This reinforced corn header knife is the cutting component that severs the corn stalk at the base during harvest. It mounts to the gathering chain assembly of the corn header, where its leading edge contacts the stalk as the machine moves forward. The reinforcement along the blade body reduces flex under heavy crop loads, maintaining a consistent cutting angle. Wear on the cutting edge leads to ragged stalk cuts, which can increase header loss and leave stubble that interferes with subsequent tillage. The knife is designed to match the original mounting geometry of the header assembly, so the bolt pattern and hole alignment correspond to the factory attachment points.
