hydraulics

you need a hydraulic valve.

i recommend a double spool valve.

it is available as an aftermarket item from TISCO or A&I for about $650. most tractors dealers sale TISCO and A&I aftermarket parts.

My mid-80's 1710 have a hydraulic manifold block that contains the diverter valve. Oil return from the auxiliary system goes back to the block and on the 3ph. Without the manifold, the 3ph doesn't operate unless the valve is manually returned to 'remote.' With this type hook-up, a power-beyond loader valve assembly is needed, and the 3ph will operate normally when no loader operation is active. A power-beyond valve has its own oil return line to the sump, and most tractors have an extra return port on the sump.

I imagine that most loaders are supplied with a valve assembly. Mine is an in-line set of three control valves, as opposed to a joystick. Generally it's a good idea to get a 3rd valve to provide valve controlled rear outlet since the expense is little more that a 2-valve assembly. Mounting the valve assembly is another question. Some joysticks valve assemblies are mounted on the loader frame, and the manufacturer probably supplies complete installation kits.
