A grading implement features a frame with at least one movable section carried by a main frame section. Each movable section is movable relative thereto between a storage position and a working position reaching further laterally outward from the main section to increase a working width of the implement. An underside of each movable section features a respective blade adjustably mounted thereto for selective adjustment between different relative blade positions relative to the movable section. One embodiment features outboard blades on two movable sections, inboard blades on another two movable sections, and a rear blade mounted centrally on the main section behind the inboard and outboard blades. A dust suppression system features spray nozzles distributed across the main frame section behind the blades, and storage tanks mounted atop the main section so that weight of the dust suppression agent provides extra downforce to the blades.
