Problems we have are trying to keep the drive end together, bushings are fine but the cheesy bar that connects under the wobbler box and runs the entire length of the head is not nearly strong enough, these engineers need to deal with this stuff out in the field. left hand reel sheet metal that turns with the reel fell apart around the grommets, dividers are nothing that can stand the abuse of running on the ground, we converted ours from 3" to 1.5", biggest mistake, lots of upkeep. The combine is a 2166 running 17.5' head I dont think it's a big enough head, bigger head= slower speeds and it will probably hold together better.
