摘要： A cover assembly for a knife drive of an agricultural header includes a cover having a channel configured to receive a drive arm of the knife drive. The channel faces upwardly with respect to a vertical axis of the agricultural header, and a lateral extent of the channel is configured to enable the drive arm to oscillate to drive a blade support of a cutter bar assembly to oscillate. Furthermore, the cover has a front section and a rear section, the front section extends upwardly and rearwardly from a front end of the cover to the rear section, the rear section extends continuously downwardly and rearwardly from the front section to a rear end of the cover, and the rear section is configured to be angled less than 45 degrees relative to a longitudinal belt of the agricultural header.
