Work machine with automatic pitch control of implement

A method for automatically adjusting a pitch of a blade on a work machine, comprising:

• providing the blade with a main portion, a wing portion pivotally coupled to the main portion, a first actuator, a second actuator, and a controller including a memory unit;
• determining by the controller if the wing portion is angled relative to the main portion;
• determining by the controller if the first actuator is being actuated to change an angle of the blade;
• if the wing portion is angled relative to the main portion and the first actuator is being actuated, determining a desired pitch of the blade by the controller;
• determining by the controller a position of the second actuator to achieve the desired pitch;
• and
• adjusting by the controller the position of the second actuator.

A work machine, comprising:

• a chassis;
• a cab mounted to the chassis;
• a blade coupled to the chassis, the blade comprising at least a main portion and a wing portion, the wing portion being pivotally coupled to the main portion;
• a first actuator coupled between the chassis and the blade, the first actuator being operably controlled to adjust an angle of the blade;
• a second actuator coupled between the chassis and the blade, the second actuator being operably controlled to adjust a pitch of the blade;
• a third actuator coupled between the chassis and the blade, the third actuator being operably controlled to adjust a tilt of the blade;
• a controller disposed in communication with the first actuator, the second actuator, and the third actuator, the controller operably controlling each actuator based on user inputs and control logic stored in a memory unit of the controller;
• and
• at least one sensor disposed in electrical communication with the controller, the at least one sensor detecting a position of each actuator or a position of the blade;
• wherein, the controller executes the control logic to determine if the wing portion is angled relative to the main portion, determine if the first actuator is being actuated to change an angle of the blade, determine a desired pitch of the blade, and control the position of the second actuator until the pitch of the blade corresponds with the desired pitch.
