I have a 5042 Kuhn twin vertical mixer wagon with new Kooima knives and it takes forever to grind and mix a bale of medium stem brome hay. How can I help the efficiency of the mixing and tearing up of bale with DDG and soy hull pellets for stock cows? I don't want to grind the hay as I don't own a grinder. I would have to hire big bales ground and have a big pile of hay getting wet. TIA Seenitall
