This paper presents an overview of a planning tool being developed for the generation of routes in the spatio-temporal domain for vehicles participating in capacitated arable farming operations. The planner supports processes where the field is divided into a surrounding headland and an inner-field (main) region. Two scenarios for output material flow operations are currently supported: 1) one machine equipped with a container works the field; and 2) a machine with no container works the field while being serviced on-the-run by one or more capacitated service units.
