<p>The combination has a wheel (68) driven by a drive i.e. hydraulic drive, or a roller, where the drive is torque controlled. The driving operation takes place by a tractive unit of a mobile working machine i.e. tractor. The hydraulic drive includes a variable displacement pump and a hydro-motor i.e. radial piston motor. The torque can be adjusted manually or by using an operator. The torque can be controlled in an automatic manner. A free wheel (66) is provided between the hydro-motor and the driven wheel or the roller. The saddle equipment is formed of a saddle plough, or a cart plough or a combination of ploughs.</p> |
