Abstract
A reciprocating knife assembly of an agricultural implement includes first and second elongate reciprocating knives disposed along a leading edge of an agricultural implement, the reciprocating knives being disposed end to end and extending colinearly for simultaneous reciprocation in opposite directions, the first and second reciprocating knives being supported for sliding movement on the agricultural implement in a lateral direction generally perpendicular to the direction of travel of the agricultural implement as it travels through an agricultural field harvesting crop, a first bell crank coupled to the first reciprocating knife to reciprocate said knife, a second bell crank coupled to the second reciprocating knife to reciprocate the second reciprocating knife, and a common drive coupled to the first and second bell cranks to drive both the first and second bell cranks in opposite directions simultaneously.
