Ok, I admit I am confused. I just purchased a Shaver HD-10H used that had been used on the front of a Bobcat. Yesterday while finishing up on converting the skid steer mount to a 3-point mount I noticed 3 hoses with ends on them. All the manuals and pics only show two. One for pressure and the bigger one for return. I looked a little deeper and there seems to be some sort of hydraulic device mounted on the base plate under the control valve assembly. I am working from memory here as I don't have it in front of me at the moment. I think the odd (3rd) line (pressure) goes into this diverter manifold looking thing and one output goes to the control valve also.
It appears to be a factory installation but I could be wrong. Why would a third hose be used on a Bobcat? We know one is pressure and one a return. So, what is the third?
Thanks for any help.
