<p>IMPROVED CENTERSHIFT LINKAGE MEANS FOR MOTOR GRADERS A powered vehicle has a longitudinally-extending main frame. A circle drawbar is mounted below the frame and a circle member is mounted below the drawbar and carries a blade. First hydraulic cylinder means is rotatably mounted at a first end thereof adjacent said frame and at a second end thereof adjacent a periphery of said circle drawbar, and second hydraulic cylinder means is rotatably mounted adjacent a first end thereof adjacent the periphery of said drawbar and adjacent a second end thereof adjacent said frame. A replaceable link is attachable in line with the first cylinder means to extend the length thereof, and the link is removable to allow the blade to be rotated beneath the frame from a first side of the motor grader to a second side thereof. This allows operation of said motor grader at a reduced bank cut angle of the blade to a surface being graded.</p> |
