    Anyone have problems with the hydro pump belt tension spring breaking? I lost one today and the mower almost has 50 hours on it.

    Yes, there is a service bulletin addressing this issue. The problem is supposedly out of balance pump pulleys. Contact your dealer they will warranty out the old one's for new updated pulleys. Make sure you check the pump idler arm for any wear at the spring contact point.

    Got a copy of the bulletin? I would like to take it with me to avoid arguing with the dealer.

    The dealer or mechanic has the bulletin, my mechanic showed me his copy.

    If you have problems resolving this I can scan my workorder and email it to you.
