Abstract

The adjustment between the stub guards of a sickle knife arrangement of a crop cutting apparatus is improved by the provision of an adjustment plate which is positioned between the upper stub guard and the support bar. The upper and lower stub guards are clamped onto the support bar by carriage bolts with the lower stub guard engaging against the under surface of the support bar and the upper stub guard engaging against the upper surface of the adjustment plate. The spacing and orientation of the adjustment plate relative to the support bar is adjusted by the three set screws which are threaded into the adjustment plate and engaged against the upper surface of the support bar. The adjustment technique is simple, requires few parts and avoids the necessity for shims.
