I have pretty serious leak in the pump area and under the seat where the return line comes out of the rockshaft housing. I have a service manual for directions of removal of pump. I would just like to know if there are any tricks of the trade or advise anyone has to help out. Several of you have given suggestions on the leak under the seat. I thought I had that fixed but it seeps fluid, so I'm going to have to look into that a little further also. I see there are "kits" available for the pump and the pipes, who do you suggest getting them from, and part numbers? Any help or experience from you would be appreciated. This our 1st JD, something with hydraulics, so I'm new to all of this.
