摘要

A device suitable for use in agriculture. The device is provided with a rotatable tool (2,2',2'') and with electric current generating means (33) for generating electric current from the rotation of the rotatable tool (2,2',2''). The electric current generating means (33) are at least substantially disposed on the rotatable tool (2,2',2''). The device comprises electronics, such as sensors (21,23,27,37,38,39,42,43), said electronics being fed with electric current generated by the electric current generating means (33). The electronics, such as sensors, is disposed on the rotatable tool (2,2',2''). The device is preferably provided with a sensor (37) for measuring the number of revolutions per minute of the rotatable tool (2,2',2''). The electronics preferably comprises a transmitter (13)/receiver for transmitting signals. IMAGE
