Disc Mower Knives
Since the late 1990s, when our team was heavily involved in setting the standards for disc mower knife (DMK) manufacturing and testing, Kondex has been leading the way in making DMKs. Because these knives spin at high rates of speed and have the potential to encounter obstacles during use, safety is of the utmost importance. Beyond safety, the performance of these knives is what sets our DMKs above the rest.
Disc mower knives are used on mower conditioners that are pushed or pulled by tractors. Typically, there are two DMKs mounted on opposite sides of oval discs — also referred to as turtle shells. Kondex DMKs are made to varying lengths, widths, twist angles, and mounting hole diameters. We supply these knives to all major OEMs, including new production and service components. Focusing on performance, Kondex DMKs offer many features that enable them to cut smoother, last longer, and operate more safely than other knives:
- Machined cutting edge delivers improved sharpness
- Milled edge stops before mount holes for greater structural strength
- Radial-twist design improves lifting action for a smoother cut
- Superior heat treatment provides greater impact absorption
There are no shortcuts when it comes to ensuring the quality, safety, and longevity of our disc mower knives (DMKs). We test and catalog our processes according to demanding ISO standards. Each knife is stamped with a traceable, unique sequential number as a commitment to quality control.
The following processes and tests have been put in place to ensure the integrity of our DMKs:
- Incoming material is inspected, then tagged for traceability
- Bend tests are performed to ensure ductility and resistance to cracking
- Impact tests are used to validate material toughness and prevent fast fracture breaks
- Metallurgical examination allows for in depth microstructural analysis ensuring proper heat treatment
