Currently, there are changes in climatic conditions: abrupt changes in temperature, humidity, strong winds, etc. Returning frosts are still possible in our zone until the end of the first decade of June. Climate variability affects the productivity of agricultural crops. For sustainable development of crops and the creation of favourable conditions for the growth and development of plants, and obtaining an early harvest, we can use the technology of covering early potato plantings using film stackers. There are various designs of film stackers, but there are features of covering the film along the ridge for growing early potatoes. Taking into account the peculiarities of growing potatoes on the ridge and covering the plantings to obtain early production was the goal of our work. A film stacker is proposed, which is adapted to the ridge technology of potato planting. The device works in the following way. When the film stacker passes over the field, a reel with the film or covering material is unwound. The covering material is pressed with a roller and then, due to the levelling fingers, is laid over the row, followed by the closing working bodies, which pour a loose layer of soil on each side on the edges of the film. A dense roller is formed, which securely fixes and presses the edges of the film to the soil. The design features of the film stacker reduce damage to the film and improve the quality of covering the ridges of early potato plantings, which provides an optimal water-temperature regime for plants in the first period of plant growth.
