I have aproximatley 5.5 acres of lawn. I purchased a JD 4410 CUT a year ago to get all of the heavy work done. I have just sold the CUT and am ready to purchase a new or nearly new ZTR for maintenance. I will not get smaller than a 60" and prefer a 72" cut. I have been using a Bunton 60" ZTR that is several years old. I bought it to make sure getting rid of the CUT and going to a ZTR made sense. It does. We have done and will continue to do all of our landscape around a big mower. We are fairly level and scalping should not be a problem. Especially since I keep my fescue at about 4.5" tall though one day we will start cutting shorter and over seed with bermuda. I still don't think scalping would be a problem. What do you all recommend? A/C, L/C, gas, diesel? I have looked at all of the big ones (exmark, toro, hustler, dixie choppers, Bad Boy, etc) but can't come up with a definitive "this one is better". I have to cut my grass every 4 to 5 days and takes roughly 2 hours with the current 60" Bunton. Are there any I should flat stay away from? Any help would be appreciated, I hope to buy within the week.
