Ford/New Holland 2120 Rear Hydraulics

T4R11 · Apr 1, 2023

I am trying to add a two spool valve to enable rear hydraulics for a hydraulic top link and hydraulic leveler/tilt on a Ford/New Holland 2120. The two spool valve(s) I have are mounted on a plate with 3 ports... IN, OUT and PB. My tractor has a front end loader valve with 7 hoses - 4 smaller hoses control the bucket function. The other three are larger and are connected to a combination system relief and manifold valve. These three include...high pressure from the manifold valve to the loader valve, return to reservoir and return from (loader valve) to HPL port. If:

(1) I connect the return from loader valve (in bold bold above) and connect it to my new two spool valve IN port AND
(2) Connect the OUT port on the new two spool valve to return to reservoir AND
(3) Connect the PB port on the new two spool valve to the return from (loader valve) to HPL port on the combination system relief and manifold

Would this work? If not, any suggestions on an alternative way?

Summit has good pictures on their site. Which give you good direction. And, what you’re proposing should work.

I’m in the process of gathering parts to do the same thing on mine with a second cable actuated loader valve and a second joystick.

Power Beyond from the FEL valve to the Pressure port of the new rear valve. A1 & B1 to the top cylinder, A2&B2 to the side link. Debating whether to add a diverter to both circuits for rear equipment. Will probably wait until I actually have rear implements which need hydraulic controls. But, I spent a bit extra to get a two button joystick to make it lots easier.
