Method of controlling a grading attachment on a skid steer vehicle

A method of controlling a grading attachment on a skid steer vehicle comprising the steps of:

• providing a skid steer vehicle with a main arm rotatably coupled a stationary frame structure of the skid steer body with at least one of an arm electric non-hydraulic cylinder and an arm drive motor and coupled to a grading attachment with at least one of a pitch arm electric non-hydraulic cylinder and a pitch drive motor operably configured to adjust a pitch axis movement of the grading attachment independent of movement of the main arm, wherein the at least one of the pitch electric non-hydraulic cylinder and the pitch drive motor with a portion coupled to the main arm and another portion coupled to a frame element rotatably coupled to the main arm;
• lowering the main arm with the at least one of the arm electric non-hydraulic cylinder and the arm drive motor to its lowest allowed position along an arm translation path;
• and
• adjusting, while the main arm is maintained in its lowest allowed position, while grading in the skid steer vehicle, and with the at least one of the pitch arm electric non-hydraulic cylinder and the pitch drive motor, the pitch axis movement of the grading attachment autonomously using an automatic grade control system, wherein the automatic grade control system is communicatively coupled to the at least one of the arm electric non-hydraulic cylinder and the at least one of the pitch arm electric non-hydraulic cylinder and the pitch drive motor.
