I'm pretty new to this, but I'm stumped. Yesterday a friend was using my BX2200 (which I just bought). He raised the FEL pretty high and lowered the scraper attached to the 3 point hitch at the same time. The engine got really rough and rattled, then died. This happened a couple of times for the next few minutes, then I just shut it down, lowered the FEL and then it started right up. I ran it around and operated the hydraulics several times. No further problem. Anyone know what would cause it? Is it using both at the same time? Just want to avoid future problems. Thanks
Engine ran rough when hydraulics engaged

It is probably not a hydraulic issue. The engine is plenty strong enough to run the small hydraulic pump. The pump will go into relief and whine if it is overloaded.
The problem is probably fuel related. Since the tractor is new to you, you might consider changing the two in-line fuel filters unless the prior owner assured you he/she did it. (Other service issues may also need to be addressed as well.)
For one of the fuel filters you have to remove the engine cowl (just a few screws) and the other is underneath the center of the tractor.
Use vice grips or something similar to pinch the line and cut off the fuel flow from the tank. The filters are simple plastic in-line types. But they aren't cheap.

I too thing it is fuel related, GWD gave excellent advice. The filter that is under the deck is the one that catches all the crap....like he said, there are two, one before the fuel pump and on before the engine.....
do a search on how to purge the air out....it is here somewhere, paul - wildfire has a nice video on it too.
Following up for anyone else who may have the problem. Had a discussion with the local Kubota dealer. It apparently happened because the FEL and was engaged while the scraper (3point hitch) was in detent, causing the two to fight against each other. I'm no mechanic, but that makes sense to me. It only happened when both were engaged at the same time.
First, see if you can duplicate the occurrence. That would verify what the dealer told you and your tractor problems are over for now.
The dealer is basically saying that it is "operator error". This is a common excuse for when a dealer somehow screws up and wants to cover his/her behind.
However, it is my experience that if the FEL and the 3PH are "fighting against each other" then one of the two functions will not work or will tend to be jerky.
Once again, the engine in the BX is not going to die because of the hydraulic pump being balky.
Try crawling under the tractor with a flashlight and check the filter that is there. It is opaque plastic so the element should be clean if it was recently changed. If the element is dark then something is amiss.

The filter could have not been changed or the fuel is contaminated and dirty.
I hate to be negative but the dealer's explanation just doesn't add up. I've operated my BX often in those circumstances (rear in relief and FEL in use) and it has never coughed or died.

Got some good additional info :
What the dealer is explaining is that as the pressurized fluid is filling the "lifting" side of the loader cylinder (to lift the bucket), it needs to "vent" fluid from the "lowering" side of the cylinders. That fluid goes downstream through your rear remotes (if equipped) then through the 3 point valve, then into the tank.
If the lever for the 3 point lever is in "raise" position and the 3 point is all the way up, the only way for the fluid to get to the tank is by getting to 2000ish PSI and going through the relief valve.
That causes the loader and the 3 point to "fight" each other.
Note: This should ONLY happen if you are trying to move the loader and the 3 point at the same time.
I agree with all the advice given to you by GWD and 85Hokie but not with the info given by your dealer. If a 22 hp Diesel engine can not overcome a small hydraulic pump with " 2000ish PSI and going through the relief valve", there is something wrong with the engine or another component.
If you put a load in the bucket of the FEL that is heavier than the tractor can lift, the the relief valve will open allowing fluid to bypass.
Obviously, this is just my opinion.
