[AJD] Two Cylinder JD's and Power Driven Equipment

[Duane Ledford]

Well, I've ran across several guys at shows that would rather let their display set 
than have a two cylinder tractor run them. Said they didn't want their machine torn 
up.  Also was looking through some old Two Cylinder magazines and found a write-in 
letter that was talking about not putting two cylinder tractors on equipment.  They 
sited a silage blower that kept ruining belts. They put a four cylinder tractor on 
the blower and no more trouble.  I suppose that it could be like previously posted, 
that more torque is exherted by the two cylinders, especilly on the PTO. I still 
lean toward this being propaganda. Just wondered if anyone had any real world or 
scientific data.
