ABSTRACT:
A telescoping field marker which is retractable into a compact storage position. The inventive device includes a bracket structure attachable to an implement frame, an inner arm having a lumen pivotally attached to the bracket structure, a hydraulic cylinder attached between said bracket structure and said inner arm, a hydraulic motor within the inner arm adjacent the bracket structure, an outer arm slidably positioned within the lumen of the inner arm, and a threaded shaft connected to the hydraulic motor and threadably connected to a proximal end of the outer arm for extending and retracting the outer arm with respect to the inner arm. A marking disc is attached to a distal end of the outer arm for marking a ground surface. The outer arm is free to move upwardly and downwardly when fully extended thereby compensating for uneven terrain. The hydraulic cylinder and the hydraulic motor are preferably fluidly connected in series so as to operate simultaneously.
