Overview of the TZK-4 mini tractor with a two-body plow

The TZ-4K-14 is a Czech mini tractor that was discontinued in the mid-90s. last century. But the model turned out to be so successful that even now you can find the Czechoslovakian "long-liver" TZ4K14 in private farms and small agricultural enterprises on the territory of the former USSR.

The history of the appearance of the tractor in our country is associated with the Olympics-80. In those years, everything was produced in Czechoslovakia in small volumes and one could not worry about the quality of the products. To facilitate the work on the Olympic facilities, a compact wheeled tractor equipment was purchased from the Agrostroj plant in Prosteyev.

Today, the range of application of the mini tractor has become even wider. The assortment of attachments allows the use of such equipment not only in agriculture, but also in the utilities (snow and debris removal), in the construction industry (laying of communications, transportation of goods).

Advantages and disadvantages

The enduring interest of Russian consumers in technology from the Czech Republic is due to a number of its important advantages.

• Excellent maintainability and high reliability. Despite the fact that the “youngest” model of Czech production is already more than 20 years old, the units are quite efficient and highly appreciated by farmers and public utilities.
• The small turning radius allows for soil cultivation in large greenhouses and greenhouses, as well as in small summer cottages, without the risk of damaging neighboring plants.
• Excellent traction and coupling characteristics make it possible to tow tractor trailers in conditions of clay soils and off-road conditions.
• Due to the ability of tractors to be aggregated with many types of agricultural implements, Czech models effectively replace seeders, tillers, snow blowers and loaders.
• The presence of lighting and signaling equipment allows you to operate the mini-tractor at any time of the day.
• The low, in comparison with analogues, the cost is explained by the presence on the domestic market of exclusively second-hand samples, the price of which varies from 65 to 220 thousand rubles.
• The operator's seat is designed to be as smart as possible, making it easy to operate the machine for extended periods of time. The control levers are also very conveniently located, literally at hand.

The disadvantages of Czech technology include the low availability of spare parts and some inconvenience in using the plow. The latter are due to the design features of the frame, which has an articulated design. In addition, many owners complain about the lack of a cab, which significantly limits the operation of the machine during rain and strong winds.

Advantages and disadvantages of a mini tractor

Traktor tz 4k 14 is reliable and has a number of advantages:

1. Articulated frame. Makes the tractor maneuverable. Due to its high maneuverability, the model is used in open and closed areas with limited area;
2. The quality of the components. Czech-made tractor parts are made of durable materials. This increases the service life of the machine;
3. The versatility of the hitch. The model can be equipped with various assemblies and mechanisms;
4. Wheel formula 4x4. Increases the vehicle's cross-country ability;
5. PTO availability. The power take-off shaft allows the transmission of torque to the attachment;
6. Light and sound alarm. It makes it possible to use the tractor in poor visibility conditions.

The disadvantages of a mini tractor include an open-type control post.The absence of a roof excludes the possibility of working in the rain.

From the above it follows that the tz 4k 14 tractor, the technical characteristics of which are given above, is a high-quality model of Czech production. 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.

Video review of a Czech mini tractor with a Slavia motor

Below is a video review of the work of the Czech mini tractor TZ-4k-14

Michael:

I can boast of my Polish TZ mini tractor, which I got from my father and works as before. Some time ago, I completely went through it and replaced the checkpoint and something on the little things. The gears turn on smoothly and immediately, it starts up perfectly. I plow 25 acres of frost on it, I am glad that such a convenient design.

Alexander:

A neighbor has a wheeled deutz allis 9190-awd, and I bought myself a bush TK of Polish origin. We constantly compare in our work. This is not to say that I do not repair it regularly! But much less than my neighbor.It is difficult to find original spare parts, but I have already got used to it and use analogs. The main thing that had to be changed was the crankshaft, I made the box and changed the wheels, because the tread was worn out.

Advantages: powerful, functional.

Disadvantages: Parts are difficult to find.

The TZ 4K 14 tractor has a wide range of attachments

The Czech minitractor can be aggregated with various attachments, including a dump trailer, a harrow mower, a plow, a brush, 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, which greatly simplifies its unloading. The trailer has overall dimensions (L x W x H) of 2 630 x 1 700 x 980 mm. The mower, coupled with the TZ 4K 14, is the best option when it is not possible to use a conventional tractor with a side mower, for example in small areas, in parks or gardens.

