Tractor T-40 - a wheeled station wagon with ample opportunities
The design of this machine takes full advantage of the classic layout of wheeled tractors, air-cooled and reversible mechanical transmission. Thanks to the advanced performance characteristics for its time, the T-40 tractor in several modifications was produced from 1961 to 1995 of the last century.
For three and a half decades, 1,200,000 units of tractors of the 0.9 traction category, which are in high demand in agriculture, industrial construction and municipal services, rolled off the assembly line.
- The 40th model LTZ (KhTZ), universal in many parameters, is aggregated with a variety of attachments and trailed equipment designed for soil processing and maintenance of industrial crops, loading and unloading bulk materials, snow removal, transportation on unpaved roads.
- The popularity of the "forty" is determined by the high efficiency of operation, the presence of a reversible power train that allows you to fully utilize the entire range of forward and reverse speeds, compatibility with working units designed for a light tractor and a more powerful one.
T-40 and its versions are still successfully working in the private sector and specialized farming enterprises. All-wheel drive steep-slope modifications, as well as general-purpose vehicles, are characterized by increased maintainability, since spare parts and whole units of different models are unified.
T-40 device
This tractor is characterized by a classic semi-frame layout for small cars with a load-bearing gearbox body, a rigid rear axle mount with large-diameter drive wheels and a sprung front axle suspension. single all-metal with a rigid inner frame and a standard set of equipment.
The high cross-country ability of the machine is provided by the lugs of the herringbone-type wheel tires, the ability to adjust the track and ground clearance. To work in row spacings, it is proposed to use the advantages of narrow-profile wheels. After minor modifications, the tractor chassis can be equipped with twin wheels.
Specifications
The basic machine has a well thought-out layout, so its dimensions are within the range of 3.66 x 1.62 x 2.1 meters. The road clearance is 50 cm, depending on the type of work, the track can be adjusted in the range of 1.2-1.8 meters, the dry weight of the tractor is 2369 kg.
Engine
Developed by the best designers of the Vladimir Tractor Plant, the power units are presented in several versions. These are 37-horsepower air-cooled diesel engines D-37 and more powerful within 50 hp, D-144 power units. In the operating speed range, the average fuel consumption is 6 - 7.7 l / h.
- Various modifications of power units are started from the driver's seat or by carburetor starting engines.
- The transmission is connected to the engine via a mechanically controlled disc clutch. It includes a bevel gearbox,.
- The range of working and transport speeds is in the range from 2.24-26.65 km / h, when switched on, the minimum speed is 1.6 km / h.
It is recommended to fill the tractor with M10DM oil in the amount of 10 liters, which is just enough for a year. The durability of the transmission largely depends on the timely fulfillment of the requirements of the Maintenance Regulations. In particular, the winter or summer transmission oil of the T-40 tractor must be replaced when preparing the machine for winter or summer operation.
Driven by a multi-mode PTO shaft. Another side PTO is used to activate stationary units, pumps, grain crushers or. The tractor is also equipped with a hydraulic system of a separate-aggregate type with a productive gear hydraulic pump and a spool switch for operating modes.

Advantages and disadvantages
Relatively inexpensive, simple in design and economical in everyday operation, the “forties” have earned the respect of users due to their versatility, unpretentiousness to fuel and lubricants, and long overhaul life.
Due to the wide choice and affordable cost of the repair and restoration and consumable assortment, tractors produced in the 80s-90s are still maintained in a technically sound condition.
- The passability of the machine on weak and waterlogged soil bases is also highly valued.
- The combination of small dimensions and excellent maneuverability, which determines the possibility of using the tractor in the interior of greenhouse and livestock complexes.
- Self-service and repair availability.
- Availability for all steps of the checkpoint.
Among the main disadvantages, it should be noted the problems of cold start, low efficiency of the air cooling system, lack of full thermal and sound insulation of the cab, high driver fatigue due to the rigid rear axle suspension and high vibration levels.
The design of the "forty" does not provide for the control of the braking mechanisms of the towed trailers, which in turn initiates accelerated wear of the brakes of the tractor itself. Also create inconvenience strict restrictions on the temperature conditions of the engine and the time of its operation at low and idle speeds.
Price of the T-40 tractor and its modifications
The last “forty rolled off the assembly line more than 20 years ago, so there is practically no chance of buying a car with zero mileage. A more realistic option is to purchase a used tractor that can work out the rest of the overhaul life without additional costs of material resources and working time.
The cost of a tractor of the 40th model, taking into account its condition and configuration, is 70,000-100,000 hryvnia (2,500 - 4,000 $). When buying, it is advisable to make sure that all components and assemblies are in good working order, there are no extraneous noise in the engine and transmission, as well as cracks and swelling on the tires of the wheels.

Analogs
In this segment there are models of the same type, Minsk tractors and Yuzhmashevsky ones. From the imported assortment, several tractors made in China that are identical in performance can be named.
