| Absolutely not. The "new" cleaning system of the 9870 is a fine example of marketing people playing and pretending to be engineers. JD has long known they have inadequate cleaning and shoe capacity on the larger STS machines and that they fall short relative to the competition. So, marketing decides to add a $500 extension to enlarge the area of the prechaffer so that they can publish a new larger cleaning area for the 9870 and call it a "big" combine. Don't be fooled by it. The only way in which it may help boost capacity relative to what they had before is that it could potentially make it more difficult for corn to back up into the cleaning fan ala it being carried farther back onto the shoe before being dumped or cascaded onto the main chaffer. Even if you were to run a 12 row head, a 9870 is going to be pretty limited in those yields and with higher moisture corn even more so. If I sound unimpressed, I am. I just expect more out of JD than that. | |
