| On our 643 we put on the calmer slow down sprockets for the gathering chains, run it 1 to 1 and when we put new snapping rolls on which were just factory John Deere's we took the plasma cutter and cut windows in them just like the calmer rolls. It helped with feeding more even and really helped with butt shelling as it allowed the stalk to get back further into the head. It also allowed us to drive faster and do a better job. | |
