Just started volunteering at a horse rescue and one of the projects I'm takin on is getting their 2630 up and running. Due to the cold weather this morning didn't see the actual problem but talked enough to narrow it down I think. The front loader has plenty of pressure so the pump should be fine. However, the rear frame mounted backhoe doesn't have any or at the least very minimum pressure. It appears the hydraulic lines go into a unit under the side of the seat which has an engagement level to activate the hydraulics for the backhoe. The lines run from here to a second box which is where the hoses from the backhoe actually connect. Hydraulic fluid runs out of this box when engaged. My guess is this is a pressure valve of some sort and has a bad o-ring. Could this box also be the cause of the no/low hydraulic pressure for the backhoe. (Sure wish I had thought of taking a picture when I was at the tractor.) Hopefully I've explained this well enough to get some help.
