The SF-502 light tracked tractor is a power machinery developed to solve the problem of protective tillage in paddy fields. The machine has a compact structure, innovative design, and advanced technology of static hydraulic transmission, achieving stepless speed change; Adopting hydraulic steering, the steering and tool lifting are operated by one lever, making it easy and flexible to operate.
The unique triangular track transmission improves the ground clearance of the machine, giving it high passability and strong resistance to subsidence in paddy fields, reducing damage to the bottom layer of the field, and greatly protecting the soil, soil quality, and environment, achieving paddy field protection and cultivation.
The mature 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 operation. The quality and efficiency of the work are good, making farmland operations easy.
