This pawl is a mechanical latch component located on the cutterbar of a grain harvester header. It engages with a mating notch on the drum to lock or release the drum during service or transport. When the pawl is engaged, it prevents the drum from rotating; when disengaged, it allows the drum to freewheel for maintenance access. A worn or bent pawl may fail to hold the drum securely, creating a safety risk during header work. The part is manufactured to match the original engagement geometry, ensuring it seats correctly in the notch without binding.
