I'm sure not many people on this site have a 580D Toro but you never know. We have 4 of them and I'm displeased about all the downtime that we are experiencing. One of which is broken belts, I also have a problem with the height. If I use the cart on the mower and then take a tape and messure it's never what it should be. I could be off as much as an 1". Anyone else experiencing this?
