Questions
I purchased a YFL-575 loader from a 155D and I'm having trouble finding and sort of schematics or even pictures to help me figure out how/where to connect the hydraulic lines. Assuming you did not get a loader with a separate pump (driven off the front PTO) then Yanmar intended for the B440 selector valve to be installed. The hydraulics are installed in series from the diverter block to the selector valve. You could use the loader or hitch, but not both.Reference
