A hydraulic motor and centre wheel group, includes a hydraulic motor positioned in line with a centre wheel and connected to the centre wheel in rotation with the motor, and couplings for a mechanical reaction mechanism rotation connected between the hydraulic motor and a support organ or frame for the group. At least one inner race per corresponding crown of rolling bodies of a rolling friction bearing is formed on an outer diameter of a shell of the hydraulic motor. A diametral plane for loading the rolling friction bearing is positioned on a diametral plane characteristic of the hydraulic motor, and the hydraulic motor includes a radial cylinder including a diametral plane which includes the crown of rolling bodies in correspondence with the diametral plane for loading the rolling friction bearing |
