Abstract: A ground shaping machine, particularly an agricultural machine, including a frame, at least one roller fitted with a flexible tire, a first bearing and a second bearing whereby the roller can rotate about a substantially horizontal axis in the working position, the first bearing and the second bearing being positioned one at each end of the roller. The frame has a first support and a second support, the first support at least being connected to the first bearing through a suspension device including a mechanism with an upper arm and a lower arm, both substantially horizontal and perpendicular to the axis of rotation of the roller, each of the upper and lower arms being connected by a joint to the first support, and to the first bearing, the mechanism forming a deformable quadrilateral, while the suspension device also have a substantially vertical resilient return member connected by a joint to the first support and to the first bearing.
