Reconfigurable grading blade attachment with a stabilizer wheel assembly on a work machine

A work machine with a reconfigurable grading blade attachment, the work machine comprising of:

• a frame supported by a plurality of ground-engaging units, the ground-engaging units configured to support the frame on a surface;
• a boom assembly coupled to the frame, the boom assembly having a pair of boom arms pivotally coupled to the frame and movable relative to the frame by a pair of boom hydraulic actuators;
• an attachment coupler coupled to a distal portion of the pair of boom arms, the attachment coupler movable relative to the frame by a pair of attachment pitch hydraulic actuators;
• a grading blade coupled to the attachment coupler, the grading blade extending transversely to a frame length;
• an attachment frame including an upper attachment frame portion and a rear attachment frame portion, the upper attachment frame portion having a frame length extending forward from the rear attachment frame portion;
• a pivot beam extending transversely to the attachment frame length and pivotally coupled to the upper attachment frame portion such that the pivot beam is pivotable about a pivot beam axis relative to the upper attachment frame portion, the pivot beam having a left portion and a right portion on opposite sides of the pivot beam axis;
• a left stabilizer wheel assembly pivotally coupled to the left portion of the pivot beam such that the left stabilizer wheel assembly is pivotable about a left wheel lift axis;
• a right stabilizer wheel pivotally coupled to the right portion of the pivot beam such that the right stabilizer wheel assembly is pivotable about a right wheel lift axis;
• a center mount positioned vertically from the pivot beam;
• a left hydraulic actuator coupled to the center mount on a first end and coupled to the left stabilizer wheel assembly on a second end, wherein retraction of the left hydraulic actuator rotates the left stabilizer wheel assembly upwards about the left wheel lift axis;
• a right hydraulic actuator coupled to the center mount on a third end and pivotally coupled to the right stabilizer wheel assembly on a fourth end, wherein retraction of the right hydraulic actuator rotates the right stabilizer wheel assembly upwards about the right wheel lift axis;
• a positioning unit configured to at least raise or lower the stabilizer wheel assemblies via the left hydraulic actuators and the right hydraulic actuator;
• a hydraulic circuit communicatively coupled to a controller, the hydraulic circuit including
• a hydraulic pump coupled to the left hydraulic actuator and the right hydraulic actuator, the hydraulic pump delivering fluid through a plurality of flow paths, the plurality of flow paths coupled the left hydraulic actuator, the right hydraulic actuator, and at least one proportional valve;
• and
• the controller functionally linked to the positioning unit, and configured to selectively adjust the at least one proportional valve as a function of input signal corresponding to a desired grading blade attachment configuration to be generated by the left hydraulic actuators and the right hydraulic actuators to position the left stabilizer wheel assembly and the right stabilizer wheel assembly with respect to the ground surface;
• the controller automatically controlling the at least one proportional valve to achieve the desired grading blade attachment configuration.
