From what I can tell from my other thread, it is a bit unfair to compare the Mini Z with the Gravely 252m. So if the correct comparison is the Gravely 252M with the Super Z, which is the better? They have quoted the Mini Z with 19hp Kohler for $6599 and the Gravely 252M (25hp Kohler) @ $6799.00. I have no idea what they would quote a Super Z XR-7, but I'm sure it would be $7550+. I really don't won't to go over $7k? So which should I purchase?
