I need to know if anyone has had any problems with the zg23 AT ALL I am looking at a demo unit, last years model(2006) with 9hrs on it, i didn't like the idea of another stamped deck machine and I noticed that the belts looked more fragile and less accessible than on the toro z500 estate series. My second question would be about the toro is it necessary to get the z500 with the larger engine and the turbo force welded deck unlike the estate series with the component deck and no turbo force? Can anyone tell me the difference? PLEASE! Any other suggestions about mowers or comparisons? Is 6500 a good price for last years demo unit of a zg23 54" it's a kohler with 9hrs?!?!?! I was thinking it seemed high and i saw a unit on ebay that sold for 5700 with 18hrs in nearly the same situation... Here's what i need to mow 2.5 acres 1.5 lawn 1 is a "field" which is actually just grass that the previous owner and myself were too lazy to mow with a 42" POS tractor. Please help the kubota comes tomorrow and i'm sure i'm going to love it but i'm looking for a dependable machine and the belts driving the blades are a major concern.
