I have a two year old 1025r. The left backhoe lever has been sticky from the start - making an audible sound of rubbing from inside the valve. The boom in/out would not return to "neutral" when released. After two attempts at adjusting the linkage, the dealer replaced the complete valve assembly. It was still sticky. They ordered another new valve (very expensive) and replaced it again. Still not as it should be, but I lived with it.
However, after a year with this new valve it has slowly gotten worse. Now the swing left/right is sticky as well. The right lever has always worked great. It only swings right very slowly now, and sticks there - sometimes leaking so slowly I don't even know it is stuck until a couple of minutes later and it has swung all the way right. Of course that is sucking power from other motions - and terrible for the pump.
It's so bad now, it is dangerous to work with. I try lifting/digging something too heavy and the tractor starts to tilt so I release the lever and the tractor continues to tilt.
I've never taken the backhoe off. But I've watched how to do it and wish to do it soon. It would just be impossible to do it safely the way the levers stick.
Can anyone give me (and the dealer) some advice as to why this seems to be impossible to fix? I'm hoping someone may have heard or discovered something in the 1 1/2 years since I asked this question a while back.
