AGV - B102873 - Cutterbar Head Claas 100144.0

This cutterbar head connects the reciprocating knife drive to the knife section on the header. It transmits the oscillating motion from the drive assembly to the cutterbar, converting rotational input into the back-and-forth cutting action. Wear at the pivot point or in the mounting bore leads to increased clearance, which causes knife chatter and uneven stubble height. The head is machined to match the original geometry so that the knife register and stroke length are maintained without shimming. On reinstallation, confirm that the retaining hardware is torqued to specification and that the knife sections align with the guards.
