    I have a knock in the left hydro pump when I'm at an angle and needing to turn right. I have changed the hydro oil and filter according to the users manual. A new belt did not fix the problem. Could it be that the hydro pump is bad or something else?

    I have a similar problem. It started on my left hydro. When on a hill it will lost power and I can feel a purging in the controls. I have to bring the mower to a stop and then move it again. Usually it will move fine. I also hear the purging. I think it is coming from the hydro. I'm thinking air is in the system but not sure.
