I used to have the hose kit and as you have found out, it will power the bh but you have to get under the tractor and turn the valve and then there goes the 3pt lift. If you disconnect the bh, make sure you turn the valve the other way or you are deadheading the fluid flow which is bad for the pump. The dealer suggested this to power my bh, it's cheaper, but I wish he would have told me about the remote kit which will still power the bh and give you full valve control from the tractor seat for anything you connect. And, the 3pt still operates. When you use the bh, there is a detent psition to hold the valve open. Around 4 years ago, the hose kit was @$125 and the rear remote was @$325. It's a few bucks to spend but worth the advantages you get. I installed mine but I did the dual set-up. It takes a few hours and the kit comes with instructions.
