Surely you’re just messing the soil / compaction and drainage for next year? Why are you not using imposed load trailers like uk, rather than bogie trailers to improve your traction? Or half loads with one tractor rather than use two?
Im not a profi but what speaks agains loading the trailer just to the half and save time for the towing? Or build a (i dont know the name) a big bagpack for the tractor.
