WCIN | I have a 1975 643 with tapered and notched straight rolls. I prefer the tapered. I see no noticeable difference, but I weld up the rolls every 800 acres.
When you return to the field the next day, then you notice the difference.
But, you can grind an edge on the flute. Gives it more aggressive stature.
edit- a 93 series cross auger sprocket helps with putting the outer drive chains to 1:1 ratio. It's bigger, so is slows the auger down. Takes some cutting, on mine anyway.
