Test your cylinders on the backhoe, if you have a cylinder leaking past the piston in the cylinder, you will have weak and slow operation. To test, disconnect one line from the cylinder, plug this line, use the hydralic's on the tractor to bottom out the cylinder, if oil comes out of the connection where you disconnected the line, the cylinder needs rebuilding, if no leak, hook the line back up and disconnect the other line and use the same procedure above and test this side , you may have some leakage, but not excessive when you pressurize thru the cylinder to the piston, leakage will be caused by bad packing and 'o' rings. What diameter are the cylinders, on the loader and the backhoe, if the cylinders on the loader are large diameter, you may not have problems on the loader, except being slow, but it will lift any thing you want to. Test all the cylinders, most people will have all cylinders rebuilt, when only one is leaking, this will save you some money.
