I'm planning on updating to a 2188 but probably not before next harvest. I've got a line on a super clean 30ft head and wondered if my 1660 could handle it. I'm in south dakota and our beans are normally dry and short when we harvest them. I guess i'm not too worried about the intake from it i'll just go 20% slower, than my 25ft head. But will the smaller feeder house support the added weight? thanks!
