Haymaking machine

A haymaking machine comprising:

• a frame;
• at least one turning or raking rotor which is arranged on the frame, the at least one turning or raking rotor being configured so that, in a working position, it is drivable relative to the frame about an axis of rotation in a direction of rotation of the at least one turning or raking rotor, the at least one turning or raking rotor comprising:
• at least two tine arms each of which comprise tines for turning or raking a crop, the at least two tine arms being aligned at least temporarily so as to face the ground,
• wherein,
• the at least two tine arms are arranged uniformly distributed in a circumferential direction around the axis of rotation of the at least one turning or raking rotor and are aligned in an approximately radial direction with respect to the axis of rotation of the at least one turning or raking rotor;
• a sensor which is arranged on the frame, the sensor being configured to continuously detect a passing of the at least two tine arms during an operation of the at least one turning or raking rotor and to transmit a measurement signal thereof;
• and
• a control device which is configured to receive the measurement signal transmitted by the sensor and, based thereon, to infer an operating state of the at least one turning or raking rotor.
