We have a Kubota BX25 subcompact tractor outside with the backhoe attachment. A couple of days ago my father-in-law busted a hose on the backhoe and lost alot of hydraulic fluid. This isn't the first time we have busted a hose on the backhoe (first time I did it and shut it off immediately, repaired it where it was sitting, bled line, worked just fine). Well, he decided to drive it around a bunch after he busted the hose, near the bottom of the implement. There is fluid all over the driveway and yard. So, when he finally stoppedd, we went to town and got a hose and replaced it. Toppped off with hydraulic fluid, and cannot get the air out of the front bucket and the backhoe. They wont move at all, not even the stabilizers on the backhoe. We could be doing it wrong, but the last time I broke a hose, after I put the new hose on, I took it loose near the cylinder on the backhoe arm and worked the lever until fluid squirted out of the hose, then I hooked it back up. Well, doing that doesn't even get fluid to drip out of the hoses. I'm afraid hes broken something bigger. Now, the drive system is hydrostatic and the tractor will move forward and backward just fine. The scoop and backhoe just wont do anything. What could be wrong? Im an amature when it comes to hydraulics.
You don't have to take a hyd line loose to bleed air out. Just working the system and the air bleeds itself.
How long have you let it run trying to get everything to work? I have seen times when a hyd system was completely drained it would take 5 to 10 minutes of running for the fluid to get back in the system and things start to work. For example, when I did the 50hr service on my first M9000 the steering didn't work when I started it back up. I had to let it run at low idle for almost 10 minutes and then everything was fine. Good luck and let us know how things turn out.
