The invention relates to an agricultural machine and to a bearing arrangement comprising a support body (2) which is rotatably supported on a support frame (4) via rolling bearings (13) and comprising tools (3) which are arranged on the support body (2) adjacently to one another in the axial direction and which can be rolled on the ground. Bearing housings (7) of the rolling bearings (13) are fixed to support body walls (9) which are provided substantially at the ends of the support body (2), and each rolling bearing is connected to a support arm of the support body (2) via a bearing pin (13). The aim of the invention is to provide an agricultural ground roller which can be produced with less manufacture and production expenditure while maintaining a high degree of dimensional accuracy between the bearing pin (12) and the rolling bearing (13). This is achieved in that the rolling bearing (13) is removably fixed to a support body wall (9) via the bearing housing (7), the bearing pin (12) is removably fixed to the corresponding support arm (15), and the bearing pin (12) is connected to the support body wall (9) via the rolling bearing (13) and the bearing housing (7).
