Knife Section (Sickle) Coarse Tooth 87728905

87728905 is a coarse serrated knife section used on combine header cutterbars. Fits Case IH and New Holland platforms, including models such as 3020, 3050, 3152 and similar draper and flex headers. It provides the cutting edge that slices crop stalks cleanly as the header moves through the crop. Worn knife sections cause poor cutting quality, increased fuel use, reduced harvest speed and risk of cutterbar damage. Replacing them restores sharp cutting performance and reliable operation. This is an aftermarket replacement part.
