A bulldozer blade mounting structure is disclosed. The mounting structure includes a first pivot arm having a first end adapted for pivotal attachment to a tractor and a second end coupled to a bulldozer blade, and a second pivot arm having a first end adapted for pivotal attachment to a tractor and a second end coupled to a bulldozer blade. The mounting structure also includes a first coupling joint coupling the second end of the first pivot arm to the bulldozer blade, wherein the first coupling joint permits the bulldozer blade to rotate about a longitudinal axis of the first pivot arm and to rotate about an axis substantially perpendicular to the longitudinal axis of the first pivot arm. The mounting structure is also provided with a second coupling joint coupling the second end of the first pivot arm to the bulldozer blade, wherein the second coupling joint permits the bulldozer blade to rotate about a longitudinal axis of the second pivot arm and to rotate about an axis substantially perpendicular to the longitudinal axis of the second pivot arm. The mounting structure is further provided with a first actuator having a first end adapted for attachment to a tractor and a second end pivotally secured to the first coupling joint, and a second actuator having a first end adapted for attachment to a tractor and a second end pivotally secured to the second coupling joint.
