Significant difference (p < 0.05) was observed for the actual velocity (Table 1), which is caused by the different gear selection performed in each treatment. At the actual velocity of 5.01 km h-1, the tractor used a gear of lower velocity and higher power (L3), compared with the L4 gear, used at the other actual velocity (6.92 km h-1). The values were close to the respective theoretical velocities and statistically different, which shows that there is a difference between the velocity treatments. As to the working depths, there was no significant difference, i.e., the working depth of the shank did not interfere with the final velocity of the set, whose behavior may have been due to the fact that soil resistance in subsurface was not enough to affect the velocity of the set. Silveira et al. (2005), working with two velocities, 5.24 and 7.09 km h-1, at two seed deposition depths, also observed significant difference between the actual velocities; furthermore, the velocities did not differ statistically at the depths. Thus, these authors concluded that the depth did not interfere with the velocity of the set in the sowing operation.
