I have a Farm Pro 2425 and when i lift the 3 point with my brush hog hooked up I have a hydraulic leak. On the right side under the seat(the right side as your sitting on tractor) there is a hose which i believe they call a banjo fitting on the end.It has a bolt going through it and hydraulic fluid leaks a pretty good drip from there when i lift the 3 point.Do these have o-rings in them or do i replace the whole hose?Any help would be greatly appreciated..
