Abstract
A header for an agricultural harvester including a knife drive disposed at a forward end of a feeder conveyor. An infeed drive is disposed adjacent the feeder conveyor, the infeed drive having an input and an output. An input shaft is drivingly connected to the infeed drive input, and an output shaft has a first end connected to the infeed drive output and a second end drivingly connected to the knife drive. The knife drive can be a center knife drive and the infeed drive, the input shaft and the output shaft operate as a fully mechanical drive power supply for the center knife drive which overcomes the deficiencies of hydraulically-driven knife drives.
