What is the difference between a tractor and an excavator?
Today, more than 100 types of special equipment are known. These mechanisms are widely used in various fields of construction, industry and agriculture. For decades, the most common type of special equipment was tractors.

Functional features of the tractor
Tractors are examples of self-propelled special equipment used to perform various tasks as additional equipment is installed. The design of mechanisms includes main and auxiliary systems and components. The function of the main system is to create traction and provide manipulation of attachments.
The main systems include:
- Power plants (diesel engines);
- Infection; Infection;
- Chassis;
- Working equipment.
The engine creates torque, the transmission transmits it to the wheels and sets the movement mechanism in motion. Auxiliary systems ensure the activity and safety of the main nodes. The working equipment is a hydraulic articulated system, which ensures the connection of the tractor with mounted and semi-mounted machines and their operation; The STS consists of a linkage and a hydraulic system. To ensure the operation of the working equipment, the tractor must develop high traction force at low speeds.
These requirements require special designs.
- Use of diesel engines to provide more torque at low speeds;
- Numerous programs;
- Special equipment is designed for off-road travel, so the contact area of the wheels with the soil is of great importance;
- Using ballast weight to increase traction;
- Installation of power shafts to supply energy to the hinge and traction units.
Depending on the type of movement, there are two types – wheeled and tracked tractors. The first option can be used on ordinary roads, but on loose soil the equipment may slip. To avoid this, some models have all-wheel drive. The large mass limits the range of use, as the equipment compacts the soil. For particularly heavy samples, double or engineered wheels are available. Caterpillar tractors have more towing capacity. The main disadvantage of this technique is the inability to move asphalt, since the tracks destroy the coating. These models are used in agriculture.
Tractor Application
Depending on the area of use, tractors can be divided into agricultural, industrial and friction. Features of operation are reflected in the design of the models. In agriculture, special equipment is used for seasonal work and for various types of operations that cover large areas.
Designs must include:
- Quick replacement of hinges or trailed equipment;
- Other mechanisms during harvesting;
- Integration of connecting devices;
- On-site maintenance and repair.
Industrial tractors are used as bases for construction equipment such as bulldozers, scrapers and pipe layers.
Operational features of industrial models:
- Use of one type of trailed equipment;
- Operation at low speeds;
- Ability to move on hard and flooded ground.
Many varieties are delivered to the work site using special equipment. Skip tractors are used to transport trees from their location to the storage area. A platform with a winch is attached to the rear of the frame.
What is the difference from an excavator?
- Tractors are specialized equipment with a wide range of uses; excavators are used on construction sites, in the development of mineral deposits, in laying roads and in public utilities;
- The main difference between excavators and tractors is the presence of buckets (full-time, schedule, loaded, free and bucket). Excavators also have booms, coordinated masts and arms, including the ability to install a variety of attachments to expand the range of applications;
- Excavators differ from tractors in power. The equipment is not designed to be moved. The engine power is transmitted to the booms and bucket.
There are much more tractors everywhere. These machines perform a variety of tasks: construction of roads and other structures, agriculture, telecommunications repair, emergency rescue work, etc. Many people do not think about the legal side of the issue, that is, what category of equipment tractors belong to.
To drive a tractor you will need a driver’s license with a certain category. You have the opportunity to study at a specialized school and receive a certificate only by passing an exam. Some people think it’s easier buy a tractor license and get a driver’s license without passing an exam, but in this case we must not forget about criminal liability.
