Abstract: A system for automated control of a machine along a first slot in a work surface includes a machine position sensor and a controller. The controller is configured to determine an elevation difference between each pair of laterally aligned positions of the first slot and a second adjacent slot, generate a first propulsion command to operate the machine according to a first propulsion mode while the machine is disposed along the first slot adjacent each pair of laterally aligned positions at which the elevation difference is less than a slot elevation difference threshold, and generate a second propulsion command to operate the machine according to a second propulsion mode while the machine is disposed along the first slot adjacent each pair of laterally aligned positions at which the elevation difference is greater than the slot elevation difference threshold.
