There cannot be any hesitation of the crop at the cutterbar if a uniform windrow is to be produced. Knife sharpness and knife-to-guard fit contribute to a clean cut.
Use sharp knife. The rate of knife wear varies depending upon crop and field conditions.
A dull knife does not cut all stems cleanly causing an intermixing of cut and uncut stems. This intermix

interferes with the flow of the cut stems by the reel, causing rough stubble and an uneven windrow. The poor cutting action also necessitates a slower ground speed.
The cutterbar can be equipped with either regular guards or non-clog guards. Guards without a wear bar must be used at the knife-head end of cutterbar. (See Installing Regular Guards on Cutterbar or Installing Non-Clog Guards on Cutterbar in the Service section.)
