Is it possible for the remote ram hydraulic valves on a series 4 d17 to cause the lift cylinders to not pickup any weight?

If I remember correctly, the flow is from left to right through the valve. So a remote activated will take all the flow. A left remote activated will disable either valve beyond it.

You can activate two( or three) levers at the same time, but oil will flow thru the one requiring the least pressure first and when that stroke is complete, oil will then flow to the second activated valve with a heavier load. Check your outlet pressure at any remote coupler. Should be 2,200 psi at full throttle when you hold a lever fully engaged for 15 seconds. The same relief valve controls the lift arms. Less than 2,200 psi will make lifting power weaker proportionally on both remotes and lift arms.

The system is called an open center hydraulic system. The priority is given to the 3pt lift circuit. ..and then to the inside remote ending with the left side remote. Take it from there...

anything else is ..well you can figure it out.. oh yes, I own a 175 which is identical to the series 4 D17 ..hydraulic/lift system wise...

With open center, there is no priority. Whichever requires the lower pressure will work.
On the D17 there is valve to adjust to change which works. Check the owners manual. If you don't have one, get one.
