as far as auto mation goes, thats how implements used to work. it was a tracter/thresher/combine. then a bale counter is slapped on then maybe row sighting or guidance, etc.
if your really snazzy, the implement is actually mapping the soil for moisture, or rough composistion and holding data to use in reformulating or notating your current cultural plans, i.e. supplemental spot feeding and irrigation.
actual agricultural needs, not just fluff.
Other than ~30min it takes to teach an employee to drive manual it doesn't do anything worse than the modern ones it works alongside and it does a handful of minor things much better by virtue of predating OSHA.
