[AT] 3 point sickle bar

[Frank Vantacich]

I picked up a 3 point sickle bar mower and need some assistance on how it connects.  The 3 point connection and pto connection is straight forward.  The two things I am unsure of are a large spring and sections of chain that I guess is used to suspend the whole assembly and a solid shaft about 3 ft long with a  90 degree section containing a grease fitting. This shaft looks as though it goes under the rear of the tractor and connects to some place for what reason I do not know.  
   
  There are no id numbers or model name on the mower, it was painted green but don't think this was the original color.  As far as I can tell it doesn't ride on any wheels.  Is there a web site out there that would give me some guidance?
