For several years the Research Institute of Vegetable Crops worked on development of new technology of vegetable crops cultivation on the ridges. As results of this activity designed were some machines for ridge formation and seed sowing, mechanical equipment for installation of subsurface drip irrigation and for weed control. The weeder is equipped with regular winged blades to weed control between ridges and with active set of rotors to kill the weeds on the sides. The weeder has special hillers allowed to recreate original shape of the ridges at the same time. Field tests carried out at different soil and moisture conditions proved successful weed control and proper ridge shape recreation. The best weeder operation was on medium moist soil.
