I just bought a john deere 2130 with a 145 loader the loader has no power and is jerky. I think they have hooked the hydraulics up wrong place would any one know were the hoses are to be hooked up on this tractor?
1st thing I'd suggest is change hyd filter & check/clean hyd oil sump screen. Pressure oil for FEL control valve should come from the rear of pressure control valve down by hyd filter and oil returned to hyd filter cover via a ported filter cover.
