A folding frame farm implement comprising: a) a cart (21), b) a multi-section rockshaft frame (20) mounted on said cart and oriented generally transversely in the working position, c) said rockshaft frame (20) having a central section (20c) and laterally disposed wing sections (20a, 20e), d) wheel means (2, 3) supporting said rockshaft frame sections, e) said rockshaft frame sections being rotatable about a generally transverse axis between a lst position and a 2nd position, f) a plurality of individual tool frame sections (27, 28) rotatably mounted to corresponding ones of said rockshaft frame sections about a generally transverse axis, g) individual wheel support means (29, 31) for each tool frame section, h) wherein said tool frame sections (27, 28) are supported at working positions and a non-working position at a variable height above the ground determined by the relative rotational position of the rockshaft frame (20) between said lst position and said 2nd position and by the said wheel support means (29, 31), i) central tool frame section support means (31) associated with said central rockshaft frame section adapted to retain said central tool frame section (20c) in close proximity to the ground for transport, j) lift means to further rotate said wring frame tool sections (20a, 20c) from a generally horizontal position to a raised position for transport and k) said wing sections (20a, 20c) being foldable rearwardly for transport.

L'invention concerne une machine agricole à châssis pliant, qui comprend a) un chariot (21); b) un châssis (20) axe oscillant constitué de plusieurs éléments, monté sur ledit chariot et orienté de manière généralement transversale quand il est dans la position de travail; c) ledit châssis (20) axe oscillant comprend un élément central (20c) et des éléments ailerons latéraux (20a, 20e); d) un dispositif roues (2, 3) supportant lesdits éléments du châssis axe oscillant; e) lesdits éléments du châssis axe oscillant peuvent tourner autour d'un axe généralement transversal entre une première et une seconde position; f) une pluralité d'éléments de châssis outils (27, 28) distincts, montés rotatifs sur l'élément de châssis axe oscillant correspondant autour d'un axe généralement transversal; g) un dispositif support à roue, distinct pour chaque élément de châssis outil; h) lesdits éléments de châssis outils (27, 28) sont supportés, dans leurs positions de travail et de non-travail, à une hauteur variable au-dessus du sol, déterminée par la rotation relative du châssis (20) axe oscillant entre ladite première position et ladite seconde position et par le dispositif support à roue (29, 31); i) un dispositif support d'élément de châssis outil central (31), associé audit élément de châssis axe pivotant et conçu pour retenir ledit élément châssis outil central (20c) à proximité du sol pendant le transport; j) un dispositif de levage faisant tourner lesdits éléments outils de châssis ailerons (20a, 20c) depuis une position généralement horizontale à une position surélevée pendant le transport; et k) lesdits éléments ailerons (20a, 20c) peuvent se replier vers l'arrière pendant le transport.
