Abstract

Tracteur agricole caractérisé en ce qu'il comprend une boîte de différentiel contenant un mécanisme de différentiel, une boîte de transmission contenant un mécanisme de changement de vitesses, une boîte de changement de vitesses se montant entre la boîte de différentiel et la boîte de transmission, de manière à être directement accouplée à celles-ci, et un mécanisme de changement de vitesses contenu dans la boîte de changement de vitesses et destiné à fournir un rapport de réduction plus grand que le rapport de réduction maximal du mécanisme A. L'invention s'applique aux tracteurs agricoles mixtes à vitesses normales et vitesses très lentes.
