My tractor is set up differently than the rest of the videos on the poor man's power steering that I have seen. This video may help you if you are interested in doing this and the other videos don't help you.
As an update to the video, I mowed this morning, and it is quite a bit easier to steer on the grass. On concrete or asphalt, it isn't as easy, but still easier. I am completely happy with the upgrade.