A bulldozer blade is used to clear areas of snow or level the ground. A big advantage is the ability to quickly mount / dismantle the blade on a mini tractor and easy control of the unit. The blade has a width of 1,000 mm and a pivot angle of 45 °. With the help of a sweeping machine, dust is removed from sections of the road or other places. The drive mechanism is protected against dust ingress.

Another tool that can be aggregated 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 and has a working width of 250 mm. The plow is designed in such a way that the soil layer is laid to one side. 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 with a ripper. The maximum loosening depth of the machine is 6-8 cm, and the working width is 85 cm.

The versatile, comfortable and durable Czech-made TZ 4K 14 mini tractor 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 delight its owner, because frequent breakdowns during operation are excluded. The price of TZ 4k14 is about 175,000 rubles, although there are not many advertisements for the sale of these tractors.

Advantages and manufacturing disadvantages

The TZ-4K-14 model has obvious advantages:

• Sufficient traction and coupling parameters for towing trailers with a carrying capacity of up to 600 kilograms;
• The minimum set of sheds allows plowing the soil, sowing crops, caring for plants, harvesting, transporting goods;
• Most of the repair work is carried out without the use of special equipment, so you can fix the malfunction yourself. In addition, spare parts are affordable and can be easily purchased in a specialized store.

There is no full-fledged service of the mini tractor and the range of spare parts is limited. This problem can be solved by using consumables from other similar units.

It is also worth paying attention to the following shortcomings of the car:

• There is no independent power take-off shaft and safety arches;
• Small volume of the fuel tank, which reduces the autonomy of the unit;
• There are no ballast weights necessary to improve the traction of pneumatic wheels to the surface during plowing.

Device and purpose

Since the earliest modification of the Czech TZ-4K 10 unit was not exported to the Soviet Union, and only the TZ-4K 14 model received popular recognition, it will be appropriate to consider an overview of the design features of Czech technology using its example.

So, the TZ-4K 14 mini-tractor is a motorized self-propelled vehicle equipped with an internal combustion engine, transmission and chassis. The model is equipped with a single-cylinder two-stroke air-cooled diesel engine, capable of operating in any climatic conditions without the risk of overheating. This is due to its small size, which makes it possible to do without water cooling.

The check point of the mini-tractor has 4 reverse gears. Both axles are equipped with a differential, and on the front axle it is equipped with a locking function. The model is made in an all-wheel drive version, and the axles are interconnected by a swivel bushing. This allows them to turn 45 degrees relative to each other when the vehicle turns. Thanks to this design, the turning radius of the tractor is only 190 cm, which is why the model shows wonders of maneuverability in confined spaces, and the special fork design allows the axles to be lowered and raised at an angle of up to 11 degrees.

Moreover, the width of the front and rear track is adjustable and can vary from 70 to 100 cm. To increase the track width, loosen the nuts on the cast-iron hub, and then move it to the final position on the axle shaft. The machine's brakes are represented by two independent braking systems - front hand brakes and rear foot brakes. The clutch of the mini-tractor has a dry single-disc design and is activated using the left pedal.

The scope of use of Czech mini-tractors is quite wide.

The versatility of tractors is due to the compatibility of machines with any type of attachments and trailed equipment, as well as their maneuverability and high cross-country ability.

Power point

The manufacturer has equipped the tz 4k 14 tractor with a vertical single cylinder engine.

Power plant characteristics:

• The type of fuel used is diesel;
• Cylinder volume - 660 cm3;
• Maximum crankshaft rotation speed - 2200 rpm;
• Piston stroke from top to bottom dead center - 10.4 centimeters;
• Working cylinder diameter - 9 cm;
• Maximum power of the power plant - 13 horsepower;
• Fuel consumption - 210 g / h.p. in one hour of work;
• Installation weight 100 kg.

The motor is air cooled. The engine is cooled by a fan. The fan drive is belt driven from the crankshaft. The tractor power unit is started using an electric starter.

The electric starter is powered by a 12 volt battery. When voltage is applied to the electric starter, the drive gear engages with the flywheel of the power plant. After starting the engine, the drive gear disengages automatically.

Mini tractor TZ-4k-14 Deutz

The first models of small-sized garden equipment appeared at the beginning of the last century. The German company Siemens-Schuckertwerke, the Swiss SIMAR and the American Beeman Tractor were among the first to produce light models of tractors for land cultivation.

