I have a 2001 BX2200. I've owned it for 16 years. 2300 hrs on it.
I have an issue with the 3pt not raising and hence the deck will not raise. FEL is not attached and the return hose at the FEL connection is connected to is proper place.
This just happened last week and I have my whole tractor disassembled right now looking for this issue.
Tractor will move forward and backward just fine.
When attempting to operate the 3 pt lever it sounds like the 3 pt. does not disengage when it reaches the top and appears to be bogging down the motor.
Could shut it off and it would return to normal but, not that stopped and appears to be engaged all the time.
Have tried different throttle positions and no change. I also hear what sounds like air blowing out near the trans while in this state but, cannot locate it as I have bad hearing.
I change the fluids twice a year whether it needs it or not so there is fresh hydraulic fluid in the trans.
Kid was mowing last weekend and he noticed that the trans was smoking, yes, changed the oil right after is cooled down.
Have not reconnected the FEL to see if that functions properly and now that the tractor is in pieces in my garage that won't happen for a bit.
looking for suggestions so I do not have to take this thing to the dealer as you all know these baby's are expensive to repair at home and 10 times as much to repair at the dealer.
Oh, no leaks in the system as far a hydraulic oil is concerned.
Very perplexed!

Any filters in this system? Not plugged up?
Does this apply to your tractor? one relief valve under the seat at pressure block, It looked as though the pump needed to be replaced after reading the function of the loader control valve it said that near the inlet valve there is a relief cartdiage sure enough a small piece of gunk had stuck this valve partialy open, by pushing down with a small bolt it broke free and move freely aginst the spring load screwed it back in and to my relief the relief worked and all was back to normal

I just replaced all filters for the hydraulic system a month ago and have had no issues until last weekend. Replace filter again after the incident.
I also removed the valve body for the 3pt and made sure that is was moving properly and it appeared that is was so I reinstalled it. same issue. Will raise once and go down but the load on the motor doe snot go away when lowering the 3pt. If the motor is shut off for a while and the tractor is restarted the 3 pt will go up and down one time and then the motor is again loaded from the 3pt until I shut it off again. Still confused.
