In addition, the packer drive and the pickup drive are slip clutch protected, while the stuffer drive, knotter assemblies and needle drive are shear bolt protected.

The heart of the drive system, however, is a rugged, dual-reduction (LB33 and LB34) or triple-reduction (LB44) gearbox that directs power from the tractor PTO to the rest of the baler without the need for extra chain drives and maintenance. A heavy, stress-relieved flywheel, that incorporates an overrunning clutch, helps maintain plunger momentum, while reducing vibration and shock loads to the tractor.
