Czechoslovak mini tractor tz-4k-14

The TZ-4K-14 minitractor is a compact agricultural machine developed by a Czech manufacturer. This model uses many elements from its predecessor (TZ-4K-10), but differs from it in many technical improvements and improvements. It is worth noting that the Czech minitractor is one of the first purchased by the Soviet Union in the 1970s. The technique was actively used in the construction of various facilities for the 1980 Olympics in Moscow. In practice, the car performed quite well, which ensured its great popularity in the territories of the USSR. Also in connection with this, the TZ-4K-14 was taken for the development of Soviet mini-tractors and in the late 1980s it introduced its version of the MA-6210 mini-tractor, which was produced in limited quantities.

The machine has a rotating fork through which the front and rear axles are connected. When turning, the mini-tractor axles rotate 45 degrees relative to each other. This solution made it possible to achieve excellent maneuverability, which made it possible to use the machine in rather cramped conditions, since the smallest turning radius is only 1900 millimeters. In order to ensure improved cross-country ability, the fork design provides for raising and lowering the axles by 11 degrees. The front and rear track widths can also be adjusted for this purpose. Initially, this figure is 700 millimeters, but can be expanded to 1000 millimeters.

The mini tractor uses a single-cylinder, two-stroke, air-cooled diesel power plant. The engine can operate in any conditions without overheating, since the air cooling system copes with its task perfectly, since the overall dimensions of the engine are quite small. The unit is started using an electric starter, but can also be started manually. The gearbox used has four reverse gears, both for forward and reverse movement. Each axle has a differential. The front axle differential has locking functions, since this axle is the driving axle in the model. The manufacturer added two independent braking systems to the mini-tractor, including a manual front brake and a foot-operated rear brake.

Carrying out tractor maintenance

The Czech mini tractor TZ-4K-14 is easy to operate and easy to maintain. The most necessary actions are:

Carrying out regular cleaning of dust and dirt not only from the body, but also from large components.
Carry out regular monitoring of tire pressure, especially before using attachments.
Every 70 operating hours, check the operation of the clutch and brake system.

Preservation of a tractor for a long period is carried out according to the following rules:

Clean and dry the entire mini tractor;
Drain lubricant from all systems;
Lubricate all parts and mechanisms with a rag soaked in oil;
Place in a dry, ventilated area and cover with a tarpaulin or cover.

wheel track - 70-100 cm.

The mini tractor can be equipped with attachments. The most commonly used are dump trailers, plows, and mowers. To carry out work on leveling the soil or clearing snow, you can install a bulldozer blade.

Engine

Over the years of tractor production, the engine has been modified several times. The first model TZ-4K-14 was produced with a Slavia 1D80 engine, its power was 9 hp. With. Since the Czechs used only locally produced spare parts, there were no problems with replacing structural components. High-pressure pumps are also produced in the Czech Republic by Motorpal JSC.

By the time of delivery to the Soviet Union, the tractor was already equipped with a single-cylinder two-stroke diesel engine 1D90TA. Its power was increased to 12 hp. With. Working volume - 660 cm³. The engine has an air cooling system and can be started either by an electric starter or manually.

The simplest possible design determines the maintainability of the engine and minimizes the amount of maintenance.

Power transmission

The dry single-plate clutch is activated by a pedal, which is located on the driver's platform on the left. The tractor has a 4-speed gearbox. All gears are reversed. There are wheel drive switches in the front and rear gearboxes.

Using the articulated and through shafts, torque from the drive shaft is transmitted to the front and rear gearboxes. To turn on the drive shaft speed, there is a manual lever; it is also equipped with a safety lock against accidental starting of the engine.

Chassis

The TZ-4K-14 all-wheel drive mini tractor chassis. The front axle differential lock is created from a gear coupling. This helps prevent the drive wheels from slipping on slippery ground. The mini tractor has no restrictions on driving on general roads due to the low specific pressure of the pneumatic tires on the ground and the effectiveness of the internal shoe brakes.

The machine has high technical performance and is unpretentious to operating conditions. The model is used in various fields with a wide range of additional equipment.

Purpose

During the Soviet Union, the TZ-4K-14 minitractor was used almost everywhere, in every field of activity. The equipment was very popular in construction, public utilities and agriculture. In construction, the tractor mainly carried out transportation of any cargo and materials, as well as leveling embankments. In rural farms, machinery was actively used for all types of work, as this made it possible to produce a very wide range of additional attachments. In public utilities, a mini-tractor was used mainly for clearing snow from some areas, but transportation of various loads should not be excluded.

Currently, this technique is also used, but for the most part only in greenhouses, vegetable gardens, farms and small rural farms. The great demand for the model is due not only to a wide selection of additional mounted and trailed units, but also to excellent performance indicators, the key of which are maneuverability and cross-country ability. The vehicle is capable of towing trailers weighing up to 1,500 kilograms. But the TZ-4K-14 mini-tractor turned out to be not very convenient when working with plows, since the articulated frame brings a lot of inconvenience when plowing the soil.

