KhTZ-17221 from 1997 to 2015: technical characteristics, review, description

The HTZ-17221 tractor is agricultural equipment for a wide range of purposes. The machine, produced at the Kharkov Tractor Plant, is used during sowing and harvesting work, in urban agriculture, in enterprises and in road construction. Compared to other equipment used by farmers, HTZ-17221 is a fairly modern model. The first release of this series took place in 1997, its prototype was the T-150K tractor. The modernization made it possible to increase the productivity of the machine, make it more comfortable for the operator and reduce fuel consumption.

HTZ-17221: history of creation

The place of development of HTZ-17221 is the Kharkov Tractor Plant. More than one hundred thousand tractors for various purposes rolled off the assembly line of this production. The plant was developing not only tractors, but also all kinds of attachments. In fact, KhTZ was focused specifically on agriculture. In addition to wheeled tractors, all kinds of tracked vehicles were produced.

In 2006, the Kharkov Tractor Plant, in addition to the HTZ-17221 model under consideration, also produced modernized versions of the T-150, as well as the tracked HTZ-181. Machines for farming work – KhTZ-3510 – were in great demand. Since 2007, the plant's losses began to increase more and more with each reporting period. For this reason, KhTZ-17221 was no longer produced at KhTZ.

However, the Russian and Ukrainian markets are filled with a large number of spare parts. Moreover, both new and already used. It is not difficult to purchase a used HTZ-17221, both in working condition and for disassembly.

Historical reference

This tractor was developed at the Kharkov plant, which was a well-known manufacturer of tractors of various modifications and applications. In addition to tractor equipment, the plant produced mounted structures for universal tractors. The plant was oriented for agricultural needs and, in addition to wheeled tractors, produced tracked vehicles.

In 2006, various modifications of the T-150 tractor and HTZ-181 tracked vehicles rolled off the assembly lines of the Kharkov plant. However, in 2007, the plant experienced a serious financial crisis, from which it was never able to recover. In 2015, a decision was made to close the tractor plant, which was the reason for the cessation of production of KhTZ-17221 in Kharkov.

Tractor modifications and operating characteristics

All varieties have no design differences; the difference mainly lies in engine power. This fact led to an increase in the fuel tank and the movement of individual components. There are 3 modifications in total:

• HTZ-17221;
• HTZ-17221-21;
• HTZ-17221-19.

The practice of using this tractor has shown that after 3 years of systematic operation there is noticeable wear on the input shaft located in the gearbox, which leads to its replacement. After 4 years of constant operation, the hydraulic coupling responsible for engaging 3rd gear becomes unusable. The metering pump located in the steering system should be regularly monitored. In addition, you have to periodically replace the clutch discs.

Specifications

Before purchasing the tractor model in question, you must carefully familiarize yourself with its performance characteristics.

Dimensional and mass indicators

At the moment, both the weight and overall dimensions of the HTZ-17221 depend on the specific modification. They look like this:

Overall dimensions differ significantly due to the use of engines of various modifications, as well as differences in the basic configuration. The design differs depending on the purpose of the specific type of tractor.

Engine

Today, depending on the modification, the HTZ-17221 can use different engines. At the moment, the following units can be installed:

• YaMZ-236D-3;
• YaMZ-238KM2-3;
• D-260.

The main parameters of these units are as follows:

Transmission

In HTZ-17221 only a manual gearbox is installed. There is a special hydraulic drive that reduces the required force to a minimum.

The checkpoint has the following parameters:

• a hydromechanical drive is used;
• There are 12 speeds to select the optimal driving mode;
• switching on the go is possible - no interruption of movement is required;
• total number of forward speed ranges/speeds – 3/12;
• total number of reverse ranges/speeds – 0.25;
• the main gear is conical, it includes a spiral tooth and a cross-axle differential;
• The crank gear is in the form of a single-stage planetary gearbox.

There are also some features depending on the type of motor used:

Chassis (transmission)

On the KhTZ-17221 used today, the transmission consists of:

• dry, single-plate clutch;
• hydromechanical gearbox.

Also an integral part of the transmission is the power take-off shaft. It is located at the rear and has as many as 2 speeds. The speed range of some modifications of the HTZ-17221 is quite large even compared to foreign analogues:

• 8 speeds for reverse movement;
• 16 forward speeds.

Cabin HTZ-17223. Tractor control

One of the main advantages of this tractor is the cabin. It is equipped with the following:

• double-glazed windows - it is possible to operate the equipment even at low negative temperatures;
• air conditioning and heating systems - which increases labor productivity, since driver fatigue is reduced during work.

