Smooth Rasp Bar

The surface of this non-hardened bar has no serrations. The smooth surface helps to deliver a "softer", less aggressive threshing impact than a regular rasp bar. The thickness of this rasp bar is equal to a regular serrated rasp bar. This bar is only recommended for use in food corn, where the kernel's epidermal layer is usually very soft and delicate and therefore, prone to easy scuffing and/or cracking.

The smooth rasp bar is not recommended for use in corn where the stalks are damp or green or in crops that have green viney stems or are weed-infested. In these conditions, the flush even surface of the bar, can contribute to abrupt slug feeding and/or material buildup on the face of the concave.
