The invention discloses a film uncovering machine for recovering mulching film and a control method thereof. The machine comprises a machine frame. Walking wheels are arranged at the lower portion of the machine frame. A handrail rack is arranged on the machine frame. An installation shaft is fixedly installed at the upper portion of the machine frame in the horizontal direction. Two ends of the installation shaft extend to the left and right sides of the machine frame respectively. Two rolling cylinders are placed on two ends of the installation shaft movably in a sleeve mode. Two motors are arranged on the machine frame for driving the corresponding rolling cylinders to rotate. A controller is arranged on the machine frame for controlling two motors. When the device detects that the walking wheels rotate, the controller controls two corresponding motors to output the torques based on the detected tensile force borne by the two rolling cylinders respectively. The film uncovering machine for recovering mulching film can recover all the mulching films on two ridges, and prevent the mulching films from breaking because of ultra-large torques. The machine is applicable to the operation in mountainous and hilly areas, and can greatly enhance the film uncovering efficiency.
