Summary:The invention concerns a device for ground copying for front attachments to harvesting machines, especially for self-propelled combine harvesters and forage choppers, in accordance with the features in the generic terms of claim . A crop harvesting machine is provided having a crop feeder device that is movable through various heights via manipulation of first hydraulic cylinders. A crop gathering attachment is mounted onto a front side of the crop feeder device. A crop gathering attachment is provided having fixed height sensors that measure a distance of the attachment above the ground. A second hydraulic cylinder is provided between the crop feeder device and the crop gathering attachment to control the angle of tilt of the crop gathering attachment relative to the crop feeder device. The angle of tilt is measured by a tilt sensor. A controller is connected to the sensors and provides output to the cylinders to control the machine height and angle of tilt.
