I have a John Deer 4044M equipped with third function which I use for operating a grapple. The lines attach at the rear of the tractor and I have the rocker switch mounted on the joy stick to open and close the grapple jaws. All John Deere equipment. I am looking at purchasing a loader arm mounted brush cutter with a hydraulic motor matched to my auxiliary hydraulic flow. What do I need to do to in order get continuous flow to that implement ? Do I need additional rear remotes ?
