Agricultural vehicle e.g. combine harvester, has harvester head elastically deflected against pressure, compressed gas supplies connected by compressed gas pipe, and check valve arranged in gas pipe and controlled by magnetic coil
The vehicle e.g. combine harvester (1), has a harvester head (2) elastically deflected against pressure of a compressed gas supply based on a ground driven by the vehicle. An oil pump and a control valve are provided for changing volume of another compressed gas supply. The gas supplies are connected by a compressed gas pipe, and a check valve i.e. non-return valve, is arranged in the pipe. The gas supplies are arranged in respective pressure containers, where the check valve is controlled by a magnetic coil. A pressure sensor is arranged between the check valve and a compressed gas chamber. An independent claim is also included for a method for adjusting a vehicle.
