Tractor T 30: characteristics, design, modifications

The T-30 compact wheeled tractor has been produced at the Vladimir tractor production plant since the mid-eighties.

The tractor, or as it was also called “Vladimirets”, is intended for mechanized work in agriculture.

The use of a variety of mounted, semi-mounted, and trailed equipment allows the T-30 to perform work for industry, construction, public utilities, forestry, and agricultural work.

The advantage of the agricultural unit is considered to be a good ratio of power and compact size. This makes it possible to operate in enclosed spaces, including on livestock farms, poultry farms and greenhouses.

Successful design and technical characteristics made it possible to create specialized modifications:

• 30 A 80 - all-wheel drive;
• T45 - option with a powerful 45 hp engine. With.;
• 30 KO - model for the housing and communal services sector;
• 30 SSH - self-propelled chassis;
• 30-69 - option for sowing and harvesting on land plots up to 20 hectares.

The popularity and demand for the T-30 model allowed the tractor to undergo a number of modifications, and the Vladimir Motor and Tractor Plant produces an analogue under the basic name Agromash-30TK.

Due to the reliability of maintainability and the large number of vehicles produced, the T-30s are still in operation. The Vladimir plant, in addition to tractors, produces special agricultural equipment and engines, including for the T 170 bulldozer.

Technical characteristics of the T-30 tractor

The Vladimirets T-30 tractor belongs to the category of universal wheeled vehicles with a traction class of 0.6 tons.

The machine is designed to perform work in the following categories:

• inter-row processing;
• soil preparation during the sowing campaign;
• cargo transportation;
• maintenance of livestock farms;
• communal sphere.

The dimensions of the mini tractor model T-30 are suitable for working in cramped conditions:

• length - 3180-3320 mm;
• width - 1560-1665 mm;
• height (with metal cabin) - 2605 mm;
• ground clearance (all-wheel drive version) - 345 mm.

The weight of a tractor filled and loaded with ballast ranges from 2022 (model 30-69) to 2500 kg (version 30A-80).

Wheeled tractor "Vladimirets" T-28

From 1958 to 1964, the Vladimir Tractor Plant produced the T-28 Tractor. This wheeled tractor, which received the nickname “Vladimirets”, was in great demand in the countryside, which, thanks to the dimensions of the agricultural machine, increased with the growing number of greenhouse farms. This is confirmed by the large number of copies produced - 80 thousand.

7. Fuel tank volume – 90 l.

Use of agricultural machinery

The technical characteristics of the T-28 “Vladimirets” tractor were used for the following agricultural work:

1. Mowing grass or other crops.
2. Processing of grown plants between rows.
3. Arable, sowing operations.
4. Transportation of agricultural products and other goods over short distances.
5. Maintenance of greenhouses, livestock complexes and farms.

The design and performance of the hydraulic equipment, transmission, and trailing mechanism of this agricultural machine made it possible to equip it with the following trailing devices: row-crop plows, harrows, seeders, plant feeders, milling cutters, modifications of cultivators.

If a small loader was required for piece cargo, the T-28 was equipped with a S11I-0.5 lifting boom and performed loading operations with a lifting capacity of up to 550 kg.

Advantages and disadvantages

Technical characteristics guarantee the T-28 tractor the following advantages:

• power and performance for this class;
• efficiency;
• versatility;
• light weight, which reduces pressure on the soil;
• simplicity of design;
• maintainability;
• long service life;
• permeability;
• operation in limited areas.

Possible disadvantages include undeveloped cab ergonomics, which leads to tractor driver fatigue. The rigid suspension design also led to discomfort. In winter, there was a problem starting the air diesel engine.

Variety of modifications

Cooperation between the Vladimir plant and the Tashkent Tractor Plant (TTZ) made it possible to create a modification called the T-28X tractor.

A design feature of this model was ground clearance. This made it possible to use the T28X for working in cotton fields.

In 1970, the manufacturer TTZ replaced the T 28X tractor with a new modification designated T28X2, which received a powerful power unit.

The interest that the T28 enjoyed in the countryside was ensured by the successful design of the T-28 tractor and its technical characteristics.

This combination made it possible to develop and produce a large number of modifications. The modification under the letter 28A had a front drive axle and a fixed track of guide wheels.

Although the agricultural machine and its numerous modifications have not been produced for a long time, representatives of this family can be found on the market.

They have a low cost, and the absence of complex units and components in the design compensates for the problem of finding spare parts. The unpretentiousness and ease of operation of the T 28 compensate for its shortcomings.

