The T-30 tractor began its history in 1977, when it became clear that the successful predecessor model of the T-25 still required structural adjustments. Leaving the previous base, the designers of the Vladimir Tractor Plant installed a more powerful engine, which made it possible to make the front wheels also driving. The hydraulic system was slightly modified, and the unsuccessful heating system, which previously heated the outside air, was modified. Otherwise, this is still the same development from 1966 from Kharkov Tractor.
Appearance of the T-30 tractor
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).
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.

To do this, do the following: - unscrew nut 1 and remove lock washer 3. - use screw 2 to adjust the engagement of the roller with the worm until the play is completely eliminated. -install the lock washer 3 and tighten the nut. Eliminate the axial play in the bearings of the steering wheel axle by changing the number of shims 6, unscrewing the bolts 5.
Check the oil level in the steering mechanism and, if necessary, add oil through the hole closed with plug 4. The oil level is along the lower edge of the threaded hole.
14.10.3 Bleeding air from the power steering cylinder
When changing the oil in the HPS tank, after repair work (replacement
oil lines, cylinder, etc.), as well as in the case when, during straight-line movement of the tractor, the guide wheels begin to randomly “yaw”, violating the straightness of movement, perform operations to pump air from the power steering cylinder in the following sequence:
— fill the HEA tank with oil up to the top mark on the dipstick;
-start the diesel engine and set the crankshaft speed to the minimum stable speed;
— bleed the HPS system by turning the guide wheels from one
one extreme position to another, holding them at the extreme points for 5 - 8 seconds;
For the T30A-80 tractor and its modifications: — move the steering wheel to the extreme right (left) position; — remove the protective cap from the right (left) valve along the tractor
— put a hose on the valve head and lower it into a container with oil; — unscrew the valve 1.5-2 turns and release the air; — smoothly move the steering wheel to the right (left) side, continue
displace the air until oil comes out of the hose without air bubbles;
- close the valve; — remove the hose and put on the protective cap. Repeat the operations for the left (right) position of the hydraulic cylinder.

Cabin and controls
The driver's cabin of the T-30 tractor has a frame type construction. It has built-in equipment such as air conditioning and a fan. Thanks to this device, a high level of comfort is ensured in the cabin, regardless of the temperature conditions established outside and outside the cabin. The figure below shows the layout and functions of the devices of this vehicle.
To improve the cabin and viewing angle, it can be glazed on all sides. Such improvements will lead to better tractor control and more functional operation.
The control panel and steering wheel have a standard layout for tractors of this model.
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.
Gear box
The T-30 Vladimirets tractor has an eight-speed gearbox for moving forward and a four-speed gearbox for moving backward. Thanks to such a large gear shift range, the tractor can operate at speeds from 1.5 to 23.9 kilometers per hour. The arrangement of control parts in the T-30 tractor is presented below.
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.
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.
Consumer Reviews
TZ-30, a tractor that has received mostly positive feedback from users, has its drawbacks, which is typical of any technology. The owners cited the following points as advantages:
