There are vendors with more basic equipment. But John Deere's selling point is the complex features they offer. I watched some farming YouTube videos and I was surprised by the technology in modern tractors. The tractors will drive by themselves and they'll keep track of what land they've already covered, help you align, let you control how many seeds you're planting per acre, etc. It's all very high tech and a single person in a single tractor can cover a massive area and their job is mostly just to supervise the tractor and make sure they don't run out of seed or whatever they're putting down.
