A hydro on my ferris went. The whole spindle came out and there are metal shavings in there now. I know its done because there is alot of shavings. I am looking at around $1000 for a new pump. Unfortenatly I will be using this for a back up just as soon as i make enough for a new Scag or Exmark hydro. One a good note I am at least getting better with the trimmer and edging. I no longer go through a spool of string per house.
