Palat, I'd go with an exmark, I had a snapper hydro that was amazing, but the service in our area just isnt there. I have 2 toro's but they are belt drive which I hate. My new exmark is going to be the ticket. You should really get rid of that old z mower and upgrade that, I saw it more @ the rental than out cutting.lol. Gotta find good help too, Franks a good worker, but he just has his own demons. I tried 2 people in his place this year and things really didnt work out. This year I'll try him again, but the everyday pay and borrowing money isnt going to fly.
