Cup Knives — Industrial Cutting Tools

Plain blades are standard steel, manufactured to OEM specifications. Hard-Faced blades have welding material applied to increase durability, typically offering twice the part life of plain blades. Super-Koat blades undergo a proprietary heat-treating process, delivering three or more times the service life of plain blades in highly abrasive environments.

Clean Cutter cup knives are compatible with a wide range of manufacturers including Balzer, Buffalo, Fox Brady, Hiniker, New Idea, Flory, Dandl, Rears, Alamo-Mott, Loftness, Maschio, and many others. A cross-reference system is available to help identify the correct replacement part for your specific equipment model.

Clean Cutter provides a manufacturer cross-reference guide online and through their technical support team. You can identify compatible parts by your equipment brand and original part number. For example, part 6022-718 replaces Balzer-12297, Buffalo-11040041, and Fox Brady-01694/1094. Contact support at (800) 345-2335 for assistance.

Cup knives should be replaced when visible wear, chipping, or reduced cutting efficiency is observed. In highly abrasive field conditions — such as rocky or sandy soils — blades wear faster. Upgrading to Hard-Faced or Super-Koat blades at replacement intervals can dramatically extend service life and reduce overall maintenance frequency.

Yes. All Clean Cutter cup knives are manufactured to the highest industry standards to match or exceed original equipment manufacturer (OEM) specifications. This ensures proper fit, balance, and cutting performance on compatible flail mower models without requiring any modifications to the equipment.

Clean Cutter offers standard cup knives, folded cup knives, scoop knives, and rolled eye designs. These are available in straight blade configurations and multiple hardness grades — Plain, Hard-Faced, and Super-Koat — to suit different flail mower models and operating environments from light vegetation management to heavy-duty brush cutting.
