N2  - This research aims to utilize, study and evaluate some engineering parameters, which affect the mechanical performance of the helical mower during the cutting operation of maize stems. These parameters were; knife edge angle «1). diameter and length of helical knife (d), cutting speed (N) and distance between fingers (lo). These parameters and their effects on the mechanical performance of the helical mower were assessed using four criterions during the cutting operation. The obtained data of the experimental work revealed that the previous parameters strongly affect the mechanical efficiency of cutting operation. They also showed that the conventional edge angle, cutting rotary speed, distance between fingers and diameter and length of helix which achieve the best cutting of maize stems rang between; 21-24°, 1000-1200 rpm, 80-120 mm and 180-200 mm respectively
