I am having to change the what I believe is the hydraulic fluid filter on my mom's Ford 1520. It is the filter under the seat on the right side. We can't find the manual for it. Going to get one. But I have the filter and some fluid. I think the fill port is under the metal plate between my feet near the dip stick. I am hoping someone can tell me if that is right. This model has the petal on the right for forward and reverse.
