I need some help on this subject. I have a 9N with a 5' bush hog that I use to mow my 10 acre field once a month. I want to buy a new tractor with about the same dimensions as the 9N so it can fit in my shed. One dealer told me the TC30 is fine and another said it's not powerful enough to pull the bush hog. Is there any big advantage getting the TC29 or TC 33 over the TC30. Money is a factor here.
