It's always interesting when you dig down and come across what some one did 
and left years ago. Farmers have a deserved reputation of reengineering on 
the spot. No criticism, it's a fact of life with these guys, it's what they 
have to do to keep running. What's amazing is that some of the band aids 
survive and work as well as they do. Reasons are varied, replacement parts 
availability, cost, Got to get it running NOW, What's on hand to fix it? 
But, you always wonder, why did they do that?????
