Yes. I'm switching to a 30 so much better, but I need to keep my 21" for one lawn that has such a small gate. Haha.
I understand that there are differences, but the closest dealer is at least 26 miles away. That would take me at least 30-40 minutes one way. Compared to my Toro dealer that is only 5 minutes away.
Try tipping the 30" mower on its side to get through narrow gates. Not too hard to do.
