i have an agracat 2920 believe it is a 2005 and i'm having problems with the 3 pt hitch. it doesnt lift up at all and it will fill the rear housing with hydraulic fluid and it will start to drip out of the vent tube. when i check it after it has sit for a while there is nothing on the dipstick. like it can pump into it but it isnt able to suck fluid out of the 3pt hitch. do i have a stuck valve? any help or advice would be awesome! thanks

Probably not too complicated, but a little more clarification will help.

If I read it right, you fill the differential up to the proper level, then after it has sat a while, the level is too low. Is that correct?

If so, is there a leak somewhere, or just the fluid coming out of the vent tube?

If it's just coming out of the vent tube, explain the conditions under which it comes out, running? parked? running but only when the 3pth is used?

Finally, have you had the tractor long? Is this a new problem?

Best of luck. ....

Seriously though, it sounds to me like MAYBE the 3-pt cylinder has blown a seal or cracked and is dumping the oil into the rear diff. It can't return fast enough to the pickup tube (restricted drain-through holes?) and therefore has to go somewhere--out the vent tube.

I'm jis' sayin' ....

OP asked question in more than one forum. Issue is being addressed in Chinese tractor forum.
