1. A round baler connectable to a tractor for providing round bales, the baler comprising:
a baling chamber, configured for receiving crops and forming a bale;
a frame, at least partially delimiting the baling chamber;
a drive shaft, connectable to the tractor and configured to receive mechanical power from the tractor;
a transmission system, for receiving mechanical power from the drive shaft and for imparting a rotating movement to the crops contained in the baling chamber, the transmission system including a drive roller connected to the frame, a chain assembly connected to the drive roller, and an oil circuit, containing lubricant oil for the chain assembly;
a control unit; and
a sensor, associated with the transmission system for detecting a diagnostic parameter representative of a working condition of the transmission system, wherein the control unit is connected to the sensor to receive the diagnostic parameter and is programmed for processing the diagnostic parameter to generate a feedback signal for a user of the round baler,
wherein the control unit has access to a memory containing a threshold value for said diagnostic parameter, and wherein the control unit is programmed for generating the feedback signal responsive to a comparison between the value of the diagnostic parameter and the threshold value stored in the memory,
wherein the baler comprises an additional sensor, coupled to the transmission system and configured to detect an additional diagnostic parameter, wherein the control unit is programmed for processing the additional diagnostic parameter and for generating the feedback signal responsive to both the diagnostic parameter and the additional diagnostic parameter, and
wherein the control unit is programmed to carry out in real time a comparison between values of the diagnostic parameter and of the additional diagnostic parameter, and to generate the feedback signal responsive to said comparison, wherein the diagnostic parameter and the additional diagnostic parameter are representative of a same physical entity, detected at two different locations of the baler.
