DIAZ ALVAREZ, Maximino Emiliano. Applications of the automatic control in the system of get up of three points of the tractor. Rev Cie Téc Agr [online]. 2013, vol.22, n.2, pp. 74-83. ISSN 2071-0054.

The work has the objective of basing the advantages that present the technological advances in the field of automatic controls and in particular in the three points hitch hydraulic system. It is made a description of the automatic system of position and their components, as well as a presentation of the different elements that come between the automatic regulations of the control points, by means of the employment of a system of electronic regulation for the one rises of implements with the three points hitch of the tractor. In this system they participate in combined form, several sensors that have the objective of measuring the main parameters that are regulated such as the control of the skadding and they register in the cabin of the tractor. Finally the handling of the electronic elevator is described and the definition of the operation of their components The conclusions express the importance, advantages and actuality that have these systems to improve the precision in the work and the conditions of comfort of the operator.
