We just purchased a 9610 combine and are needing to match this up to a corn head and we are debating between 8RN and 12RN. Normal yields are in 150b/ac range and I like the idea of driving slower and keep the combine full. Will a 9610 handle it? It has PRWD with 520/60*26 tires on the rear 20.8*38 duals on the drive. Thanks for help. Paul
