Hello everyone. I've been thinking a 550 sure would be nice to have in addition to my 770. Probably wont happen anytime soon since I'm still trying to finish a degree that seems to have no end and thus money is a little tight, but would like to know a little more about the tractor. Seems everyone who has one loves it. I've used one but only for a very short period, about 10 minutes, but I was pretty impressed. How relieble are the trans/rear end, engines (gas and diesel), and was there an LP option for the 550? Besides the front axles on tractors with loaders attached, were there any other weak areas. If I were to find one it would be used for brush hogging, blading driveways, moving trailers, maybe someday having a 3pt sickle mower, raking hay... pretty light chores plus a 3pt plow for plow days. What size plows and disks were recommended for the 550 in its day? Also, what price range have you folks seen 550s running? Any other information would be appreciated too. Thanks.