Engine

The T-30 is equipped with a 2-cylinder 4-stroke air-cooled diesel engine D-120. The engine is produced by the Vladimir Tractor Plant. It is possible to use several modifications of the engine, differing in the number of plungers in the fuel pump, the installation of a compressor for the pneumatic system, and the presence of oil drainage from the crankcase for heating the cabin. A design feature of a diesel engine is the placement of the combustion chamber in the piston. This ensures improved mixture formation and complete combustion of fuel.

The engine is equipped with removable cylinders of interchangeable design. The cylinders are cast from cast iron, with cooling fins located on the outer part. The inner surface of the cylinder forms a mirror. If the cylinders are worn or damaged, they cannot be repaired. The cylinder heads are individual, equipped with intake and exhaust valves, a fuel injection nozzle and a decompressor valve.

The camshaft is located in the engine crankcase. The shaft drive is carried out by a block of gears located in the front part. The gears are covered with a cover. The block contains guide bushings through which the pushers pass. As the camshaft rotates, the cams move the pushrods upward. The pushers are connected to rocker arms mounted on the head. The rocker opens the valve by acting on the end of the rod. The closing of the valves and the return of the pushers to the lower position is carried out due to the force of compressed springs installed in the valve mechanism.

Cooling is carried out by air flow generated by an axial fan. Belt drive from a pulley on the engine crankshaft. Air is supplied to the cavity of the casing mounted on the side of the cylinders. The air flow is directed by deflectors and flows around the fins. Under the casing there is a radiator for the engine lubrication system. The intensity of the air flow is adjusted by turning the disc valve located at the air intake inlet.

Tractor device

The T30 tractor is developed on the basis of the T-25 model. He took more than just individual parts of the structure from his predecessor. It also received reliability, build quality and the ability to work in different climatic conditions. Individual components and assemblies have been changed and improved. This increased the service life of the equipment.

The tractor is equipped with a new drive system to which all wheels are connected. Due to this, the tractor received better maneuverability. When wheels slip in marshy areas, an axle support is connected to the rear wheels. The endurance of the tractor is increased due to the installed clutch and shaft unit for power regulation.

The Vladimirets T-30 tractor accelerates to 24 kilometers per hour. It is equipped with a gearbox with eight forward and two reverse speeds.

The steering is worm-roller or hydrostatic.

The installed attachments are capable of lifting up to 600 kilograms of weight.

The cabin, mounted on a frame, is designed for only one person. Comfortable conditions are created through ventilation and heating systems. Good visibility through the large glass area is ensured by the windshield wiper system.

The T30 tractor is aggregated with various types of attachments. This expands the scope of its application.

Transmission

The transmission includes a clutch mechanism and a gearbox. The machines use a clutch with a dry operating principle. The clutch is equipped with 1 disc and is in a permanently closed state. When installing an additional shaft on the tractor to drive implements (PTO), a separate disk is added to the coupling to transmit torque to the shaft.

The manual gearbox and doubler in the rear axle reducer provide 6 normal forward speeds. The reversible gearbox allows you to use these gears for moving backwards. When working in off-road conditions, 2 additional gears are used, allowing you to move in slow motion. Slow speeds only apply to forward movement.

On vehicles of the T-30 family, 2 types of PTO are used - dependent and independent. Both options provide 1 operating speed - 540 rpm. Drive shafts differ in diameter and number of splines; there are 2 configuration options.

Price

Many farmers are interested in the question of what the price of the T-30 tractor is. Should I buy it new or used? This is difficult to judge. When choosing a technique, you need to accurately determine the purpose and the available amount. Two to three thousand dollars is the price for a used, but in excellent condition, T-30 tractor. A new one costs about ten thousand dollars or more. It also depends on the dealers and other parameters. If we talk about a set of used tractor and additional equipment, then its cost can increase to six to seven thousand dollars.

When buying a used T30 “Vladimirets” tractor, you must carefully check its technical condition. By comparing the condition of several options and their prices, it is easier to make the right choice.

Front and rear axle

The front axle is a beam mounted on a balancer. The T-30A-80 modification is equipped with a front drive axle with an automatic connection system when the wheels on the rear axle slip. The drive is carried out by a cardan shaft from a gearbox located on the gearbox.

The rear axle gearbox is equipped with a differential with the possibility of mechanical locking by a pedal. The axle shafts are located in the side sleeves, on which the final drive reduction gearboxes are mounted. Rear axle gearboxes allow you to change the vehicle's ground clearance.

