Was looking through the 2010 summer show photos. Noticed the 840 self propelled forage harvester. Haven't seen one of those in years. Owned one of the 830 pull-types myself. It had a few good points, but generally, the less said about the thing, the better. Did any of you own an 840? How reliable was the self-propelled unit? Quite frankly, Fox really bit Oliver on the butt with those outdated units!
