This drive shaft transmits torque from the gearbox output to the feed-roller mechanism inside the baler. It is located in the drive system, connecting the power input to the rotating components that move crop material into the compression chamber. A worn or damaged shaft causes uneven feed-roller speed, leading to plugging or inconsistent bale density. As an original component, the shaft is machined to match the spline profile and length of the original assembly, ensuring correct engagement with the mating couplers without requiring shimming or modification.
