The working process of soil cultivation by disc cutters of furrow openers of sod seeders was analyzed and the main disadvantages were identified: unevenness of the torque transmitted by them due to impact loads and high-energy consumption. An original design of a damper-safety device is proposed, allowing to eliminate them. A 3D model of the output shaft of a furrow opener with two disk cutters equipped with L-shaped knives, each of which is equipped with a damper device, is developed. Computer modeling of the milling process was performed in the ANSYS Rigid Dynamics program, during which the parameters and operating modes of the damper device were determined, in which its operation is most effective. To reduce the magnitude and unevenness of the torque, it is necessary that the sequence of the disk cutter knife entering the soil is performed at the moment when the force on the knife of the second cutter, finishing the cutting process, is 5 ... 15% of the maximum. Damping devices reduce the maximum torque consumed by cutters relative to the load torque by 49.4% with an amplitude of oscillations of the spring compression value of 1.2...1.6 mm in the case of a damper spring stiffness of 50...70 kN/m, a rotation frequency of 400...500 min-1 and a number of knives of 2...3 pcs.
