Thanks Bill!
That's exactly what the person meant.  I've never heard them referred to that before.
Thanks for your reply!

[quote:339g0uyf]I think they might be referring to the semi-mounted plows first made in the 60's.  It had a mounting post up by the tractor and a long rod to the tail wheel.  when the tractor turned the rod would move the tail wheel and the plow would follow behind the tractor.

The first mounted plows were rigid and would swing very wide when the tractor turned at the end of the round.  This was not a problem with 2 or 3 bottom plows, but the 4, 5, and larger plows needed something to help them follow the tractor when turning and when plowing on the contour.

Hope this helps.
