It's been over a decade since I worked on a farm but back then it was common during harvest season to have a tractor and disc hooked up in case a fire broke out. Everyone had one set up because it was in everyone's interest to stop the spread ASAP. If your neighbors field caught fire you'd still run your tractor over to help.
