[QUOTE="ytr1903, post: 12873, member: 667"] The Bradco 9HD operates off a Bobcat. Last fall the backhoe attachment worked perfectly. Now only the stabilizer arms operate correctly. Both of them will go up and down and will maintain their position overnight with the Bobcat’s weight on them. No other functions operate, though. They all seem to want to operate and will move slightly and then will stop their movement. It seems as if there is not enough pressure in the system. I'm guessing that the stabilizer arms don't need very much pressure and that is why they are working.There is hydraulic fluid coming out of what looks like a relief tube/overflow tube down to the ground, when the hydraulics are turned on from the bobcat. I checked and cleaned the inline filter, but there was no apparent clogging in the filter, and it made no difference in the performance of the backhoe. When I turn on the hydraulics of the Bobcat, I can see the hydraulic hoses jump, just as I can see the hoses move as I operate the the backhoe controls. The bobcat itself works perfectly and I have no reason to believe that it is not producing enough hydraulic pressure. My skills with hydraulics are in their infancy and any suggestions as to what the problem may be would be appreciated. Tom [/QUOTE]