Peculiarities

1. The tractor has compact dimensions. Thanks to its length of 3.8 meters and a wheelbase of less than 1.8 meters, the vehicle has good maneuverability and dynamic parameters. Due to its compact size and low weight, it was possible to reduce the turning radius and increase ease of use in cramped conditions. To ensure decent geometric cross-country ability, the T-30 Vladimirets tractor received wide-profile drive wheels, 350 mm ground clearance, and a rear differential lock. The first modifications were equipped with front-wheel drive, and later versions received an all-wheel drive layout. This significantly increased off-road capabilities, especially coupled with the center differential lock. In addition, among other features of the body and chassis, we note strong protection of the underbody and engine compartment, as well as minimal body overhangs and high approach and departure angles. Many years of practice have shown that the machine is capable of overcoming steep 30 percent inclines, deep holes and ruts, as well as moving on loose and muddy soil.
2. The vehicle received a universal three-point hitch with a total load capacity of 600 kg. The hitch is driven by a hydraulic system, which has its own hydraulic pump with optimal flow capacity. In addition, the developers have provided the ability to adjust the track of the front and rear axles in the range of 1200-1400 mm, depending on the complexity of the work being performed - for example, in the process of processing inter-row plantings.
3. As a power plant, the T-30 model received a two-cylinder diesel unit D-120. Its power reaches 30 horsepower, which is enough for most agricultural and utility work. Let us highlight the main features of the power plant:

• Low fuel consumption and good environmental performance. So, the motor consumes an average of 180 g/l. With. at one o'clock. A spacious 290-liter fuel tank provides a long range, allowing you to travel long distances and handle heavy loads without worrying about unscheduled refueling
• The motor has excellent traction characteristics. Torque is transmitted to the gearbox via a double-disc clutch with a permanently closed design.

Transmission

The T-30 Vladimirets tractor received a multi-stage transmission with 8 forward gears, which operate clearly and almost silently. The box allows you to fully unleash the potential of the power plant, and contributes to a maximum speed of 24 km/h. There are four gears for reversing. Using reverse gear increases maneuverability and ease of operation in hard-to-reach and cramped conditions. In addition, thanks to the reverse gears, it is much easier to perform a 180 or 360 degree turn. Another important component of the transmission is the power take-off, which operates in two modes - independent and synchronous. The PTO (power take-off shaft) can be switched between preset speeds - 500 and 1000 rpm.

Cabin

The single-seat cabin of the T-30 Vladimirets tractor is quite comfortable and has an optimal range of various adjustments. Thus, metal sheets connected to each other by spot welding were used to build the cabin. This design ensured the rigidity of the body and made it possible to abandon the installation of a tubular frame, because the cabin already protects the operator well in the event of a rollover. Despite the single-seat cabin, the cabin is very spacious - largely thanks to the high ceiling and strictly vertical landing. The driver's seat and steering column can be adjusted at your discretion - this allows you to choose the optimal position for your height and build. The presence of panoramic glazing significantly increases visibility to the sides, and thanks to the built-in heating and ventilation, the cabin is comfortable and cozy, in any weather. Due to this, the machine is well adapted not only for summer, but also for low-temperature conditions. A front windshield wiper is also included as standard. All controls are located at hand, and you don’t have to reach for them. For example, the gas and brake levers are located in the traditional place - under the steering column. On the front panel, in addition to switches and rear implement controls, there are gauges showing current oil pressure and temperature.

Repair and operation of the T-30 tractor

Ease of use and good maintainability made the tractor very popular in the post-Soviet space. The T-30 model received a decent price-performance ratio. The relatively low-power engine made it possible to reduce fuel consumption and reduce harmful emissions, but the low power did not negatively affect the excellent traction characteristics of the engine. This allows you to use the machine's capabilities with 100% efficiency. A developed service base, as well as the possibility of repairs in the field, all this makes it easier to operate the tractor for many years. All components for this machine today can be found on the secondary market. In addition, many parts are unified with other domestic tractors.

Chassis system

Tractors use wheels with different diameters on the front and rear axles. The machines are equipped with a track adjustment system on the front and rear axles. The front axle has 3 stages of adjustment every 100 mm. The track of the bridge equipped with a drive is 100 mm larger than the track of the standard unit.

The rear wheels allow you to adjust the track in 4 steps.

Disc-type brakes are installed on the rear axle. Separate control is carried out by 2 pedals from the operator's cabin. The parking brake uses operating mechanisms. Model 30-69 vehicles use a mechanical steering gear. Versions 30-70 and 30A-80 received hydrostatic control with a power cylinder mounted on the front axle.

Tractor Vladimirets T 25

The model was produced at the Vladimir Tractor Plant from 1972 to 2000. The T 25 has a semi-frame design with a front-mounted power unit and rear-wheel drive.

