I purchased a Toro Z500 60" cut with 23 HP Kohler. I purchased the machine last fall and have not had a chance to test it on my 2 ac lawn. For six years I used a 46" MTD rider. This machine was mostly worn out. I'm sure the difference will be like daylight and dark between these machines. I'm just curious what kind of experience others have had with the Toro ztr's. After looking at the Deere, Dixie Chopper, Graveley, Snapper, and Ferris, I just felt like the Toro was heavier built, well made, and closer to simple than all the others. I will say that I was torn between the Toro and the Graveley. Please offer any comments or warnings that you have on Toro.
