From what i've heard, Cummins wants out of the AG business. Don't know why they just do. All new Massey Combines will have the Sisu engine. Not sure on Gleaner. Did hear the Sisu will go in the Gleaner but also heard AGCO will put one of their own in there. Just like they did in the new DT series. The Sisu is the biggest improvement. If you don't could the old White Rotor going in. Take care, Nathan
