Abstract
A digging machine such as a face shovel is controlled in an automated dumping sequence in which the bucket is pivoted to a first angular orientation before opening and, optionally, re-orienting to a second, slightly more forwardly inclined angular orientation. The first orientation may relieve the front part of the bucket from the load while the second orientation is selected to discharge the load at an optimal trajectory. The bucket may move to a third angular orientation before closing the front part against gravity.
