I've got hydro fluid leaking out of the top of my reservoir where the cap goes on. I was thinking It was due to going over some steep terrain the other day but nup..........I just backed it off the trailer and the same thing is going down. Also the screw thread is fine. This is a "new" mower and only has 8 hrs on it and It has NO dipstick in the reservoir so I can't tell if it's over full or not. The dealer gave me an owners manual but its for the Chariot jr not the Chariot so I'm a little peed about that but I'll get the correct manual on Tuesday. I need a quick fix! Thanks! BTW: these hydro tanks are built to breath out the top[ where the cap goes on..............Correct??
