor were not steerable. It increased turning radius up to 5600 mm and made tractor less maneuverable, but at the same time reduced the design.
