Abstract

L'invention concerne un tracteur comportant un moteur 1 des roues motrices qui sont entraînées au moyen d'un convertisseur de couple ou variateur de vitesse hydraulique 3, un dispositif et des moyens de réglage pour adapter automatiquement le fonctionnement du tracteur à la charge produite par l'outil monté sur le tracteur. Le tracteur selon l'invention est remarquable en ce que les moyens de réglage commandent le rapport de transmission du convertisseur de couple en fonction du dérapage ou patinage au sol d'au moins une roue motrice.
