Hi everyone!
I'm working on my father's Kubota BX25DLB, and I am hoping I can ask some advice about how to fix the 4in1 bucket which has stopped working. All other hydraulic functions appear to work fine. Relevant background below. :
1. He absolutely loves his little orange tractor and recently did some work grading his driveway, which is when the 4in1 bucket grapple function stopped working.
2. All other hydraulic functions work fine.
3. His model has a Kubota 1200mm 4in1 Bucket with a front control loader with two buttons to operate the grapple function. Pressing these buttons no longer work to open or close the bucket.
4. I researched what to do, and thought maybe he accidentally disconnected the hoses partially (apparently this can happen) ... I disconnected and connected the hydraulic lines several times, but it didn't fix it.
5. I disconnected the hydraulic line at the 4in1 bucket in case it was locked up, and bled the line ... nothing wrong with the hydraulic piston. It can be manually opened and closed by hand (heavy though) ... so I don't think he backdragged it and broke that part. It appears to be lack of flow into the hydraulic hose. Not sure if have to flush the air out after reconnecting. I did top up the hydraulic oil reservoir and ran the machine in neutral and exercised all the bucket boom lift functions ...
6. I used a multimeter to test the switches worked for the grapple function. They appear to have continuity so the switches work mechanically to shunt signal. I redid the electrical lines to the front control valve assembly thing... I think the wires are not the problem.
Not sure about the power or signal or where it goes ... all I know is that a ground wire comes from under the engine cover and goes up the lever stalk where there is a left and right button, and each of those signal wires go into the pictured front loader control valve box thing. I actually am not sure what it is.
I am kind of stumped. I'm handy but not a hydraulic expert and first time tractor owner. I would be grateful if anyone help advise me of a few ideas to figure out what is going on? The unit only has 350 hours, and has been babied until recently when we acquired it second hand. My father might have been a bit rough as he is still learning to use it. I am keen to learn how to fix it myself. I have looked over the WSM and the Operator Manual but I am not sure what to do at this point ...
