Tractor to run rb564

Just got a new to me rb564 premium baler, traded in my 660. I run a white 2-105 tractor to bale with. I know they both are 5x6 balers but the rb is quite a big bigger and heavier? Never had issues pulling the 660 but I’m wondering if this new baler will take more power to run? Western pa with some steep hills
