I just purchased a used Legend 740 loader and am setting it up to run on my 7810. It came with a joystick and all the necessary connections, but is set up for a power beyond block, which I don't have installed on the tractor. My question is, do I really need to buy & install the PBY kit on the tractor or is it just as functional to have some hydraulic hoses built and use the SCV on the tractor?
