Abstract

A combine harvester has at least one header for cutting plants to be harvested with the aid of the combine harvester, a feeder for conveying the cut plants in the direction of a threshing mechanism, and a threshing mechanism, with the aid of which fruits can be removed from the cut plants in such a way that the fruits are then present separately from plant residue of the plants. The feeder comprises a revolvingly driveable conveying unit and a conveyor channel within which the cut plants can be conveyed with the conveying unit. The feeder interacts with a measuring unit in the form of a sensor unit that contactlessly detects material feed height of plants conveyed with the aid of the feeder in the conveyor channel.
