190xt won't lift disc mower

My 190 xt will only lift my 10ft disc mower about 4in, on the 3 pt and the same on the cutter bar. Ive tried turning the relief valve up a little and no help. Have good pressure, just wont lift. Help!!!

where is this flow divider???

I assume you already checked to make sure you had plenty of hydraulic fluid in the torque tube.   Mike

Under the torque tube. Has a drain plug in the center of it. It's the humdinger that the 2 bigger metal tubes bolt to on both sides of the bottom of the torque tube. You can buy a 5,000 lb. Hydraulic gauge for around $35. And check the pressure at the remotes.

"Pretty good pressure" and "I tried turning up the relief valve a little" ?? Those are really funny statements for a guy who doesn't have a pressure gauge!!! Keep goofing around like that and you may have a hydraulic pump body split wide open. Just because you think the tractor should be able to lift this mower easily, doesn't mean you aren't exceeding the weight capabilities of the 3 pt hitch. Locating the top link in the top hole on the tractor is one way of increasing the hitches lifting power. The bottom hole reduces the lifting power. GET A 3,000 PSI GAUGE AND PLUG INTO A REMOTE OUTLET.

100 psi is a lot of pressure when you loosen a line, but 100 psi won't lift the lift arms. Like others have said, you don't know the pressure until you put a gauge on it.   MACK

Have you used the tractor to lift/raise the mower/cutter bar before? If you have before then I would say you have developed an issue. If not, a 10ft disc mower is a heavy SOB. You might be asking a bit much of your tractor.

You don't take directions very good. The suction screen isn't your problem. Yes, you have to drain all the hyd oil to clean the screen, which isn't your problem. You might have a pressure problem (and you might not) and that is only verified with a 3,000 psi gauge plugged into a remote outlet and pulling/pushing on a lever to activate the hydraulics. You didn't answer the question as to whether or not you've ever picked this implement up before, or if this is the first time for this tractor and implement. You need 2,200 to 2,400 psi at the gauge.

Ouch. That attitude won't help you much. Dr Allis isn't some Jonny come lately, he's a darn smart guy who is trying to help. Remember the fly & honey deal.

All I can say is good luck.

No one should ever talk that way to the Dr! He said nothing to disrespect you. He only suggested you do one thing, and you persist on doing another. He's an expert for a reason. He's one of the top 5 smartest guys on here, as far as I'm concerned. Seems he always has an answer to everything related to big machinery, whether it be a One-Ninety not lifting, a 7080 not moving, or a Gleaner L3 with air in the steering lines.

All I can say is good luck. All true. However, "You don't take directions very well" sounds pretty insulting, whether meant that way or not. Everybody can be grumpy at times.

As I stated, i do not have the gauge currently. I figured I'd go a head and check what i could with what i have. Seemed logical but apparently not.

As stated earlier by others, without a gauge you are playing with fire by adjusting the relief valve at all and could end up splitting the pump. $2,000 buys you a new aftermarket pump and $700 might buy you a well used one. If it's that critical to get going right now you may have to hire or rent.

JDodds, Here is the deal from my perspective of being here for 18 years commenting and watching... Doc is a busy man, like said, he has been down this road many times... and should be glad that he is willing to help and give his expertise.  When he asks questions and from the man that has troubles, he needs the answers to help pinpoint the cause.
 Not picking on you singled out, because many times over the years I have seen that happen, somebody asks for help, then the fellow that tries to help asks questions  and then the one needing help disregards answering the questions and makes some other question or statement.  To answer the doc, the least you could have done was to say, "I have a gauge coming" some where in your reply and he would have taken that into consideration and he might not have had the answer he gave.
  My 190XT lifts a 12 ft. moco and has plenty of hydraulics to do it. and the 190 gas will lift a 1327 disbine with the same ease.
  Question is when you are lifting the discbine or the 3pt, and it does not lift, do you hear any reliief valve squeel?
