Loader Hydraulics Dead

[Rch]

If there is water in the transmission/hydraulic case (check boot and shift-lever gasket as it enters the transmission) and it got cold enough water may have froze in the h-fluid return circuit or other low point. Also check transmission breather valve,typically on the top of the transmission/differential case, as a h2o entry point.

It is so true about people playing with levers and knobs. My son was on the tractor while it was in the garage and he closed the valve for the 3pt hydraulics. When I tried to operate the hitch, it wouldn't move. Took me several hours of looking at everything BUT the shut off valve, before I figured it out /w3tcompact/icons/blush.gif. Did you try bleeding the system? Could entrained air be the problem? Just a thought.

Bingo, I am back in business. KCB you were right, and so was Bird and others who said look for something simple. My 2150 has a "directional valve" on the right side of the frame which feeds either front and rear hydraulics, or just the rear. It has a very thin metal stop so that it is either all the way clockwise or all the way counter cw. The stop was bent over and not stopping, and the placard discribing the function of the hex shaped valve handle is faded and scratched up, can barely read it.

But when I did, I followed the directions, and sure enough my pant leg had turned the valve so that the hydraulics were shut off to the loader! It's good to be back in business so easily. This was a good lesson for me. Thanks for the good advice.

You were right Bird, it was simple. Had inadvertantly turned off the hydraulics directional valve to the loader. But now that that is fixed, my float doesn't seem to be working. When I push forward on the stick the bucket just goes down, and it seems like the harder I push it the faster it goes down. Can't feel any detent position and I've pushed forward so hard that it feels like I'm about to break something....and my front wheels are off the ground!

What am I doing wrong? The control stick placard shows a position for float so I think it should be there. maybe something is stuck?

Glad it was simple. And I learned something, too. I didn't know that tractor had such a valve.

Well, we almost entered messages at the same time. Maybe there's something different about your loader valve that I don't know, or maybe something's stuck, but every loader I've used (and that's not a large number) had the float position. If you push the stick forward and lift the front wheels, then push past that detent and the front wheels will drop back to the ground. Is there any kind of obstruction preventing the lever from going all the way forward? Sounds to me like there either has to be an obstruction preventing the lever from going forward far enough, or something has to be stuck. I don't know what the experts would recommend, but I'd probably spray a little WD-40 on the rods where they go into the valve and try again. That worked for me once when I had one that didn't want to go into the float position.

My Kubota has a little hinged plate that restricts the control lever motion. It is right on top of the control box and very easy to see. I asked the dealer what it was for and he said that it was of no use, and I agree with him./w3tcompact/icons/smile.gif

 

[fredoroberts]

Yea, I have one of those too. I think it is intended to stop someone from fooling around with the controls, but mine is so loose that it doesn't restrict the control enough to stop it from moving the bucket. I will check and see if it is obstructing the movement into float. Might just take it off anyway as it provides a false sense of security.

My B7100 didn't have one of those hinged, spring loaded, notched plates, but when the B2710 was delivered, I too, asked the salesman what that was for and he didn't know either. The picture in the manual shows it, but does not label or name it or say anything about why it's there. I thought about taking it off, but haven't. So far, the spring holds it up out of the way, and then I pull it down around the joystick when I remove the loader just so I won't accidentally be moving the stick around (which I don't suppose would hurt anything if I did move it around).

fred - did you have float before the valve incident? If not, I bet the ball and spring that holds the valve spool in the float position is rusted away. It is an easy fix. to read all about it and WAY MORE go to archives and find a post I did called "loader S-L-O-W in the cold". You will find how to fix it. If you have trouble, post again or email me.
