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.\u003c\/p\u003e\u003cp\u003eSectionalized 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.\u003c\/p\u003e\u003ch4\u003eCompatible Models\u003c\/h4\u003e\u003cp\u003e\u003cstrong\u003eFits John Deere 900 Series Draper Headers:\u003c\/strong\u003e 925D, 930D, 936D (verify fitment against your specific header configuration before ordering)\u003c\/p\u003e\u003ch4\u003eReplaces Part Number(s):\u003c\/h4\u003e\u003cp\u003eA-MS900DF-AI\u003c\/p\u003e\u003cp\u003eNew aftermarket replacement part - not remanufactured, not used.\u003c\/p\u003e","brand":"Reliable Aftermarket Parts, Inc® -OD","offers":[{"title":"Default Title","offer_id":42896612098131,"sku":"A-MS900DF-AI","price":221.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0079\/4060\/3955\/files\/RAP_ComingSoon_Tractor_7e0dc0d6-2e58-4fd4-ab39-c71738446917.jpg?v=1757787783","url":"https:\/\/www.reliableaftermarketparts.co.uk\/products\/a-ms900df-ai-middle-section-fine-knife-assembly","provider":"Reliable Aftermarket Parts, Inc®","version":"1.0","type":"link"}
