Blade attachment for motor grader

Abstract

A wing blade attachment for a motor grader used to maintain unimproved rural roads. The wing blade attachment mounts to a trailing end of a main motor grader blade and swings up and down into ground scraping contact in order to create water drainage passages through the gravel windrows along the road edges or to smooth roadways at intersections, bridges and driveways. The windrows are placed by road maintenance crews to stockpile materials for roadway use. A linear actuator such as a hydraulic ram allows the grader operator to remotely and selectively swing the wing blade up and down and cut passages.

         10 . An attachment blade assembly for use with a motor grader to create drainage passages through a roadway windrow, the attachment blade assembly comprising a short wing blade for attachment to a substantially longer motor grader blade and a remotely actuated linear actuator and a pivotally mounted angled arm, the actuator acting upon said angled arm through a linkage mechanism to selectively position said wing blade in a downward scraping position in a forwardly angled vee relationship with said motor grader blade and raise said wing blade to a bypass position swung upwardly to a forwardly veed position, and swing said wing blade to a fully stowed position parallely concealed and protected behind said motor grader blade, thereby permitting a motor grader operator to perform multiple functions without removal of said attachment blade.
