Ok I have a deal pending where I'm going to swap my ZTR for a hydro walk behind w/ same size deck and it does have a sulky. Just wondering if I am going to be sorry. Here are my scenarios My ZTR is an older Grasshopper 225 52" cut w/ 25 Horse Kohler w/ a lot of hours. It runs and cuts great and has never given me any problems, but it's old w/ a lot of hours. 90% of my business is foreclosures that are less than 1 acre lots that 2 guys are in and out in LESS than 35 minutes including cut, trim, edge and blow. (Most are even less than 20 minutes total) I do have a couple of properties (including my yard) where I will cut for an hour and a half or so....my yard is even bigger.....usually about 2 hours of mowing. I'm thinking that I will like a walk behind since I spend more time riding to the properties in my vehicle than I do actually spend at the property. The worst property is gonna be mine for the walk behind but...... Also thinking the walk behind will be lighter for towing purposes thus helping out in the long run. The walk behind is a Lesco pistol grip hydro w/ 52" deck as well that has very low hours and he is giving me some boot, so that is a good deal for me. It does also include a sulky, so it's not like I would actually be walking.....just standing. I haven't actually sealed the deal yet. Keep going back and forth but I'm really leaning toward trading right now. I would love to have both, but child support on 4 kids won't allow that in the budget. Just wondering if y'all think I'd be making a mistake by trading the older rider for a newer walk behind and some boot.
