I am trying to isolate the problem on my mower. When I push the right arm of the Z turn FERRIS mower I hear a chattering noise and have no or very little movement forward or backward on the side of the mower. I think the problem lies with either the right wheel motor or the hydrogear 12CC pump. Does any one recognize this problem and can help me isolate the problem so I can order the right part to fix my problem?
Thank you
Mike
