I have a Toro Z 500 series (I think) that has 575 hours on it, year an half old and we ran the wheel motor out which destroyed the hydro pump (according to dealer) He says that were rough on the equipment like spinning wheels, turning on cement ect. Then threatens not to warrenty the mower. He has had this mower since last Friday and just ordered parts today. Thursday at the earliest - now he has no other mower that he will let us use and I need the Z. So now I think I will rent a used Kubota (132hrs) and he was like well go ahead. I think for the hassle - some one else should pick up the tab? Maybe I am just venting to much here but after the last couple years and $100K from my toro dealer - now nothing. I have three other Z's running, 3 toro 44's wb and I don't have an extra mower sitting around like some of you guys. But I am thinking about it now.
