This has happened twice now this summer. Both times, it's the same cluster of symptoms:
Main drive chain (the big 2060 from the plunger gearbox that drives the pickup, knotters and the tine bar behind the pickup) breaks.
The main shear pin breaks
The knotter shear pin breaks
The knotter drive chain gets stressed (first time it broke, I installed a new chain, second time, it actually moved it's tensioning pulley from the stress, but didn't break the chain)
The tine bar has symptoms: on the right (from the baler's perspective) side where the black, spring-loaded, tine is) The first time, I found that the spring was stretched so far that the tine had flipped right over to point towards the side of the baler opposite from the plunger...it should point down. The second time, the tine broke out completely from the end of the tine bar.
I don't have time today, our daughter is having a house-warming party...but I will post some pictures.
I know how to fix this, I can just replace the tine bar and the tines...put the chain back together and re-time
But....there must be some kind of root cause...
I'm not exactly sure of the conditions; as Pops (my father in law) was running the baler both times...but in both cases, it happened at the end of a piece, either driving across the headland or turning around.
