New to me JD 2440 and JD146 loader. Started using the tractor after replacing the radiator, changing fluids, filters and a little welding on brackets. Noticed the bucket starts to droop slowly and at the same time the loader starts to raise some. Otherwise the loader and bucket work fine. It will lift the bucket full of dirt with no problem. We did find the bottom of the joystick controller wet but not dripping fluid. Both bucket cylinders leak at same time/rate. It doesn't seem possible for the fluid to leak between the bucket and loader valves inside the joystick controller. It seems more likely that the two are separate indications of needing repair of the controller. Right now it isn't a big problem, just an annoyance. Any thoughts?