Tractors from the Vladimir plant T 25 were equipped with a two-cylinder power plant. Maximum engine power is 25 horsepower. The motor is mounted on elastic cushions, which helps smooth out vibrations transmitted to the cabin during operation.

The power unit is started from a 12-volt electric starter. The starter's power source is a rechargeable battery. The starter is included in the electrical wiring according to a single-wire circuit. The negative contact is the starter housing.

Dimensions T 25:

1. Tractor length – 3.11 meters;
2. The width on the outer sides of the wings is 1.37 m;
3. Cabin roof height – 2.5 m;
4. Track – adjustable;
5. Longitudinal base – 1775 mm;
6. Ground clearance under the rear axle – 435 mm;
7. The weight of the car - depending on the modification - is from 1780 to 1820 kilograms.

The tractor cabin is equipped with a heater, this allows the machine to be used at low ambient temperatures. For safe driving on public roads, the T 25 has light and sound alarms.

From the above it follows that Vladimir tractors, the model range of which is given above, are multifunctional machines. Universal attachments and high technical characteristics allow them to be used in various fields of activity.

Main modifications

All models based on the T-30 are equipped with the same power plant and gearbox. Some components and assemblies were subject to changes.

The VTZ plant produced several versions of the machine:

1. The T-30-69 tractor, which is distinguished by the installation of a dependent PTO and an additional drive disk in the clutch. The machine was positioned as an agricultural one, for performing auxiliary work.
2. The T-30-70 model is equipped with a reinforced clutch with 2 discs and an additional clutch for driving an independent PTO. The vehicle was created to work on vineyards and transport goods.
3. A variant of the T-30A-80 tractor, which is equipped with a transfer gearbox and a driving front axle. Hydraulics with increased performance.
4. Model T-45 with a 3-cylinder diesel engine D-130 with a power of 45 hp. It was not produced for long, but thanks to its powerful engine it had improved performance characteristics.
5. The utility version of the T-30KO was equipped from the factory with equipment for street cleaning. The modifications listed above served as the basis.

Analogue machines

Of those produced at that time, it is worth mentioning the T-25 of the Lipetsk Tractor Plant. In terms of technical characteristics, it is very similar to the T 30, on its basis it was created. The difference from this car is all-wheel drive, the T-25 did not have all-wheel drive.

The HTZ T-30 tractor is produced at the Kharkov Tractor Plant. There is little information about the current state of production, but in the 1990s it came off the production line. The difference from its Vladimir counterpart is in the controls and clutch, and in the power take-off for attachments.

MTZ-82 is the most common analogue. It is produced in various modifications in Minsk to this day. It has slightly worse visibility, larger dimensions and power.

When working on agricultural land, the ability to use agricultural equipment is superior to the T-30, but in terms of maneuverability, visibility from the cab and, as a result, suitability for use in public urban services, it is significantly inferior to it. The fuel consumption of the MTZ-82 is also significantly higher.

Utility loaders. They are produced at various factories, mainly in Moscow and the Urals. Positioned as universal machines for street cleaning, small construction and earthworks. Almost anywhere they are used, the T-30 can also handle it just fine. All utility loaders are inferior to the T-30 in terms of visibility from the cab and versatility. Loaders with rear hydraulics have almost no rearward visibility at all.

Advantages and disadvantages

The characteristics of the T-30 tractor provide a number of advantages:

• ground clearance allowing for work in the field;
• closed cabin with large glass area;
• adjustment of track and ground clearance;
• low fuel consumption;
• ease of repair and maintenance;
• ability to work with various attachments.

Reviews of equipment allow us to highlight a number of disadvantages of the machine:

• low location of the front axle drive shaft;
• the need to adjust the clearance in the clutch;
• low comfort of the operator's cabin.

5. Increased oil consumption (piston ring wear)	Replacing rings
6. The brakes do not work well (the brake band linings are oily, the brakes are not adjusted)	Adjusting the brakes. Replacing or washing brake linings.

Price and owner reviews

The cost of used cars starts from 100 thousand rubles. For this price, tractors are offered with standard equipment without attachments. The remaining life of the machines is small; most require major repairs of the engine and transmission. More recent copies cost from 200 thousand rubles. Additional equipment brings the cost to 400 thousand rubles and above.

The cost of the VTZ-2032 tractor in the version with rear drive wheels is 495 thousand rubles, with all-wheel drive - from 60 thousand rubles.

Artem, Tver region.

