Implement mounting arrangement with independent lift-roll and pitch-yaw

Abstract

An implement mounting arrangement for a work machine providing simplified, independent lift-roll and pitch-yaw operability. The present arrangement includes at least one push arm connected to the work machine for rotation about a horizontal lift axis; an implement support frame mounted to the at least one push arm for rotation about a roll axis and including a lift arm extending cross-wise to the roll axis, the lift arm including a first terminal end and an opposite second terminal end located respectively on opposite sides of the roll axis in spaced relation thereto; an implement mounted to the implement support frame for rotation about a pitch axis and about a yaw axis; a pair of lift-roll cylinders operably connected between the work machine and the respective terminal ends of the lift arm; and a pair of pitch-yaw cylinders operably connected between the implement and the respective terminal ends of the lift arm; wherein the lift-roll cylinders are operable to rotate the support frame and the implement about the lift axis and about the roll axis relative to the work machine independently of the pitch-yaw cylinders, and the pitch-yaw cylinders are operable to rotate the implement about the pitch axis and about the yaw axis relative to the implement support frame independently of the lift-roll cylinders.
