ABSTRACT:
A grooving depth indicator for a highway grooving or milling machine comprises a display device which is coupled by means of a cable to a mechanism which is employed to adjust the cutting depth of the machine. The display device includes an indicator scale which rotates relative to a zero marker, the scale being caused to rotate by a shaft on which a pulley is mounted. The coupling cable, which is maintained under tension by a spring bias, engages the pulley.
