I have a lawn tractor, so I don't mind it *that* much... Gives me yet another excuse to drink beer...
What I hate though is using the string trimmer to trim around the edges. Kind of difficult to do that and drink beer at the same time.
Now, I tried a friend's zero-turn-radius mower once to see if they were all they cracked up to be. Well, they sure were good for going around the trees and bushes, but it was basically impossible to hold a beer in one hand and control the two steering levers with the other hand.
