Hey all! I am new to the forum here and have been watching from the sidelines for awhile, but I think I need to post my specific issue to get some help figuring it out.
The problem is with my mother in-law's 2120 John Deere (the old model). Several years ago, she had a local handyman install an Allied FEL on it. The loader and hydraulics didn't see much use for several years, except to lift a roto tiller on the 3 pt to till the garden occasionally. Now that I have been using the tractor a bit, I have noticed that all of the hydraulics are painfully slow, including the FEL lift, tilt and the 3 pt. Sometimes, when using hydraulics, for example, lifting the FEL, the loader will be lifting slowing and then it will just stop and you can't move it up anymore, but interestingly enough if I let the clutch out and start moving the tractor the hydraulics begin to work again, albeit still very slow. There doesn't seem to be any vibration or chattering or anything, or anything sounding like air in the lines, but occasionally I can hear a whining noise, which seems to be intermittent, when not using any hydraulic valves, but sounds almost like it comes from the valve spool for the loader.
I have changed the hydraulic fluid, changed the filter, and cleaned the inlet screen so far. I have also tried to adjust the speed with the knob at the back of the tractor, but it seems it was already maxed out.
I grew up on a farm, driving tractors big and small, and know that these hydraulics should be much faster. The loader will still lift a big round bale fine, just very slowly, so it seems the power is still there.
I have concerns, since this loader was installed by a guy with questionable experience, and since this loader is aftermarket, with an aftermarket valve spool to control the loader, that something may have been done wrong, or that something may be wrong in the valve spool. Since it starts working again after putting the tranny in gear and engaging it, I wonder if this causes some shift in pressure that allows a valve to open or close, which may have been locked up causing the loader to stop.
Anyway, I was hoping by describing this situation, that someone might have an idea what is going on and could point me in the right direction to get this thing working better. Thanks for your time!
