An agricultural implement (10) including a frame (14), at least one rake (20) moveably coupled to the frame (14) and including a plurality of tine arms (28), a plurality of tines (30) connected to the plurality of tine arms (28), and a rotor drive (32) configured for rotating the plurality of tine arms (28), and an adjustment system configured for adjusting a rake height (H) of the at least one rake (20). The adjustment system includes at least one actuator (34), a controller (36) operably connected to the at least one actuator (34), and at least one dust sensor (38, 52, 54A, 54B) supported by the frame (14) and operably connected to the controller (36). The at least one dust sensor (38, 52, 54A, 54B) monitors a dust level and communicates dust level data to the controller (36) which correspondingly adjusts the rake height (H) based upon the dust level data.
