Tractor t 40 am
The Soviet tractor industry was well developed and had a wide range of models that were used in completely different conditions and for solving many problems. The model LTZ T 40 am was produced from 1961 to 1995 at the Lipetsk Tractor Plant, which became one of the main in part of the regions of the USSR.
T 40 AM is designed for plowing and processing light soils, various works in greenhouses and gardens, it successfully cultivates row crops, and also installs a stacker, a snow dump on it, and with its help it is possible to carry out transport operations. The production of the tractor was initially aimed at creating a medium-sized machine for agricultural work of a universal nature, capable of plowing as well.
Specifications
According to its characteristics, the T 40 am tractor is an all-wheel drive modification of the basic model LTZ T 40. The engine is started with an electric starter, while on the earliest models this was done using a PD8 starting gasoline engine.
The mechanical four-way transmission has eight speeds, a creeper and a differential lock. Reverse allows the tractor to move back and forth in all gears. The location of the gearbox shafts is one of the key design features of this model. Also, the brake of this tractor is located in the transmission and works according to the retarder principle.
The tractor has enough power and speed to fulfill the assigned tasks, which is provided by its weight of 2,595 kg and an engine power of 50 hp. with. in conjunction with the existing transmission.
Engine characteristics
On this model, the D-144 engine was installed, having a power of 50 liters. with. (36.8 kW). D-144 is a four-cylinder in-line four-stroke air-cooled diesel engine used on a number of special equipment. The displacement of the cylinders is 4.15 liters with a torque of 221.4 Nm, and the torque reserve factor is 15%. The engine produces its characteristics, consuming 242 g / kWh. The engine develops its maximum power at 2000 rpm.
Fuel supply goes by means of an in-line all-mode fuel pump, closed injectors and a multi-layer atomizer. Coarse and fine filters are easy to replace and fit from many other tractors.
The lubrication system for moving parts works by splashing oil on these very parts. The oil is cooled in a separate radiator, which complements the forced air cooling due to the release of some of the heat through it. The lubrication system also has an engine driven oil pump and filter.
The cooling system works forcibly due to the fan, which is triggered when a signal from the temperature sensor is received.
Cabin
The location of the tractor cab is rear, closed type design, single. It is made of stamped panels that are connected to each other by spot resistance welding. The frame is tubular, which is made for the safety of the driver in the event of the tractor overturning.
There is a heating system inside for winter operation. The viewing radius is very large, which is convenient for any kind of work. 90% of the walls are glass; a windscreen wiper is provided on the windscreen.
The door is located on the left in the direction of travel of the tractor. The cab contains all the main controls for the machine.
Fuel consumption
A 40 am tractor consumes 15 kg of fuel per hour during arable work, while the nominal consumption is 7.2 kg per hour.
Device
In general, the T 40 am is not the most complicated tractor. From electrical equipment, it has a generator, an electric starter, a battery, a pneumatic compressor, sometimes there is a hydraulic system, as well as lighting.
Advantages and disadvantages
Quite a long time has passed since the release of this tractor and, given that it is actively used to this day, its first advantage is its endurance. The D-144 motor has several key advantages: the generator produces a three-phase current, which does not require an additional rectifier, but a relay-regulator is used.
The single plunger pump provides fuel savings over similar models.
Among cons tractor, the following can be noted:
- Steel exhaust manifold, which over time begins to burn out and let smoke through;
- To adjust the fuel pump, you need a special key, without which it is very difficult to get to it;
- The oil consumption is such that it needs to be topped up at intervals of 2-3 months;
- The oil is often forced through the crankshaft oil seal.
