I use a cat 0 drawbar with cat 1 pins from TSC on the lower links of my 3 point and attach the harrow with one of these. It won't spin. That extends it out far enough that I can easily see what is happening when making a turn, but not so far that the harrow will just sit there while the tractor is turning. You still have to be aware of what is going on behind you and in front of you, just like with any other implement.
