Abstract
A system and process for controlling propulsion of a track trencher excavation machine includes a multiple mode propulsion control that performs a plurality of functions depending on a selection of one of a plurality of operational modes. A computer modifies the functions of the multiple mode propulsion control depending on a selected operational mode, and coordinates propulsion of the engine and track drives of a track trencher in response to signals produced by the propulsion control.
