Got a Steffen 950 accumulator flat stack that has ran maybe 100 thousands bales flawlessly. Now for some unknown reason after about 100 bales or so the baler fails to to tie. In other words the arm does not sweep the first two bales to the back. It just loads 8 and then dumps. It does this every three or four loads which makes it hard to pinpoint why. All the switches seem fine and I have swapped all the relays around. You can manually quick dump the first two that don't sweep and the next will load fine. Maybe someone here has had this problem?
