ncservice,
I have a pump and motor for each wheel. I also noticed there appears to be a leak on the right motor. It is not very bad but there is build up of the oil, dirt and grass. the left motor is clean as a whistle. The dump valves are tight. I bought the mower used so I am sure there will not be any warranty to hope for. I am going to look into the leak on the right side. I think that is where the problem is. The hydro fuild and filter where changed out about 20 hours ago. When I bought the machine I did not think to look at the motors, everthing else looked great. I was aware of the pulling problem too. I just figured it could be an adjustment. Live and learn. I will figure it out. Thanks for all the help. Any ideas on a good place to get a new motor. I guess it could just be a seal that is leaking and causing low pressure??
