I seen a road test where the tester drove the tractor to the pub and set the swath with to the width of the road and the tractor drove him home again hands free.
After the council mower had been used the first time by remote control if the system was decent it should be able to mow it without control next time.
it could also be ran from a system similar to a geofence.
