The invention relates to a vibration isolation device for agricultural machines comprising at least one roller coupled to the machine by means of a supporting structure to which the roller is secured at the ends thereof. The device can be used as a means for isolating the vibration produced as the roller is pulled along the ground. The device comprises multiple rubber isolating elements secured at each of the ends of the roller with variable inclination, said elements being distributed radially about the shaft such as to form a flexible link between the roller and the supporting structure.
