I'm looking to purchase an Oliver 550 with a front end loader from my neighbor that's been sitting in his field for the past 3 years. It appears to be in decent shape. Replaced the coil, had no spark, rebuilt the carburetor, fired right up. Loader seems to work well. Right brake appears to be locked up could not get it to move, but the left tire was spinning trying to move. Tires are in fair shape, power steering cylinders look like they may be leaking. I have not been able to determine what year its is. Model number is 55-2118, serial number is 162278-01. I've tried looking it up but can't find it anywhere. Appreciate any help, also wondering what would a fair price be?
