Adding a 3rd function valve to NH Workmaster 55

Thanks for all of the info J_J. Much appreciated. Any idea on where to find instructions/how-to on installing the valve you recommended?

Here are three videos for installation of a 3 function valve.

I am looking to install a grapple on my existing bucket & found this thread searching 3rd function. Thanks for the links for the 3-part installation, it's even my exact tractor.

I'm not as well versed in hydraulics as I would like, but near as I could tell the kit in the video use this solenoid valve: D03S-2B-12D-35 - 12 Volt DC

Is the configuration correct? The rest of the kit looks like a few bracket, the knob/switch & some hoses. Am I missing something?

Thanks, TD

No, that is a closed center spool.

Need something like this.

12 VDC 10 GPM OC DA SOLENOID VALVE

1 STATION DO3 SUBPLATE OPEN CENTER

JJ, Thanks for your reply.

I knew I needed the open center but didn't pay close enough attention to the actual valve schematic.

Will work on a parts list in the meantime but will most likely fabricate my own switch set-up for the loader control lever.

Thanks, TD

You might even consider a two pole switch that will lock the grapple on in one position, and momentary position for momentary use.
