I now have hydro fluid leaking from my 1 year old TTHP. It seems to be comming from the top and flowing down over the sides. My dealer replaced the cap and it didn't seem to work. They are working on it now but I was just wondering what you guys thought it could possibly be and has Exmark had problems with this ?. Now I noticed that my 2 year old TTHP is now leaking also from the top. Thanks for any help and thoughts you can give on this.
