Abstract
An excavator includes a dipper assembly configured to receive a dipper load, the dipper assembly having an actuated position for emptying the dipper load, a sensor assembly configured to monitor one or more operating conditions of the excavator, and a control module. The control module is configured to receive signals from the sensor assembly, determine a height of the dipper assembly relative to a surface, and inhibit movement of the dipper assembly to the actuated position.
