Abstract

The use of agricultural mechanization has become more efficient in several agricultural practices, highlighting the tractor as the main machine used in carrying out these activities, thus allowing more efficient cultivation practices. The objective was to determine the field length that obtains field efficiency of 90% in the soil tillage operation with a medium harrow depending on the displacement speed and the length of the field. The experiment was carried out in a completely randomized design, in an 8x3 factorial scheme, with six replications, totaling 96 observations. The first factor was eight field lengths (30, 60, 90, 120, 150, 180, 210 and 240 m). The second was three travel speeds (3.0; 4.1 and 4.7 km h-1). With the effective field yield data, a response curve was generated to select the field length that provides an effective field yield of 90%. In the displacement speed factor, the greatest operational field capacity occurred with 4.7 km h-1. For the field length factor, the greatest operational field capacity and field yield effective was observed with 240 m. The effective field yield of 90% is achieved with a field length of 120 meters. Maximum field capacity occurred at a speed of 4.7 km h-1 (0.93 ha h-1) with a field length of 214 m.
