Fair to say that it is a matter of perspective, but by your perspective the cultivator is a robot, right? A field is far less structured than a barn, and the tool makes decisions about how to alter its behaviour and environment in a pretty grand and visible fashion. Lely products are much closer to being automation in comparison.
Perhaps a more pedantic take is that the cultivator is simply attachment for the actual robot, which is the tractor. A cultivator on its own is useless. In that vein, there is seemingly a difference. Each product Lely sells is the full solution. Whereas John Deere gives you a menu and you have to select which "toppings" you want on your robot.
But then that gives nod to Lely products being closer to automation than robotics again. Beyond choosing a product at a high level, you don't have to get into the nitty gritty details because they will always operate in a comparatively strict and consistent environment.
