Okay, without the rear remotes, one has hoses running from the power beyond outlet on the main valve body. A lever must be turned to allow flow to the power beyond when the backhoe is hooked up.
Putting on the rear remotes, with the lever next to the 3pt hitch, the flow of the fluid is now operated with the lever, not the diverter on the main valve body. No more hunching down to turn the lever on and off.
If I have this right, you're going to put on the Woods hose kit and run it to rear remotes, bypassing again the need for the diverter of the power beyond. Correct?
I have mine running of the PB with hoses running back through the tractor where I then hook up the backhoe and move the diverter lever on my main valve body. A much easier location to access on the CK20. I don't have rear remotes.
