CA 2390843

A field marker apparatus comprises a marker arm adapted for attachment at an inner end thereof to an agricultural implement such that the marker arm extends laterally from the implement as the implement moves in an operating travel direction, and an outer end of the marker arm is supported by a rotatable disc adapted to engage the ground to make a furrow substantially parallel to the operating travel direction. The disc is pivotally mounted to the apparatus such that an operating angle between the disc and the operating travel direction can pivot from a most aggressive operating angle to a least aggressive operating angle. A bias element is operative to exert a bias force on the disc that causes the disc to pivot towards the most aggressive operating angle.
