Combine KOP-1.4 is aggregated with tractors of class 3. The working bodies are driven from the tractor PTO shaft. The distance between the center lines of the heder bed is 80 cm, therefore, the combine harvesters two rows of maize sown with row spacing of 70 or 90 cm. The working speed is from 3.5 to 8 km / h.
