Description

Technical Field

[0001] The utility model relates to the technical field of tractor brackets, and specifically discloses a tractor bracket. Background Art

[0002] A tractor is a self-propelled power machine used to tow and drive working machinery to complete various mobile operations, and can also be used as a fixed operation power. It consists of systems or devices such as an engine, transmission, running, steering, hydraulic suspension, power output, electrical instrument, driving control, and traction. The power of the engine is transmitted to the driving wheels by the transmission system to make the tractor run. In real life, common ones use rubber belts as the medium for power transmission. Tractors are classified into agricultural, industrial, and special-purpose tractors according to functions and uses; and into wheeled, crawler-type, boat-shaped tractors, and self-propelled chassis according to structural types. The tractor bracket is one of the components of the tractor.
