ABSTRACT OF THE DISCLOSURE: The present invention relates to a hydraulic- motor-driven two-unit cross-country vehicle, such as a forest tractor, consisting of tractive unit suspended on a bogie and provided with a dual hydraulic pump and with a drive engine for same, and of a load-carrying unit suspended on a bogie and coupled to the tractive unit. The pairs of wheels of both bogie components, both of the tractive unit and of the load unit, being driven each by a hydraulic motor of its own. Prior art vehicles of this type are provided either with a steering mechanism operating by means of steering clutches and brakes or with a steering mechanism operating by means of the articulated joint. A drawback of these steering systems is that they involve a certain slowness, which limits the manoeuvrability of the vehicle especially in difficult terrain, or that a great deal of the power output is missed during a steering manoeuvering because of the clutches and brakes. According to the present invention both of the driving hydraulic motors of the tractive unit are cross-connected with both of the driving hydraulic motors of the load unit so that the hydraulic motors cross-connected with each other are, during each steering operation, made to rotate their respective cross-connected pairs of wheels at the same speed of rotation as compared with each other, which results in that the vehicle has almost maximal power output on every wheel.
