I changed mine right after trading heads that was back when they came out with the auger drive on the right. run the 1.5 knife and it cuts good there are times I wish it even went faster.have had no trouble at all with drive-head since new.(25' on 2166)I usually change broken sections daily or sooner if they give trouble and switch sickles at about 500 acres. (have 2 spares)
