Hi Bigsky No, this year I havn't checked it but last year I leveled the concaves and I was setting on "2" when cutting Milo. Nothings changed to that machine or had any work done to it back there to cause anything else to go out of whack to my knowledge but if memory serves me correctly, when the concaves move on a deere it is the rear that is brought closer to the cylinder while the front is the pivotal point. I might be wrong but going on memory it seemed to me that was the way it worked. This humidity we are working in isn't helping anything either. 10 o'clock this morning it was still 69 percent humidity. Got down to 49 percent this afternoon again but by evening back in the 60's again. We arn't getting started before noon and we are quitting at dark because of this high humidity. It just makes that cylinder growl and even Fathers axial flow is suffering from the effects of it this harvest as well. Just keep hammering away a day at a time. It'll be a longer harvest than usual with lower yields, lower test weights and high than usual FM dockage but at least there is something to cut. 1 field tonite that got hailed on made 32 and another made 20. Go farther north and those wheat fields made 2 bales to the acre......lOl. Count my lucky stars I can be out in the combine and not the swather or early with the disk and tractor.
