Mistie Detector and Indicator System Abstract of the Disclosure A knotter mechanism, utilized on a square baler to encircle the bale with a wrapping material and tie a knot in the material after the wrap is complete, is provided with a detector mechanism for detecting knotter malfunction. The detector mechanism comprises an elongated detector pin which is mounted to pivot in a vertical plane, the pin being mounted on the twine finger of the knotter mechanism 80 as to pivot therewith in a horizontal plane. The pin is encircled by the wrapping material as the bale is encircled and is within the loop of wrapping material after a knot is tied. As the tied bale is moved rearwardly from the knotter station the detector pin engages the loop of wrapping material and pivots the twine finger thus causing a switch to be actuated. Failure to actuate a switch signals a knotter failure, Upon further movement of the tied bale rearwardly, the loop of wrap material slips over the end of the detector pin and a spring mechanism returns the twine finger and the pin to their initial position.
