Schumacher Disc Mower Knife | Replaces New Holland 84271205 | Radura PrimeLine | A00BQ
Genuine Schumacher A00BQ | Rotary disc mower knife for hay and forage cutting applications, designed to match the knife shape and mounting used on New Holland and Case IH disc mowers and mower conditioners.
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.
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 A00BQ corresponds to the knife commonly referenced as New Holland 84271205. It is one half of the required knife pair on the cutter disc. The matching opposite knife is Schumacher A00BR, which replaces New Holland 84271203.
This is the counterclockwise / left-hand 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 and knife shape. If your mower currently uses 84271205, this is the correct replacement knife.
Always replace knives in pairs on the same disc to maintain proper balance, smooth operation, and even cutting performance.
