Stop in for a cup of coffee

So go to cut the street part of the lawn yesterday working great then it acted like it was clogged up with grass. Lifted it up turned the blades on nada on rotation. No roaton on the jack shaft at all. Look at the sight glass for the HYD oil, Milky again. Crap need to do a full system flush again and $200 in filters! Go online start looking at reasons how water is getting in there it is a totally separate system. Shift boots seem to be the reason on most of these models. CRAP!
