I have the SpeeCo PHD that I bought from TSC with a 9" auger. It's been about a year since I last used it, but am planning to do so again this weekend (if the weather holds out). I seem to recall that I used the hole closest to the tractor to give it more height. The PHD main post hits the plastic body cover at full lift hight. The middle hole would allow the auger to drag, just a bit.
I don't find it to be too difficult to hook it up, I've done it by myself several times. I do remove the auger each time.
I seem to recall when looking for PHD's that I a saw a stand offered by one manufacturer. There was a picture on their website. Might be a good starting place to give you ideas to build your own.
