The machine has a roller (11A) fitted with a flexible tire (13A), where bearings (37) are positioned at ends of the roller. A support (7A) of a frame is connected to one of the bearings through a suspension unit including a mechanism with an upper arm and a lower arm (121). The arms are horizontal and perpendicular to a rotation axis (XX) of the roller. Each arm is connected to the support and the bearing by a joint. The mechanism forms a deformable quadrilateral, and a vertical resilient return element (141) is connected to the support and the bearing by another joint. The resilient return element is a pneumatic or hydraulic jack. |
