Abstract
A system for controlling a ground engaging work implement includes a machine position sensor, a work surface position sensor, a work implement position sensor, and a controller. The controller determines the position of the machine, determines the topography of the work surface, determines a location of a pre-task trigger location adjacent the task start location, and determine a position of the lowest surface of the ground engaging work implement. The controller generates traverse signals to propel the machine from the task end location towards the task start location, generate work implement height signals to maintain the lowest surface of the ground engaging work implement at or above the traversing threshold height as the machine travels from the task end location towards the task start location, and generate work implement lowering signals to lower the work implement to the pre-task threshold height after the machine passes the pre-task trigger location.
