3-Point Hitch 3PH lifting arms not working

[Jay4200]

Well this did it. Thanks PADan. Turned the valve and the arms worked. The only problem is when I turn this to use the 3PH I can't use the loader. That's a little inconvenient. I will have to study it for a while to see if there is a way to fix it so I can use the loader and the 3 point.

Your solution is NOT a solution, unless a 3pt power-beyond run isn't plumbed into your tractor.

Generally, a valved function is a 3-terminal connection: input (pressure input), output (return to sump), and power-beyond (pressure line to the next function). Only the last function is two-terminal (input and return to sump), which is usually either 3pt hitch -OR- the backhoe. My guess is that you have only two lines going to the backhoe.

My tractor (Kubota L4200) comes with a hydraulic block that drives the 3pt hitch. Turning a valve on the block diverts closes off the flow to the hitch, diverting it to an outlet hose (which goes to the 'IN' terminal for my loader). The loader's power-beyond outlet then is either returned to the 3pt to run that, or went back to the lines for the backhoe, at which point the 3pt was disabled. A hose had to be manually swapped to change from one to the other. As such, I had a choice of running the rear PB lines, or the 3pt hitch - but not both.

I ended up running one additional line from the back of the tractor to the 3pt hitch input. That way, I have the original PB from the loader and return (to sump) lines, and a new PB line to the 3pt. Connecting the two PB lines together enables the 3pt. When I connect the backhoe, I leave the 3pt PB line unconnected (now the backhoe is last in line). Now, any additional remote valves (with 3 terminal connections) can be placed in the back to run other 3pt hitch stuff - there 'IN' port being powered by the PB line from the loader, their PB output going to the 3pt, and their 'OUT' port going to the return line.

Hi JayC,

Your presumption is correct, there are only two lines to the backhoe. Note that I do not have a solution, but an inconvenience to solve. Not sure what my solution may be. You seem to have figured it out. Maybe there is another type of valve block available for me?

I am open to suggtions.
