The structural dimensions and weight of the Keith OPTUM series tractor are currently among the most functional tractors in the same horsepower range in China. This series of tractors is specifically designed for medium to large scale customers, such as plowing and deep loosening. The continuously variable transmission can maximize fuel economy. In order to meet customers' needs for retesting operations, the whole machine can be equipped with front power output, remote output valve, and front suspension, which can be applied to triple lawn mowers, compound land preparation operations, and so on.
