Sorry Jack I was away for a few days.....As far as I know the loader valve has a power beyond port straight from the factory and I can't think of any "kit" he may be talking about. The only thing I think he may be reffering to is a seperate valve you can mount in the vicinity of the loader valve which taps off of the power beyond port on the loader valve. This is what you would use to run the power angle on the plow. With this set up you can tilt the blade fwd and back with the curl/dump circuit as well as angle your blade with the add on valve. You would have an extra valve and control seperate from the loader controls. This usually comes with the front blade kit if it is specified when ordering. However this will add to the price of the blade kit (not sure how much $$). I do know the price of the 4 pos valve is about 40 bucks higher than the 3 pos valve which will obviously save you money in the long run. I personally can't think of many advantages to having the ability to tilt your plow blade, but if you can, then this may justify the additional cost of the add on valve. Just a ballpark geuss, with the additional valve added on later you may be looking at 200 to 300 bucks more. Now keep in mind, this is the front blade kit that mounts to your loader assy. Most of the ones I have installed were supplied by Curtiss.
