摘要：
A knife head drive assembly for a header of an agricultural harvester including a knife head assembly for attachment to a forward end of the header. A first pivot arm and a second pivot arm are carried by the knife head assembly and are pivotably connected by a linkage. A rotating crank is operatively connected to and extending substantially transverse to the knife head assembly for engagement with a drive. A reciprocating shaft is connected to the rotating crank and either of the pivot arms or the linkage. Operation of the knife head drive assembly results in substantially linear, opposed oscillating motion of cutter bars carried by the knife head assembly.
