Trailed type offset disc harrows with hydraulic lift are trailed type machines used for cutting and shredding plant residues (corn, sunflower, wheat, etc.) and weeds and breaking the duff layer after harvest. These machines prepare the field for direct sowing without using another agricultural machine by cultivating the soil without clods in the dry months when the plows cannot be used after the harvest. Model KTGD type offset disc harrows prevent wind and water erosion while disrupting stubble.
