Alan,I believe that Claas made the 8570 for Massey Ferguson, have always heard good things about that Massey model, the only question sometimes is the Perkins engines that were used, is it Turbo-chargedIJIf it is you have to pay close attention to the air cleaner elements, cleaning them out every 50-75 hours in wheat and beans and every 75-100 hours in corn.Also religous oil changes.Good luck,have a safe and bountiful harvest!!!!
