Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a suspension mechanism for a tractor. Background Art

[0002] Tractors are the core machinery of modern agriculture and are widely used in a variety of agricultural operations such as tillage, sowing, fertilization, spraying pesticides and harvesting. They provide the necessary power and versatility to make agricultural production more efficient and automated. With the development of agricultural technology, the design and function of tractors are also constantly improving to meet the growing needs of agricultural production. The suspension mechanism of the tractor is one of its key components, which is mainly used to connect various agricultural tools and accessories, such as plows, harrows, seeders, etc. This mechanism is usually based on a three-point suspension system, including two lower arms and an upper arm. This design allows for the rapid replacement of different tools, which improves the versatility and flexibility of the tractor. The suspension mechanism is usually equipped with a hydraulic system to adjust the height and angle of the tool to ensure the precise execution of various operations.
