JD 430 help

I have a opportunity to get a good used JD 430 rd baler and a JD 1209 swather conditioner. My question is at the time i have a Massey 245 tractor. I have read it should be ok and do the job as long as I don't bale the 6x5 bales. Put up a lot of hay this past summer with a sickle and square baler, just want to move up to rd bales as they are easier on mine and my wife's back . Will be haying around 40 acres of flat ground (2 different fields 20 acres each). Opinions on operation, looking at larger tractor in near future.
