Leak from On High

[djradz]

No I'm not refering to the weather or the Angels or the Good Lord weeping! My problem is that I've got a small leak of hydraulic fluid coming from high up on the hydro transmission on my TC-40D. When I park the tractor after an hour or so of useage, I get several drips/a very small puddle. I've already done a TBN search and could only find a brief reference to some folks having a prior leak from some test ports, but I'm not sure where those are or if that is the same spot or not.

It appers the leak on my 40D is from a fitting/port, or the body/casting itself of the device the 3-pt hydraulic lift drop-speed knob terminates into. I guess I'd call this the "drop-speed control valve", for lack of a better term. This is located at just about the highest point under the tractor and positioned under the platform, behind the seat, but in front of the fuel tank.

Does this sound like anything anyone else has seen?

Duane, I think you may have to take one of the rear tires off to see the test ports clearly, because they are directly under the seat. I can't remember for sure, but I think if you take the seat off, you can also gain access thru a panel. ...don't hold me to that. It's been a long time since I was in there.
