Abstract

L'invention concerne un véhicule auxiliaire agricole (10) non entraîné pourvu d'au moins deux mécanismes de roulement à courroie parallèles, disposés sur les côtés longitudinaux opposés d'une surface ou d'une plateforme ou de roues porteuses disposées de part et d'autre de la plateforme. La plateforme sert de logement de support de charge d'une remorque (40). Le véhicule auxiliaire (10) est relié en cas d'utilisation, à un véhicule tracteur agricole (60) lors d'un passage dans un champ sur les surfaces de contact au sol, bloquées sur la surface ou la plateforme, des roues de la remorque (40) et de la flèche d'attelage (46) de ladite remorque ou un autre élément d'accouplement. L'invention concerne en outre un procédé permettant de faire fonctionner des transports de charges agricoles sur des trajets de conduite et/ou de transport, lesquels comportent des sections de transport sur des terres assolées non stabilisées et/ou sur un sol stabilisé, en particulier sur des routes ou des chemins. Selon ce procédé, une remorque (40) tirée par un véhicule tracteur agricole (60), pour se préparer au passage d'un champ sur des terres assolées non stabilisées, est transférée sur le véhicule auxiliaire (10). Enfin, l'invention concerne un ensemble de traction, lequel comporte un véhicule tracteur agricole (60) et une remorque (40) attelée par l'arrière ou par l'avant audit véhicule tracteur. La remorque (40) repose sur la plateforme du véhicule auxiliaire (10) non entraîné au moyen d'au moins deux mécanismes de roulement à courroie ou au moyen de roues porteuses sur pneus, et est reliée par sa flèche d'attelage (46) au véhicule tracteur agricole (60).
