[AT] spring tooth harrows

[John Hall]

For you "older" guys, why did you run spring tooth harrows? What 
implement replaced/obsoleted them? I've got one, haven't used it in 20 
years. Not sure it ever did anything but burn fuel.  When I was a 
teenager we would run a section harrow behind the offset disc harrow if 
we were trying to break up clods, level furrows, knock the dirt off 
roots, etc. Just wondering what good a spring tooth harrow was/is. Yes I 
know it will choke up in trashy ground, and pull hard if you set the 
teeth way down.
