Several questions today just as most of you have. I see a lot of internet ads selling new farmtracs with a third party warranty. Who is this third party and if parts are just being handeled through a cooperative dealer effort how can anyone offer this third party warranty? My local dealer I believe is not aware of the the parts cooperative and I need to know how to get him in contact with you other dealers so that his parts searches are less of a nightmare. I still like my 555DTC w/loader but I under powered myself and now wish I had bought the 675 DTC w/loader. Any problems with the 675s. Want to know if this would be doable. Trade my 555DTC for 675DTC.
