Ive been having a rash of annoying breakdowns this season. Last week while half way through a lawn one of my double wheel belts snaps (never had that happen). Last night the mag-stop clutch blew out on my Toro wb. That must be rare too, because when I called all of my local dealers no one stocked it or could remember the last time they had to order one. Im looking to buy another walk-behind this year (possibly used) and I was leaning towards a hydro, but after all these recent breakdowns I am getting leery. I understand the cost to replace hydro parts is astronomical. How reliable are the hydro units will I be sorry that I bought one? I replaced both wheel belts for $80, but I hear that a hydro pump or wheel motor is $900!
