hi, I'm a 16 yr old who has been mowing on ztrs for years and have been doing just the "neighborhood kid" business for a while. I have a what i believe is an awful mower, Toro Timecutter ZX. This mower makes me double cut everything even with sharp blades. This upcoming spring i am purchasing a trailer and finally starting somewhat of a real business. I can trade my timecutter in at the dealer for 3,000 since it is in fairly good condition. I will probably have around $3,500 to $4,000 to spend on a decent commercial mower. I am hoping i can find a good deal buying used. Could you guys help me out with what you think is a good mower for my situation. It has to be a ztr rider with at least a 52" deck. O and by the way i live in davenort, IA and if any of you guys are selling that would great. I would appreciate any suggestions.
