[quote=@Dinh AaronMk] As someone whose worked with shop folk and the sort of people who have to repair equipment like tractors for the better part of seven to eight years, it's usually not that easy. There's not a lot of standardization across brands and doing simple shit like re-tapping holes is a massive pain in the ass and can easily turn into a horror story. And when you get machines as big and complex as these: It can get insane. And they're already uncommon machines as-is. I'm sure a few enterprising persons can wrangle it. But we also come into the roadblock that is access to the materials. And even if you can get all the bolts that can take the sheer force of working on equipment like that you come to the issue where you're not going to have much in the fuel and producing the ethanol to the quantity to keep them in the field is going to eat into food output and effect end-result food costs. Ethanol is also murder on engines (for example: alcohol holds onto water and when so much water gets into the engine it murders it, so when higher concentrations are introduced in the fuel then there's a greater and greater risk water will be present, alcohol is also corrosive and can eat some of the non-metal parts in an engine) so when the finer components in motors are murdered on a cut ethanol blend you're not going to replace them. They'd hang on, but not for long. And soon you'll be forced into smaller plots so the same small team can manage it all on more antiquated supplies or you're going to need to pull in more people from the larger community to help, cutting into an already limited population that'll cut on people doing innovative work so that they can eat. [/quote] Well ethanol is one thing. So what's the rule on proper oil? Alberta is one of the richest oil reserves in North America. It's literally mixed in with the dirt. You can just filter the crude out of the ground. As for parts, are there no machines anywhere in America anymore? Surely it could be traded for. And as for being a pain in the ass, these are religious zealots who are banned from enjoying any type of entertainment. All they do all day is work. Fixing a broken engine would almost be a relief, because it would be a break from doing the same thing every day of their bland lives. I think it could hypothetically work, but it's up to you guys. If not, can you tell me if horses exist in this world?
