| 摘要 |
The invention relates to a ground shaping machine, particularly an agricultural machine, comprising a frame (3), at least one roller (11) fitted with a flexible tire (13), a first bearing (37) and a second bearing (37) whereby the roller (11) can rotate about a substantially horizontal axis (XX) in the working position, the first bearing (37) and the second bearing (37) being positioned one at each end of the roller (11). The frame (3) has a first support (7) and a second support (9), the first support (7) at least being connected to the first bearing (37) through suspension means including a mechanism with an upper arm (101) and a lower arm (121), both substantially horizontal and perpendicular to the axis (XX) of rotation of the roller (4), each of the upper (101) and lower (121) arms being connected by a joint (103, 105, 123, 125) to the first support (7) on the one hand, and to the first bearing (37) on the other hand, the mechanism forming a deformable quadrilateral, while the suspension means also have a substantially vertical resilient return member (141) connected by a joint (143, 145) to the first support (7) on the one hand and to the first bearing (37) on the other hand.
