Abstract: The invention relates to a separating device (3) and to a separating method for separating weed seeds and lost crops from the wastage outflow (102) of a harvesting machine (1). The separating device (3) is arranged on the harvesting machine (1) to the outlet area for the wastage (2) of the harvesting machine (1) and has at least one rotating separating element (31), with which a material stream substantially consisting of weed seeds and lost crops is separated from the wastage outflow (102) of the harvesting machine (1). The remaining material stream (103) substantially consists of non-grain constituents and can be spread back directly onto the field, while the separated material stream substantially consisting of weed seeds and lost crops can first be collected and e.g. rendered unable to germinate.

Abstract: A method for monitoring the functioning of an electric motor-driven pump (1), preferably in a vehicle (F), which has an internal electronics system (4) by means of which functional parameters of the pump (1) are monitored. The internal electronic system (4) relays the values of the functional parameters to a central control device (8) via an internal communication interface (6), and the values of the functional parameters are detected and monitored in the central control device (8) with respect to critical limiting values. The change over time of at least one value of the functional parameters is detected in the central control device (8), and a malfunction of the pump (1) is deduced if a value of at least one functional parameter remains constant over a predefined period of time.
