Techniques from the past of the LTZ 55 tractor. Overview of the model, video of work, properties and reviews
LTZ 55 has been produced at the tractor plant in Lipetsk since 1991, which was built in 1943 in the midst of the Second World War. The company’s first product was the Kirovets 35, which quickly became widespread in agriculture.
In 1956, the T-25 tractor was released, which was upgraded a few years later, and in 1960, the legendary T-40, which was recognized as one of the most reliable domestic machines. At that time, it was the most advanced technology, which only began to be used in the late 1990s. At that time, it was replaced by the LTZ-55.
At first, the equipment was designed for agriculture. However, various attachments allow to use them for cargo transportation, construction works and services in the field of housing and communal services.
Technical characteristics
LTZ 55 was one of the advanced tractors in Russia. Its main characteristics are:
- Dimensions: 3750 x 1710 x 2560;
- Depending on the grade, the reach was from 500 to 600 mm;
- Weight without attachments: 2.65 tons;
- Basic length: 2145 mm;
- Length: 1,375 to 1,840 mm.
engine
The D-144 four-stroke diesel engine moved to the T-40. At the same time, it has been modernized, and the engineers managed to increase the power up to 50 liters. ะก. With a capacity of 4.15 liters. Diameter of each of the four cylinders is 105 mm. Operating speed is 1800 rpm. With this engine the tractor can accelerate up to 30 km/h.
Fuel consumption
Despite the power, fuel consumption is reduced and is 242 g per kWh. At the same time, it meets all environmental requirements and emits a small amount of pollutants into the atmosphere.
In the 1990s, emissions were also up to European standards with their terrific attitude to the environment.
Transmission, clutch and steering
The tractor features a dry clutch transmission. There is a reverse for each of the eight speeds. Dry-strip brakes provide excellent braking. The handbrake is used for parking.
A hydraulically wrapped steering column controls the front axle. Thanks to a special mechanism, the steering wheel can be easily adjusted in height and angle.
chassis
The LTZ-55 is powered by rear-wheel drive. Thanks to the rigid rear suspension it can withstand heavy loads. The front axle is fitted with a feather block to increase ride smoothness.
The rotating load from the box is transmitted by a pair of bevel gears. The differential is transmitted to the front axle by a ratchet on top.
Noise isolation
Compared to previous models, the noise level in the LTZ-55 cab is much lower. Although it’s too early to talk about complete noise isolation, a significant breakthrough has been made in this direction.

Also installed more comfortable armchair. In general, it is pleasant and comfortable to work in such a cabin.
The heater works well, and even in the most severe frosts it is possible to work specifically. Thanks to such equipment, it is possible to carry out the necessary work in climatic conditions.
It is worth noting that there were also export upgrades of the convertible type. They were produced for warm countries without the dachshund.
Attachments
With the installation of various attachments, the tractor’s functionality expands considerably. First, the model was designed for three types of such devices:
- Semi-modified units that perform various operations independently of each other;
- Attached devices, which are combined with the working mechanisms. Can perform a variety of functions;
- Devices that interact with different parts of the tractor.
There are more than 120 types of different attachments, with which you can use such devices in all sectors of the economy.
Owners reviews
Sergey Petrovich, Vologda: “The LTZ-55 tractor has been my reliable helper for 20 years. At the end of the nineties I bought it by accident, almost decommissioned. I restored what was possible, brought new units, had to remove a lot of rust. Now it doesn’t let me down, not to compare it to some of today’s tractors that my neighbors had on their first trip out to the field. No plastic bearings, tiny cracks or other miscommunications. “Anatoly: “When the farm expanded, the question arose of buying a big tractor instead of the small T-012. I bought a used LTZ 55 in good condition, the engine after overhaul. Working decently for 8 years, not going to change. “
Modifications
In addition to the basic model of such a tractor, the production of various modifications was found, which determined their use in various areas of activity. The main modifications were:
- LTZ-55A — thanks to the full configuration increased cross-country capability;
- LTZ-55N — well suited for mountainous areas. Reduced output makes the model more stable on slopes;
- LTZ-55an – a combination of the first two options.
- LTZ-55AL is a lighter version with reduced soil pressure.
Export-convertible varieties were used for sales to Central Asian countries and many southern countries that were allies of the USSR.
operation
In general, the LTZ-55 tractor received good reviews from users. They liked the compact and lightweight model, which has high productivity and wide functionality. In addition, it has a high level of cross-country ability and maneuverability, which allows them to work in the most hard-to-reach places.
The possibility of installing attachments allows you to perform various works that require high accuracy and minimum load on the ground, which is often important for work in the field.
Thanks to the unpretentious engine, it is possible to work in any climatic conditions, even under extreme temperature conditions. One of the most important advantages is efficiency, which allows you to perform an impressive amount of work at minimal cost.
Even an inexperienced operator can cope with the operation of this model. In addition, the LTZ-55 is perfectly repairable right on the spot and spare parts are easy to find. Regular maintenance can also be performed without outsourcing.
Attachments
The machine was originally designed for easy aggregation with three types of additional tools:
- Semi-mounted attachments that perform certain functions independently of each other.
- Attachable units, which are driven by coupling with work tools.
- Concerns that perform certain tasks together with various assemblies and mechanisms of the LTZ tractor.
Universal row crop tractor LTZ-55 is able to perform numerous works on tillage together with different devices (more than 120 names): plowing, cultivation, weeding, seeding, inter-row cultivation.
LTZ-55 has found application in household works – garbage and snow removal, forestry, loading and unloading works and in transportation of various cargoes up to 1,5 tons.
