We have a 2000 Hustler 4600 Range wing, We have been having a problem with it for almost a month. On one of the wings the hydro filter keeps blowing gaskets off of it. I does not matter what it is doing mowing, not mowing ect. IT blows off and fluid goes every where. We have tried different filters and such but it still keeps happening, we brought it to the dealer and they could not find anything wrong with it. Just the gasket is blowing off, for a quick fix in the field we just unscrew the filter and put the gasket back on and it will last another three hours or sometimes the rest of the day. Any suggestions Let me know. Thankyou in advance.