The development of mini tractors peaked in the years after World War II. Many, now well-known brands, for the mechanization of manual labor in farms, private households have developed many unique models of mini-equipment, which were the constructive basis for today's models.

Mini tractor TZ-4k-14 Deutz

The Czechoslovak mini-tractor TZ-4k-14 was produced in 1951 at the Agrostroj enterprise (Prosteev). It was the first mini tractor to appear in the Soviet Union. Popular models of mini tractors of other brands Deutz-Fahr, Mitsubishi, DongFeng became known in the CIS countries much later, in the mid-nineties.

The Czech mini tractor TZ-4k-14 was actively used in construction work before the Olympics-80.Due to its unique technical characteristics, the mini-wagon quickly gained wide popularity; some copies are still successfully working on personal plots. The device of the Belarusian MTZ-082 tractor was once copied from the Czech TZ.

Overview

The TZ-4k-14 tractor is an all-wheel drive unit with a four-wheel two-axle wheelbase, a foot brake is provided on the rear axle, and a hand brake on the front axle. It has a long service life, is easy to operate and maintain.

Mini tractor TZ 4k-14 Deutz

The TZ-4k-14 tractor is developed on the basis of the less powerful version of the TZ-4k-10. The first tractor models were produced with different engines, differing in power - the Slavia 1D80 fahr engine (9 hp) and 1D90TA (12 hp). Later, a 14-horsepower model was developed with a Slavia 1D80 B engine, wheeled Deutz-Allis 9190 AWD.

Deutz-Allis 9190 AWD Tractor

Features of the Czech tractor TZ Deutz:

• Selection of the optimal operating mode thanks to the 4FW / 4R reverse gearbox.
• Possibility of operation in row spacings thanks to an adjustable track of 0.7-1.0 m.
• High maneuverability thanks to the articulated frame with a turning radius of 1.9 m.
• The presence of differentials on both axles, the ability to lock the front axle differential with brakes.
• Effective work on steep slopes up to 12 ° due to a special design that partially follows the terrain and a clearance of 0.37 m.
• Plowing depth with a plow is 21 cm and a working width of 85 cm.

User manual

The Czech tractor TZ is distinguished by high reliability, good quality of units and mechanisms, economical fuel consumption of 210g / l, maintains stable operating parameters throughout the manufacturer's declared overhaul period.

First start

The recommendations of the operating instructions for running-in are to accurately and carefully test all working systems in the first 25-50 hours of operation. During this period, it is recommended to perform all work, avoiding increased loads, at reduced speeds.

After the recommended period, change the engine oil, transmission oil, engine oil filter, perform other manipulations in accordance with the manual.

Maintenance

Maintenance of a Czech mini tractor is reduced to the following simple steps:

• It is necessary to regularly clean the body of the minitractor from dust and oil stains.
• Monitor tire pressure.
• Adjust the clutch and brake pedals every 50-100 hours of operation.

At the end of the field work, conservation is carried out, namely:

• clean the tractor from dirt, dry it,
• draining oil and fuel,
• lubricate parts so that corrosion does not form,
• cover and put in a dry place.

It is safely operated due to the presence of signaling and lighting equipment.

Basic malfunctions and ways to eliminate them

Repair work of the TZ-4k-14 mini tractor does not require special equipment, so even complex breakdowns can be eliminated on our own. Much more problems arise due to the lack of a full-fledged service, the necessary spare parts, the owners have to use components, consumables from similar tractor models.

Diagram of the TZ-4k-14 Deutz minitractor

The clutch does not transmit torque:

• There is no pedal free play (you need to adjust it);
• The drive discs are worn out or have oil stains (they need to be replaced or cleaned);
• The discs on the splines are sticking (check their position and, if necessary, remove the jam).

The attachment does not rise:

• The oil level in the hydraulic system has dropped below the minimum mark (add oil);
• The hydraulic pump is off (turn it on);
• Hydraulic safety valve hangs up (disassemble and clean valve).

The brake is not working well:

• Pedal free travel has increased (adjust its position);
• The brake disc or pad is worn out (replace the corresponding parts).

