Your timing is good--I just finished mowing 2 of about 3.5 acres of grass on rolling hills with my 2230 for the first time. It wasn't too bad. I went sort of slow since this is the first day in two weeks the lawn has been dry enough (but not completely dry) to cut. This tractor is larger than my JD L130 (which I used last year and traded in to get the 2230), but I would say the JD was maybe more bouncy but less jolting. One thing I like better about this tractor is that it seems to handle much better, so turning into the hills going up and down seems to ease the back factor. I have a herneated disk in my lower back and while I'll be a little sore, nothing too bad.
