One New Aftermarket Replacement Middle Section, Fine Knife Assembly Fits John Deere 900 Series Draper Headers
This aftermarket replacement middle section is part of a sectionalized fine knife assembly designed for use on combine harvester draper cutting platforms. The middle section mounts to the cutter bar between the head and tail sections, carrying fine-tooth sickle sections that deliver clean, precise cutting in small grain, varying crop conditions, and green or weedy fields. Fine-tooth knife assemblies are the recommended choice when harvesting in uneven, green, or mixed-crop conditions where a coarser blade would struggle to maintain cut quality.
Sectionalized knife assemblies like this middle section are designed for easier handling, transport, and field replacement compared to one-piece sickles. Replacing only a damaged or worn middle section reduces downtime and cost versus replacing the entire knife assembly.
