[QUOTE="Texasmark, post: 1577704, member: 27848"] No expert by any means but vibration is caused by unequal lengths of shafts and thus the advent of the "Constant Velocity" joint. The vibration comes from different rotational speeds caused by such so the CV makes the turn with equal lengths. 3 pts. it doesn't matter as the angle is seldom more than a few degrees (vertical) and the vibration is exponentially a function of the size of the angle between drive and driven shafts. My Previous JD 530 baler had a non CV jointed shaft but came with a drawbar extender and special connection forcing you to use the extender when using both the JD 1209 swather and the baler. Reason was equalizing shaft lengths to reduce vibration. The 1209 had a carrier bearing very near the PTO connector since the drive line was like 6'. The 1209, with the extender cut a 90* corner with no uncut crop and no noticeable vibration in the turn meaning you didn't have to come back and do your X across the field and pick up your corners and you weren't going to tear up your drive line. The current baler is a JD 375, (half the bale weight of the 530) and has a CV joint at the tractor PTO connector. Not a shredder per se, but a couple of examples of how JD decided to attack the problem. HTH. [/QUOTE]
