I bought a 2009 L5740 with 412 hours on in last weekend. I have been using the tractor about everyday with no issues at all. I was using the loader yesterday and all of the sudden I lost my hydraulics to the loader and the 3 pt. This is a 4 in 1 loader bucket. I have spent the day today going through the hydraulic components and I cannot seem to figure out what the issue is. I can get a little curl with the bucket and get the clamshell to open and shut. I cannot lift the loader or get the 3 pt. to lift. I am at a loss as to what could have happened so quickly to cause this. Any help would be great. I can drive the tractor just fine, my power steering works fine which I believe is ran off the same pump. I was thinking about replacing the suction filter and all the fluid just to rule that out, but it says the filters were all changed at 400 hours. Thanks in advance

One easy, simple thing to try is unplug your hydraulic quick disconnects to your loader, one by one, and reconnect them.
Sometimes they stay together, but are not connected.

Don't plug them in different locations, they are very specific which one goes where for ensure proper flow.
This happens on mine often when I am bush hogging in thick brush (really thick stuff). My quick connect for the power beyond gets unplugged and loader function and 3 point stop. Once in a while my loader flow return gets disconnected and when that happens I get a jerky loader response and no bucket curl/dump function.

Disconnect the quick connect fittings, make sure they are not dirty and reconnect them securely.
That brush will hit a quick disconnect ring and cause then fitting to break flow connection quickly, but many times they do not come all the way off and look connected even when they are not.
If it is the Power Beyond line that is not well connected, then yes. Hydraulic flow is from the Hydraulic distribution block, to the loader first then back to the hydro distribution through the power beyond to run the 3-point.
Yep, this freaked my out the first time as well. All I saw was dollar signs on what it was going to take to fix my hydraulics, then find out it was just a quick connect fitting...
You need to get your manual out and make sure you have the hoses connected to the correct mate. You can not just hook up the hoses and hope they are correct.
"I have tried un coupling all the hoses one by one. I have plugged them in different locations. None of that worked today."

I am not sure what your setup looks like. On mine, (L2950) I have three hoses that run from the hydro distribution block to my loader. My quick disconnect fittings are at the hydraulic block on the frame of the tractor.
You said you have switch up some of the fittings (how the hoses connect) just put them back where they belong and make sure they are all connected securely, wherever they may be located. Most Tractor hydraulics basically work in series (flowing to each control valve one after the other) so if there is a bad connection at one valve then it will affect other valves down stream of it.

My bet is that something is still not connected securely. Those quick connects can be funny sometimes and look connected when they aren't on all the way. Once you connected them, have you tried pulling on them to see if they will come loose without you pulling back on the ring?
Might try doing the steps you follow for removing the loader, "Hydraulic wise" which should eliminate the loader connections and then see if the 3pt will work. If it works you have a bad connection at the loader.
I keep watching this thread looking for the "Finally, it is working, must have touched that 15 times..." Thread.
It must be something simple.
If you are certain that the hoses are connected properly and the screw in the hydraulic block (if equipped) is set correctly for loader or non-loader operation and you still don't have hydraulics, then I might be looking to start testing hydraulic pressure. Maybe the relief is stuck open or you lost a pump.

Weasle,
Lets take a few steps back, one thing is that your tractor has a 2 stage pump, the PS and the PTO controls are off of one stage and the loader and three point are off another stage.
But the fact that you can get some movement out of the roll tells me that you are getting some flow.
Also your loader valve in integrated with the tractor so the PB is built in no hoses to become disconnected.
If the three point control is stuck in the up position the hydraulic system won't work right, this can happen via lever/valve or feed back rod/ valve.
Another more possible area that can just suddenly fail is the actual linkage to the loader valve, this will cause all kinds of issues.
I would look threw that very closely, The picture I've supplied below is only one of several versions depending on your exact model.
DO NOT just start diving into the relief valves, get the WSM for your tractor before you dive into any of the safety valves as one wrong adjustment on one can have seriously bad results for the whole system.
Also the odds of a relief valve just flat out failing are very very slim!
Three point lever linkage
Three point feed back linkage
Loader valve linkage
