[AT] older combine straw choppers

[John Hall]

Your past problems are exactly what the guy I talked to mentioned. For the 
heck of it, I'll label everything that comes out so I can put it back if 
there is a problem.

 I've heard the rotary machines do well at breaking up straw but don't do 
much on soybean stems. With no-till, the more you can break it up the better 
off you are.

Now if we can escape this late season frost tonight, we just might have 
something to chop come June!

John
