Have a Bradco 9hd backhoe from a skid loader that we mounted to our WD45. Tractor has an old PTO hydro pump, seems to work well.
Problem is that there doesn't seem to be enough pressure for the backhoe. The stabilizers won't completely lift the tractor off the ground. Loader has 20 gallons of fluid in it and almost all the lines are new. From the pump it goes to the relief valve which is directly threaded into the diverter valve. I took the relief valve apart (ball/spring type) and it had already been threaded in the entire way. And the backhoe has a new filter.
I was told that the backhoe is most likely a closed loop type. And the tractor being an open loop as the return just dumps unrestricted into the reservoir. Anyone know if that could be the problem? Loader and hoe are plenty fast. The loader will lift about 1500# and when the bucket its tilted down it easily lifts the front of the tractor off the ground at idle. Have only tested the backhoe's functions as we are not quite done with the mount yet.
