From what advice I've seen on Lawn-site it's highly recommended to demo a lot before you make a final decision. So far I've demoed a Hustler Super Z for 1 hour, and a John Deere 757 for about 3 hours on my property, and a Kubota ZD-28 for about 15 minuets on another property. I would also like to try an Exmark Lazer Z on my property, and possibly the Kubota ZD-28. 1. What is a fair amount of time to do a good demo? 2. Can too many demo's cause confusion? 3. Is it best to buy a ZTR in the fall or is it better to wait till spring. 4. would buying a demo be a good idea ?