Main violations
The main problem area of such a tractor are the clutch bolts, which are easily damaged when handling them. This problem arises from the fact that the clutch was created on top of the predecessor without upgrading, and the engine was installed with increased power. The poor quality of the metal from which the latest tractors were made also affects. It should be noted that the problem of low-quality alloys is found in all modern household products.
Fuel and lubricant fouling often occurs. This occurs because of the poor quality of oil seals and other things.
The problem with the tractor is relatively low tractive force, and with a heavily loaded suspension, it is often difficult to start.
Consider the main irregularities and their causes
- Lack of oil or fuel;
- Dirt in the air or fuel filter;
- Problem with spark plugs or carburetor settings.
- Pedal adjustment required
- Disc or plating.
advantages and disadvantages
Over a long period of operation, experts have developed a certain opinion about such a machine. Therefore, it is now easy to highlight all the advantages and disadvantages. The advantages of the LTZ-55 include:
- Versatility. It is possible to install any agricultural devices and other attachments, which significantly expands the functionality.
- High cross-country capability. Compact size, powerful propulsion system and excellent handling allowed to use the opportunities to work in the most difficult places.
- modest. The tractor is equipped with an air engine cooling system, so it is not afraid of the strongest frosts, during which the liquid in the radiator freezes.
- repairs. It is possible to eliminate various malfunctions in the field.
Among the disadvantages are usually highlighted:
- The level of noise reduction is much lower than that of foreign analogues. Also there is no automatic ventilation system, so in the warm period you have to work with the door open and the hatch on the roof.
- Light weight is an advantage of the model, but when transporting heavy loads slippage is possible.
- As mentioned above, the tractor suffers from frequent oil and fuel leaks. However, this is a problem of all Soviet devices, which has not been solved in our time.
Despite its shortcomings, this tractor is actively used even many years after it was removed from production. It still successfully copes with its tasks and at the same time is easy to maintain and inexpensive.
Features of operation and repair
For grinding and mechanisms, the tractor works at partial speed. During this period, it is recommended to perform all work and avoid excessive loads.
After completion of the mileage it is necessary to change the oil in the engine and transmission.
Every 50-100 hours of work it is necessary to periodically clean the tractor body from dust and oil stains, control tire pressure, adjust clutch and brake pedals.
At the end of field work is carried out conservation, namely: tractor is cleaned from environmental pollution, dried, drained of water and fuel, lubricate the parts to prevent corrosion, cover and put in a dry place.
LTZ-55
LTZ-55 tractor had all reasons to take the most worthy place in the line of universal machinery of this class.
Qualitative, down to the smallest details, simple design, use of unified parts, increased functionality, economical fuel consumption (lower than the famous MTZ-80), easy access to major components – all these criteria were created on the LTZ-55. Once recognized leader.
LTZ-55 tractor is not demanding to the quality of fuel and lubricants. Maintenance, fuel consumption and oil changes are carried out as usual.
The technique is characterized by high repairability, the presence of shortcomings and malfunctions. The owners note a very high traction, because of which the vehicle with a loaded trailer sometimes doesn’t move immediately. Fuel and oil leaks occur.
The weak point is the clutch level inherited from the T-40, which can be not designed for the powerful LTZ-55 engine. Although many owners find that replacing the lugs with the original ones from the T-40 eliminates the problem, which speaks to the poor quality materials and alloys in today’s products.
In the early 2000s, the Lipetsk Tractor Plant existed for several reasons.
Due to the high level of service, LTZ tractors are still of interest to machinery owners.
High quality, optimal performance properties at a low price. This is really a big advantage of the LTZ-55.
Price
This model could have become a leader of tractor building in our time, if it were not for the collapse of the plant in the 2000s. In addition to good technical characteristics, this model had a fairly low cost.
During its existence, the plant did not have time to produce many similar models, and therefore it is not easy to find the LTZ-55 in the secondary market. Now it can be found only on billboards and bought in the range of 50-300 thousand rubles, which is considered a very low figure.
The use of such tractors nowadays indicates a high demand for machinery of this class. In modern agricultural companies the demand for inexpensive, compact and powerful machines is constantly growing.
The structure of LTZ-55
The design of the device is simple and reliable, which makes it the best solution for intensive operation in difficult conditions. Repair and maintenance of LTZ-55 with the necessary experience and skills does not require much effort, as most manipulations can be performed by yourself.
To make sure of the low cost of maintenance, it is enough to study the spare parts catalog for the availability of the required node. Spare parts for this model are widespread in the USSR and make it easy to find the necessary components. Considering the construction of the tractor, it is advisable to mention the following nodes:
- engine;
- transmission, clutch, steering;
- The chassis;
- Cabin.
The Tractor Cabin
Each of these nodes has many features, which should be considered in more detail. The engine for the tractor is made by the Vladimir Motor Plant, the volume is 4.15 liters, relatively low fuel consumption. The product is equipped with 4 cylinders and belongs to the diesel type, which makes it even more economical.

The transmission used in the design is of the mechanical type and has 8 gears with reverse for each gear. Unlike older models of tractor equipment, the LTZ is equipped with hydraulic linkage steering, which greatly improves its handling.
The cab of the machine meets the requirements of the time and provides a minimum level of comfort to the driver-operator. In addition, it is characterized by increased tightness, which is especially important in the cold season. The quality of sealing materials is far from ideal, which is manifested by poor soundproofing, workplace, as well as increased vibration.
The cabin is characterized by an impressive viewing angle, which makes it easier to maneuver in the absence of free space, typical, for example, for construction sites.