There are 3 vehicles in operation, modification 30A-80, produced in the mid-2000s. and 1 model - late 90s. On late-release tractors, there are problems with the axle gearbox associated with breakage of shafts and gears. After replacement, the parts do not last long. There are no such problems on an early car. The transfer case and driveshaft are installed low, which causes damage to the unit. There is a high probability of impacts on the crankcase when driving in deep ruts. The engine for all-wheel drive has low power, on the other hand, the chassis cannot cope with more power.

Dmitry, Sochi.

The tractor is used for forestry. Equipped with cabin and glass protection. Protective screens for the front axle drive and oil pump are installed from the factory. The kit included a skidding blade on the front linkage and a forestry plow. The blade was used for lifting purposes; the hydraulic power was enough to move large tree trunks. The vehicle's cross-country ability is at the level of GAZ-66 trucks with all-wheel drive. The cooling system is reliable, it is almost impossible to overheat the engine.

Power units

“Vladimirets” is equipped with a D-120 diesel engine, which has a power of 30 horsepower. Its power is twice as great as its gasoline counterparts. This is achieved by increasing the compression ratio.

The volume of the fuel tank is 290 liters. Fuel consumption 180 g/l*hour.

A motor with two cylinders arranged vertically in a row. The crankshaft rotates at a speed of two thousand revolutions per minute. Engine cooling is air.

Only high-quality materials were used to manufacture the engine. This increases service life and delays repairs. The tractor has increased productivity.

Control

The technical characteristics of the T-30 universal row-crop tractor determine that it has a traditional steering system. In addition to the steering wheel, you can control the movement of the machine using foot pedals and hand levers. The instrument panel is equipped with a large set of warning lights, as well as fuel sensors.

Reduced front wheels significantly increase the maneuverability of the tractor. Unauthorized sliding when driving on slopes is eliminated due to a special tread on the rear tires.

Older models used a dependent-type power take-off shaft, as well as a single-plate clutch. Now factories install a double-disc clutch, and the PTO has become independent.

Reviews

• Alexander, Minsk. T-30 is a successful tractor of its time. The machine is still in demand in agriculture. This tractor does an excellent job of hilling soil, cultivating and harrowing. Despite the frail engine, its power and torque are sufficient to tow 600-kilogram trailers, cultivate hard soil, and, if necessary, weights can be installed for better stability and weight of the tractor. The car is equipped with a heater and ventilation, which, however, have already been repaired several times. Fuel consumption is at an acceptable level. In addition, the car is undemanding in terms of fuel quality, so you can fill the engine with any diesel fuel. As for noise and vibrations, after 20 years of work I have already come to terms with such shortcomings. Of course, you can modify the interior and make it quieter, but the design will not change, and over time, cracks, vibrations and extraneous sounds will appear again. All this is due to the loud rattling diesel engine, which makes noise like a steam locomotive. But Soviet people got used to something different than I did.
• Anton, Moscow. Overall, I liked the machine, but Soviet engineers decided to save on everything, since the tractor was already a budget one. There is no sound insulation in the cabin, which is why vibrations are present in the steering column and seats. There is no desire to modify the cabin - install a new seat, insulate it or soundproof it. I need the tractor purely for work. The tractor copes with soil cultivation confidently, if you have the necessary attachments. The equipment is capable of replacing a plow, hiller and cultivator, and is also capable of towing 600-kilogram trailers. I liked the good visibility due to the wide glass area. I will also note the tenacious rear wheels, which provide ideal traction on loose soil. Repairing the T-30 tractor is not difficult. All elements of the engine compartment are located well, and you don’t have to reach for them to get them. With timely care, the tractor will bring more benefits than problems. It is very cheap to maintain, especially compared to foreign cars.

What do you need to know about it

The tractor is a universal row-crop type machine. People call him by the sonorous name “Vladimirets”. Mainly exploited in the agricultural sector. With it you can:

• cultivate the soil;
• engage in sowing work;
• care for crops;
• carry out inter-row processing.

The T-30 modification tractor has found its widespread use in gardening, municipal and farming organizations, as well as in the business industry. It can be used to transport relatively small loads. Class – 0.6.

The T-30 “Vladimirets” tractor is manufactured by the Vladimir Motor and Tractor Plant. This is one of the oldest models - the first cars rolled off the assembly line back in the sixties of the last century. Its predecessor is the no less famous T-25. This modification is also produced at the Lipetsk Tractor Plant. Therefore, there are models on the market labeled VTZ or LTZ, which depends on the manufacturer.

T-30 is a tractor whose quality has been tested by time. Functionality, simple operation, ease of maintenance, efficiency, good assembly - these are all the factors that directly affect the demand for a machine, which has been relevant for more than half a century.
