[AT] older combine straw choppers

[Ralph Goff]

John, I've only ever had one combine with a straw chopper. The 550 Massey 
must have been a little out of balance right from the start as I could never 
keep a set of bearings in the chopper for long. It would vibrate at times 
and there were cracks forming in the rear sheet metal. I solved that problem 
(and several others) by trading the Massey in on a Case-IH axial flow with 
no chopper to balance or vibrate. The rotor breaks up the straw pretty well 
and there is no need for an extra straw chopper in my opinion. Others may 
differ. :-)

Ralph in Sask.
