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.

Adjustable stub guard assembly for corp cutting apparatus

A mowing device with two sickle bars provides an effective cutting action of the sickle bars at the center where they cooperate in their reciprocation. The knife guards of one sickle bar are mounted at a higher level than those of the other so that one overlaps the other by a height difference slightly greater than the thickness thereof. The central knife guard is of a modified construction so that the end most knife element of the upper sickle bar cooperates with the upper surface of the knife retaining plate member provided for the end knife element of the lower sickle bar. An additional trash bar is provided between the upper plate members for cooperation with the trash bars of the upper sickle bar.
