  • WING PLOW WITH ROTATABLE FLOATING CONNECTION
    Publication number: 20160273176
    Abstract: A wing plow assembly includes a mast including a support frame adapted for mounting to a chassis, a moldboard having a toe end and a heel end, and a moldboard connector assembly arranged with the moldboard and the mast to provide a rotatable floating connection between the moldboard and the mast such that the moldboard is rotatably movable over a range of travel between a plowing position and a range of tripped positions. The moldboard connector assembly includes a link arm pivotably mounted with respect to the support frame and a moldboard mount pivotably mounted to the moldboard adjacent the toe end of the moldboard. The link arm and the moldboard mount are pivotably connected to each other to permit relative rotation therebetween. The moldboard can pivot from a plowing position to a tripped position when a cutting edge of the moldboard strikes an obstruction.
