I've got my Toro 30 in the shop now. I broke my blade twice, the second time I took it to the shop and it wasn't until after that I got the recall. It has something to do with a washer in or on the spindle that was wearing prematurely and causing vibration in the blades. Toro is fixing everything under warranty.
Had the chance to buy a commercial 30 for 850.00 from a guy when they first came out but I past on it cause there was no reviews on it at the time I didn't know enough about it other than I knew it was a steal for a 1500.00 plus mower
