Tractor in agriculture

tractor Use in agriculture

tractor - is a separate view of the vehicle, wherein a low speed motion and high traction force. The main application of the tractor is agriculture, where it is used for plowing, as well as to move the tools and machines that are not on the go. Tractors may be equipped with both half and semi-mounted equipment

are two main types of tractors:

  • wheel;
  • Track
  • ..

Each of these species has not only the advantages but also disadvantages.

Wheeled tractors often used on public roads, so that they are capable of high speeds and at the same time be low thrust. The use of such tractors on loose soil leads to skid, which is eliminated by the all-wheel drive. But such machines are significantly lose weight and, as a consequence, greatly subside into the ground. Therefore it is necessary to significantly increase the width of the tractor tires in order to reduce the pressure on the soil

As for track-type tractors, they have a much greater traction than the wheel, but they have a great disadvantage. They do not can move forward on a paved surface without destroying it in the process. The only exceptions are tractors with rubber-tracks. With a small movement speed which is 30 - 40 km/h, crawler tractors have also significantly less pressure on the soil surface. This is due to the large contact area of ​​the tracks with the ground, and the weight of the tractor is the same as that of the wheel.

Crawler tractors are widely used not only in agriculture but also in industry, due to its undemanding.

depending on the application, the tractor are significant differences between them and are separated on:

  • agricultural;
  • industrial;
  • skidder .;
  • army

The main requirements that apply to agricultural tractors, due to their seasonal work and larger work areas are as follows:

  • ability to quickly change attachments or towed equipment;
  • ability to work and movement at higher speeds while maintaining operability with other machines at minimum speed;
  • ability to unify the connecting devices;
  • a tendency to maintenance and repair in the field.

For real ization of the above requirements the following engineering solutions are used:

  • Engine applications with increased speed;
  • the use of a multi-stage gearbox;
  • ability to establish the creeper;
  • use sprung suspension;
  • application unified rear curtain system

Agricultural tractors are divided into:

- Root Crops which are intended for soil treatment after intertillage. The main feature is that they are able to pass between the rows, which makes them able to carry out plowing in gardens and greenhouses

- general purpose, which are of two types:
1. Arable - Tractor designed for continuous tillage of soil on the fields, have thrust class 3-10 ton-forces and power consumption of 25-30 horsepower per 1 ton-thrust. This type tractor has shifted the center of gravity forward, whereby uniform distribution of the weight carried on the entire track length when working with the plow.
2. Vehicles - tractors, which are used for transportation of goods, using trailers. This type of wheeled tractors happens only, while it can develop sufficiently high operating speed: 50 km/h. The main feature of transport tractors is that they combine the properties of both arable and transport tractors.

Industrial tractors are in most cases the basic machine in excavating or building unit. For this type of tractor is characterized by the following properties:

  • ability to use throughout the life of the one and the same type of work equipment;
  • ability to operate at low speeds with a high traction force in a slip;
  • ability to work on solid ground;
  • ability to run on too wet ground;
  • the need for strict positioning of the working body with respect to the soil;
  • delivery to the place of work on special transport

The following engineering solutions have been implemented for the realization of these characteristics:.

  • use engine with low revs and high torque torsion;
  • use converter tractor 15 traction class;
  • application gearbox with gear constant mesh, blurring which occurs under pressure;
  • use of rigid (or semi-rigid) suspension;
  • use the chassis and frame, in Silenus construction;
  • use the armor for the hood and the bottom of the engine compartment. Which serves to protect the motor;
  • the use of reinforced hinges that serve for mounting the blade, hydraulic cylinders and ripper;
  • the use of hydraulic equipment, which has increased energy consumption;
  • improved visibility from the cab;
  • ability to operate at low temperatures

The main distinguishing feature of this type of tractor is presence rearward displacement of center of gravity, which serves for the uniform distribution of weight on the entire track length. .

Skidder - a tractor, which is under construction, as a rule, on the basis of a farm tractor and differs from it only in the layout, which allows you to put a platform on the back of the frame. The cab and the engine are placed in front of the tractor, and behind them a platform serving for forest skidding. The main characteristic that distinguishes the skidder from other types of tractors is the presence of the running gear with large contact area, thereby reducing the impact of erosion on the forest floor.

Earlier tractors were used not only in agriculture and industry, but also in army combat units. Army tractor used to tow artillery and other weapons systems trailed. The essential requirements that apply this type of tractor, has high speed, high throughput, adaptation to different climatic conditions. Typically, Army tractor is a machine that combines the properties of the agricultural and skidder. Nowadays, this type of tractor is used very rarely, this is due to their low tactical and technical characteristics, so now the army of the tractor are used except in the Royal Engineers.
