Machine payload measurement dial-a-load system

A method of loading a truck with material, comprising the steps of:

• loading material into a bucket in excess of a target load;
• determining a dump control parameter based on the target load;
• dumping an amount, which is less than a total amount loaded into bucket, of the material by pitching the bucket according to the dump control parameter;
• wherein the determining step includes a step of determining a desired pitching duration based on the target load;
• and
• the pitching step includes pitching the bucket for the desired pitching duration.

• determining a dump control parameter based on the target load;
• dumping an amount, which is less than a total amount loaded into the bucket, of the material by pitching the bucket according to the dump control parameter;
• determining a deviation from horizontal of a loader that includes the bucket;
• identifying the material in the bucket;
• and
• the pitching step is also based on an identity of the material in the bucket and a determined deviation from the horizontal of the loader;
• sensing a reposed weight of material in the bucket following the dumping step;
• comparing the sensed reposed weight to an expected reposed weight;
• the dumping step is performed according to stored dump data;
• and
• calibrating the dump data for use in a subsequent dumping step based on a difference between the sensed weight and the expected reposed weight.
