A method for determining the sharpness of cutting edges () of chopper blades () at a rotationally driven chopper drum () of a forage harvester includes scanning a blade surface of at least one of the chopper blades located behind the cutting edge by at least one electrode operating as a contact sensor and determining a duration of contact of the at least one electrode with the blade surface.

Method for determining the sharpness of cutting edges of chopper blades

A harvesting device for harvesting and/or picking up crop such as plants or plant parts located on the field is configured with a pick-up unit with a working width oriented transversely to the direction of travel (F), for picking up the crop. The pick-up unit has a multiplicity of pick-up elements, each of which can move at least partially in the vertical direction and are disposed along the working width. Outer ends of the movable pick-up elements form envelope curves during operation. A conveyor unit for further conveying the picked-up crop is provided downstream of the pick-up unit in the direction of the crop flow. The harvesting device so arranged improves the pick-up or intake of crop because the conveyor unit at least partially overhangs the envelope curves of the pick-up elements in the direction of travel (F).
