摘要

System of automatic correction level through the device controller of reaction forces to the leaks from the ideal position of the work of the spray booms self leveling.That is, fixed in the central framework (2) of the spray boom (1), a track (5) with variable height on the surface of contact with a pulley (6) so that the slide on the track, by the action of the spray boom (1), where the latter tend to leave the posi In parallel with the ground, causing, by the action of a tencionador adjustable element (7),A reaction force sufficient to maintain the spray boom (1) at the working position, even when the vehicle (tractor), tracionador suffers sudden unevenness when passing in hilly terrain or cross diagonally on the terraces of large base, in cultivation areas.In situations of extreme slopes, in which the system loses the ability of leveling, the system has a hydraulic actuator that allows the operator to complement the levelling of the spray boom (1) manually.
