Hello...new to the forum. I own a 2005 John Deere LX280. Been a great mower for almost 20 years. Has about 700 hours on it. Was looking for a new model that's as close to this model specs as possible (size, hp, deck size, reliability). What are your suggestions? I'm guessing the 300 series? Don't want to get something that's not as heavy duty yet don't want to get something that's too big and beyond what I need. Mainly mow and pull a leaf bagger in the Fall. About 1 acre and pretty flat yard. Thanks for any suggestions.
