Earlier this year, John Deere remotely locked its equipment after Russians stole it from a farm in Ukraine, and it has done the same on construction sites in China to comply with the country’s financing policies.

In the video posted by Sick Codes, you can see how the game plays as a sort of transparent overlay on top of the John Deere user interface (UI). Unfortunately, gaining root access isn’t all that simple without the right equipment, but Sick Codes told Wired “it would be possible to develop a tool based on the vulnerabilities to more easily execute the jailbreak.” John Deere’s technological grip on its tractors goes beyond barring repairs.
