(FR) CHARRUE A CORPS SYMETRIQUE A ANGLE D'ATTAQUE VARIABLE REGLABLE ET A LARGEUR DE TRAVAIL VARIABLE
Abstract
(EN)
A plough comprises at least one symmetrical body with ploughboard (40) and ploughshare (41), unique for the two directions of ploughing and provided with a guide means for each of them. The body is mounted on a body support (17). The assembly pivots by an articulated means about a vertical axis (18) of a body support beam (9) the end of which moves in two left and right half-rails (12) belonging to the head (3), which rotates about the drawbar shaft (1). Between them, the half-rails define, toward the longitudinal axis, a circular part which also comprises means (34) for blocking the oscillation of the head (3) on the drawbar shaft. A single guiding means for the two directions of ploughing for one or all the bodies consists of a blade articulated (28) about a vertical axis (25).
