This roller chain transmits drive power from the tractor’s PTO or gearbox to the baler’s pick-up and packing mechanisms. It is a 16B-series chain with 132 links, designed for the high-torque, intermittent loads typical in baling operations. The chain wraps around sprockets on the drive system; as it rotates, it synchronizes the tine-bar and plunger movements. A worn or stretched chain causes timing slip, leading to uneven bale density and potential jams in the packing chamber. This original-manufacturer chain is made to the same pitch and roller diameter as the original assembly, so it seats correctly on the existing sprockets without requiring shimming or sprocket replacement. On installation, check sprocket wear and adjust chain tension to the specified slack before locking the idler.