The TZ 4K 14 tractor has a wide range of mounted implements

The Czech mini tractor can be combined with various types of mounted implements, including a dump trailer, a harrow mower, a plow, a brush, and a blade. A single-axle metal trailer is used to transport various loads weighing up to 1,000 kg. The trailer is equipped with a removable rear wall and can be tilted backwards, making it much easier to unload. The trailer has overall dimensions (l x w x h) 2,630 x 1,700 x 980 mm. The mower attached to the TZ 4K 14 is the best option in cases where it is not possible to use a conventional tractor with a side mower, for example on small plots, in parks or gardens.

A bulldozer blade is used to clear areas of snow or level the soil. The big advantage is the ability to quickly install/dismantle the blade on a mini tractor and easy control of the unit. The blade width is 1,000 mm and the rotation angle is 45°. A sweeper is used to clean sections of the road or other places from dust. The drive mechanism is protected against dust.

Another tool that can be mounted with a mini tractor is a mounted milling cutter. Its main purpose is the processing of dry clay and clay-silt plowing, mixing the soil with compost or manure, as well as loosening the soil in wide-row crops and removing weeds. The reversible plow is used for smooth plowing; its working width is 250 mm. The plow has a design that allows the layer of earth to be laid in one direction. It is recommended to use it on small, irregularly shaped areas. The plowing depth reaches 21 cm. The row spacing of fruit nurseries is processed using a ripper. The maximum loosening depth of the unit is 6-8 cm, and the working width is 85 cm.

The versatile, convenient and durable Czech-made mini tractor TZ 4K 14 is indispensable in cases where more powerful equipment cannot be used. Possessing a significant margin of safety and having a simple operating principle, the tractor will please its owner, because frequent breakdowns during operation are excluded. The price of TZ 4k14 is about 175,000 rubles, however, there are not many advertisements for the sale of these tractors.

Description of the Czech tractor TZ-4K-14

The Czech tractor TZ-4K-14 is an all-wheel drive vehicle with a wheelbase on two axles. A foot mechanism is used as a brake for the rear axle, while braking for the front axle is carried out using a handle. The prototype for the development of the TZ-4K-14 was its predecessor, the TZ-4K-10, which had less power and was produced with various Slavia 1D80 fahr engines with an operating power of 9 hp. and 1D 90 TA with a power of 12 hp.

Mini tractor TZ-4K-14

A special feature of the Czech mini-tractor TZ-4K-14 is its minimum turning radius, which is 1.9 m. It is very easy to move on uneven terrain, because the design of the tractor is thought out in such a way that it allows you to follow the terrain, and the ground clearance is 37 cm. The weight of the unit is 870 kg, and the dimensions are 2.75 x 0.95 x 1.3 m. This compact unit can be used in narrow row spacing, as the track is adjustable from 70 cm to 1 m.

Owner reviews

Igor:

“The Czech TZ tractor worked for my father from 1997 to the present day. About 10 years ago I put it in for a major overhaul, changed the gearbox, and something else. Now I am cultivating a plot of 25 acres on it. Very reliable, well thought out design."

Alexander, Novgorod:

“I bought the TZ tractor by accident, used, I’ve had it for 15 years. During this time, I rebuilt the crankshaft and changed the tires on the front wheels. I compare them with Chinese mini tractors of the same years of production as my TK, but there is no comparison. Although you can’t find original spare parts for it now, everything can be repaired. And my friends’ “Chinese” ones are never out of repairs. Good technology was invented once.”

Service

Czechoslovakian mini-tractors are quite unpretentious and do not require expensive maintenance

However, given that the average age of models exceeds 20 years, special attention should be paid to regular maintenance, which is recommended every 200 hours of operation. So, it is necessary to inspect the equipment weekly and remove carbon deposits from the exhaust pipe.

You also need to monitor the condition of the fuel filter and, if necessary, replace it on time. In addition, it is necessary to regularly change the oil in the transmission system and tighten the cylinder head bolts.

When using equipment intensively, it is necessary to monitor the condition of the tire tread and swap them for more even wear. Strict adherence to maintenance recommendations and operating instructions will ensure trouble-free operation of the mini-tractor and will also significantly extend its service life.

In the next video you will find recommendations for setting up the lubrication pump of the TZ-4K 14 mini-tractor.

A little history

The production of Czechoslovak mini-tractors exported to the USSR was carried out by the Agrostroj plant, whose production facilities were located in Prostejov. The company's earliest model was the TZ-4K 10 modification, which had an extended base, a 2 m long body and a Slavia 1D-80 engine with a power of 9 hp. With. Then they began to install on the tractors a 12-horsepower diesel engine with an air cooling system of the 1D-90TA brand, capable of starting either using an electric starter or manually.

The chassis and chassis also underwent some changes over time, as a result of which the base was shortened, the body was modified, and a hydraulic trailer appeared. The model was called TZ-4K 14. It was manufactured until the end of production.

For the first time, Czech technology appeared in the USSR on the eve of the Moscow Olympics. Then it was used to work at sports facilities. The units were liked by Soviet specialists and began to be actively purchased by agricultural enterprises and public utilities.

The production of mini-tractors ceased in the mid-90s of the last century, however, thanks to the highest quality and very successful design, a large number of long-lived units are still operating in the countries of the post-Soviet space.

The TZ-4K 14 model was taken as the basis for the development of the domestic version, and in the late 80s the first prototypes called MA-6210 rolled off the Tallex assembly line. However, the equipment was produced in very limited quantities, and after certain events its production was completely discontinued.
