Light tracked tractor is a new type of agricultural machinery developed to solve the problem of conservation tillage in paddy fields, especially in hilly areas. The machine has a compact structure, innovative design, and adopts static hydraulic transmission, achieving stepless speed change and easy and flexible operation; The unique rubber track triangle transmission improves the ground clearance of the machine, making it highly passable through paddy fields, reducing damage to the bottom layer of the field, and achieving protective tillage of paddy fields; A mature semi split three-point hydraulic suspension device can be matched with different agricultural machinery to achieve tasks such as plowing, rotary tillage, ridging, trenching, soil cultivation, and field transportation, with good work quality and high efficiency.
