Automatic tool tilt command system

An automatic tool tilt command system comprising:

• a work machine having a chassis connected to a boom, a tool, and an input device;
• a lift cylinder connected to a hydraulic system and the boom;
• the hydraulic system having a first electronic control valve, wherein the first electronic control valve is configured to control a flow of a hydraulic fluid from the hydraulic system to the lift cylinder to control movement of the boom;
• a tool cylinder connected to the hydraulic system and the boom, wherein the tool cylinder is configured to move the tool;
• the hydraulic system having a second electronic control valve, wherein the second electronic control valve is configured to control the flow of the hydraulic fluid from the hydraulic system to the tool cylinder to control the movement of the tool;
• a control unit having a predetermined flow ratio and connected the hydraulic system, wherein the control unit is configured to transmit a boom actuating signal to the first electronic control valve and a tool actuating signal to the second electronic control valve such that the flow of the hydraulic fluid is changed;
• wherein, based on the predetermined flow ratio and an input command from the input device, the boom actuating signal and the tool actuating signal are contemporaneously transmitted by the control unit to maintain an inclination of the tool about a horizontal direction as the boom is moved.
