Abstract
A system for automatically controlling the position and level of an earthmoving implement on an earthmoving machine. The system includes at least one hydraulic actuator adapted to raise and lower the earthmoving implement, a device for delivering a pressurized fluid to and receiving pressurized fluid from the actuator, and an electronic control circuit that includes electronic sensors for sensing the absolute orientation of the machine and the position of the actuator, and a controller for receiving outputs of the sensors, calculating an amount of the pressurized fluid that must be delivered to or received from the actuator to achieve a desired position for the earthmoving implement, and control the delivering-receiving device to deliver or receive the amount of the pressurized fluid to achieve the desired position for the earthmoving implement.
