The ridging and film laying machine is a work tool driven by the power output shaft of a tractor. It uses the combined motion of the rotating blades on the rotary tiller shaft and the forward movement of the tool to carry out rotary tillage, ridging, fertilization, and film covering operations on uncultivated and plowed fields. Its performance characteristic is strong soil crushing ability, and one rotary tillage can reach several times that of a typical plow and rake. It can not only perform rotary tillage and ridging, but also complete the tasks of rotary tillage and ridging, fertilization, mulching, and laying drip irrigation belts.
