Farmer here. I've been saying for years to my fellow farmers that equipment security shouldn't be dismissed.<p>I did not focus much on tractors, though, but automatized irrigation systems that allow remote access and configuration. When choosing my own options, and since I never had the information I needed, I always chose the simplest solution, i.e., local manual configuration without remote access.<p>Around here the public water supply is remotely controlled, but like an Intranet, via optical fiber. I suspect this has to do not only with poor reception in remote locations but also with security. But water meters are accessed via SIM, I think.<p>Every time I mention any concerns with security, however, these are met with skepticism. The usual inability to foresee third-parties' motivations, in variations of<p><i>"Why would anyone want to interfere with my equipment?"</i><p>are very common. And I admittedly lack the skills to raise concerns for this issue past saying that ignorance of threats doesn't make them go away. My only hypothetical case is systematic crop failure due to poor irrigation associated with futures markets that depend on yields.
