M6040 3 Point "Hemorrhaging"

Or so that's what I've been told it called. It's pretty obvious in the video what I mean. I don't have a clue what happened to the audio.

Hey y'all, the Kubota has recently started doing this. I don't guess it really hurts anything, but it does bother me, even though I don't really notice it while running the BH. I've had basically no issues with the tractor since I bought it, which is great, but I have no tractor troubleshooting skills either, especially the hydraulics. Friends and internet searches haven't helped either.


So just a run down, it didn't do it when I bought it. When I shut it off it would hold and implement indefinitely. Now it won't stay up even with the engine running. I did read that if a lift cylinder seal was leaking, you could close the lowering speed adjustment, and it would leak down. If it didn't leak down, the lift cylinder wasn't leaking. Well mine didn't leak down


It does it with the FEL on as well as off. No issues with the FEL holding up the tractor overnight. Hydraulic fluid isn't low, and doesn't look to be in bad shape. Hydraulic filters are new. FEL has come down jerky with the weight of the BH on the back, but only twice.


I haven't been able to find anything Kubota specific, and didn't find any solid answers on any other tractors either, cause I figure the principles would be the same. I don't really have any idea where to start, so any help would be greatly appreciated.


Thanks y'all

Dude. Wolfman. That will be a HUGE help to me. Thank you so much. I found the feedback lever. If it had any type of cotter key or pin holding it in, its gone so the lever was pretty loose. I have to work this weekend so I won't have time to try to get it straightened out this weekend. I'll let y'all know what I can get done on it Monday. Thanks y'all.

So I took the shop manual and get the feedback lever hooked back up and set to the factory length. It's still surging.

Also, it used to hold up for a days at a time, with a 6 foot tiller anyway. Now it leaks down overnight with nothing on it at all. Where do I start to find what's wrong?

10-4. I was hoping there was a way to nail down exactly what it was before I had to open it up. Thanks again y'all.

I agree. I try not to let things stay up. Not that it matters now. But I guess that's why the tiller stands out to me. I don't usually leave things up. Seeing that tiller up for a few days was out of the norm.

I tried the lowering speed knob off and it doesn't fall. So it seems like it will be the control valve. I'm not sure if I'll do it myself or take it to a shop. I read the WSM about the removal of the cover. It doesn't look to bad, but I'm leery of it because I've never messed with hydraulics.

Makes sense to me. I'll check it out Friday and report back.

This is frustrating. I was moving some hay yesterday. Put a spear on the back. Went to pick up a roll and I couldn't set it down. 3pt wouldn't do anything. Not up or down. Had to wrap a chain around the roll a drag it off the spear. 3 pt started working fine.

I tried it again on another roll just to make sure. Wouldn't do anything with weight on it. I cut the tractor off. And after a few minutes it just seemed to release and the 3pt fell, because I had it on the lowest setting. WSM says this is the control valve.

Ill check the lift cylinders like Wolfman said here in a little while.

ETA: Pulled off the clamped hoses. No fluid. Definitely is the control valve. Thanks for all the help and input. I'm probably gonna carry it to the Kubota place. I see this as something i could make worse by opening it up and messing with it.
