Update on my kobota back hoe. I ordered the pump you suggested JJ, and mounted it to my 13 hp engine, then removed the busted section of hydraulic valve and made 1 1/2 spacers out of steel tubing from tractor supply, put the valve back together, drilled two new holes for the mount of the valve where it was shorter and it worked great. Bought two 12" casters I am going to mount to the front of the hoe so the gravely does'nt have to lift it up, all it will have to do is tow it and it should articulate well. Now just need to get a single spool valve with pb and hose it in for the swing cylinders.
