Sounds like a while since you were on a farm! Plenty of backpackers operating big harvesting machinery in all areas. Your description of neighbours working in teams sounds idyllic, but not widely adopted in modern times. With many farms using multiple harvesters or contract harvest operators, the owner is more likely to be found coordinating the process, marketing grain, and filling in where needed. Some smaller farms don’t even own a harvester. Too much $$$ siting in the shed for 10-11 months of the year. That said, your description reminds me of my late teens on our small family farm. Big brother in the harvester, the only vehicle with aircon, Dad moving bins and support equipment, and me hammering down dusty track getting as many 8 tonne truckloads in to the local silo as I could!
