Abstract

L'invention concerne un véhicule quadricycle enjambeur automoteur comportant un châssis (2) équipé à l'avant, d'un demi-train de roulement directeur avant gauche et d'un demi-train de roulement directeur avant droit, le châssis étant pourvu à l'arrière, d'une jambe de support (5) d'un demi-train de roulement arrière gauche (6) et d'une jambe de support (7) d'un demi-train de roulement arrière droit (8), les jambes de support (5, 7) étant écartées en position de travail, de manière que les demi-trains de roulement arrière délimitent entre eux une largeur de voie telle que chaque jambe de support délimite avec le châssis (2), un passage (P) pour un rang de culture (R). Selon l'invention, les demi-trains de roulement avant sont montés pour délimiter entre-eux une largeur de voie fixe (L2) comprise entre 0,5 et 1 m, adaptée afin que les demi-trains de roulement avant puissent rouler dans un même espace inter-rang (E).The invention relates to a self-propelled straddle quadricycle vehicle comprising a frame (2) equipped at the front, with a front left steering half-undercarriage and a front right-hand steering half-undercarriage, the chassis being provided with the rear, a support leg (5) of a left rear half undercarriage (6) and a support leg (7) of a right rear half undercarriage (8), the support legs (5, 7) being spaced apart in the working position, so that the rear half-undercarriages define between them a track width such that each support leg defines with the frame (2), a passage ( P) for a crop row (R). According to the invention, the front half-undercarriages are mounted to define between them a fixed track width (L2) of between 0.5 and 1 m, adapted so that the front half-undercarriages can run in a same inter-row space (E).
