Thanks for the responce.
I have had to make adjustments to the loader valve when I first got this tractor, The way it was set up the bucket couldn't lift the tractor off the ground. I found the adjustment screw and gave it one turn at a time until it could do some work. Now when I have a load the engine will load up.
My backhoe will not load up the engine, in fact it is way to weak to do much of anything. I know that the problem is in the tractor relive valve and not the hoe because with the Hoe disconected the PBO valve when opened doesn't lug the engine, even at low idle there is no lug at all.
I have messed with relive valves on old tractors in the past, but I don't know wear to look on this TC33D

I am not sure what the difference is of an open center valve.
I know that it stacks in series with the 3pt valve.
It doesn't have it's own return line but deverted to the tractor case.

I need some help tracking down the relive valve on my TC33D, I have a Bush Hog Backhoe and it has no digging power. I belive the tractor has Alot of power to spair because the engine does not even begin to drag down when the hoe stalls. I want to know if anyone can recomend a solution.
Thanks Mark
