I have 2012 Kubota MX5100 hydro with a LA844 loader. Suddenly it began experiencing loader issues. The curl or roll function works as it always did. It raises very slowly but will pick up a bale of hay. It has no down pressure even with a bale on it. The only way I can get the thing to lower is to shove the leaver into the float position. I tried reversing then quick connections the curl seemed to function but the loader would only raise when no matter how I moved the control leaver. Any suggestions?

sounds like a cylinder issue to me, you have either the packing blew out past the gland or a gland that has come loose and is floating around,, may not be it but this is what I ahve seen cause issues like this over the years

Easiest way is to just pull them apart if one needs resealed/ repaired the other does also as it moves just as much as the other, you could do hook up one cylinder at a time and see if it works but to me thats harder than just pulling a cylinder down, I think I read where you said you switched hoses to the bucket circuit and the lift still would not work,, that is why I did not bring up couplers as you already ruled that out

Go back to your 3 point lift lever and move it forward about an inch . You have something like a box blade on the back and have raised the lift lever too high. You have you tractor in the constant pump position, check your operators manual. If this is not the problem then like the other posters you may have a quick cupper that is not fastened but most time it is the position of the lift lever as stated above. please post back what you find
Up date: I took all the quick connections off connected them together, all were clear. I disconnected the lift cylinders one at a time and capped the lines, no change on either cylinder. The symptoms of raising slowly and not lowering unless I went to the float position continued. Yesterday I was moving some equipment and in a tight position and had to raise the loader to clear some some fence and it was working as normal. It even lowers and raised the front end off the ground. Here is what I think: the weather was cold when this began in the teens at night 40 during the day and it was in the mid 60 yesterday. It had a restriction in the cylinder raise side either in the valve or supply side. It would allow just enough flow to slowly raise the arms. The lower function because of the less surface area could not over come the larger area of the raise function unless I went into float. The thought of that much moisture in the hydraulic system scares me. I have owned the tractor for 3 years and it was quote serviced before I bought it and is shedded all the time. Your thoughts and comments.
