On Oct 24, 2019  we had a 40 mph wind gust that caused the turbine to furl and it got stuck. The guy we bought it from said that was the only thing wrong with it, that it gets stuck in the furling position occasionally.
  We had beautiful weather on Saturday so we took it down to unstick it, plus to see if we could figure out why it was stuck.   I googled it and I does seem to be a known issue with the South West. They found it to be furling bearing friction.  But when we inspected it, it was still well greased and moving fine. But it seems there is a point you can reach that it sticks in the furled position.  There is a rubber pad that seems to be there to stop it from going that far, but I suspect it is worn down.  We improvised by epoxying a metal washer on top of the pad, hoping that the washer will stop the furling from going too far.    The turbine is back up and running fine so far. I guess we will see when he next high winds come if our kluge of a repair worked. 

The hydraulics on the tower were very slow raising and lowering the tower, it took about twice as long as usual.
