Nozzle control system and method

Control systems and methods for coordinating multiple agricultural machines for operation on an agricultural field are provided. Each machine may receive field data for an agricultural field that optionally includes a plurality of pre-defined swaths. Each machine may receive state data from other machine(s). The state data for the other machine(s) may include a next swath and a current swath. Each machine may, after an indication of a start of its current swath, determine a next swath based on open swaths and the state data for the other machine(s). A next swath may also be determined using vehicle kinematic data, and conflicts between machines may be resolved.
