I purchased a Ford 7000 a couple of months ago to use as a second haying tractor. I have since added a loader. I'd like to add a grapple to the loader and was wondering if the load monitor couplers can be used to operate the grapple. My set up is this, I have a single spool vale with 1 set of couplers coming out and then the second set of couplers, for the load monitor. There are to knobs on the lower right side just below the single spool vavle. So, can the load monitor couplers be used to do this or would i have to buy a dual spool valve?
