My Kubota SVL 75-2 operates fine until it is good and warmed up, then the boom and bucket will barley move. Fluid is clear, level is good, and the filter was just change. 3100 hours on the machine. I have talked with several Kubota shops and they all tell me they have never heard of such a problem like this. Just bring it on in and we will get you fixed is what they say. I wish that money grew on trees so I could pay them to fix it.
