System for controlling earthworking implement

Abstract

A system for controlling an earthworking implement having a plurality of orientations is provided. The earthworking implement is operable in a plurality of orientations. The earthworking implement is removably attached to a track-type tractor that includes a blade support member. The system includes four independently operable hydraulic cylinders where one end of each hydraulic cylinder is pivotally attached to the earthworking implement and other end attached to the blade support member. Further, each of the hydraulic cylinders is adapted to control the orientations of the earthworking implement with respect to the blade support member. A blade support member includes a first end and a second end. Further, the first end is pivotally attached to a center portion of the earthworking implement, and the second end is attached to the main frame.

1 . A system for controlling an earthworking implement operable in a plurality of orientations, the earthworking implement removably attached to a track-type tractor having a main frame , the system comprising:
 a blade support member comprising a first end and a second end, wherein the first end is pivotally attached to a center portion of the earthworking implement, and the second end is rigidly attached to the main frame, and   four independently operable hydraulic cylinders, one end of each hydraulic cylinder pivotally attached to the earthworking implement and other end attached to the blade support member wherein each of the hydraulic cylinders are adapted to control orientations of the earthworking implement with respect to the blade support member.
