content: There is a YouTube video floating around where a farmer is forced to learn how to "hack" or rather in this case, I think he   7bc2  learned to modify firmware files using a hex editor and an unzip utility, and it shows him hacking the firmware on his tractor so he can.continue to actually use it each year.  It's so great to watch this farmer with these big farmer hands, tapping away at a laptop keyboard, and uploading the cracked firmware to his tractor or troubleshooting and posting on Chinese language farmer forums and hardware hacking forums.  great.
