Hello!

I'm taking a look at a case 580SM, but I've got no reference material for the thing. Anyone have the hydraulic schematics?

Loader function is good, but the hoe has no power. Pressures are 2800 psi for the loader, and 1800 for the hoe(all functions). I can't even find the relief for the hoe block, and I'm not familiar with case at all.

thanks for any help
