Keep in mind that there is no pressure relief built into the system to prevent overload on the hoses and cylinders that are downstream of the loader valve if the loader valve is centered. When the valve is centered, it prevents oil from going back into the system. It is trapped, and that isn't a problem unless you have a big old stout tractor and you push hard with it against a tree or something. Pressure builds way high, and things bend, break or burst. This is different than when you are lifting a huge load and are applying maximum hydraulic pressure from the tractor. It only applies so much, lets say 2600 psi, and bypasses to the tank any excess pressure.
I pushed a bunch of trees over last Saturday with my skid-loader, but when I did I made sure I had the bucket pretty much perpendicular to the tree trunk so as to not load up the tilt cylinders and I did not lift much as I pushed, as that gives you incredible traction and if the tree does not go over and if you do not lose traction, something must bend, brake or burst. I've bent and broke a few things learning this....
Sounds like the 8560 is serving you well. Thanks for the positive report. And be glad the hose burst, that is a cheaper "fuse" than anything else in the system. It would be nice to have a load relief beyond the valve, but I do not know of any farm tractors that do that. In theory, the front loader on a farm tractor is made to load, not dig or bulldoze. Commercial equipment can have reliefs for shock loads downstream of the valve.
