Dual blade implement system

An implement system for a machine (100, figure 1) working on a ground surface 106, the implement system featuring a primary blade 202; a secondary blade 210 coupled to the primary blade through a linkage mechanism 216 and where the secondary blade is trailing the primary blade. An actuator 244 is adapted to control a movement of the secondary blade and at least one position sensor 248, 250 generates signals indicative of a position of the primary blade and a position of the secondary blade. A controller 252 communicably coupled to the primary blade, the secondary blade and the position sensor, is configured to receive the signals indicative of the position of the primary blade and the position of the secondary blade and operate the actuator to control the movement of the secondary blade based on the position of the primary blade and secondary blade. In an alternative embodiment, a controller receives initial and final geometry of the ground surface and the primary and secondary blades are operated based on this geometry.
