An earth compactor is propelled by a hydraulic circuit that includes a first hydraulic motor (36) to drive a drum member (15) and a second hydraulic motor (32) to drive a tractor member mounted on tires (7), with a traction control system that includes a motor speed sensing device (44, 46) on each hydraulic motor (36, 32). The speed sensing devices (44, 46) transmit electrical signals to a microcontroller (42), which compares the speeds and varies the speed of the tires (7) or drum (15) to maintain a preselected ratio between the two, thereby maintaining traction of both members.
Compacteur de sol propulsé par un circuit hydraulique composé d'un premier moteur hydraulique (36) entraînant un tambour (15) et d'un second circuit hydraulique (32) entraînant un élément tracteur monté sur pneus (7), avec un système de gestion de la traction comprenant un dispositif capteur (44, 46) de la vitesse du moteur sur chaque moteur hydraulique (36, 32). Les capteurs de vitesse (44, 46) transmettent des signaux électriques à un microrégulateur (42) qui compare les vitesses et fait varier la vitesse des pneus (7) ou du tambour (15) pour conserver un rapport prédéfini entre les deux, maintenant ainsi la traction des deux éléments.
