Schumacher Disc Mower Knife | Replaces John Deere FH308235 | Radura PrimeLine | A0006
Genuine Schumacher A0006 | 18° right-hand rotary disc mower knife designed as a premium replacement for John Deere OEM FH308235 used on selected John Deere disc mowers, mower conditioners, swather platforms, headers, and windrower systems.
This knife is part of the Schumacher German Radura PrimeLine premium cutting line, built for consistent cut quality, durability, and long service life in demanding mowing conditions.
Why 18° twist mower knives?
The maximum-lift design helps move crop aggressively over the cutterbar for improved feeding, cleaner cutting, and strong crop flow in light, downed, or difficult crop conditions. It provides more lift than 14° or flatter low-angle knives while maintaining dependable cutting performance.
Important – How disc mower knives work:
Each cutter disc uses two knives that are mirror images of each other. These knives are not interchangeable. One knife mounts on one side of the disc, and the matching opposite knife mounts on the other side to keep the disc balanced and cutting correctly.
Schumacher A0006 corresponds to the knife commonly referenced as John Deere FH308235. It is one half of the required knife pair on the cutter disc. The matching opposite knife is Schumacher A0005, which replaces John Deere FH308234.
This is the clockwise / right-turning knife in the matched pair. Some suppliers describe knives as “left-hand” or “right-hand,” but those terms can change depending on how the disc is viewed. The most reliable way to identify the correct knife is by the part number, knife shape, twist angle, and mounting dimensions.
