Yeah,Maurer is the one. I wonder why IH didn't pursue this a long time ago.I can see why there might have been some issues with the standard rotor in the beginning,but after they perfected the spec rotor,there should have been a better front. It had to have taken a lot of head-scratching to figure out the elephant ears with the bend and all,and then to use them as an agitator while the cone vanes screwed the crop in. Seems like the inverse way to go about it,but then I'm not an engineer.
