Abstract
The backing bar of the sickle overlies the cutter sections and is confined during its reciprocation within an elevated channel defined at the front by the rear ends of the tangs on the sickle guards and at the rear by the front ends of hold-down clips extending along and immediately behind the backing bar. No portions of the clips extend up and over the sickle, eliminating areas for crop clogging. The front ends of the clips overlie the rearmost edges of the cutter sections to maintain the sickle down against shearing surfaces on the uards.
