Hello, This is my first post and am looking for some advice. I am in the market for a compact tractor and have prices on the models listed in the subject. THe b3030 and jd4210 are within a few hundred dollars of each other. The b2630, which the dealer tells me is more comparable to the 4210, is 2k cheaper. These are all equipped with loader, tiller, and brush mower. All hydrostatic. Turf tires on jd, others r4. Dealer won't change tires on 4210 because it is discontinued and new bolt patterns are different. Any help would be appreciated. Thanks in advance.
