Yes, the sickle speed has been increased approx. 400 RPM I believe, (anybody may correct me, but I think I'm close). They are also using a 4" cut with a triple point in the middle. I believe this gives the crop more room to enter the cutting area and with the increased speed of the knifes it does an impressive job. I found it hard to drive 7mph only for comfort reasons. I could not make it strip however, (35 to 40 bushel beans). And yes everthing was new so that helped. 5.5 to 6.0 becomes very comfortable after a short while, and that alone is a step above anything I had run before. We ran beside a 930 that we thought was doing a good job, and there was a noticable difference. It is a fun head to operate.
