hydraulics don't work right.. guess the pressure goes into the far side of the backhoe valve body, then halfway through there is a block that goes to the loader valve body, then at the end of the backhoe valve body, there is whats called a return valve.. somethings messed up because its trying to send all the fluid through the middle block to the loader,,, the first valve blocks (before the middle) the backhoe will function,,, maybe even the stabilizer arm seems full functioning, then the next two will move enough to pick itself off the ground but not have working power, UNLESS, you pull up on the loader bucket control,(move the bucket up) then at the same time the backhoe has more power... The control furthest to the right on the backhoe-the stabilizer,, has very little power.. gotta be sumthin messed up,, either in that middle block or the furthest return I would think. I removed a plug,, then a spring with a ball from the bottom of the center valve,, wasn't a cure,, been trying to do the same with the furthest return,, haven't got that out yet, may try again today,, or else the return is jacked up some how from the backhoe valve to the tank, the return filter in the tank was junked up pretty good,, I cleaned on it, soaked it in kerosene for a few days, then blew it out and replaced it, will get a new one if I can get the system up and goin.. thanx Steve
