Hydraulic releave valve

[BobQ]

I have a 4720, is there a releave valve on the tractor hydralic system? if so where is it located and what should it be set at? I would imagine it would be set higher than your loader or back hoe releave valve?

Thanks Bob

I ment relief valve! But I can't find a way to change it?

Thanks Bob

There is a relief valve under a cap at the backhoe valvebody but they are preset by Ameriquip, If you go up a few hundred PSI you can end up tripping off other Relief valves in the system like the loaders and the steering/hitch lift circuit of the tractor . On all compact backhoes the curl of the bucket is where most of your digging force is. Good luck
