The Case 440 is much heavier than the newer CUTs. I would be nervous handling round bales with most 30 hp CUTs unless you are doing it on the 3 pt. The weight on the front end when hitting ruts and obstructions can be tough on them. Of course the bigger you go the more they cost.
agreed....add hills to the above scenario on a smaller CUT w/ round bales, and you have liability to say the least.
