  • Automatic control device for tying in a hay baler
    Patent number: 4624179
    Abstract: An automatic control device for tying large diameter cylindrical bales produced by a hay baler. A tie guiding arm has an end which can be driven back and forth over the entire width of the bale by an electric motor. A microprocessor receives inputs indicating the driving speed of the baler, the diameter of the bale and the desired number of turns of the tie. The motor driving the guiding arm is discontinuously driven by the microprocessor so that the arm is held in a stationary position for a predetermined length of time at a predetermined number of stops. The microprocessor may also operate in a learning mode where the operator sets the number of stops and the length of time.
