Does anyone know or use the JD ZTR's for commercial use?? I used a lot of John Deere equipment many years ago when i worked on a farm and loved it!! But i have'nt heard much about the ZTR's. What about the trimmers and blowers?? Does anyone use them commercially?? My local JD Dealer is just down the street from me and it would be very handy to buy equipment there. Any feedback would be very helpful, Thanks!!
