Guys and gals, I'd appreciate some input on this scenario: I have a customer looking at buying a low houred (under 500 sep. hrs.) STS combine. He thinks he wants a 9860, but we are comparing that model of combine against a 9760. He will be combining wheat (mostly dryland with some irrigated) and then harvesting corn (200-240 bushel/acre) and milo in the fall. His ground is very flat. My question is: will the performance/capacity of the 9860 be enough in those harvesting conditions to justify buying a 9860 over a 9760? Any and all input would be greatly appreciated. Thanks!
