The MTZ 1523 tractor model left the production lines of the Minsk Plant in 2009. The development of the model was the result of the implementation of a set of improvements and upgrades to the MTZ 1221 tractor. The purpose of creating the machine was to maintain a competitive position in the global tractor market, as well as to produce a universal high-performance machine with a wide use, including all types of tillage and agricultural work, plus the use of a tractor in public utilities, construction and other industries. The use of hydroelectric engagement drives in the designs of transmission units and equipment of the machine made it possible to improve the ergonomics of the tractor control and its performance. The skeleton of the machine has a traditional semi-frame design of a wheeled tractor. MTZ 1523, 1523V became the two basic versions of the series. The 1523B machine is designed for continuous use in reverse mode. It features an additional reverse control post with a swivel operator's seat and duplicate controls: clutch, fuel supply, brake, rear steering column. The subsequent evolution of the model in the modification 1523.3, 1523B.3, 1523.4, 1523.5 is to increase the environmental standard of the machines.
The tractor belongs to the third traction class with power from 148 to 155 hp. depending on the modification of the model. With its performance and use in wide-cut tillage units, the machine successfully competes with a tractor of a similar class of the KhTZ T-150, T-150K brands. At the same time, the MTZ 1523 fuel consumption is 30% less, and the machine also differs significantly in the level of comfort and ergonomics of the operator's workplace.
Engine
The tractor is equipped with a turbocharged, six-cylinder D-260 diesel power unit with a cylinder operating order of 1-5-3-6-2-4. The abbreviation "1S2" in the modification of the unit indicates the equipment with intermediate cooling of the air blown by the turbine. The motor is operated with a rated torque safety factor of 15-25%. The engines are equipped with six-plunger in-line fuel pumps of the Motorpal brand manufactured in the Czech Republic or Yazda - Russia. And also the unit is completed with two types of turbocompressors of the brand "Turbo" - the Czech Republic and OJSC "BZA" - Belarus. Automatic control of the thermal regime in the cooling system is carried out by two thermostats.

Dimensions
MTZ-1523 at first sight fascinates with its appearance and size. The device looks especially impressive when twin wheels are installed on it.
But, despite the impressive dimensions, the tractor turned out to be maneuverable. The designers achieved this by reducing the wheelbase and the minimum turning radius.
To compensate for the loss of controllability when attaching heavy implements, weighting agents weighing slightly more than a ton are provided.
Cabin
The operator's workplace in this series has been tried to be comfortable for the operator.
- The cab received a rigid steel frame that protects the operator when the machine rolls over.
- Cylindrical tinted glass gives the cabin an extra beauty.
- Maintaining a comfortable temperature inside the cabin, the designers assigned to the ventilation system. It works in 2 modes: blowing and heating.
- By separate order, it is possible to install an air conditioner that will cool the blown air.

Major faults and repairs
One of the priority features when choosing an MTZ Belarus tractor is the ability to quickly perform the necessary repairs in the field. During the operating period specified by the manufacturer, the unit is characterized by stable operation, regardless of the intensity of use. The maintainability of components and mechanisms is quite high.
According to numerous reviews of machine operators, the ratio of price and quality is optimal. And malfunctions and breakdowns are caused, most often, by improper operation, negligence in work, illiterate maintenance, and incorrect use of attachments.
Advantages and disadvantages
The release of the machine, its subsequent operation and maintenance are focused on the economic trend of the general globalization of the world market. High-tech machine components require repairs in the manufacturer's service network, which has an appropriate specialized material base and staff qualifications. The MTZ 1523 tractor is a complex, high-tech machine that requires appropriate professional training and operator qualifications.
The engine of the machine is equipped with a powerful radiator that eliminates overheating at maximum speeds and loads. Taking into account the additional fuel tank, the tractor has a sufficient regular filling volume of fuel. The place of work has a convenient placement of controls and good noise and dust isolation providing comfort. The cab with spherical glazing provides maximum visibility to the driver of the machine. The rear linkage of the tractor is equipped with a sufficient set of universal coupling and traction devices for fast and reliable connection with the machines used.
The release of the MTZ 1523 machine is the result of the strategy of the enterprise's participation in the formation of the world market for agricultural machinery. The confirmation of the course is the certification of all manufactured equipment in accordance with the standards of the European Union. In 2000, the Minsk Tractor Plant confirmed the level of production quality by obtaining a document of conformity according to ISO-9001. World standards have been confirmed by a certification audit carried out by the German company TUV-Thuringia.
Device
The tractor has an improved undercarriage with front wheel drive, which have a smaller diameter than the rear ones. The driven axle is equipped with large-diameter wheels and acts as a rear half-frame. The machine is controlled by a friction clutch. To reduce the pressure on the ground surface, it is possible to install twin wheels, which are equipped with disc brakes.
This model of the machine has a reproductive hydraulic system from the German company Bosch. It provides the possibility of successful interaction of the tractor with various agricultural equipment and other attachments in the most difficult working conditions.
