I still have the Boss lift cylinder plumbed into the original system, but you don't need to use that when the plow is attached to the loader. If you set and leave the lift cylinder in "float" mode with the electronic controls, the plow will hang off the cylinder like a chain. You only have to set the cylinder in float once, then you can unplug the controller and put it way. Another option is to remove that lift cylinder completely and replace it with an actual chain.
Eventually I plan to fab up a frame/sub frame mount for the plow and operate both the side-to-side and lift cylinders with the loader controller. With the loader detached, of course. I'm mostly just interested in doing this just because I have extra Boss bush beam parts from my old plow truck and think it would be an interesting project to try.
