The only thing worth the difference is the deck. Don't get me wrong the machine's themselves are built well. But so are many machines these days. Gravely builds a great machine. We used them for many years. The deck though! That's where it's at.Thank you all for the input… definitely helps making my decision. Originally wasn’t planning spending quite that much but I really do like the Scag and it appears from the comments that it’s worth the difference.
