3-Tine Knife Guard (SLS) H213508, H229540

H213508 is a standard-wear dual knife guard used on combine header cutterbars. Fits John Deere platform and draper headers, including models in the 600R, 600F, 600D, 900D and similar series. It supports and protects the cutterbar blades while guiding crop material for smooth, efficient cutting. Worn or broken knife guards cause poor cutting quality, vibration, and increased wear. Replacing them maintains clean cutting performance and reduces downtime. This is an aftermarket replacement part.
