Abstract
A wheel loader machine includes a bucket configured to hold a predetermined load of a granular or powder material, a hydraulic system having an electro-hydraulic actuator to move the bucket over tilt angles and to shake the bucket, a hydraulic sensor configured to detect hydraulic pressure, an interface configured to receive input parameters and to output status information of the bucket, and a controller. The input parameters including a target weight of the granular or powder material. The status information including weight of the granular or powder material in the bucket determined using the detected hydraulic pressure. The controller configured to control the hydraulic system to tilt the bucket to a predetermined tilt angle and to shake the bucket in accordance with an agitation pattern until the weight of the granular or powder in the bucket is at or below the target weight of the granular or powder material.
