The present invention relates to a frame (1) for soil working tools (27) comprising a central boom (10) a frame body (10 ') integral with an end of said boom (10), and at least one section lateral rear member (11) integral with said frame body (10 ') and carrying tools (27), said frame body (10') resting on main bearing wheels (12) and said at least one lateral rear section (11) resting on at least one secondary carrier wheel (16) said frame (1) being able to assume an operating state in which said at least one lateral rear section (11) is deployed relative to said boom (10) and away from the ground so the tools (27) are not engaged with the ground. According to the invention, in said operating state, said at least one secondary carrier wheel (16) can take at least: a position of displacement substantially in a straight line of said chassis (1) and a gyration position in which the absolute value of the distance (D) between it and a plane (P) substantially orthogonal to the ground (S) and passing through the axis of rotation (Δ) of said main bearing wheels (12)； ) is lower than in said substantially straight-line displacement position of the frame (1).La présente invention concerne un châssis (1) porte outils de travail du sol (27) comprenant une flèche centrale (10) un corps de châssis (10') solidaire d'une extrémité de ladite flèche (10), et au moins un tronçon arrière latéral (11) solidaire dudit corps de châssis (10') et portant des outils (27), ledit corps de châssis (10') reposant sur des roues porteuses principales (12) et ledit au moins un tronçon arrière latéral (11) reposant sur au moins une roue porteuse secondaire (16) ledit châssis (1) pouvant prendre un état de manoeuvre dans lequel ledit au moins un tronçon arrière latéral (11) est déployé par rapport à ladite flèche (10) et éloigné du sol de sorte que les outils (27) ne soient pas en prise avec le sol. Selon l'invention, dans ledit état de manoeuvre, ladite au moins une roue porteuse secondaire (16) p
