This chain is a drive component for the baler’s pickup or rotor assembly. It transmits rotary motion from the gearbox output to the intake mechanism that feeds crop material into the bale chamber. As a roller chain, it engages sprockets on both the driving and driven shafts; any elongation from wear causes timing slip between the pickup tines and the plunger stroke, leading to uneven bale density or plugging. The manufacturer’s original chain matches the pitch and tensile rating of the factory assembly, so no adjustment of the idler sprocket position is required during installation.
