ABSTRACT:
A method of loading a truck with material using a loader includes a step of determining a target load for a final pass. Material is loaded into a bucket of the loader in excess of the target load. Excess material is dumped from the bucket back to the pile in a controlled manner to arrive at a target load of reposed material in the bucket. The target load amount of the material in the bucket, which is less than a total amount of material originally loaded in the bucket is dumped into the truck by pitching the bucket. The bucket may be pitched to a determined pitch angle that is based upon the target load using an appropriate material curve stored on the loader. The pitch control algorithm can be calibrated by sensing the reposed weight of material in the bucket, and comparing that to an expected reposed weight, and then updating one of the material curves if there is a deviation.