All controls are located within reach of the driver. The KhTZ-17223 cabins of the last years of production before the liquidation of the plant have some shortcomings:

• poor sound insulation - immediately after purchase it is worth laying another layer of special material;
• there are holes in the cabin connecting the engine compartment to the cabin - they need to be sealed;
• The windows should be redesigned so that they open in the other direction, in the direction of movement of the tractor (otherwise all the dust will end up inside the cab during operation).

Device

Among other things, unlike the basic version, the machine from the Kharkov Tractor Plant has a number of design features. In particular we are talking about the frame.

Frame, power plant

In essence, KhTZ-17221 is a heavily modernized T-150K. A special feature of this tractor was its breakable frame, consisting of two half-frames connected by hinges. These hinges allow you to change the angle of position between the half-frames in the vertical and horizontal planes.

The power unit is installed on the front half-frame. For this modification it is YaMZ-236M2. The power plant is covered on all sides by the hood; there are two removable side panels for access to the engine.

The clutch housing is attached to the engine. The clutch itself in HTZ-17221 is frictional, using one driven disk. The clutch control mechanism is additionally equipped with a pneumatic booster.

Dimensions

Operating experience. Advantages and disadvantages

The model of wheeled tractor for agriculture under consideration has both its advantages and disadvantages. If possible, before purchasing, you should familiarize yourself with the complete list of all the weak points of this equipment.

During the first 12 years of operation, the following components and parts fail :

• water pump - circulating through the cooling system;
• cuff of the pump that pumps fuel (2 times in a row);
• bearing seal (rear main).

Users have the following main comments regarding the tractor itself:

• after 3 years of operation, the input shaft of the gearbox was replaced;
• after 4 years, the hydraulic clutch for engaging the third gear was replaced;
• The steering metering pump was replaced;
• The feredo, one of the clutch discs, has been replaced.

Attention should be paid to the main disadvantages of the type of tractor under consideration:

• poor ventilation, noise;
• it is possible to open only the side windows;
• when driving, dirt flies off the front wheels and enters the cabin;
• After 2 years of operation, the rear fenders will need to be replaced.

The cable control of the units does not show itself well. If possible, it is worth converting it into a lever one.

The issue with ventilation and heating is solvable.

It is possible to dismantle the stove and install a special air conditioner in its place, with additional air filtration.

The main positive aspects of the HTZ-17221 tractor include the following:

• unpretentiousness to fuel quality;
• endurance and engine power - even a 180-horsepower tractor is superior in performance to its analogues;
• ease of repair - almost all breakdowns can be eliminated on your own with minimal knowledge and skills in repairing such equipment;
• All design and assembly shortcomings can be eliminated with your own hands - while spending a minimum amount of time.

Reviews

• Nikolay, Leningrad region. The car was manufactured in 2014 and was purchased for 1 million rubles. In good condition, with all options and attachments. The machine is supplied with a tow hitch with a load capacity of over 4 tons. The equipment works well, but it requires regular maintenance. Something is constantly leaking, something will fall off somewhere, somewhere a part needs to be greased or replaced. In general, before each trip to the field you need to check the tractor, and then it will never break down in operation.
• Gregory, Kharkov. A good tractor for domestic conditions. All spare parts are available for this model. Good maintainability and a comfortable cabin, high performance of the 220-horsepower version, which is very cool for a tractor at this price. The machine is widely used in agricultural work. Thus, with timely maintenance, the HTZ 17221 can properly cope with hilling and harrowing soil, plowing and loading, towing heavy trailers, etc. There are also plenty of disadvantages - engine overheating, endless noise and vibration. Moreover, the vibrations even extend to the steering column and seat. The chair itself is uncomfortable, after many hours of work your back becomes stiff and hurts, but you can live with it. The machine moves confidently on muddy soil, which is very important when cultivating the soil. My farmers and I are used to this tractor because it is cheap and there is simply no affordable alternative to it.
• Konstantin, Ekaterinburg. A good car for everyday tasks. There are many factory defects that you can fix yourself. This tractor is like a construction kit that can be converted to suit you. Minor breakdowns occur almost every day, but all major components and assemblies have never been repaired or overhauled. There are also some problems that can be overlooked, and this is only possible with our tractors.

Prices for used tractor HTZ 17221

The cost of the type of tractor in question on the secondary market depends on two different parameters: year of manufacture and operating hours.

Before purchasing a used tractor of this model, you should familiarize yourself with all possible breakdowns in advance and pay attention to weak points. In the future, this will avoid unnecessary investments in tractor repairs. Low cost may be the reason for the high cost of repairing equipment.
