Where is the power steering fluid reservoir located ? The power steering unit has been repaired at least three (3) times but continues to leak . I'm thinking of adding some Lucas power steering stop leak to see if this will cure the problem sort term. Is there a negative to using a stop leak additive ? Thanks for any help or ideas.

Power steering is part of the hydraulic system. No separate reservoir

I just purchased the tractor knowing it had the leaking issue. The unit is under the dash to the top rear of the motor. The previous owner told me that the unit had been repaired by a certified AC tech two times and sent off to an outside repair shop and it still leaks. My next step is to power wash the area of the pump and try to determine where the leak is. The currant condition is such that the leak is a stream and not a small stream.

Might just be a loose connection or bad hose end.
