Description
When your disc harrow starts pushing residue instead of cutting through it cleanly, it’s time to replace those worn blades with ones that’ll actually bite. This 20-inch crimp center disc blade brings back the aggressive cutting action that leaves crop stubble properly sized and mixed into the soil, instead of creating a matted mess that’ll haunt your planting season.
What You’re Getting
- Crimp center design provides superior strength and durability where it matters most
- Quality Osmundson construction from hardened Boron 15B26 steel that holds an edge through countless acres
- Smooth edge cuts cleanly through residue without the aggressive action of notched blades
- Single punch mounting system fits standard 1-1/8 inch square axle harrows
- 3/16 inch thickness provides the right balance of cutting ability and longevity
Built for Real Farm Work
This blade replaces OEM part number 197604A1 and fits disc harrows using 1-1/8 inch square axles. It’s designed for operators who need reliable residue management in medium to light tillage conditions where smooth cutting action works better than aggressive chopping.
Made to Last
The crimp center construction reinforces the hub area where stress concentrates during field work. The Boron 15B26 steel maintains the perfect hardness range – hard enough at 46-52 Rockwell to hold an edge through acres of tough tillage, but not so brittle it shatters when you clip that hidden field stone. No fancy coatings here – just quality steel that does the job.
Good to Know
When replacing blades, never mix worn and new on the same gang – the diameter difference creates uneven cutting that leaves mohawk strips. The single punch mounting means checking for elongated holes from wear – loose blades wobble and wear prematurely. Consider ordering a full gang set while you’re at it – shipping costs are often the same, and you’ll need them eventually anyway.
