I just purchased a new 2002 52" Lazer HP 23Kawi. I have a Dixie that will move to my backup mower. While I have had almost no problems with the Chopper I have just read too many wonderful things about the Exmark. Plus the dealer seems better and much much closer. I'll let you know which one I prefer once I get a couple hundred hours on this one. BTW I went with the Kawi on the advice of the others here. Seems to be a smooth running engine but it has a small backfire about 5 seconds after I turn it off. I let it idle for 20-30 seconds before shutdown. The mower has .2 of an hour. Is this just because the mower is brand new? I hope it goes away.
