Abstract
The harvesting machine includes an attachment, a feed device for material to be harvested, a cutting drum for the material to be harvested, an ejection means for conveying the material from the cutting drum, an advantageously hydrostatic drive for the feed device, a drive for the cutting drum, respective rotation speed sensors for measuring actual rotation speeds of the cutting drum and the feed device and an electronic analysis unit. To guarantee a constant cutting length of the harvested material or crop, the actual rotation speeds of the feed device and cutting drum are measured, an actual rotation speed ratio of the actual measured rotation speeds of the feed device and the cutting drum is computed in the electronic data analysis unit, a difference between a set rotation speed ratio characteristic of the cutting length and the actual rotation speed ratio is computed in the electronic analysis unit and the analysis unit generates a control signal according to this difference for controlling the hydrostatic drive of the feed device. Furthermore a process of monitoring and controlling the feed of material to be harvested into the harvesting machine is described.
