I'm about a day away from replacing my 16HP Walker and buying a new 26 EFI model. Today i started chatting with another "Walker Veteran" that recently swithced to a John Deere mid-mount ZTR with bagger. He swears up and down that his JD is twice the machine that his Walker ever was. I have tried ZTR's before, but not for any extensive time. I don't have much time at all right now to go demoing a bunch of machines. Can anyone out there, that has done the Walker thing and the mid-mount ZTR thing, give me some opinions?
