Yes, the fan is spinning when motor is running.
I have not changed the filter so I don't know if it is plugged or not. I have a new filter and hydraulic oil so I guess I should change that next.
The "pins" in the two valves on top are completely UP when the knob and plate are removed. The pins move freeley. I had both those valves out, checked for movement or clogging, both looked OK.
My understanding is that if both pins are depressed, that allows the tractor to be rolled somewhat easily. This tractor rolls with the pins completely up or down. The pin/valve location seems to make no difference. When I had these two valves out I could barely see any oil down below the valves. It seems to me I should be seeing hyd oil in that area, shouldn't I??? The dip stick fill tube shows the fluid level to be full. Why would the dip stick show full yet the valve area be low? What keeps the hydraulic oil from getting to the valves? Could the pump not be working properly? Is the pump impeller made from hard rubber as in boat fresh water pump impellers that when left sitting get hard and then don't create good pull when spinning?
Attached ( I think ) is a picture of the trans and differential if that helps any.
Thanks to those who are trying to help me. JD