Transmission overheats:

• Small gear or bearing clearance (adjust);
• Lack of oil or its poor quality (add oil to the required level that is suitable for this model);

Starter does not work:

• Broken or poor contact of the wire (solder or link it);
• Weak battery charging (charge it);
• Short circuit (clean the collector surface or replace the brushes);
• Poor magnetic switch contact (turn switch travel 2-3 turns).

Currently, service centers have appeared that are engaged in maintenance, the sale of TZ mini tractors after major and medium repairs, and the sale of spare parts.

Technical characteristics of the tractor TZ 4k 14

Due to its high technical characteristics, the mini tractor is widely used in various fields. It is unpretentious to working conditions and fuel quality. The model has the following characteristics:

Overall mass parameters

1. Weight of equipped minitractor without additional equipment - 870 kg;
2. Maximum travel speed - 16.5 kilometers per hour;
3. Length of the tractor from the hood to the rear edge of the hinged device in the raised position - 2750 mm;
4. Minitractor width - 1170 mm;
5. Steering wheel height - 1300 mm;
6. Track - the distance between the centers of the wheels of one axle - adjustable (from 700 to 1000 mm);
7. Clearance - 370 mm;
8. The smallest turning radius is 1.9 meters.

If you look in more detail - why did the Czech tz 4k 14 mini-tractor so attracted officials and collective farmers in Czechoslovakia and the USSR?

It is worth looking at the technical characteristics of this tractor. Nimble and compact - it could walk through the back streets of construction sites and hard-to-reach corners of agricultural plots. The ground clearance was 29 cm, the turning angle was 1.9 meters, the length of the entire tractor was 275 cm.

Before deliveries from Czechoslovakia, the smallest tractor in the USSR was the T-25. It was harder to drive than the TZ 4K 14 and more expensive.

The TZ 4K 14 minitractor was easy to operate and incredibly passable due to the articulated sun frame. As a result, driving this mini tractor was a real pleasure. The effect was further enhanced by the curiosity that this unusual machine aroused at first.

The engine of the TZ 14 mini tractor was originally a two-cylinder. The piston stroke of 85 mm created a thrust that construction workers, according to their confessions, did not expect from a small tractor. The engine power was originally 9 hp. This capacity was the Slavia 1D80, also produced by the Agrostroj plant.

But some modifications, which appeared in Poland and Hungary, brought the power up to 14 hp using the Slavia 1D90 engine.

The TZ4K14 minitractor was supplied with a four-speed reversible gearbox. The speed of the minitractor is 16.5 km / h, if you squeeze the gas all the way. The dry single-plate clutch makes the PTO dependent.

The tractor travel is heavy. Slowly but surely, the TZ 4K 14 mini tractor will plow the required area without breaking. But the performance is not impressive: the articulated sun frame reduces the tractor's pulling capacity.

The rotation of the machine occurs due to the movement of the frame, as in this video. So, although the machine is maneuverable, it is not stable enough to work with a plow.

But instead, the tractor performed well, working with a single axle dump trailer that had a removable tailgate. Its length was 2.6 m. The original trailer had a payload of 1000 kg, although we did not test it. As mentioned earlier, the TZ 14 mini-tractor has proven itself in the construction and cleaning of the territory. Blades and brushes are much better suited than agricultural implements.

The agricultural technique that went well with this mini tractor is a mower. You yourself understand that on a machine with such dimensions to work only in the garden 100 meters by 100 meters... Harvesting feed

Service

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

However, given that the average age of the models is more than 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 in time. In addition, it is necessary to regularly change the oil in the transmission system and tighten the block head bolts.

With intensive use of equipment, it is necessary to monitor the condition of the tread of the tires, to change their places for more even wear. Strict adherence to the recommendations for maintenance and operating instructions will ensure trouble-free operation of the mini-tractor, and 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.

The further fate of the tz 4k 14 minitractor

It is not difficult to buy such a device now. We constantly come across advertisements of people wishing to get rid of the Czech car.

But in the 90s, serial production ceased. This model was supplanted by AMZhK with hydraulics more powerful and smaller in size. It, in turn, was replaced by more modern Xingtai mini tractors, and then the Russian counterparts of the Fighter and SCOUT brands T-15. These models, while retaining their compact size, began to approach their full-size brothers in terms of parameters.

Mini tractors are a versatile technique that never ceases to delight its owners with many advantages. The range of this equipment is very huge and will delight you with its choice.

But today we will focus on the Czech-made mini tractor TZ 4K 14
