I have a 2000 JD4300, recently I blew a steering hose and lost a lot of fluid before I caught it, fast fwd new hoses and fill the fluid to sight glass and now it seems awful slow across the ground, FEL, grade box and 3 pt all seem to work fine but I'm an electrical guy not a hydraulic guy and FYI this is my first tractor. Thanks for the advice in advance.
