Road grader implement with storable and deployable blade
First Claim
1. A grading implement comprising:
- a frame comprising;
a main section having a longitudinal direction in which the frame is arranged to be conveyed over a road surface;
at least one movable section carried by the main section and movable relative thereto between a storage position and a working position, said at least one movable section reaching further laterally outward from said main section in the working position than in the storage position; and
a blade arrangement comprising;
at an underside of each movable section that faces downwardly toward the road surface in at least the deployed working position, a respective outboard blade carried by the respective movable section for working engagement of said blade with said road surface, said outboard blade being adjustably mounted to the respective movable section for selective adjustment between different relative blade positions relative to said movable section; and
at least one inboard blade each mounted to the main section of the frame a position that is situated more inboard of the main frame section than each outboard blades each movable sections is deployed in the working position;
wherein the respective outboard blade of each movable section of the frame is mounted thereto entirely separately and independently of each inboard blade mounted to the main section of the frame.

Abstract
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.
