JD425 lawn tractor; JD4710 CUT; JD JX75 Walk Behind
Try Mark Brucker at KC-Canary-Fultonville, Inc in Fultonville, NY at 518-853-3405. I bought my 4710 through them and they gave me the best price on the tractor package among five dealers I went to.
Try Lehigh Ag (http://jddealer.deere.com/lehighag/) in Allentown, PA. Their prices are very competitive and they will negotiate too. They sell all JD models as far as I can tell.
