I bought a 1974 4500 industrial. It has a loader , 3 pt. pto. No backhoe. I want to add remote hydraulics to operate equipment from the rear of the tractor. Things like a wagon hoist, wood splitter etc. How do I do this?
One way to do it is to install a selector valve onto your hyd top cover. there should be a plank plate about the size of an index card there right now, held down with 4 bolts... it is: C5NN475B COVER Cover Assy., Accessory, Replaces C5NN475A, Except 4200, Includes: Ref. 14 thru 18, Start Year: 01/01/1965
The selector plate diverts hyd pressure from the 3pt to it's port. from there you could plumb it to a couple Open center DA dalves that were setup with detents, and QD's, and then plumb a return line back to your hyd sump. many people remove the hyd sump cap, and drill/tap it for a fitting and use a low press hose for the return line from the valve to the tank sump/cap.
The fact that yours is an industrial slightly limits your options... The regular thousand and newer series IE X000 and X600 have options for mounting a single or dual DA valve right there on the cover, without any extra plumbing.. just run t he hoses back to the QD's and that's it.
Check your hyd top cover.. you may already have the selector valve there.. setting unused.
