My Ford 861 tractor loses its prime after sitting a day or so. I loosen the allen head bleeder screw and after a while the oil starts to come out and the lift begins to lift although it does not lift as high as it should even when the pump gets primed.
My first question is, where is the most likely leak causing the pump to lose prime? There is a manifold that connects the hydraulic reservoir to the pump and I assume there are o-rings in that manifold and maybe inside the pump as well.
My next question is what is the most likely cause of the lift to lose lift height with the brush hog attached. Is it just too weak or is it a worn control valve part? When I do get the pump primed, the lift works slower than it should and does not go up very high, it barely gets the brush hog off the ground!
