A hub-bearing assembly is used for mounting a soil cultivating disc (D) with an opportunity for rotation on a supporting axle (A) of an agricultural machine. The assembly comprises a hub-bearing unit (10) and a sealing device (20). The hub-bearing unit has a radially external rotatable outer race (11), from one side of which a flange (12) radially extends for mounting the disc (D). The sealing device (20) is mounted on a side of the hub-bearing unit, opposite to the side of the flange (12). The radially external surface of the assembly has a portion (38) located between the flange (12) and the side of the sealing device (20), which is radially deepened so as to serve as a preferential seat for winding wires picked up from the fields during the use of the agricultural machine. |
