We run a 9660 now and are looking for a little more capacity. Our dealer thinks a 9860 is the ticket. I don"t want to go any larger than the 30 ft straight we have now do to transporting issues. Can I keep a 9860 full enough with 30 feet? Other question is, we seem to be able to load our sieves to their limits now, so how can the larger machine with the same separating area do too much more? We run 3.5 to 4 in 120 bu oats, 4 to 5 in 40 bu canola, 25 ft swaths, 4 to 5 in 50 bu wheat. Do these numbers sound reasonable or am I doing something wrong in my settings? It makes me wonder just how much more the 98 will do. Thanks for your opinions.
