I watched several videos on a Combine Harvester's inner workings and I still don't understand how this thing works.
Stationary processing of grain. Then stationary automated processing of grain. Then add a cutting machine (from harvesting hay) and self-propelling and you've got your combine harvester.
The loading thing? A extruder on a swivel, old tech.
