Kubota m7060 loader hydraulic problems, need help diagnosing.

[Jrasband]

Hey guys, hoping y'all can help so I can figure out next step. Something got messed up on the tractor when I cleaning up a down pine tree on my fence line. I think it is likely not going to get covered under warranty so I want to try and fix it myself. If there is significant(expensive) damage I may make a insurance claim unless it's possible Kubota will warranty it.

At first I pushed down and stomped what had snapped and fell on the fence. Than I tried to push down what was left standing. I briefly had the front wheels off the ground. I think what happened that caused damage was : The tractor forks slid off what I was pushing on, and got caught on another branch before the front wheels hit the ground.

Now I have lost 90+% of forward(retract lift cylinders) function on the joystick. I can still float and push the joystick forward to make the loader drop. Pulling back on the joystick(extend lift) seems to have full hydraulic pressure, but stops when the loader gets about six feet off the ground and will not go another inch. Doing multiple functions on joystick does not make any difference. Will not go past 6' and will not retract cylinders under pressure. When I push joystick forward the pump sounds as if it is deadheading immediately.

There are no visible obstructions preventing the loader from going to full height. The loader is still straight and is not racked as far as I can tell. What do you guys think is going on here?

Turn the engine off, move the joystick around to relieve any of the pressure, then go inspect the quick disconnects for the loader hoses. I'm thinking one of those popped out.

Don't limit yourself to look at the hoses, try to move them around with your hands and see if one of those is not fully seated.

That would be a big relief if that is all that is wrong.

Good catch. I read through Jrasband's description of the problem - which seemed pretty complete. What was it in that description that gave you the clue? Whatever it was, I missed it.

For me, it was the environment the tractor was in (brush, branches, etc) and the description where the OP said the cylinders would only move a couple of inches and then stop.

Ptsg I’ll just have to say you took advantage of all the clues. I enjoyed that one. And hats off to jarsband, he layed out a good problem with some pertnant clues. Great teamwork
